• Android: Strange out of memory issue

  - by Chrispix

  I am not sure where to start to explain this one. I have a list view with a couple image buttons on each row. When you click the list row, it launches a new activity. If you review some of my other posts, I have had to build my own tabs because of an issue w/ the camera layout. The activity that gets launched for result is a map. If I click on my button to launch the image preview (load an image off the sd card) the application returns from the activity back to the listview activity to the result handler to relaunch my new activity which is nothing more than an image widget. So here is the issue, the image preview on the list view is being done w/ the cursor & listadapter. This makes it pretty simple, but I am not sure how I can put a resized (i.e. smaller bit size not pixel) image as the src for the imgbutton on the fly. So I just resized the image that came off the phone camera. The issue is that I get an out of memory error when it tries to go back and re-launch the 2nd activity. ** My question : is there a way I can build the list adapter easily row by row, where I can resize on the fly (bit wise)? - this would be preferable as I also need to make some changes to the properties of the widgets/elements in each row as I am unable to select a row w/ touch screen b/c of focus issue. (I can use roller ball). ** I know I can do an out of band resize and save of my image, but that is not really what I want to do, but some sample code for that would be nice if that is your suggestion. As soon as I disabled the image on the listview it worked fine again. FYI : This is how I was doing it : String[] from = new String[] { DBHelper.KEY_BUSINESSNAME, DBHelper.KEY_ADDRESS, DBHelper.KEY_CITY, DBHelper.KEY_GPSLONG, DBHelper.KEY_GPSLAT, DBHelper.KEY_IMAGEFILENAME + ""}; to = new int[] { R.id.businessname, R.id.address, R.id.city, R.id.gpslong, R.id.gpslat, R.id.imagefilename }; notes = new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to); setListAdapter(notes); Where R.id.imagefilename is a ButtonImage Here is my LogCat 01-25 05:05:49.877: ERROR/dalvikvm-heap(3896): 6291456-byte external allocation too

• CastClassException on Custom View

  - by tuxGurl

  When I try to findViewById() on my custom view I keep getting a ClassCastException. I've tried so many things that I'm sure I've botched the code now! To make sure I'm not going insane I stripped down the classes to their bare minimum inorder to find what was wrong. I'm new to android programming and I'm sure I'm missing something basic. This is BaseImageView an extended view class. package com.company.product.client.android.gui.views; import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.view.View; public class BaseImageView extends View { public BaseImageView(Context context) { super(context); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); canvas.drawColor(Color.GREEN); } } This is LiveImageView an extension of the BaseImageView class. package com.company.product.client.android.gui.views; import android.content.Context; import android.util.AttributeSet; public class LiveImageView extends BaseImageView { public LiveImageView(Context context, AttributeSet attrs) { super(context); } } Here is the Layout my_view.xml. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center"> <View class="com.company.product.client.android.gui.views.LiveImageView" android:id="@+id/lvImage" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> And here is the onCreate in my Activity LiveViewActivity. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { setContentView(R.layout.my_view); final LiveImageView lvImage = (LiveImageView) findViewById(R.id.lvImage); } catch (final Exception e) { Log.e(TAG, "onCreate() Exception: " + e.toString()); e.printStackTrace(); } Finally, this is stack trace. 02-11 17:25:24.829: ERROR/LiveViewActivity(1942): onCreate() Exception: java.lang.ClassCastException: android.view.View 02-11 17:25:24.839: WARN/System.err(1942): java.lang.ClassCastException: android.view.View 02-11 17:25:24.839: WARN/System.err(1942): at com.company.product.client.android.gui.screen.LiveViewActivity.onCreate(LiveViewActivity.java:26) 02-11 17:25:24.839: WARN/System.err(1942): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2459) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2512) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread.access$2200(ActivityThread.java:119) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1863) 02-11 17:25:24.859: WARN/System.err(1942): at android.os.Handler.dispatchMessage(Handler.java:99) 02-11 17:25:24.859: WARN/System.err(1942): at android.os.Looper.loop(Looper.java:123) 02-11 17:25:24.859: WARN/System.err(1942): at android.app.ActivityThread.main(ActivityThread.java:4363) 02-11 17:25:24.869: WARN/System.err(1942): at java.lang.reflect.Method.invokeNative(Native Method) 02-11 17:25:24.869: WARN/System.err(1942): at java.lang.reflect.Method.invoke(Method.java:521) 02-11 17:25:24.869: WARN/System.err(1942): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 02-11 17:25:24.869: WARN/System.err(1942): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 02-11 17:25:24.879: WARN/System.err(1942): at dalvik.system.NativeStart.main(Native Method)

• RadioGroup onCheckedChanged function won't fire

  - by user1758088

  First time/long time. My app keeps track of restaurant servers' shift sales to help them budget. In the activity that displays past shifts, I've created a RadioGroup under the ListView so the server can choose lunch, dinner, or both. I've implemented RadioGroup.onCheckedChangeListener, but onCheckChanged never gets called. I also tried an anonymous inner class as listener, same result. I tried to copy/modify code from this answer: http://stackoverflow.com/a/9595528 ...but when I added the @Override to the callback function, the Eclipse compiler gave me an error (not warning) that the method must override a superclass, and the quick fix was to remove the override. I'm pretty sure the signatures are correct, as they were made with Eclipse's autocomplete and implement methods facilities. I then followed instructions to move my java compiler from 1.5 to 1.6, and none of the above listed behavior seemed to change. Here's the code I thing is relavent: public class DataActivity extends ListActivity implements OnCheckedChangeListener{ RadioButton rbBoth; RadioButton rbDinnerOnly; RadioButton rbLunchOnly; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.database); ... final RadioGroup rgGroup = (RadioGroup)findViewById(R.id.DataRadioGroup); rbBoth = (RadioButton)findViewById(R.id.RadioBoth); rbDinnerOnly = (RadioButton)findViewById(R.id.RadioDinnerOnly); rbLunchOnly = (RadioButton)findViewById(R.id.RadioLunchOnly); rgGroup.setOnCheckedChangeListener(this); populateAllShifts(); } ... public void onCheckedChanged(RadioGroup group, int checkedId) { rbLunchOnly.setText("Click!"); Toast.makeText(getApplicationContext(), "Lunch Only", Toast.LENGTH_LONG).show(); if(group.getCheckedRadioButtonId() == R.id.RadioBoth){ populateAllShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioLunchOnly){ populatLunchShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioDinnerOnly){ populateDinnerShifts(); return; } } There is a ListView in this class with a custom adapter, but if my understanding and my XML are correct, the RadioGroup should be outside of the list: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/llDataLayout" android:weightSum="5" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <ListView android:layout_weight="4" android:layout_width="fill_parent" android:id="@android:id/list" android:layout_height="wrap_content"></ListView> <RadioGroup android:layout_weight="1" android:id="@+id/DataRadioGroup" android:orientation="horizontal" android:layout_height="wrap_content" android:layout_width="fill_parent"> <RadioButton android:text="Lunch and Dinner" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioBoth"/> <RadioButton android:text="Dinner Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioDinnerOnly"/> <RadioButton android:text="Lunch Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioLunchOnly"/> </RadioGroup> </LinearLayout> Any ideas out there?

• Android popup style activity which sits on top of any other apps

  - by RenegadeAndy

  What I want to create is a popup style application. I have a service in the background - something arrives on the queue and i want an activity to start to inform the user - very very similar to the functionality of SMSPopup app. So I have the code where something arrives on the queue and it calls my activity. However for some reason the activity always shows on top of the originally started activity instead of just appearing on the main desktop of the android device. As an example: I have the main activity which is shown when the application is run I have the service which checks queue I have a popup activity. When i start the main activity it starts the service - I can now close this. I then have something on the queue and it creates the popup activity which launches the main activity with the popup on top of it :S How do I stop this and have it behave as i want... The popup class is : package com.andy.tabletsms.work; import com.andy.tabletsms.tablet.R; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.view.Gravity; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.Button; import android.widget.PopupWindow; import android.widget.TextView; import android.widget.Toast; public class SMSPopup extends Activity implements OnClickListener{ public static String msg; @Override public void onCreate(Bundle bundle){ super.onCreate(bundle); // Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG).show(); this.setContentView(R.layout.popup); TextView tv = (TextView)findViewById(R.id.txtLbl); Intent intent = getIntent(); if (intent != null){ Bundle bb = intent.getExtras(); if (bb != null){ msg = bb.getString("com.andy.tabletsms.message"); } } if(msg == null){ msg = "LOLOLOL"; } tv.setText(msg); Button b = (Button)findViewById(R.id.closeBtn); b.setOnClickListener(this); } @Override public void onClick(View v) { this.finish(); } } and I call the activity from a broadcast receiver which checks the queue every 30 seconds or so : if(main.msgs.size()0){ Intent testActivityIntent = new Intent(context.getApplicationContext(), com.andy.tabletsms.work.SMSPopup.class); testActivityIntent.putExtra("com.andy.tabletsms.message", main.msgs.get(0)); testActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(testActivityIntent); } The layout is here : http://pastebin.com/F25u6wdM

Or do I have to imitate it in my own layout?

• Emulate disk IO speeds in Android SDK

  - by Ben L.

  I don't have a physical Android device to work with, so all I can use is the emulator. I'm wondering if there's something I could use to make the IO speeds more realistic - How do I slow down disk access to the speed it would be on a physical device? Also, this may be unrelated, but when I change the speed and latency options in Eclipse ADT DDMS view, I don't notice any change in internet speed on the emulator. Is this a bug?

• HelloWebView Sample: now using SDK 3 and getting killed

  - by Tim

  Hey Folks, Well I was trying to get the HelloWebview example working with SDK 7 with no success (see HelloWebView Sample: java.lang.SecurityException: Permission Denial thread), so I decided just out of curiosity to back off to SDK3 to see if I could learn anything. I have been able to get all the "Layout" samples to work and decided to try something a little harder. Unfortunately, I still cannot get the simple HelloWebView app to run. I no longer get a Permission Denial but now the app is getting killed. Killed usually implies that there are not enough resources (memory etc.) for an application to run.... Any thoughts? Are there any other log files I can look at either on my computer or on the emulator? The main.xml, manifest, and console output are below. Let me know if you need more information.

• Spinner activity not working

  - by user1696863

  I'm trying to create an activity, RateCardActivity, which has a spinner in it. My layout file for RateCardActivity is rate_card. My RateCardActivity looks like the following. public class RateCardActivity { public void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.rate_card); Spinner spinner = (Spinner) findViewById(R.id.select_city); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.select_city, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); } } The layout file rate_card is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:custom="http://schemas.android.com/apk/res/com.olacabs.customer" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@android:color/darker_gray" android:gravity="center" android:paddingBottom="4dp" android:paddingTop="4dp" android:text="@string/rate_card" android:textColor="@color/white" android:textSize="20dp" custom:customFont="litera_bold.ttf" /> <Spinner android:id="@+id/select_city" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> The RateCardActivity is called from another activity using an intent (I'm sure there is nothing wrong with that part of the code as when I substitute RateCardActivity with another activity, the application works fine). When I try to open the RateCardActivity in the application in emulator, the application crashes and I got the message "The application has stopped unexpectedly. Please try again later." I can't seem to understand what I'm doing wrong, and want to know how to correct this?

• multiple screen support

  - by pedr0

  Hi at all, I have some problem with multiple screen support, I work with dp(dpi) for specify the layout_heigth and layout_width and I hope that is the better way to support multiple screen, but when I tried with two smartphone I meet two different result. I give an example, this is a layout I use: <?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/cities_main_layout" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView android:id="@+id/citieslist" android:layout_width="wrap_content" android:layout_height="320dip" android:layout_gravity="center_vertical" android:layout_below="@id/cities_main_layout" /> <LinearLayout android:id="@+id/cities_button_layout" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/citieslist" android:layout_gravity="center_vertical"> <Button android:id="@+id/bycountry" android:layout_height="50dip" android:layout_width="105dip" android:background="@drawable/buttonmarket" android:text="@string/button_bycountry" /> <Button android:id="@+id/top10" android:layout_height="50dip" android:layout_width="105dip" android:background="@drawable/buttonmarket" android:text="@string/button_top10" /> <Button android:id="@+id/recommended" android:layout_height="50dip" android:layout_width="105dip" android:background="@drawable/buttonmarket" android:text="@string/button_recommended" /> </LinearLayout> </RelativeLayout> The button are at the bottom of the layout, and I see two different result: In the last smartphone I can see the buttons, instead in the first I cannot...what's wrong? I have to write a layout for any set of screen??!!!

• How to programmatically disable onClick handler on Android AppWidget Button

  - by Gaks

  I have a Button on appwidget, that I need to 'enable'/'disable' programmatically from a Service. First idea was to call setBoolean(R.id.buttonid, "setClickable", false) to disable it, but apparently you can't call setClickable remotely. Another idea was was remove the text label from it with rv.setTextViewText(R.id.buttonid, "") and then remove the click handler by rv.setOnClickPendingIntent(R.id.buttonid, null). Unfortunately passing null to it causes NullPointerException in in android.app.ActivityThread.handleServiceArgs Is there some other way to programmatically disable/enable appwidget Button? I could just call rv.setViewVisibility(R.id.buttonid, View.GONE) to hide the button completely instead of disabling it. This would however completely break whole widget layout and I would like to avoid it. The solution I'm using now is hiding the button with setViewVisibility and showing other blank button instead to the keep appwidget layout as it was before.

• Android getWifiState to String

  - by ahsteele

  I am attempting to get the string representation of an Android device's current WiFi state. I am using the getWifiState() method of the WiFiManager and am getting an integer returned depending on the current state. This makes total sense as getWifiState() is supposed to return an integer. The method's documentation indicates that the possible return values translate to one of the following constant values 0 WIFI_STATE_DISABLING 1 WIFI_STATE_DISABLED 2 WIFI_STATE_ENABLING 3 WIFI_STATE_ENABLED 4 WIFI_STATE_UNKNOWN Is there an easy way to translate the integer returned from getWiFiState() to a string representation? I've looked at getIntExtra but am unsure of its use.

• Find package name for Android apps to use Intent to launch Market app from web

  - by eom

  I'm creating a mobile website that will include a page from which people can download relevant apps that we recommend. I've found instructions for creating the links to launch the Market but this assumes that you are the developer of the app in question and know the exact package name. Is there any way to get the package name, other than just contacting the developers and asking? Also, it turns out that those instructions don't really work for creating web hyperlinks. They only give you a URI to reference in a string of Java code in another Android app. Our site is in Drupal, so Java is not going to work. For the iPhone, I found easy instructions for getting the URL/link style I need from the iTunes store, so I'm looking for info like that.

• Storing Tables of Information on the Android Platform.

  - by Tarmon

  I have about twenty pages of information that is stored in tables that needs to be stored in my Android application. Each column is a designated stop on a bus route and the column is filled with times that the bus will be at the stop. There is also certain information that needs to be associated with some times, such as if the bus is handicap accessible at a certain time. Here is an example of one of the tables: Bus Times I have thought about using a SQL lite as that seems as though it would be able to store these tables quite easily; but when I think of using SQL I think of dynamic data storage and this shouldn't be changing more than once a year. Is SQL appropriate for this application? Is there a better way to do this? Thanks, Rob

  - by robs

  Hello everyone, i'm new to android development and i'm playing around with json data. I managed to get the parsing to work. I want to show a ProgressDialog and i read that i need to use AsyncTask that. But for some reason i get a force close as soon as i put the same working code inside doInBackground() eventhough eclipse says everything is fine. Here is the source code: public class HomeActivity extends Activity { public class BackgroundAsyncTask extends AsyncTask<Void, Integer, Void> { ProgressDialog dialog = new ProgressDialog

onPostExecute() { dialog.dismiss(); } @Override protected Void doInBackground(Void... params) { try { URL json = new URL("http://www.corps-marchia.de/jsontest.php"); URLConnection tc = json.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader(tc.getInputStream())); String line; while ((line = in.readLine()) != null) { JSONArray ja = new JSONArray(line); JSONObject jo = (JSONObject) ja.get(0); TextView txtView = (TextView)findViewById(R.id.TextView01); txtView.setText(jo.getString("text")); } } catch (MalformedURLException e) { e.printStackTrace(); }

• Panel widget overlapping other contents in android

  - by walker

  I'm trying to utilize the Panel widget introduced in android-misc-widgets. It's been good so far. Now the problem is the sliding panel overlaps my top menu bar. For clarification look at the following screenshots. This is when I open panel using drag gesture (no problem here): This is when I open the panel with a single tap (look at the icons overlapping the top menu): There is one other problem, If there is any content inside the activity, opening the panel pushes that content out of the screen!
