• Android: How do I make a video splash screen repeat until webview finishes loading the url?

  - by Nikoli4

  I would like to make a small video (about 4 seconds) repeat until webview finishes loading the desired URL in the background. Right now the video plays once, then a blank black screen comes up until the page loads. I'm still pretty new to this... Thanks in advance for any help! Sorry for the EDITED stuff, but it was necessary. Here is my splash java import android.app.Activity; import android.content.Intent; import android.media.MediaPlayer; import android.media.MediaPlayer.OnCompletionListener; import android.os.Bundle; import android.widget.VideoView; public class Splash extends Activity implements OnCompletionListener { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.splash); VideoView video = (VideoView) findViewById(R.id.videoView); video.setVideoPath("android.resource://com.EDITED/raw/" + R.raw.splash); video.start(); video.setOnCompletionListener(this); } @Override public void onCompletion(MediaPlayer mp) { Intent intent = new Intent(this, EDITEDWebActivity.class); startActivity(intent); finish(); } }

• Fragment method and socket.io

  - by Tolgay Toklar

  I have a method,this method updates an array list in fragment.I can call this method in main activity like this public void getFromUser(String message) { addMessageToFragment("ok"); } public void addMessageToFragment(String message) { Log.w("Step 1",message); frgObj.addMessageToList("asd"); } getFromUser is calling from fragment(when user presses the button) this is working as well.But I am using socket.io in my app,when I try to call this method from socket.io,app is not working. public void on(String event, IOAcknowledge ack, Object... args) { try{ addMessageToFragment("ok"); } catch (JSONException e) {} } When this callback function calls,app is giving this errors: 08-19 11:57:24.813: W/System.err(4962): io.socket.SocketIOException: Exception was thrown in on(String, JSONObject[]). 08-19 11:57:24.813: W/System.err(4962): Message was: 5:::{"name":"listele","args":[{"mesaj":"123","gonderen":"781722165-tolgay007-DKSMIcIYGahPuKXriM83","alici":"tolgay007","blck_id":"781722165-tolgay007","out_username":"Anony-781722","ars_status":1,"longinf":"3aqghef","a_status":1}]} 08-19 11:57:24.813: W/System.err(4962): at io.socket.IOConnection.transportMessage(IOConnection.java:702) 08-19 11:57:24.813: W/System.err(4962): at io.socket.WebsocketTransport.onMessage(WebsocketTransport.java:82) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.client.WebSocketClient.onWebsocketMessage(WebSocketClient.java:361) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.WebSocketImpl.deliverMessage(WebSocketImpl.java:565) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.WebSocketImpl.decodeFrames(WebSocketImpl.java:331) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.WebSocketImpl.decode(WebSocketImpl.java:152) 08-19 11:57:24.813: W/System.err(4962): at org.java_websocket.client.WebSocketClient.interruptableRun(WebSocketClient.java:247) 08-19 11:57:24.823: W/System.err(4962): at org.java_websocket.client.WebSocketClient.run(WebSocketClient.java:193) 08-19 11:57:24.823: W/System.err(4962): at java.lang.Thread.run(Thread.java:841) 08-19 11:57:24.823: W/System.err(4962): Caused by: android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewRootImpl.checkThread(ViewRootImpl.java:6094) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewRootImpl.focusableViewAvailable(ViewRootImpl.java:2800) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.ViewGroup.focusableViewAvailable(ViewGroup.java:650) 08-19 11:57:24.823: W/System.err(4962): at android.view.View.setFlags(View.java:8878) 08-19 11:57:24.823: W/System.err(4962): at android.view.View.setFocusableInTouchMode(View.java:6114) 08-19 11:57:24.823: W/System.err(4962): at android.widget.AdapterView.checkFocus(AdapterView.java:718) 08-19 11:57:24.823: W/System.err(4962): at android.widget.AdapterView$AdapterDataSetObserver.onChanged(AdapterView.java:813) 08-19 11:57:24.823: W/System.err(4962): at android.widget.AbsListView$AdapterDataSetObserver.onChanged(AbsListView.java:6280) 08-19 11:57:24.823: W/System.err(4962): at android.database.DataSetObservable.notifyChanged(DataSetObservable.java:37) 08-19 11:57:24.823: W/System.err(4962): at android.widget.BaseAdapter.notifyDataSetChanged(BaseAdapter.java:50) 08-19 11:57:24.823: W/System.err(4962): at android.widget.ArrayAdapter.notifyDataSetChanged(ArrayAdapter.java:286) 08-19 11:57:24.823: W/System.err(4962): at com.impact.ribony.ConversationFragment.addMessageToList(ConversationFragment.java:91) 08-19 11:57:24.823: W/System.err(4962): at com.impact.ribony.MainActivity.addMessageToFragment(MainActivity.java:344) 08-19 11:57:24.823: W/System.err(4962): at com.impact.ribony.MainActivity$2.on(MainActivity.java:183) 08-19 11:57:24.823: W/System.err(4962): at io.socket.IOConnection.on(IOConnection.java:908) 08-19 11:57:24.883: W/System.err(4962): at io.socket.IOConnection.transportMessage(IOConnection.java:697) I didn't understand this error.What can be cause this error ?

• how to debug "deep" crashes in Android?

  - by eerok512

  Hi All, I've been trying to debug an android crash that is occurring without a Java Stack Trace... Java Stack Trace bugs are very easy for me to fix... but this bug I'm getting seems to be crashing inside the "NDK" or whatever it is the deep internals of Android are called... I've made no modifications to the NDK btw... I just dunno what else to call that layer hehe. Anyway I'm mainly looking for advice on deep-debug methods, rather than help with this specific problem... because I doubt I can post all the source code involved... so really I just need to know how to set breakpoints at the deep layers or whatever other methods there are to trace deep-crashes to their source... so I will briefly describe the bug and then post a LogCat. I have an app with 7 Activities Activity_INTRO Activity_EULA Activity_MAIN Activity_Contact Activity_News Activity_Library Activity_More INTRO is the initiating one... it fades in some company logos... after displaying them for a set time it jumps to the EULA activity... after the user accepts the EULA, it jumps to MAIN... MAIN then creates a TabHost and populates it with the 4 remaining activities now heres the thing... when I click on say, the More tab of the TabHost, the app pauses for a few seconds and then hard-crashes... no java stack trace, but an actual ASM level trace with the registers and IP and stack... the same thing occurs no matter which tab I select, Contact, News, Library, More... all of them crash with the same hard-crash if however I set the manifest to start the app at Activity_MAIN, bypassing the INTRO and EULA, then these crashes do not occur... so something is lingering from those opening activities that is somehow hosing the TabHost'ed Activities... and I'm wondering what the hell that could be... because I'm using finish() on those activites when they need to jump... in fact here is how I'm doing it let me know if you see any bugs: when jumping from INTRO to EULA I do: //Display the EULA Intent newIntent = new Intent (avi, Activity_EULA.class); startActivity (newIntent); finish(); and EULA to MAIN: Intent newIntent = new Intent (this, Activity_Main.class); startActivity (newIntent); finish(); anyway, here is the hard crash log... please let me know if there is some way I can reverse engineer either /system/lib/libcutils.so or /system/lib/libandroid_runtime.so, because I think the crash is happening in one of them... i think its happening in the libandroid_runtime in fact.... anyway on to the log: 12-25 00:56:07.322: INFO/DEBUG(551): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** 12-25 00:56:07.332: INFO/DEBUG(551): Build fingerprint: 'generic/sdk/generic/:1.5/CUPCAKE/150240:eng/test-keys' 12-25 00:56:07.362: INFO/DEBUG(551): pid: 722, tid: 723 >>> com.killerapps.chokes <<< 12-25 00:56:07.362: INFO/DEBUG(551): signal 11 (SIGSEGV), fault addr 00000004 12-25 00:56:07.362: INFO/DEBUG(551): r0 00000004 r1 40021800 r2 00000004 r3 ad3296c5 12-25 00:56:07.372: INFO/DEBUG(551): r4 00000000 r5 00000000 r6 ad342da5 r7 41039fb8 12-25 00:56:07.372: INFO/DEBUG(551): r8 100ffcb0 r9 41039fb0 10 41e014a0 fp 00001071 12-25 00:56:07.382: INFO/DEBUG(551): ip ad35b874 sp 100ffc98 lr ad3296cf pc afb045a8 cpsr 00000010 12-25 00:56:07.552: INFO/DEBUG(551): #00 pc 000045a8 /system/lib/libcutils.so 12-25 00:56:07.572: INFO/DEBUG(551): #01 lr ad3296cf /system/lib/libandroid_runtime.so 12-25 00:56:07.582: INFO/DEBUG(551): stack: 12-25 00:56:07.582: INFO/DEBUG(551): 100ffc58 00000000 12-25 00:56:07.592: INFO/DEBUG(551): 100ffc5c 001c5278 [heap] 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc60 000000da 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc64 0016c778 [heap] 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc68 100ffcc8 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc6c 001c5278 [heap] 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc70 427d1ac0 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc74 000000c1 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc78 40021800 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc7c 000000c2 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc80 00000000 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc84 00000000 12-25 00:56:07.622: INFO/DEBUG(551): 100ffc88 00000000 12-25 00:56:07.622: INFO/DEBUG(551): 100ffc8c 00000000 12-25 00:56:07.622: INFO/DEBUG(551): 100ffc90 df002777 12-25 00:56:07.632: INFO/DEBUG(551): 100ffc94 e3a070ad 12-25 00:56:07.632: INFO/DEBUG(551): #00 100ffc98 00000000 12-25 00:56:07.632: INFO/DEBUG(551): 100ffc9c ad3296cf /system/lib/libandroid_runtime.so 12-25 00:56:07.632: INFO/DEBUG(551): 100ffca0 100ffcd0 12-25 00:56:07.642: INFO/DEBUG(551): 100ffca4 ad342db5 /system/lib/libandroid_runtime.so 12-25 00:56:07.642: INFO/DEBUG(551): 100ffca8 410a79d0 12-25 00:56:07.642: INFO/DEBUG(551): 100ffcac ad00e3b8 /system/lib/libdvm.so 12-25 00:56:07.652: INFO/DEBUG(551): 100ffcb0 410a79d0 12-25 00:56:07.652: INFO/DEBUG(551): 100ffcb4 0016bac0 [heap] 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcb8 ad342da5 /system/lib/libandroid_runtime.so 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcbc 40021800 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcc0 410a79d0 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcc4 afe39dd0 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcc8 100ffcd0 12-25 00:56:07.662: INFO/DEBUG(551): 100ffccc ad040a8d /system/lib/libdvm.so 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcd0 41039fb0 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcd4 420000f8 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcd8 ad342da5 /system/lib/libandroid_runtime.so 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcdc 100ffd48 12-25 00:56:07.852: DEBUG/dalvikvm(722): GC freed 367 objects / 15144 bytes in 210ms 12-25 00:56:08.081: DEBUG/InetAddress(722): www.akillerapp.com: 74.86.47.202 (family 2, proto 6) 12-25 00:56:08.242: DEBUG/dalvikvm(722): GC freed 62 objects / 2328 bytes in 122ms 12-25 00:56:08.771: DEBUG/dalvikvm(722): GC freed 245 objects / 11744 bytes in 179ms 12-25 00:56:09.131: INFO/ActivityManager(577): Process com.killerapps.chokes (pid 722) has died. 12-25 00:56:09.171: INFO/WindowManager(577): WIN DEATH: Window{43719320 com.killerapps.chokes/com.killerapps.chokes.Activity_Main paused=false} 12-25 00:56:09.251: INFO/DEBUG(551): debuggerd committing suicide to free the zombie! 12-25 00:56:09.291: DEBUG/Zygote(553): Process 722 terminated by signal (11) 12-25 00:56:09.311: INFO/DEBUG(781): debuggerd: Jun 30 2009 17:00:51 12-25 00:56:09.331: WARN/InputManagerService(577): Got RemoteException sending setActive(false) notification to pid 722 uid 10020

• Android - making a layout like Entourage/Outlook calendar

  - by teepusink

  Hi, I'm trying to build a layout / view like the Entourage/Outlook calendar view, where when I schedule a time block, a new view will popup overlaying the time block. Something like this one except it's daily and not monthly like in the image http://images.appleinsider.com/office-2008-entourage-10.png What is the best way to implement that? Right now I'm using TableLayout to create the time on the 1st column and supposedly overlay to schedule made on the 2nd column. However, things got very messy especially when the minutes go to 15 minutes and there are overlapping schdule. Wonder if using other layout might work better? Thanks, Tee

• Force File Reload Before Build

  - by Byron Ross

  We have a tool that generates some code (.cs) files that are used to build the project. The tool is run during the pre-build step, but the files are updated in the solution only after the build, which means the build needs to be performed twice to clear the errors after a change to the input. Example: Modify Tool Input File Run Build Tool Runs and changes source file Build Fails Run Build Tool Runs and changes source file (but it doesn's actually change, because the input remains the same) Build Succeeds Any ideas how we can do away with the double build, and still let our tool be run from VS? Thanks guys!

• Importing war file into eclipse and build path problem

  - by Todd

  Hi, I am facing some weird problem when importing .war file into eclipse. The problem is, the build folder does not contain any necessary class folder. So when I try to set the build path, eclipse reports "Error while adding to build path. Reason: cannot nest output folder 'projectName/build/class' inside 'projectName/build'. From what I understand, 'build' folder is what classes get collected(as build version) right? I tried to ignore build path and just export .war file into tomcat server, but somehow servlet file keeps showing old code, which I changed in eclipse. So, I am thinking without proper build folder, exported .war will not contain modified servlect code.( I am sorry if this doesn't sound clear) What can I do to fix this problem? I already tried to create a whole new workspace and restarted eclipse several times and it didn't solve the problem.

  Hi Hi I'm trying to build a layout where some shapes will popup every 2 seconds. If the user will click one of these shapes, they have to disappear. What is the correct way of doing this? I thought about a thread, but i missed out. Here's my code at the moment (is not working): public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); l = new LinearLayout(this); setContentView(l); int counter = 1; View v = new CustomDrawableView(this,20,50); l.addView(v); Thread t = new Thread() { public void run() { while (true) { Log.i("THREAD","INSIDE"); View h = new CustomDrawableView(c, (int)Math.round(Math.random()*100), (int)Math.round(Math.random()*100)); SystemClock.sleep(2000); l.addView(h); } } }; t.start(); }

• Can FLV AAC stream be played in Android

  - by HariKJ

  Hi, I'm trying to build a radio player and the client is providing a stream which is a FLV container with the audio being AAC When I read the headers it shows up as audio/aacp. I have tried all possible ways such as using the 1) Streaming through mediaplayer (Does not work) 2) Use the NPR mode of using a proxy stream (I get a broken pipe exception) 3) Play it in chunks ( Plays but I need the SDCard and the playback is not very great) 4) Use the GPL'd FAAD2 Library but I would have to pay the royalty fee Can some one help me out on figuring this issue out. The last option that I have is to have my client change the stream to mp3 container (which I know that it works) Regards, Hari

  I a have a notification in a receiver that fires off fine, but it restarts the activity (thus clearing the edittexts and resetting the toggle button) How can i set it so that when its tapped on it resumes the activity rather that clearing and resetting everything? My current code doesnt work. Current Code String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date()); Intent intenti= new Intent(context, Locator.class); intenti.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intenti, 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context) .setSmallIcon(R.drawable.xxxxxxnotifyicon) .setContentTitle("xxxxxxx Link") .setContentText("Auto Check In Complete at " + currentDateTimeString); mBuilder.setContentIntent(contentIntent); mBuilder.setDefaults(Notification.DEFAULT_SOUND); mBuilder.setAutoCancel(true); NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(1, mBuilder.build());

• Handling multiple accounts in Android app

  - by bebeTech

  I would like to build an application that caters for multiple accounts (eg. home, work) and account types (e.g. ISP, VoIP, Mobile). Essentially, I would like to get the user to create the accounts they want and then have all the accounts listed on the start page grouped by type. For example: ISP: - Home - Work Mobile: - Mum - Dad When you click on the account, it would take you to another screen where I do a bunch of calcs and display the results. I currently do this via multiple apps but am looking at consolidating into the one app. I am just not sure where to start or how I go about achieving this? The way the Contacts app works is a good example of what I am wanting to do.

It runs fine when I first start it and also if I pick home and then restart it; however, if I use the back arrow and then restart it it crashes on that time, but will work out the next time I start it. I think it has to do with some kind of memory build up, but I verified onDestroy is being called, I figured that deletes everything my program created, right?

• Setting values and display Text in Android Spinner

  - by kaibuki

  Hi, I need help in setting up value and display text in spinner. as per now I am populating my spinner by array adapter e.g mySpinner.setAdapter(myAdapter); and as far as I know after doing this the display text and the value of spinner at same position is same. The other attribute that I can get from spinner is the position on the item. now in my case I want to make spinner like the drop down box, which we have in .NET. which holds a text and value. where as text is displayed and value is at back end. so if I change drop down box , I can either use its selected text or value. but its not happening in android spinner case. For Example: Text Value Cat 10 Mountain 5 Stone 9 Fish 14 River 13 Loin 17 so from above array I am only displaying non-living objects text, and what i want is that when user select them I get there value i.e. like when Mountain selected i get 5 I hope this example made my question a bit more clear... thankx

• Android ListView item highlight programmatically

  - by dhomes

  Hi all, I know it's been asked around but I haven't found quite the answer yet (new to Android so sorry about the ignorance) my app's launch Activity has an EditText (called searchbox) , a ListView (designations) and a Spinner (types) I use the EditText as a searchbox, I have to pass the string through a custom editing to make searching more flexible. After that I match that against the closest approximation I find in 'designations' and do designations.setSelection(j); As expected, this sets the desired item to the top of designations. But I can find a way to highlight it via code. NOW, i do know that if the device is in touch mode the highlighting of a selected item won't occur. So the last 4 lines of my searchbox's onTextChanged event are: designations.setFocusable(true); designations.setFocusableInTouchMode(true); if (match==true) designations.setSelection(j); if (st.length()==0) designations.setSelection(0); to no avail. now, i don't have any code on searchbox's afterTextChanged(Editable s); so could anyone give me a clue on this? regards ~dh

• Android- Using DexClassLoader to load apk file.

  - by Craig O Connor

  Hi guys, I've hit a bit of a wall. Any help would be appreciated. I have an app that I want to use DexClassLoader to load another apk file. Here is my code: DexClassLoader dLoader = new DexClassLoader("/sdcard/download/test.apk","/sdcard/download",null,ClassLoader.getSystemClassLoader().getParent()); Class calledClass = dLoader.loadClass("com.test.classname"); Intent it=new Intent(this, calledClass); it.setClassName("com.test", "com.test.classname"); startActivity(it); Now I had already installed test.apk so when I ran the above code it worked fine and launched the application. However I want to be able to run this without test.apk being installed already (as that would defeat the entire point of the application) . So I uninstalled it and when I ran the my app again I get this error: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.test/com.test.classname}; have you declared this activity in your AndroidManifest.xml. So I'm a bit stumped here. This activity is declared in the Manifest of the apk I am trying to run. I can't declare it in my applications Manifest. Any ideas? Thanks, Craig

• OutofMemoryError: bitmap size exceeds VM budget (Android)

  - by Chrispix

  Getting an Exception in the BitmapFactory. Not sure what is the issue. (Well I can guess the issue, but not sure why its happening) ERROR/AndroidRuntime(7906): java.lang.OutOfMemoryError: bitmap size exceeds VM budget ERROR/AndroidRuntime(7906): at android.graphics.BitmapFactory.decodeFile(BitmapFactory.java:295) My code is pretty straight forward. I defined an XML layout w/ a default image. I try to load a bm on the SDCard (if present - it is). If not it shows the default image. Anyway.. Here is code : public class showpicture extends Activity { public void onCreate(Bundle savedInstanceState) { /** Remove menu/status bar **/ requestWindowFeature(Window.FEATURE_NO_TITLE); final Window win = getWindow(); win.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN); Bitmap bm; super.onCreate(savedInstanceState); setContentView(R.layout.showpicture); try { ImageView mImageButton = (ImageView)findViewById(R.id.displayPicture); bm = Bitmap.createScaledBitmap(BitmapFactory.decodeFile("/sdcard/dcim/Camera/20091018203339743.jpg"),100, 100, true); parkImageButton.setImageBitmap(bm); } catch (IllegalArgumentException ex) { Log.d("MYAPP",ex.getMessage()); } catch (IllegalStateException ex) { It fails on the bm=Bitmap.createScaledBitmap any thoughts? I did some research on the forums, and it pointed to this post I just don't know why it is not working. Any help would be great! Thanks, Chris.

• Android ASync task ProgressDialog isn't showing until background thread finishes

  - by jackbot

  I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. My code is as follows: class AddTask extends AsyncTask<Void, Item, Void> { protected void onPreExecute() { pDialog = ProgressDialog.show(MyActivity.this,"Please wait...", "Retrieving data ...", true); } protected Void doInBackground(Void... unused) { items = parser.getItems(); for (Item it : items) { publishProgress(it); } return(null); } protected void onProgressUpdate(Item... item) { adapter.add(item[0]); } protected void onPostExecute(Void unused) { pDialog.dismiss(); } } Which I call in onCreate() with new AddTask().execute(); The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?

• Streaming to the Android MediaPlayer

  - by Rob Szumlakowski

  Hi. I'm trying to write a light-weight HTTP server in my app to feed dynamically generated MP3 data to the built-in Android MediaPlayer. I am not permitted to store my content on the SD card. My input data is essentially of an infinite length. I tell MediaPlayer that its data source should basically be something like "http://localhost/myfile.mp3". I've a simple server set up that waits for MediaPlayer to make this request. However, MediaPlayer isn't very cooperative. At first, it makes an HTTP GET and tries to grab the whole file. It times out if we try and simply dump data into the socket so we tried using the HTTP Range header to write data in chunks. MediaPlayer doesn't like this and doesn't keep requesting the subsequent chunks. Has anyone had any success streaming data directly into MediaPlayer? Do I need to implement an RTSP or Shoutcast server instead? Am I simply missing a critical HTTP header? What strategy should I use here? Rob Szumlakowski

• Help: Android paint/canvas issue; drawing smooth curves

  - by Wrapper

  How do I get smooth curves instead of dots or circles, when I draw with my finger on the touch screen, in Android? I am using the following code- public class DrawView extends View implements OnTouchListener { private static final String TAG = "DrawView"; List<Point> points = new ArrayList<Point>(); Paint paint = new Paint(); public DrawView(Context context) { super(context); setFocusable(true); setFocusableInTouchMode(true); this.setOnTouchListener(this); paint.setColor(Color.WHITE); paint.setAntiAlias(true); } @Override public void onDraw(Canvas canvas) { for (Point point : points) { canvas.drawCircle(point.x, point.y, 5, paint); // Log.d(TAG, "Painting: "+point); } } public boolean onTouch(View view, MotionEvent event) { // if(event.getAction() != MotionEvent.ACTION_DOWN) // return super.onTouchEvent(event); Point point = new Point(); point.x = event.getX(); point.y = event.getY(); points.add(point); invalidate(); Log.d(TAG, "point: " + point); return true; } } class Point { float x, y; @Override public String toString() { return x + ", " + y; } }

• Android custom media controller using vidtry

  - by Mathias Lin

  I want to use a custom media controller in my Android app and therefore looking at the vidtry code (http://github.com/commonsguy/vidtry), especially Player.java: The sample works fine as it comes. But I want the sample to play the fixed video automatically on app startup (so I don't want to enter a URL). I added: @Override public void onStart() { super.onStart(); address.setText("/sdcard/mydata/category/1/video_agkkr6me.mp4"); go.setEnabled(true); onGo.onClick(go); } Strange thing here is that if I run the app, the audio of the video plays but the image doesn't show. Everything else works fine (progress bar, etc.). I can't figure out the difference between the manual click on the go-button and the programmatic one. I looked at the code and didn't see any difference that might occur between manual and programmatic click. I checked if any elements (esp. surface) might be hidden, but it's not. I even tried a surface.setVisibility(View.INVISIBLE); surface.setVisibility(View.VISIBLE); in case some issue with the redrawing, but no difference. The video image does show when I manually hit the go button, but just not on start up automatically.
