  • Handling Application Logic in Multiple AsyncTask onPostExecute()s

    - by stormin986
    I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. The only way I can find that this is possible is if both AsyncTasks' onPostExecute() executed SO simultaneously that they were virtually running the same lines at the same time, since I set the 'itemXdownloaded' flag to true right before I check for both and call startActivity(). But this is happening enough that it's very hard for me to believe that both downloads are finishing precisely at the same time and having their onPostExecute()s so close together... Any thoughts on what could be going on here? General gist of code (details removed, ignore any syntactical errors I may have edited in): // In onPostExecute() switch (downloadID) { case DL1: dl1complete = true; break; case DL2: dl2complete = true; break; case DL3: dl3complete = true; break; } // If 1 and 2 are done, move on (DL3 still going in background) if ( downloadID != DL3 && dl1complete && dl2complete) { ParentClass.this.startActivity(new Intent(ParentClass.this, NextActivity.class)); }

  • Is there a FAST way to export and install an app on my phone, while signing it with my own keystore?

    - by Alexei Andreev
    So, I've downloaded my own application from the market and installed it on my phone. Now, I am trying to install a temporary new version from Eclipse, but here is the message I get: Re-installation failed due to different application signatures. You must perform a full uninstall of the application. WARNING: This will remove the application data! Please execute 'adb uninstall com.applicationName' in a shell. Launch canceled! Now, I really really don't want to uninstall the application, because I will lose all my data. One solution I found is to Export my application, creating new .apk, and then install it via HTC Sync (probably a different program based on what phone you have). The problem is this takes a long time to do, since I need to enter the password for the keystore each time and then wait for HTC Sync. It's a pain in the ass! So the question is: Is there a way to make Eclipse automatically use my keystore to sign the application (quickly and automatically)? Or perhaps to replace debug keystore with my own? Or perhaps just tell it to remember the password, so I don't have to enter it every time...? Or some other way to solve this problem?

  • How can you tell if an activities state is stored?

    - by Joren
    I have an activity which pulls some JSON from my server, and then uses it to draw a list. That list launches further activities. My problem is that I can't figure out a way to tell if the activity is still alive when you go back to it, so I end up re-querying my JSON from the server and redrawing the list every time the user goes back to the activity. How can I tell if my activity is still alive so I can skip the redraw?

  • How to schedule an alarm so that the intent is broadcast everytime the date changes?

    - by rogerstone
    I want to schedule an alarm which throws an intent when the date changes. I know that this would do this the job alarms.setRepeating(AlarmManager.RTC_WAKEUP,triggerAtTime, interval,alarmIntent); But what is confusing me is what to put in the triggerAtTime and the interval.It says System.currentTimeMillis() timebase. I might be installing the app on any day so the TriggerAtTime should be midnight of that day and the interval would be 24 hours from there on. How can I acheive this.Can someone tell me what to put in TriggerAtTime and interval in the required format. Thanks

  • Closing inputstreams

    - by Nick
    I have the below code to read from a URL object: URL url= new URL("http://datasource.com"); BufferedReader reader = new BufferedReader( new InputStreamReader(url.openStream())); After I am done getting the data, is this sufficient to close and release all the resrouces: reader.close(); I did not see a method for URL to close it, like URL.close()...but wondering if I shouldn't do something more like this: InputStreamReader inputStreamReader = new InputStreamReader(url.openStream()); BufferedReader reader = new BufferedReader(inputStreamReader); // Do Stuff inputStreamReader.close(); reader.close();

  • How can I create a new class instance from a class within a (static) class?

    - by Mervin
    I'm new to Java (have experience with C#), This is what i want to do: public final class MyClass { public class MyRelatedClass { ... } } public class OtherRandomClass { public void DoStuff() { MyRelatedClass data = new MyClass.MyRelatedClass(); } } which gives this error in Eclipse: "No enclosing instance of type BitmapEffects is accessible. Must qualify the allocation with an enclosing instance of type BitmapEffects (e.g. x.new A() where x is an instance of BitmapEffects)." this is possible in C# with static classes , how should it be done here?

  • How can I make my Virtualbox Vista see my USB device (iPad)?

    - by phil
    I have the latest VirtualBox. I have filters for the iPad. But it does not show up in my virtual Windows vista My Computer screen or virtual iTunes. When I try to right click the little USB icon and select it it says it failed because the device is busy with a previous request Result code: E_INVALIDARG (0X80070057) Component: HostUSBDevice Interface: IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a} Callee: IConsole {515e8e8d-f932-4d8e-9f32-79a52aead882} Any help is greatly appreciated Note: running 64bit Windows Vista Virtual on a 64bit Windows Vista (Home Premium) EDIT: my iPad is in recovery mode, maybe why it can't be seen in virtualbox? Also my host is running Zonealarm firewall and Microsoft Security Essentials. In addition the guest has AVG antivirus. Could those programs conflict with virtualbox?

  • Accessing database problem

    - by anarche
    Ok, so I've got an SQLiteOpenHelper that prepares and returns a SQLiteDatabase object; this is written singleton-pattern, so the database is opened once and only closed when the Activity closes. From there I have three database wrappers encapsulating the queries (some returning cursors to datasets, some inserting data) used by the Activity. I want to insert data from one View, then have that automatically update in another View on the same Dialogue. I'm writing this on a notepad and testing on the phone (since the emulator crashes the notepad...), so I can't pull up stacktraces atm. So questions: 1) are there limitations to writing to a database, when there are cursors open on the database? 2) Does a Cursor.requery()? call update the ListView with the cursor as a data connector?

  • How to Use Eclipse to Debug JNI code (Java & C/C++)

    - by tkryger
    While I can debug my application with the Eclipse JDT debugger for Java code and GDB for C code, I would prefer to use a single tool for all my debugging. I found several projects that enable "mixed-mode" debugging in Eclipse and include support for single stepping between Java and native code. Intel's Integrated Debugger for Java/JNI Environments Mariot Chauvin's Summer of Code Project: Support Seamless Debugging between JDT & CDT Unfortunately, one claims to be pre-release quality and the other is currently unmaintained. Are there any plug-ins that bring mixed mode debugging functionality to Eclipse in a reliable way or should I continue to use two separate debuggers?

  • Noob Droid Question regarding random number

    - by Pete Herbert Penito
    Brand new to droid programming, but would love to learn as much as possible, so I finally got my emulator working correctly, I even got a hello world button to work, I'm attempting to make this button display a random number, I've googled this and came up with this code: Random generator = new Random(); int n = generator.nextInt(n); I fixed the Random function by including some Random java utility. I'm assuming this code above goes in the .java file of the project, so my button code looks as follows (tested and works): PopUpText.makeText(v.getContext(), "Hello World", PopUpText.LENGTH_LONG).show(); I figured I could replace "Hello World" with n to display the number in the box, however the following error is stopping the compile: The local variable n may not have been initialized Any ideas why this is happening? Any advice would be hugely appreciated.

  • Why is my onSharedPreferenceChangeListener being called multiple times when I change a pref.

    - by brockoli
    I've written an app with 3 tabs. Each tab has the same list view with different data sources. I have setup SharedPreferences in the tabhost activity, but I put my onSharedPreferenceChangeListener method in my listactivity. When I change a preference, my listener gets called and it updates my database. This is all working. However, if I change the data in tab 1, it calls my listener once. If I change the data for tab 2 it calls it twice and if I change the data in tab 3 it calls it three times. Any idea why it works this way? I guess I could setup my shared prefs in my listactivity and that might avoid the issue, but I'm curious why my listener is called multiple times if it's in a different tab. brockoli

  • Androids ExpandableListView - where to put the button listener for buttons that are children

    - by CommonKnowledge
    I have been playing around a lot with the ExpandableListView and I cannot figure out where to add the button listeners for the button that will be the children in the view. I did manage to get a button listener working that uses getChildView() below, but it seems to be the same listener for all the buttons. The best case scenario is that I would be able to implement the button listeners in the class that instantiates the ExpandableListAdapter class, and not have to put the listeners in the actual ExpandableListAdapter class. At this point I don't even know if that is possible I have been experimenting with this tutorial/code: HERE getChildView() @Override public View getChildView(int set_new, int child_position, boolean view, View view1, ViewGroup view_group1) { ChildHolder childHolder; if (view1 == null) { view1 = LayoutInflater.from(info_context).inflate(R.layout.list_group_item_lv, null); childHolder = new ChildHolder(); childHolder.section_btn = (Button)view1.findViewById(R.id.item_title); view1.setTag(childHolder); childHolder.section_btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Toast.makeText(info_context, "button pushed", Toast.LENGTH_SHORT).show(); } }); }else { childHolder = (ChildHolder) view1.getTag(); } childHolder.section_btn.setText(children_collection.get(set_new).GroupItemCollection.get(child_position).section); Typeface tf = Typeface.createFromAsset(info_context.getAssets(), "fonts/AGENCYR.TTF"); childHolder.section_btn.setTypeface(tf); return view1; } Any help would be much appreciated. Thank you and I will be standing by.

  • PendingIntent sent from a notication.

    - by totem
    Hi, What im trying to accomplish is to send a notification through the notification manager that once clicked will do something in the application only if its currently running. i have tried to use: notification.contentIntent = PendingIntent.getActivity(this, nNotificationCounter, Someintent, PendingIntent.FLAG_NO_CREATE) Which allways caused an exception once trying to use the notify. I switched to: Notification notification = new Notification(icon, tickerText, when); RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.some_notification); contentView.setTextViewText(R.id.title, sTitle); contentView.setTextViewText(R.id.text, sText); notification.contentView = contentView; notification.defaults |= Notification.DEFAULT_SOUND; notification.number = nNotificationCounter; Intent notificationIntent = new Intent(this, MainWindow.class).setAction(ACTION_RESET_MESSGE_COUNTER); notification.contentIntent = PendingIntent.getBroadcast(this, nNotificationCounter, notificationIntent, 0); and although this code doesn't cause an exception. it doesnt call my BroadcastReceiver which is defined as follows: public class IncomingReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(ACTION_RESET_MESSGE_COUNTER)) { System.out.println("GOT THE INTENT"); return; } } } and set in the onCreate: IntentFilter filter = new IntentFilter(ACTION_RESET_MESSGE_COUNTER); IncomingReceiver receiver = new IncomingReceiver(); context.registerReceiver(receiver, filter); Does anyone see something wrong with the code? Or how would i go about to get messages when the notification is clicked, but not create any activity if it isn't already created. edit: added the intent creation and notification creation. Thanks, Tom
