  • 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 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.

  • 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.

  • 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

  • Launching an activity at its current state.

    - by Profete162
    Hello, I am trying to make a task switcher and i succed in it. My only problem is that when I launch activities, they are relaunched as they were new activities ( for instance, I am writing an email, i press home and go into my activity,launch email, and then the app launch the email bout goes back at the inbox and the email is lost) So that's not true multitasking. Here are my steps: 1) getting all the running apps: List<ActivityManager.RunningTaskInfo> allTasks = activityManager.getRunningTasks(30); 2) getting the intent: for (ActivityManager.RunningTaskInfo aTask : allTasks) { Intent i = new Intent(Intent.ACTION_MAIN); i.setComponent(aTask.baseActivity); (...) 3) Launching the application when clicking on the button: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK| Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED).addCategory(Intent.CATEGORY_LAUNCHER); monthis.startActivity(intent); ` What is wrong with this code? Should I do something different to get it? Thank a lot for any answer.

  • Dismiss a custom dialog?

    - by YaW
    Hi, I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code: //Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.custom_dialog_simple, (ViewGroup) findViewById(R.id.rlDialogSimple)); //Change Text and on click TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple); tvDialogSimple.setText(R.string.avisoComprobar); Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple); btDialogSimple.setOnClickListener(new OnClickListener() { public void onClick(View v) { //Do some stuff //Here i want to close the dialog } }); AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this); builder.setView(layout); AlertDialog alert = builder.create(); alert.show(); So, i want to dismiss the dialog in the onClick of btDialogSimple. How i can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so i don't want to make a builder.setPositiveButton. Any ideas?

  • When I get the Force Close dialog, I have a Report button. Where did it come from?

    - by BenTobin
    I feel a little bit silly asking this, but I haven't been able to find any answers on my own. My Force Close dialog has a "Report" button. I think it's a great idea, and I wish everyone had it. At first, I thought it must be something I turned on without realizing it, but not only can't I find any setting that I might have touched, I also can't find any reference to this button existing on the Internet. I have a Droid, and I know 4 other people with Droids, and they say they don't have the option to report Force Closes. Am I special? Am I just missing something? The "report" button has been there for at least a few weeks now. When I use the Report button, I get a screen with a "feedback" field and a checkbox for "Include system data". Below that , it says "Information from feedback reports will be shown to the developer of the application." Under that are Preview and Send buttons. As a developer, I've never received one of these reports. I'd try to send a report to myself, but it seemingly only shows the button for apps installed from the market, and I don't know of a way to crash my production app. I suppose I could publish a simple crashing app just to try it out, but I thought I'd ask you folks first. Edit: You can view screenshots here: http://bentobin.com/crashReportImages/

  • 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

  • Exception in DatePickerDialog

    - by Miya
    Hi, i am trying to create a DatePickerDialog in the class 'dateDisplay.class'. I am calling this activity from 'main.class'. If I call the 'dateDisplay.class' using startActivity(), then the DatePickerDialog works fine. But actually I am using an ActivityGroup (for using tab in my application) and I am starting the 'dateDisplay.class' using the following code : Intent dateIntent=new Intent(context,dateDisplay.class); View v=getLocalActivityManager().startActivity("2",dateIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); setContentView(v); But an exception is caught, on calling the onCreateDialog() function. And the process is suddently stopped. It shows TargetInvocationException is occured. How can I correct the code? Following is my code: public Dialog onCreateDialog(int id,Bundle b) { Calendar c=Calendar.getInstance(); int day=c.get(Calendar.DAY_OF_MONTH); int month=c.get(Calendar.MONTH); int year=c.get(Calendar.YEAR); Dialog d = null; if(id==DATE_DIALOG_ID) { return new DatePickerDialog(this,dateChangeListener,year,month,day); } else { return null; } } Please help me.. Thank you..
