• "Scheduling restart of crashed service", but no call to onStart() follows

  - by kostmo

  In the 1.6 API, is there a way to ensure that the onStart() method of a Service is called after the service is killed due to memory pressure? From the logs, it seems that the "process" that the service belongs to is restarted, but the service itself is not. I have placed a Log.d() call in the onStart() method, and this is not reached. To test my service under memory pressure, I spawn it from an activity, then launch the web browser and visit some Javascript-heavy websites like Slashdot until my service is killed. The logcat reads: 03-07 16:44:13.778: INFO/ActivityManager(52): Process com.kostmo.charbuilder.full (pid 2909) has died. 03-07 16:44:13.778: WARN/ActivityManager(52): Scheduling restart of crashed service com.kostmo.charbuilder.full/com.kostmo.charbuilder.DownloadImagesService in 5000ms 03-07 16:44:13.778: INFO/ActivityManager(52): Low Memory: No more background processes. 03-07 16:44:13.778: ERROR/ActivityThread(52): Failed to find provider info for android.server.checkin 03-07 16:44:13.778: WARN/Checkin(52): Can't log event SYSTEM_SERVICE_LOOPING: java.lang.IllegalArgumentException: Unknown URL content://android.server.checkin/events 03-07 16:44:18.908: INFO/ActivityManager(52): Start proc com.kostmo.charbuilder.full for service com.kostmo.charbuilder.full/com.kostmo.charbuilder.DownloadImagesService: pid=3560 uid=10027 gids={3003, 1015} 03-07 16:44:19.868: DEBUG/ddm-heap(3560): Got feature list request 03-07 16:44:20.128: INFO/ActivityThread(3560): Publishing provider com.kostmo.charbuilder.full.provider.character: com.kostmo.charbuilder.provider.ImageFileContentProvider

• Android - ListActivity, add Header and Footer view

  - by Victor

  I'm using ListActivity, listview. listView = getListView(); just working perfectly. I added footer view as LayoutInflater inflater = getLayoutInflater(); listView.addFooterView( inflater.inflate( R.layout.footer, null ), null, false); and everything was shiny but ugly, so i wanted to add this footer view (which contains only 1 edittext and only 1 button ) to header of listView as LayoutInflater inflater = getLayoutInflater(); listView.addHeaderView( inflater.inflate( R.layout.footer, null ), null, false); and suddenly everything goes wrong, and i get RuntimeException immediately. Suspended(exception RuntimeException) ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) ActivityThread.handleLaunchActivity(ActivityThread$ActivityRecord, Intent) ActivityThread.access$2200(ActivityThread, Activity$ActiviyRecord, Intent), so on.. Why is it throws exception ? What is different between addFooterView and addHeaderView, and how can i add Header to ListActivity ? UPDATE So as you can read in comments, my logcat still doesn't work, but i just tried next at this moment: } catch(Exception e){ Writer result = new StringWriter(); PrintWriter printWriter = new PrintWriter(result); e.printStackTrace(printWriter); String error = result.toString(); } and afterward i put breakpoint, and i can read error in expressions section. it said : java.lang.IllegalStateException: Cannot add header view to list -- setAdapter has already been called. it was instructive for all of us. After change sort of commands, it works perferctly.

• Issue in achartengine jar file

  - by Anshuman

  Actually i have created an app in which i have used achartengine to contruct graph. It was running ok, but today i saw an update for android SDK to r17. Once i upadated the sdk the app i had build started crash. In the logcat i show the following error report.

• Streaming Media Player Tutorial Stops Unexpectedly. How Should I Debug (And Other Questions From A

  - by Danny

  Hello! I'm a fledgling in the Android and Eclipse ways. I was reading and downloaded the source code for a Streaming Media Player tutorial from Pocket Journey, here. However, when I try to run it through the "Run As..." or "Debug As..." features in Eclipse, the emulator reports: "Sorry! The application Android Tutorials (process com.pocketjourney.tutorials) has stopped unexpectedly. Please try again." Now, from stepping through the Tutorial 1 activity (for those of you that may be familiar with it), it seems something funky happens here: button.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Toast.makeText(Tutorial1.this, "Button Clicked",Toast.LENGTH_SHORT).show(); }}); My questions are: What's up with that line? Apparently, other comments haven't had this problem; am I missing some library that I should be downloading from someplace? How should I go about debugging this other than/in addition to stepping through code? I'm used to Visual Studio, which has a nice box with exception details for me to sift through and copy/paste to google with. Eclipse debugging showed a "No Source Code" page, or a list of exceptions. I've heard of something called LogCat; is that relevant here? Thanks in advance!

• Android 1.5/1.6 issue with style and autogenerated R.java file

  - by Gaks

  I'm having strange issue with R.java file and styles defined in my resources. Here's some code: In res/values/strings.xml: <style parent="android:Theme.Dialog" name="PopupWindowStyle"> <item name="android:windowBackground">@drawable/bg1</item> <item name="android:textColor">@android:color/black</item> </style> In AndroidManifest.xml: <activity android:name=".RegisterScreen" android:icon="@drawable/ico" android:label="@string/applicationName" android:theme="@style/PopupWindowStyle" android:configChanges="locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|fontScale"> </activity> In autogenerated gen/.../R.java: public static final class style { public static final int PopupWindowStyle=0x7f090000; } After some changes in the project, eclipse changed autogenerated value for PopupWindowStyle from 0x7f080000 to 0x7f090000. After that, on Android 1.5, RegisterScreen activity is displayed without PopupWindowStyle style - there is an error displayed in logcat: Skipping entry 0x7f090000 in package table 0 because it is not complex! On Android 1.6 however everything works fine - PopupWindowStyle works like it was before it's integer value has changed. I was testing this issue, by reverting the source code to older revisions. I can confirm, that this problem started occurring after src code commit, which changed two files completely unrelated to this part of code - and an autogenerated R.java file. Any idea what could cause that?

• Android: Cannot get the httpPost params but can get the httpGet from php

  - by jjLin

  Here is my android code to send request: // defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(serverUrl); List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("abc", "abc2")); httpPost.setEntity(new UrlEncodedFormEntity(params)); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); InputStream is = null; is = httpEntity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader( is, "UTF-8"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); String json = ""; json = sb.toString(); Log.d("JSON", "JSON is:" + json); and here is my php code to get the request: <?php echo $_POST['abc']; ?> When I run the application, the string json is nothing. I expect to get JSON is:abc2 Then I change the some code, in android part: HttpPost httpPost = new HttpPost(serverUrl); change to: HttpPost httpPost = new HttpPost(serverUrl + "?abc=abc3"); in php part: <?php echo $_GET['abc']; ?> This time, the string json in logcat is JSON is:abc3. It is correct!! I have tried lots of time, but seems cannot send HttpPost request with params. Any one can help me to find out what wrongs with my code??

  - by Er Rahul Rajkumar Gupta

  Can anyone please tell me that what is going on wrong with me in this code.Actually in following line of codes I am taking the path of sdcard in a string in jni (C code) and in concatenate function concatenating these manually using loop.The string returned by concatenate works fine but when I am converting it to jstring it prints garbage value in my logcat.

• What's wrong with this JAVA code for android?

  I have written this piece of code to break an image into 9 pieces and it gives me runtime error. There is no error in LogCat and I am stuck.

• Streaming Youtube Videos

  - by Vinay

  Hi All, I am writing an application to play the youtube videos using streaming. First method: I am getting the RTSP URL to the video using GData APIs. Here is the code to play the RTSP url. VideoView mVideoView = new VideoView(this); setContentView(mVideoView); mVideoView.setVideoURI(Uri.parse("rtsp://rtsp2.youtube.com/CiILENy73wIaGQkDwpjrUxOWQBMYESARFEgGUgZ2aWRlb3MM/0/0/0/video.3gp")); mVideoView.start(); But it throws error on both G1 device and emulator (Emulator has some firewall problem as per mailing list) Here is the error message ERROR/PlayerDriver(35): Command PLAYER_INIT completed with an error or info PVMFFailure Second method: A hack way to get the path of 3gp file from http://www.youtube.com/get_video?v=&t=<&<.. After getting the file path and I can call setVideoURI and it plays fine. But it is a hack way to achieve the requirement. I have checked the Youtube App also, it also does the hack way to play the youtube url.(Checked with logcat) I have tried changing from VideoView to MediaPlayer but no change in the error. Is there a "Clean" way to do this? Please let me know your thoughts.

• Created files on Archos 5 invisible on Windows Xp

  - by user352042

  I am fairly new to Android and this is my first post so I apologise in advance if I am breaking protocol or posting to the wrong board. Please feel free to move this post to somewhere more appropriate if required. I am developing for the 160 Gb Archos 5 Internet tablet. Not ideal as a development platform I know, but customer requirements mean we have no choice. It is running Android 1.6. I have updated the device firmware to the most recent available. Updating the version of Android is not an option at this point. Part of my app's requirement is to write information out to .txt files on the external storage directory so that these can be copied over the USB connection to a Windows XP PC using the Mobile media device (MTP) mode. I have followed all instructions I have come across carefully, eg I check that the storage is available using the technique described at http://developer.android.com/guide/topics/data/data-storage.html#filesExternal. However, althoug the files are created succesfully on the device (I can browse them and open them using the device's File Explorer - they are fine), when I connect the device to a Windows XP computer none of the directories or files I created appear and the size of their parent files suggest they do not exist. I have tried running over the ADB, checked logcat, tried a (signed) release version and even written a second test application which just creates a folder (this behaves the same, ie it creates the folder but this is not visible in Windows Explorer) - nothing anywhere gives me any suggestion as to what the problem might be. If anyone has heard of this before or has any ideas as to what else | could try to fix it please get in touch! We do not have any other devices to test on at the moment, although I hope to remedy this soon, customer permitting.

• Intent provided by Cursor is not fired correctly (LiveFolders)

  - by Felix

  In my desperation with trying to get LiveFolders working, I have tried the following in my LiveFolder ContentProvider: public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) { MatrixCursor mc = new MatrixCursor(new String[] { LiveFolders._ID, LiveFolders.NAME, LiveFolders.INTENT } ); Intent i = null; for (int j=0; j < 5; j++) { i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com/")); mc.addRow(new Object[] { j, "hello", i} ); } return mc; } Which, in all normalness, should launch the Browser and display the Google homepage when clicking on an item in the LiveFolder. But it doesn't. It gives a Application is not installed on your phone error. No, I'm not defining a base intent for my LiveFolder. logcat says: I/ActivityManager( 74): Starting activity: Intent { act=android.intent.action.VIEW dat=Intent { act=android.intent.action.VIEW dat=http://www.google.com/ } flg=0x10000000 } It seems it embeds the Intent I give it in the data section of the actually fired Intent. Why is it doing this? I'm really starting to believe it's a platform bug.

• Catch FileNotFoundException in AsyncTask method

  - by Musterknabe

  I'm getting the favicon of a website with a method. Of course not every website has a favicon. So I want to catch it. The app doesn't crash if the website doesn't have a favicon but I still get an FileNotFoundException in the LogCat. The problem I'm encountering is that I can't catch it When I add `catch (FileNotFoundException f) to my try-catch block it tells me Unreachable catch block for FileNotFoundException. This exception is never thrown from the try statement body. The options I have is to remove it or to add a throws declaration to the doInBackground-method. The latter is not possible. This is the whole Try-Catch try{ String baseURL = getBaseURL ( sourceURLArr[i] ); System.out.println(baseURL + "/favicon.ico"); Bitmap favicon = getBitmapFromURL( baseURL + "/favicon.ico"); Drawable fv = new BitmapDrawable(getResources(), Bitmap.createScaledBitmap(favicon, 20, 20, true)); source [i].setCompoundDrawablesWithIntrinsicBounds(fv, null, null, null); } catch(NullPointerException e){ } catch(FileNotFoundException f){ } I already tried to switch the FileNotFoundException with the NullPointerException but it was the same error. When I add the throws to the asynctask do in background method I get Exception FileNotFoundException is not compatible with throws clause in AsyncTask<Void,Void,Void>.doInBackground(Void[]) How can I now catch the FileNotFoundException?

• Approach for fixing NoClassDefFoundError?

  - by DJC

  I'm seeing this question is getting asked a lot in many different contexts. Perhaps we can set some strategies for locating and fixing it? I'm noobish myself so all I can contribute are horror stories and questions, sorry... It seems this is thrown when a class is visible at compile time but not at run time... how can this happen? In my case I am developing an app that uses the Google APIs, in Eclipse, for the Android platform. I've configured the Project Properties / Java Build Path / Libraries to include the gdata .jars and all is well. When I execute in the emulator I get a force close and the logcat shows a NoClassDefFoundError on a simple new ContactsService("myApp"); I've also tried a new CalendarService("myApp") with the same results. Is it possible or desirable to statically bind at compile time to avoid the problem? How could dynamic binding of an add-on library work in the mobile environment anyway? Either it has to be bound into my .apk or else I need to "install" it? ... hmmm. Advice much appreciated.

• Android: FragmentAdapter and pageview do not update the view

  - by user1240937

  My trouble is: when i get new data, my viewpager that use my custom adapter do not update view. I discovered that many programmer got same bug, so i tried a lot of suggestion but no way works for me. So tired. One more time, read my source and help me understand why i fail with updating view pleaseee! Here is my FragmentAdapter: private class SwipeyTabsPagerAdapter extends FragmentPagerAdapter implements SwipeyTabsAdapter { private final Context mContext; private String[] datas; public SwipeyTabsPagerAdapter(Context context, FragmentManager fm, String[] ds) { super(fm); this.mContext = context; datas=ds; } @Override public int getItemPosition(Object object) { return POSITION_NONE; } @Override public Fragment getItem(int position) { Log.e("new item:", datas[position]); return SwipeyTabFragment.newInstance(datas[position]); } @Override public int getCount() { return datas.length; } public TextView getTab(final int position, SwipeyTabs root) { TextView view = (TextView) LayoutInflater.from(mContext).inflate( R.layout.swipey_tab_indicator, root, false); view.setText(datas[position]); view.setOnClickListener(new OnClickListener() { public void onClick(View v) { mViewPager.setCurrentItem(position); } }); return view; } } and here is where i set adapter: SwipeyTabsPagerAdapter adapter = new SwipeyTabsPagerAdapter(getApplicationContext(), getSupportFragmentManager(),dicts); mViewPager.setAdapter(adapter); mTabs.setAdapter(adapter); mViewPager.getAdapter().notifyDataSetChanged(); By logcat, can see clearly that: only first time, newItem be processed, so view can not be update.

  I begin to use RESTful api of the Spring Framework in my android client application. But I have encountered with problems when I tried to execute HTTP request via postForObject/postForEntity methods. Here is my code: public String _URL = "https://noticemed.com/app/mobile/login"; public void BeginAuthorization(View view) { HttpHeaders requestHeaders = new HttpHeaders(); requestHeaders.setContentType(MediaType.APPLICATION_JSON); HttpEntity<String> _entity = new HttpEntity<String>(requestHeaders); RestTemplate templ = new RestTemplate(); templ.setRequestFactory(new HttpComponentsClientHttpRequestFactory()); templ.getMessageConverters().add(new MappingJacksonHttpMessageConverter()); ResponseEntity<String> _response = templ.postForEntity(_URL,_entity,String.class); //HERE APP CRASHES String _body = _response.getBody(); And here is a stack trace in logcat after app crashing. As you see there is no definite error message. So the question what am I doing wrong? How to fix this? May there is other way to do it?I really need a help. Thanks in advance!

• Accept All Cookies via HttpClient

  - by Vinay

  So this is currently how my app is set up: 1.) Login Activity. 2.) Once logged in, other activities may be fired up that use PHP scripts that require the cookies sent from logging in. I am using one HttpClient across my app to ensure that the same cookies are used, but my problem is that I am getting 2 of the 3 cookies rejected. I do not care about the validity of the cookies, but I do need them to be accepted. I tried setting the CookiePolicy, but that hasn't worked either. This is what logcat is saying: 11-26 10:33:57.613: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0] [name: cookie_user_id][value: 1][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" 11-26 10:33:57.593: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0][name: cookie_session_id][value: 1985208971][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" I am sure that my actual code is correct (my app still logs in correctly, just doesn't accept the aforementioned cookies), but here it is anyway: HttpGet httpget = new HttpGet(//MY URL); HttpResponse response; response = Main.httpclient.execute(httpget); HttpEntity entity = response.getEntity(); InputStream in = entity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuilder sb = new StringBuilder(); From here I use the StringBuilder to simply get the String of the response. Nothing fancy. I understand that the reason my cookies are being rejected is because of an "Illegal path attribute" (I am running a script at /mobile-api/login.php whereas the cookie will return with a path of just "/" for trackallthethings), but I would like to accept the cookies anyhow. Is there a way to do this?

• Android: How to put ListView in XML?

  - by FloIancu

  I want to make a simple app that shows a list of contacts (name, surname). My code: package lista.android; import java.util.*; import android.app.ListActivity; import android.os.Bundle; import android.widget.*; class Contact{ String nume; String prenume; Contact(String nume, String prenume){ this.nume=nume; this.prenume=prenume; } public String toString(){ return prenume +" "+ nume; } } public class Lista1Activity extends ListActivity { /** Called when the activity is first created. */ ArrayList <Contact> lista; ArrayAdapter <Contact> adaptor; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); setListAdapter(adaptor); lista=new ArrayList<Contact>(); adaptor=new ArrayAdapter<Contact>(this, R.id.element, lista); adaugaContact("Florian", "Iancu"); adaugaContact("Ioana", "Constantina"); } public void adaugaContact(String nume, String prenume){ lista.add(new Contact(nume, prenume)); adaptor.notifyDataSetChanged(); } } In the XML I have the LinearLayout and a TextView that is the list element. When I run it, the simulator says "Sorry, the application [...] has stopped unexpectedly. Please try again." The LogCat tells me I have to have a ListView whose id is android.R.id.lista. If I create a random ListView field in the XML file and give it the "lista" id, it still doesn't work. How to I call that ListView from XML to match something in my Java code? In other words, I know I'm wrong, but where and how do I fix it?

• Play Video From Raw Folder

  - by SterAllures

  Evening, I've just started programming with android and made a few programs and everything so I'm still kind of a novice but im trying to understand it all. So here's my problem, I'm trying to play a video, the thing is, I got it working when I Stream it from an URL with VideoView over the internet or when i place in on my sdcard. What I want to do now is play a video I've got in my res/raw folder, but it only plays audio and I don't understand why, it doesn't give any error in my logcat as far as I can see, also couldn't really find a solution with google since most of the answers are about VideoView and just put the video on your SDCard. Now someone told me I had to use setDisplay (SurfaceHolder) and I've also tried that but I still only get the audio. I hope somebody can help me to find a solution to this problem. VideoDemo.java package nl.melvin.videodemo; import android.app.Activity; import android.os.Bundle; import android.media.MediaPlayer; import android.view.SurfaceHolder; import android.view.SurfaceView; public class videodemo extends Activity { public SurfaceHolder holder; public SurfaceView surfaceView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); MediaPlayer mp = MediaPlayer.create(this, R.raw.mac); mp.setDisplay(holder); mp.start(); } } XML <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" > <SurfaceView android:id="@+id/surfaceview" android:layout_width="fill_parent" android:layout_height="fill_parent"> </SurfaceView>> </LinearLayout> I've also tried Uri.parse but it says it can't play the video (.mp4 format).

• Android lifecycle of thread-based game

  - by ehehhh

  I ran into a bit of trouble while trying to get my game to work correctly after being put to the background by the user or a phone call for example. My app has a SurfaceView class called GameView, which has the onDraw() method to do all the necessary drawing for my game and two threads - one for calling the onDraw() and one for doing the necessary calculations for the game's logic. I succesfully implemented onPause() and onResume(). (I paused both threads when back button was pressed and resumed them after user cancelled in the AlertDialog.) Now I would like to have the game paused the same way when onStop() gets called. I put both threads on pause and saved my characters location in the savedInstanceState, but when I start my app again, no method gets called (I checked with Logcat). I believe onRestart() should be called first, then onStart() and then onResume(), but none of that happens. What am I doing wrong? (Didn't include any code, because it seems to be a problem of me not understanding the lifecycle, not a problem in code. If it seems necessary, I'll post the parts you request.)

• Why am I getting a ClassCastException here?

  - by Holly

  I'm creating an android application and i'm trying to use a PreferenceActivity. I'm getting the java.lang.ClassCastException: java.lang.String error when it gets to this line return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_TERM, USER_TERM_DEF); I thought it might be because I'm not converting it properly from it's string value in the EditText box to the int I need but I can't figure out how to fix this, or is that even the cause? I'm flummoxed. Here's my preference activity class: public class UserPrefs extends PreferenceActivity { //option names and default vals private static final String USER_TERM = "term_length"; private static final String USER_YEAR = "year_length"; private static final int USER_TERM_DEF = 12; private static final int USER_YEAR_DEF = 34; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.preferences); } public static int getTermLength(Context context){ try{ return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_TERM, USER_TERM_DEF); }catch (ClassCastException e){Log.v("getTermLength", "error::: " + e); } //return 1;//temporary, needed to catch the error and couldn't without adding a return outside the block.// } public static int getYearLength(Context context){ return PreferenceManager.getDefaultSharedPreferences(context).getInt(USER_YEAR, USER_YEAR_DEF); } And here's the bit of code where I'm trying to use the the preferences inside another class: public float alterForFrequency(Context keypadContext, float enteredAmount, String spinnerPosition){ int termLength = UserPrefs.getTermLength(keypadContext); int yearLength = UserPrefs.getYearLength(keypadContext); } The complete android logcat, i've uploaded here: http://freetexthost.com/v3t4ta3wbi

• "No keyboard for id 0"?

  - by Mellon

  I am new in Android app. development, now I have encountered a strange problem with the Menu button. Here is the thing: I have two activities, "ActivityOne" and "ActivityTwo", where "ActivityTwo" is the child Activity of "ActivityOne". In both activity, I have defined the menu button options like following: @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuItem insertMenuItem = menu.add(0, INSERT_ID, 0, R.string.menu_insert); insertMenuItem.setIcon(R.drawable.ic_menu_add); MenuItem settingMenuItem = menu.add(0, SETTING_ID, 0, R.string.menu_setting); settingMenuItem.setIcon(R.drawable.ic_menu_settings); MenuItem aboutMenuItem = menu.add(0, ABOUT_ID, 0, R.string.menu_about); aboutMenuItem.setIcon(R.drawable.ic_menu_about); logPrinter.println("creating menu options..."); return true; } @Override public boolean onMenuItemSelected(int featureId, MenuItem item) { switch(item.getItemId()) { case INSERT_ID: doInsert(); return true; case SETTING_ID: return true; case ABOUT_ID: showAbout(); return true; } return super.onMenuItemSelected(featureId, item); } In "ActivityOne", when I click the physical Menu button, there is no menu options pop up from screen bottom, when I checked the LogCat console, there are two warning messages, which are "No keyboard for id 0" and "Using default keyMap:/system/usr/keychars/qwerty.kcm.bin" . BUT, in "ActivityTwo", the menu button works fine, it shows me those menu options I defined. Why the menu button does not work in "ActivityOne" ?? What does the warning msg mean???

• Battery drains even with app off screen, could it be Location Services doing it?

  - by John Jorsett

  I run my app, which uses GPS and Bluetooth, then hit the back button so it goes off screen. I verified via LogCat that the app's onDestroy was called. OnDestroy removes the location listeners and shuts down my app's Bluetooth service. I look at the phone 8 hours later and half the battery charge has been consumed, and my app was responsible according the phone's Battery Use screen. If I use the phone's Settings menu to Force Stop the app, this doesn't occur. So my question is: do I need to do something more than remove the listeners to stop Location Services from consuming power? That's the only thing I can think of that would be draining the battery to that degree when the app is supposedly dormant. Here's my onStart() where I turn on the location-related stuff and Bluetooth: @Override public void onStart() { super.onStart(); if(D_GEN) Log.d(TAG, "MainActivity onStart, adding location listeners"); // If BT is not on, request that it be enabled. // setupBluetooth() will then be called during onActivityResult if (!mBluetoothAdapter.isEnabled()) { Intent enableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); startActivityForResult(enableIntent, REQUEST_ENABLE_BT); // Otherwise, setup the Bluetooth session } else { if (mBluetoothService == null) setupBluetooth(); } // Define listeners that respond to location updates mLocationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, GPS_UPDATE_INTERVAL, 0, this); mLocationManager.addGpsStatusListener(this); mLocationManager.addNmeaListener(this); } And here's my onDestroy() where I remove them: public void onDestroy() { super.onDestroy(); if(D_GEN) Log.d(TAG, "MainActivity onDestroy, removing update listeners"); // Remove the location updates if(mLocationManager != null) { mLocationManager.removeUpdates(this); mLocationManager.removeGpsStatusListener(this); mLocationManager.removeNmeaListener(this); } if(D_GEN) Log.d(TAG, "MainActivity onDestroy, finished removing update listeners"); if(D_GEN) Log.d(TAG, "MainActivity onDestroy, stopping Bluetooth"); stopBluetooth(); if(D_GEN) Log.d(TAG, "MainActivity onDestroy finished"); }
