• What is the recommend way to get the main Activity from child Activity

  - by michael

  Hi, My android application has 1 main activity. And it launches some sub-activity (which I wrote) and that also launches some sub-activity (which I wrote). I do this: Intent i = new Intent("my intent1"); startActivity(i); My question is how can each of my sub-activity and sub-sub-activity get back to the Parent activity? Thank you.

• Hello-World-grade landscape Android app fails to start (complete code included)

  - by WingedCat

  I'm trying to develop a simple Android app, fixed in landscape mode. I am using Eclipse 1.3, compiling for Android SDK version 7 (OS version 2.1). When I try to run it in the emulator, it crashes on boot. (It gets as far as the unlock slider, but shortly after that when trying to launch the application itself, I get "The application Failtest (process com.wcs.failtest) has stopped unexpectedly. Please try again.".) Here is main.xml (with the tags escaped so this displays properly): <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="480px" android:layout_height="320px" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="96px" android:layout_height="320px" android:id="@+id/action_menu" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="96px" android:layout_height="48px" > <Button android:layout_width="48px" android:layout_height="48px" android:background="#f00" android:id="@+id/action_button_11" /> </LinearLayout> </LinearLayout> </LinearLayout> Here is AndroidManifest.xml (again with the tags escaped so this displays properly): <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.wcs.failtest" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar.Fullscreen"> <activity android:name=".FailtestActivity" android:screenOrientation="landscape" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="7" /> </manifest> And here is FailtestActivity.java: package com.wcs.failtest; import android.app.Activity; import android.os.Bundle; import android.widget.Button; import android.view.View.OnClickListener; import android.view.View; public class FailtestActivity extends Activity { private OnClickListener action11Listener = new OnClickListener() { public void onClick(View v) { } }; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Button button; button = (Button)findViewById(R.id.action_button_11); button.setOnClickListener(action11Listener); setContentView(R.layout.main); } } I suspect it is something simple I'm overlooking. What is it?

• Using android gesture on top of menu buttons

  - by chriacua

  What I want is to have an options menu where the user can choose to navigate the menu between: 1) touching a button and then pressing down on the trackball to select it, and 2) drawing predefined gestures from Gestures Builder As it stands now, I have created my buttons with OnClickListener and the gestures with GestureOverlayView. Then I select starting a new Activity depending on whether the using pressed a button or executed a gesture. However, when I attempt to draw a gesture, it is not picked up. Only pressing the buttons is recognized. The following is my code: public class Menu extends Activity implements OnClickListener, OnGesturePerformedListener { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //create TextToSpeech myTTS = new TextToSpeech(this, this); myTTS.setLanguage(Locale.US); //create Gestures mLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures); if (!mLibrary.load()) { finish(); } // Set up click listeners for all the buttons. View playButton = findViewById(R.id.play_button); playButton.setOnClickListener(this); View instructionsButton = findViewById(R.id.instructions_button); instructionsButton.setOnClickListener(this); View modeButton = findViewById(R.id.mode_button); modeButton.setOnClickListener(this); View statsButton = findViewById(R.id.stats_button); statsButton.setOnClickListener(this); View exitButton = findViewById(R.id.exit_button); exitButton.setOnClickListener(this); GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); } public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { ArrayList<Prediction> predictions = mLibrary.recognize(gesture); // We want at least one prediction if (predictions.size() > 0) { Prediction prediction = predictions.get(0); // We want at least some confidence in the result if (prediction.score > 1.0) { // Show the gesture Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show(); //User drew symbol for PLAY if (prediction.name.equals("Play")) { myTTS.shutdown(); //connect to game // User drew symbol for INSTRUCTIONS } else if (prediction.name.equals("Instructions")) { myTTS.shutdown(); startActivity(new Intent(this, Instructions.class)); // User drew symbol for MODE } else if (prediction.name.equals("Mode")){ myTTS.shutdown(); startActivity(new Intent(this, Mode.class)); // User drew symbol to QUIT } else { finish(); } } } } @Override public void onClick(View v) { switch (v.getId()){ case R.id.instructions_button: startActivity(new Intent(this, Instructions.class)); break; case R.id.mode_button: startActivity(new Intent(this, Mode.class)); break; case R.id.exit_button: finish(); break; } } Any suggestions would be greatly appreciated!

• Android: GPS location updates when the cellphone is in sleep?

  - by wei

  I need to update the location through GPS in the background even when the phone is in sleep. I am thinking to use AlarmManager to broadcast an Intent and then a receiver will call requestLocationUpdates() on LocationManager. But I am not sure whether it's guaranteed that the GPS location will be updated when the phone is in sleep and an intent will be broadcasted if I registered a PendingIntent when call requestLocationUpdates()? thanks,

• how to make the android app load faster?

  - by Tapan Desai

  I have designed an application for android, in which i am showing a splash screen before the main activity is started but the application takes 5-7 seconds to start on low-end devices. I want to reduce that time to as low as possible. I have been trying to reduce the things to be done in onCreate() but now i cannot remove any thing more from that. I am pasting the code that i have used to show the splash and the code from MainActivity. Please help me in reducing the startup time of the application. Splash.java @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_splash); txtLoad = (TextView) findViewById(R.id.txtLoading); txtLoad.setText("v1.0"); new Thread() { public void run() { try { sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } finally { finish(); Intent intent = new Intent(SplashActivity.this,MainActivity.class); startActivity(intent); } } }.start(); } MainActivity.java @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_main); editType1UserName = (EditText) findViewById(R.id.editTextType1UserName); editType1Password = (EditText) findViewById(R.id.editTextType1Password); editType2UserName = (EditText) findViewById(R.id.editTextType2UserName); editType2Password = (EditText) findViewById(R.id.editTextType2Password); editType3UserName = (EditText) findViewById(R.id.editTextType3UserName); editType3Password = (EditText) findViewById(R.id.editTextType3Password); editType4UserName = (EditText) findViewById(R.id.editTextType4UserName); editType4Password = (EditText) findViewById(R.id.editTextType4Password); mTxtPhoneNo = (AutoCompleteTextView) findViewById(R.id.mmWhoNo); mTxtPhoneNo.setThreshold(1); editText = (EditText) findViewById(R.id.editTextMessage); spinner1 = (Spinner) findViewById(R.id.spinnerGateway); btnsend = (Button) findViewById(R.id.btnSend); btnContact = (Button) findViewById(R.id.btnContact); btnsend.setOnClickListener((OnClickListener) this); btnContact.setOnClickListener((OnClickListener) this); mPeopleList = new ArrayList<Map<String, String>>(); PopulatePeopleList(); mAdapter = new SimpleAdapter(this, mPeopleList, R.layout.custcontview, new String[] { "Name", "Phone", "Type" }, new int[] { R.id.ccontName, R.id.ccontNo, R.id.ccontType }); mTxtPhoneNo.setAdapter(mAdapter); mTxtPhoneNo.setOnItemClickListener((OnItemClickListener) this); readPerson(); Panel panel; topPanel = panel = (Panel) findViewById(R.id.mytopPanel); panel.setOnPanelListener((OnPanelListener) this); panel.setInterpolator(new BounceInterpolator(Type.OUT)); getLoginDetails(); }

• Android ACTION_SEND Attached File

  - by Sean

  When you attach a file to an e-mail using the ACTION_SEND intent (with the extra EXTRA_STREAM) does the e-mail app copy that attached file to its own location? My app creates a file and attaches it to an email, but this can happen many times and I would like to be able to delete this file when it is no longer needed (so it doesn't flood the user's storage with junk data). Is the file safe to delete after the e-mail intent has started?

• Android Bluetooth Fails to Pair

  - by CaseyB

  I am having a problem getting my devices to pair in Android. If I go into the settings and pair them manually I can get them to connect using the following code: Server // Make sure the device it discoverable mServerSocket = mAdapter.listenUsingRfcommWithServiceRecord("Moo Productions Bluetooth Server", mUUID); mState = State.ACCEPTING; BluetoothSocket socket = mServerSocket.accept(); mServerSocket.close(); connected(socket); Client Set<BluetoothDevice> pairedDevices = mAdapter.getBondedDevices(); BluetoothSocket socket = null; // Search the list of paired devices for the right one for(BluetoothDevice device : pairedDevices) { try { mState = State.SEARCHING; socket = device.createRfcommSocketToServiceRecord(mUUID); mState = State.CONNECTING; socket.connect(); connected(socket); break; } catch (IOException e) { socket = null; continue; } } But if the devices hadn't already been paired it gets out of the foreach without connecting to a valid socket. In that case I start discovering. // If that didn't work, discover if(socket == null) { mState = State.SEARCHING; mReceiver = new SocketReceiver(); mContext.registerReceiver(mReceiver, new IntentFilter(BluetoothDevice.ACTION_FOUND)); mAdapter.startDiscovery(); } // ... Later ... private class SocketReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if(BluetoothDevice.ACTION_FOUND.equals(intent.getAction())) { try { // Get the device and try to open a socket BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); BluetoothSocket socket = device.createRfcommSocketToServiceRecord(mUUID); mState = State.CONNECTING; socket.connect(); // This is our boy, so stop looking mAdapter.cancelDiscovery(); mContext.unregisterReceiver(mReceiver); connected(socket); } catch (IOException ioe) { ioe.printStackTrace(); } } } } But it will never find the other device. I never get a pairing dialog and when I step through I see that it discovers the correct device, but it fails to connect with this exception java.io.IOException: Service discovery failed. Any ideas as to what I'm missing?

• Prevent an Activity from being killed by the OS while starting a child activity

  - by Martin Marinov

  I have a main activity which calls a child one via Intent I = new Intent(this, Child.class); startActivityForResult(I, 0); But as soon as Child becomes visible the main activity gets its onStop and immediately after that onDestroy method triggered. And as soon as I call finish() within the Child activity or press the back button, the Child activity closes and the home screen shows (instead of the main activity). How can I prevent the main activity from being destroyed? :\

• Application not showing up in Google Play for 4.x devices

  - by Zargle

  I recently posted about the Play store not letting me publish my app without a minSdkVersion, but whenever I set it to anything above "1" my app just doesn't work (minSdkVersion breaking program). So this guy suggested to just set my minSdkVersion to 1, which worked. But now when I submitted my app even though the developer site says: API level: 1-16+ Supported screens: normal-xlarge OpenGL textures: all But the app only shows it supports Android under 4.x, I developed it on my 4.0.4 device. I tried searching around and I found that some people have problems with services messing up the phones it supports, so I deleted all of my services, because I don't really need any for this version of the app to submit. And it still didn't work. So I don't know what else to do, here is my AndroidManifest.xml if it helps... I've been trying to figure out why my application isn't working for a week now, still nothing. I have tried setting a targetSdkVersion to something like 14, my application still breaks. I cleaned out my code, taking everything out of the already short, 200 lines, application, and it still isn't working. Is there something I can't use in an android application 4.0 that I am using in my application? or is it just my AndroidManifest? Thank you so much! <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unparalleledsoftware.app.list" android:versionCode="5" android:versionName="2.02" > <uses-sdk android:minSdkVersion="1" /> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".MainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> I should note,I am using the Theme.Holo.Light, but even if I change it to DeviceDefault it doesn't work. Edit: I googled the app on my friends Samsung Galaxy S3 (it didn't show up in the Play Store on his phone), when I installed by googling the app and hitting the "install" button on google and it opened in the Google Play store and was able to install. When I did the same on my phone, Galaxy Note, it opened in the Google Play Store, but then said "Not compatible." Why? They are both on the same version of OS. Why is mine not compatible, nor the One X compatible, but the Samsung Galaxy S3 worked...? Edit: I get these errors/problems when compiling with a targetSdkVersion, http://pastebin.com/mxgWNLdM

• Calling a JAVA method from C++ with JNI, no parameters

  - by PRNDL Development Studios

  Please bear with me, I am an iPhone developer and this whole android this confuses me a bit. I have some c++ methods that are called from a cocos2d-x CCMenuItem. Therefore I cannot send any parameters, according to the docs. I need to open a url with the android browser which will require me to call a JAVA function to start a new intent. I understand that I need to create a VM, however the below code gives me the error: jni/../../Classes/MyClass.cpp:184: error: 'JNI_CreateJavaVM' was not declared in this scope I was looking at this thread: Calling a java method from c++ in Android But he uses parameters, and I can't do that. And I don't see where those are in his code to just make them myself. I don't know what the string should be in the 'Find Class' method. Also, I assume it is pretty terrible to create a new VM instance in every method I need to call. How would I create one as a singleton to use across the board? This is my c++ code called by my menu item: #include <jni.h> ... JavaVM *vm; // Global ... void OptionsScene::website(){ JNIEnv *env; JavaVMInitArgs vm_args; vm_args.version = JNI_VERSION_1_2; vm_args.nOptions = 0; vm_args.ignoreUnrecognized = 1; jint result = JNI_CreateJavaVM(&vm, (void **)&env, &vm_args); // This line still errors jclass clazz = env->FindClass("com/prndl/project/WebExecute"); jmethodID method = env->GetMethodID(clazz, "website", "(Ljava/lang/String;)V"); env->CallVoidMethod(NULL,method); vm->DestroyJavaVM(); And this is the JAVA Method that I need to call: public class WebExecute extends Activity{ public void website(){ Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com")); startActivity(browserIntent); } } Honestly, I am struggling with this, any help is appreciated. Thanks.

• How to save/retrieve words to/from SQlite database?

  - by user998032

  Sorry if I repeat my question but I have still had no clues of what to do and how to deal with the question. My app is a dictionary. I assume that users will need to add words that they want to memorise to a Favourite list. Thus, I created a Favorite button that works on two phases: short-click to save the currently-view word into the Favourite list; and long-click to view the Favourite list so that users can click on any words to look them up again. I go for using a SQlite database to store the favourite words but I wonder how I can do this task. Specifically, my questions are: Should I use the current dictionary SQLite database or create a new SQLite database to favorite words? In each case, what codes do I have to write to cope with the mentioned task? Could anyone there kindly help? Here is the dictionary code: package mydict.app; import java.util.ArrayList; import android.database.Cursor; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteException; import android.util.Log; public class DictionaryEngine { static final private String SQL_TAG = "[MyAppName - DictionaryEngine]"; private SQLiteDatabase mDB = null; private String mDBName; private String mDBPath; //private String mDBExtension; public ArrayList<String> lstCurrentWord = null; public ArrayList<String> lstCurrentContent = null; //public ArrayAdapter<String> adapter = null; public DictionaryEngine() { lstCurrentContent = new ArrayList<String>(); lstCurrentWord = new ArrayList<String>(); } public DictionaryEngine(String basePath, String dbName, String dbExtension) { //mDBExtension = getResources().getString(R.string.dbExtension); //mDBExtension = dbExtension; lstCurrentContent = new ArrayList<String>(); lstCurrentWord = new ArrayList<String>(); this.setDatabaseFile(basePath, dbName, dbExtension); } public boolean setDatabaseFile(String basePath, String dbName, String dbExtension) { if (mDB != null) { if (mDB.isOpen() == true) // Database is already opened { if (basePath.equals(mDBPath) && dbName.equals(mDBName)) // the opened database has the same name and path -> do nothing { Log.i(SQL_TAG, "Database is already opened!"); return true; } else { mDB.close(); } } } String fullDbPath=""; try { fullDbPath = basePath + dbName + "/" + dbName + dbExtension; mDB = SQLiteDatabase.openDatabase(fullDbPath, null, SQLiteDatabase.OPEN_READWRITE|SQLiteDatabase.NO_LOCALIZED_COLLATORS); } catch (SQLiteException ex) { ex.printStackTrace(); Log.i(SQL_TAG, "There is no valid dictionary database " + dbName +" at path " + basePath); return false; } if (mDB == null) { return false; } this.mDBName = dbName; this.mDBPath = basePath; Log.i(SQL_TAG,"Database " + dbName + " is opened!"); return true; } public void getWordList(String word) { String query; // encode input String wordEncode = Utility.encodeContent(word); if (word.equals("") || word == null) { query = "SELECT id,word FROM " + mDBName + " LIMIT 0,15" ; } else { query = "SELECT id,word FROM " + mDBName + " WHERE word >= '"+wordEncode+"' LIMIT 0,15"; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); int indexWordColumn = result.getColumnIndex("Word"); int indexContentColumn = result.getColumnIndex("Content"); if (result != null) { int countRow=result.getCount(); Log.i(SQL_TAG, "countRow = " + countRow); lstCurrentWord.clear(); lstCurrentContent.clear(); if (countRow >= 1) { result.moveToFirst(); String strWord = Utility.decodeContent(result.getString(indexWordColumn)); String strContent = Utility.decodeContent(result.getString(indexContentColumn)); lstCurrentWord.add(0,strWord); lstCurrentContent.add(0,strContent); int i = 0; while (result.moveToNext()) { strWord = Utility.decodeContent(result.getString(indexWordColumn)); strContent = Utility.decodeContent(result.getString(indexContentColumn)); lstCurrentWord.add(i,strWord); lstCurrentContent.add(i,strContent); i++; } } result.close(); } } public Cursor getCursorWordList(String word) { String query; // encode input String wordEncode = Utility.encodeContent(word); if (word.equals("") || word == null) { query = "SELECT id,word FROM " + mDBName + " LIMIT 0,15" ; } else { query = "SELECT id,content,word FROM " + mDBName + " WHERE word >= '"+wordEncode+"' LIMIT 0,15"; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); return result; } public Cursor getCursorContentFromId(int wordId) { String query; // encode input if (wordId <= 0) { return null; } else { query = "SELECT id,content,word FROM " + mDBName + " WHERE Id = " + wordId ; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); return result; } public Cursor getCursorContentFromWord(String word) { String query; // encode input if (word == null || word.equals("")) { return null; } else { query = "SELECT id,content,word FROM " + mDBName + " WHERE word = '" + word + "' LIMIT 0,1"; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); return result; } public void closeDatabase() { mDB.close(); } public boolean isOpen() { return mDB.isOpen(); } public boolean isReadOnly() { return mDB.isReadOnly(); } } And here is the code below the Favourite button to save to and load the Favourite list: btnAddFavourite = (ImageButton) findViewById(R.id.btnAddFavourite); btnAddFavourite.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // Add code here to save the favourite, e.g. in the db. Toast toast = Toast.makeText(ContentView.this, R.string.messageWordAddedToFarvourite, Toast.LENGTH_SHORT); toast.show(); } }); btnAddFavourite.setOnLongClickListener(new View.OnLongClickListener() { @Override public boolean onLongClick(View v) { // Open the favourite Activity, which in turn will fetch the saved favourites, to show them. Intent intent = new Intent(getApplicationContext(), FavViewFavourite.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); getApplicationContext().startActivity(intent); return false; } }); }

• How can i use the Orientation correct for images

  - by user3578109

  I´m learning android/java by myself @the moment and i have a problem with a part of my app i´m learning on. I made the code with help of the www and my problem is that if i open an image from the gallery it´s send to the edit activity but in the activity pictures what are made in portrait mode are displayed always wrong (90° to the right side).... The codes are Matrix private Bitmap rotateBitmapToOrientation(Bitmap b, int orientation){ Matrix matrix = new Matrix(); matrix.postRotate(orientation); Canvas offscreenCanvas = new Canvas(); offscreenCanvas.drawBitmap(b, matrix, null); return b; } and the other one @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case PICK_IMAGE_FROM_GALLERY: { if (resultCode == RESULT_OK) { Log.d(TAG, "Got Picture!"); Log.d(TAG,"File type - " + data.getType()); Uri photoUri = data.getData(); if (photoUri != null) { try { String[] filePathColumn = {MediaStore.Images.Media.DATA}; String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION}; int orientation = -1; Cursor cursor = getContentResolver().query(photoUri, filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(filePathColumn[0]); String filePath = cursor.getString(columnIndex); cursor.close(); cursor = getContentResolver().query(photoUri, orientationColumn, null, null, null); if(cursor != null && cursor.moveToFirst()){ orientation = cursor.getInt(cursor.getColumnIndex(orientationColumn[0])); } cursor.close(); HashMap<String, Integer> pRes = this.getImageResolutionSetting(); Bitmap shrunkenBitmap = FileUtilsHelper.shrinkBitmap(filePath, pRes.get("width"), pRes.get("height")); shrunkenBitmap = rotateBitmapToOrientation(shrunkenBitmap, orientation); String res = FileUtilsHelper.saveBitmapAsJpeg(shrunkenBitmap, this); Log.d(TAG,"File Path: " + res); shrunkenBitmap.recycle(); Intent editImage = new Intent(this, EditImage.class); editImage.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT); editImage.putExtra("stuff.path", res); startActivity(editImage); }catch(Exception e){ Toast.makeText(this, R.string.cant_save_image,Toast.LENGTH_SHORT).show(); } } } } break; } }} I don´t know what i´m doing wrong... I could really need a teacher on that :) Thx for your help dudes!!

• Android - creating a custom preferences activity screen

  - by Bill Osuch

  Android applications can maintain their own internal preferences (and allow them to be modified by users) with very little coding. In fact, you don't even need to write an code to explicitly save these preferences, it's all handled automatically! Create a new Android project, with an intial activity title Main. Create two more activities: ShowPrefs, which extends Activity Set Prefs, which extends PreferenceActivity Add these two to your AndroidManifest.xml file: <activity android:name=".SetPrefs"></activity> <activity android:name=".ShowPrefs"></activity> Now we'll work on fleshing out each activity. First, open up the main.xml layout file and add a couple of buttons to it: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"> <Button android:text="Edit Preferences"    android:id="@+id/prefButton"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_gravity="center_horizontal"/> <Button android:text="Show Preferences"    android:id="@+id/showButton"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_gravity="center_horizontal"/> </LinearLayout> Next, create a couple button listeners in Main.java to handle the clicks and start the other activities: Button editPrefs = (Button) findViewById(R.id.prefButton);       editPrefs.setOnClickListener(new View.OnClickListener() {              public void onClick(View view) {                  Intent myIntent = new Intent(view.getContext(), SetPrefs.class);                  startActivityForResult(myIntent, 0);              }      });           Button showPrefs = (Button) findViewById(R.id.showButton);      showPrefs.setOnClickListener(new View.OnClickListener() {              public void onClick(View view) {                  Intent myIntent = new Intent(view.getContext(), ShowPrefs.class);                  startActivityForResult(myIntent, 0);              }      }); Now, we'll create the actual preferences layout. You'll need to create a file called preferences.xml inside res/xml, and you'll likely have to create the xml directory as well. Add the following xml: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> </PreferenceScreen> First we'll add a category, which is just a way to group similar preferences... sort of a horizontal bar. Add this inside the PreferenceScreen tags: <PreferenceCategory android:title="First Category"> </PreferenceCategory> Now add a Checkbox and an Edittext box (inside the PreferenceCategory tags): <CheckBoxPreference    android:key="checkboxPref"    android:title="Checkbox Preference"    android:summary="This preference can be true or false"    android:defaultValue="false"/> <EditTextPreference    android:key="editTextPref"    android:title="EditText Preference"    android:summary="This allows you to enter a string"    android:defaultValue="Nothing"/> The key is how you will refer to the preference in code, the title is the large text that will be displayed, and the summary is the smaller text (this will make sense when you see it). Let's say we've got a second group of preferences that apply to a different part of the app. Add a new category just below the first one: <PreferenceCategory android:title="Second Category"> </PreferenceCategory> In there we'll a list with radio buttons, so add: <ListPreference    android:key="listPref"    android:title="List Preference"    android:summary="This preference lets you select an item in a array"    android:entries="@array/listArray"    android:entryValues="@array/listValues" /> When complete, your full xml file should look like this: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">  <PreferenceCategory android:title="First Category"> <CheckBoxPreference    android:key="checkboxPref"    android:title="Checkbox Preference"    android:summary="This preference can be true or false"    android:defaultValue="false"/> <EditTextPreference    android:key="editTextPref"    android:title="EditText Preference"    android:summary="This allows you to enter a string"    android:defaultValue="Nothing"/>  </PreferenceCategory>  <PreferenceCategory android:title="Second Category">   <ListPreference    android:key="listPref"    android:title="List Preference"    android:summary="This preference lets you select an item in a array"    android:entries="@array/listArray"    android:entryValues="@array/listValues" />  </PreferenceCategory> </PreferenceScreen> However, when you try to save it, you'll get an error because you're missing your array definition. To fix this, add a file called arrays.xml in res/values, and paste in the following: <?xml version="1.0" encoding="utf-8"?> <resources>  <string-array name="listArray">      <item>Value 1</item>      <item>Value 2</item>      <item>Value 3</item>  </string-array>  <string-array name="listValues">      <item>1</item>      <item>2</item>      <item>3</item>  </string-array> </resources> Finally (for the preferences screen at least...) add the code that will display the preferences layout to the SetPrefs.java file:  @Override     public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      addPreferencesFromResource(R.xml.preferences);      } OK, so now we've got an activity that will set preferences, and save them without the need to write custom save code. Let's throw together an activity to work with the saved preferences. Create a new layout called showpreferences.xml and give it three Textviews: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"> <TextView   android:id="@+id/textview1"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="textview1"/> <TextView   android:id="@+id/textview2"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="textview2"/> <TextView   android:id="@+id/textview3"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="textview3"/> </LinearLayout> Open up the ShowPrefs.java file and have it use that layout: setContentView(R.layout.showpreferences); Then add the following code to load the DefaultSharedPreferences and display them: SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);    TextView text1 = (TextView)findViewById(R.id.textview1); TextView text2 = (TextView)findViewById(R.id.textview2); TextView text3 = (TextView)findViewById(R.id.textview3);    text1.setText(new Boolean(prefs.getBoolean("checkboxPref", false)).toString()); text2.setText(prefs.getString("editTextPref", "<unset>"));; text3.setText(prefs.getString("listPref", "<unset>")); Fire up the application in the emulator and click the Edit Preferences button. Set various things, click the back button, then the Edit Preferences button again. Notice that your choices have been saved.   Now click the Show Preferences button, and you should see the results of what you set:   There are two more preference types that I did not include here: RingtonePreference - shows a radioGroup that lists your ringtones PreferenceScreen - allows you to embed a second preference screen inside the first - it opens up a new set of preferences when clicked

• Android app crashes on emulator - logCat shows no errors

  - by David Miler

  I have just added the SherlockActionBar library to my android project. After some small changes (FragmentActivity - SherlockFragmentActivity, getActionBar() - getSupportActionBar(), imports) it all compiled nicely. After I run the app, however, the debugger stops, as though it had encountered an exception. However, there are no errors shown in the LogCat output. I just can't wrap my head around what's going on. Here is the logCat output after I terminate the app. 10-02 14:11:19.227: I/SystemUpdateService(174): UpdateTask at time 1349187079227 10-02 14:11:19.237: I/ActivityThread(328): Pub com.android.email.attachmentprovider: com.android.email.provider.AttachmentProvider 10-02 14:11:19.687: I/dalvikvm(81): Jit: resizing JitTable from 512 to 1024 10-02 14:11:19.809: D/MediaScannerService(150): start scanning volume internal: [/system/media] 10-02 14:11:20.047: V/AlarmClock(239): AlarmInitReceiver finished 10-02 14:11:20.087: I/ActivityManager(81): Start proc com.android.quicksearchbox for broadcast com.android.quicksearchbox/.SearchWidgetProvider: pid=346 uid=10012 gids={3003} 10-02 14:11:20.127: D/ExchangeService(320): !!!
