  • 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.)

  • Thread used for ServiceConnection callback (Android)

    - by Jannick
    Hi I'm developing an activity that binds to a local service (in onCreate of the activity): bindService(new Intent(this, CommandService.class), svcConn, BIND_AUTO_CREATE); I would like to be able to call methods through the IBinder in my lifecycle methods, but can not be sure that onServiceConnected have been called prior to these. I'm thinking of handling this by adding a queue of sorts in the ServiceConnection implementation, so that the method calls (Command pattern) will be executed once the connection is established. My questions are then: Is this stupid, any better ways? :) Are there any specification for which thread will be used to execute the ServiceConnection callbacks? More to the point, do I need to worry about synchronizing a queue datastructure? Edit - something like: public void onServiceConnected(ComponentName name, IBinder service) { dispatchService = (DispatchAsync)service; for(ExecutionTask task : queue){ dispatchService.execute(task.getCommand(), task); } }

  • Android: heavy traffic on server causes app to force close

    - by user522559
    I have developed an app to communicate with my own server and published it. However, sometimes the app force closes. I know there is no bug in the code because the app works properly most of the time, but sometimes it is waiting for an answer from the server forever. I think this is due to the fact that so many people are using the app, and the app refreshes every 1 second or so, so this heavy traffic causes the server to take a large amount of time to respond. So how do you take care of such a use case? should I have a use case where if the server does not respond after some time you just stop the app and throw a message saying that the server is not responding or something like that?

  • Android: stack management for views in a tab?

    - by wei
    I see some answers here prefer views over activities as contents of tabs. Correct me if I am wrong. My understanding is that by switching out views, it's possible to keep the navigation flow inside a tab (more user friendly, I think). But I wonder how to manage the view stack then in case of the back button events. Also this could cause one giant Activity with large amount of views, which might not be good. So I wish to know why exactly views as contents is preferred before I change my current application to this. Thanks,

  • Style first 2 TextViews in Android ListView differently

    - by Kurtis Nusbaum
    I have a ListView and I want the first two entries in it to be displayed differently than the rest. Nothing fancy, I want them all to just be text views. But the first two entries need to have different sizes and weights than the rest. I tried modifying the ArrayAdapter class like so: private class BusStopAdapter<T> extends ArrayAdapter<T>{ public BusStopAdapter( Context context, int textViewResourceId, List<T> objects) { super(context, textViewResourceId, objects); } public View getView(int position, View convertView, ViewGroup parent) { TextView toReturn = (TextView)super.getView(position, convertView, parent); if(position == 0){ toReturn.setTextSize(12); toReturn.setText("Previous Bus: " + toReturn.getText()); toReturn.setPadding(0,0,0,0); } else if(position == 1){ toReturn.setTextSize(20); toReturn.setPadding( toReturn.getPaddingLeft(), 0, toReturn.getPaddingRight(), 0 ); toReturn.setText("Next Bus: " + toReturn.getText()); toReturn.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.TOP); } return toReturn; } } But this inadvertantly causes some of the other textviews to take on these special attributes. I think it's because cause textviews get "recycled" in the AbsListAdapter class.

  • Getting error using ContactManager Sample

    - by OceanBlue
    I have created some contacts data in the emulator. When I run the ContactManager sample app downloaded from the Android site, I get an error. Specifically, when trying to add a Contact through the app, I get a NullPointerException. I think it is because the "Target Accounts" spinner on the scree is not getting populated, and hence I cannot select a Target Account before adding a contact. Has anyone run across this problem or has any clues on how to fix this?

Basically I just can a icon that they can press which will flip the value of a boolean in the broadcast receiver, and change the icon to indicate something happened.

  • back button android

    - by Raogrimm
    i am having trouble implementing the back button properly. all of the code snippets i have seen have not worked for me. what i am trying to do when i press the back button is just go back to the previous list. pretty much i have a list within a list and i just want it to go back to the previous list. how would i go about doing this? this is the list i have, every item has a separate list that it has. lets say you click on weapons, you then get a list of different weapon types and so on final String[] weapons = getResources().getStringArray(R.array.weapons); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, weapons)); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { System.out.println("item clicked: "+weapons[position]); switch(position) { case 0: final String[] axes = getResources().getStringArray(R.array.axes); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, axes)); break; case 1: final String[] clubs = getResources().getStringArray(R.array.clubs); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, clubs)); break; case 2: final String[] daggers = getResources().getStringArray(R.array.daggers); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, daggers)); break; case 3: final String[] great_axes = getResources().getStringArray(R.array.great_axes); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, great_axes)); break; case 4: final String[] great_katana = getResources().getStringArray(R.array.great_katana); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, great_katana)); break; case 5: final String[] great_swords = getResources().getStringArray(R.array.great_swords); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, great_swords)); break; case 6: final String[] hand_to_hand = getResources().getStringArray(R.array.hand_to_hand); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, hand_to_hand)); break; case 7: final String[] katana = getResources().getStringArray(R.array.katana); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, katana)); break; case 8: final String[] polearms = getResources().getStringArray(R.array.polearms); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, polearms)); break; case 9: final String[] scythes = getResources().getStringArray(R.array.scythes); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, scythes)); break; case 10: final String[] staves = getResources().getStringArray(R.array.staves); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, staves)); break; case 11: final String[] swords = getResources().getStringArray(R.array.swords); setListAdapter(new ArrayAdapter<String>(ffxidirectory.this, R.layout.list_item, swords)); break; } } });

  • ImageViews sometimes not displaying in FrameLayout activity

    - by Ken
    The top level layout in my activity is a framelayout. I have completed, debugged and tested this app and it works exactly like it should in all respects on my g1 and on various emulators. But on 3.7-inch displays running 2.1+, some imageviews packed in a linearlayout are periodically not visible. I know that they are there because you can touch and drag them with effect in the app. So I assume somehow they have gotten under the SurfaceView that is the main component of the app. This is apparently so even though the SurfaceView is declared in the xml prior to the LinearLayout. However, the ImageViews IN the LinearLayout are added programmatically towards the end of onCreate(). Framelayout stacks everything that is added to it, one on top of the other--the only way you will see more than one child of a frame layout is if they are smaller than the screen and are placed apart from eachother. Oddly, sometimes the imageviews ARE visible--it is random. Anyway, I've been trying to combat this with framelayout.bringChildToFront(View v) on the linearlayout without success. I wonder if anyone has any insight into how the behavior could be random like that, and how I should code these imageviews to keep this from happening, and why the problem appears only to occur on 3.7 vs 3.2 inch screens (as it happens, the two 3.2-inch screens were both htc, so vendor might be factor too). [edit] Actually, I've determined that this is a 2.2 issue, not a screen size (or even vendor) issue. Can't ensure that ImageViews added to a framelayout with a SurfaceView in it will appear on top of the surfaceview. I ran some tests in the respective onDraw() methods and the imageviews are 'visible' (0), and nothing does anything to the alpha of the drawables, which are there as well at ondraw(). [/edit] Any insight would be welcomed. Ken T.

  • Android Google maps co-ordinates

    I have an app which stores co-ordinates. I am using Google maps to show the location to allow full use of the maps app. I am using the intent call and placing the co-ordinates in the q=xxxxxxxxx,xxxxxxxxx part. This works, however when Google maps shows the location it often finds a point on the road, sometimes a little distance from the actual co-ordinates. Is there a way to get maps to show the actual point?
