  • Simple question about the lunarlander example.

    - by Smills
    I am basing my game off the lunarlander example. This is the run loop I am using (very similar to what is used in lunarlander). I am getting considerable performance issues associated with my drawing, even if I draw almost nothing. I noticed the below method. Why is the canvas being created and set to null each cycle? @Override public void run() { while (mRun) { Canvas c = null; try { c = mSurfaceHolder.lockCanvas();//null synchronized (mSurfaceHolder) { updatePhysics(); doDraw(c); } } finally { // do this in a finally so that if an exception is thrown // during the above, we don't leave the Surface in an // inconsistent state if (c != null) { mSurfaceHolder.unlockCanvasAndPost(c); } } } } Most of the times I have read anything about canvases it is more along the lines of: mField = new Bitmap(...dimensions...); Canvas c = new Canvas(mField); My question is: why is Google's example done that way (null canvas), what are the benefits of this, and is there a faster way to do it?

  • Texture repeats even with GL_CLAMP_TO_EDGE set

    - by Lliane
    Hi, i'm trying to put a translucing texture on a face which uses points 1 to 4 (don't mind the numbers) on the following screenshot Sadly as you can see the texture repeats herself in both dimensions, I tried to switch the TEXTURE_WRAP_S from REPEAT to CLAMP_to_EDGE but it doesn't change anything. Texture loading code is here : gl.glBindTexture(gl.GL_TEXTURE_2D, mTexture.get(4)); gl.glActiveTexture(4); gl.glTexParameterf(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MIN_FILTER, gl.GL_LINEAR); gl.glTexParameterf(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MAG_FILTER, gl.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexImage2D(gl.GL_TEXTURE_2D, 0, gl.GL_RGBA, shadowbmp.width, shadowbmp.height, 0, gl.GL_RGBA, gl.GL_UNSIGNED_SHORT_4_4_4_4, shadowbmp.buffer); Texture coordinates are the following : float shadow_bot_text[] = { 0.0f, 0.0f, 0.0f, 1.0f, 1.0f, 0.0f, 1.0f, 1.0f }; Thanks

  • Efficiently using position to control actions

    - by John Ashmore
    I want to use position (returned from a gridview for e.g.) or a similar numeric integer to do various things, e.g. create a sprite, or in any command that wants something other than a number, e.g. I want to use something like: sprites.add(createSprite(R.drawable.image(position)); , where createSprite creates a sprite using the image supplied, instead of: if (position == 1) {sprites.add(createSprite(R.drawable.image1);} if (position == 2) {sprites.add(createSprite(R.drawable.image2);} ...etc There is an easy solution for strings: Most efficient method to use position to open a .java but what about for situations like this one?

  • Null Pointer Exception in my BroadcastReceiver class

    - by user1760007
    I want to search a db and toast a specific column on the startup of the phone. The app keeps crashing and getting an exception even though I feel as the code is correct. @Override public void onReceive(Context ctx, Intent intent) { Log.d("omg", "1"); DBAdapter do = new DBAdapter(ctx); Log.d("omg", "2"); Cursor cursor = do.fetchAllItems(); Log.d("omg", "3"); if (cursor.moveToFirst()) { Log.d("omg", "4"); do { Log.d("omg", "5"); String title = cursor.getString(cursor.getColumnIndex("item")); Log.d("omg", "6"); // i = cursor.getInt(cursor.getColumnIndex("id")); Toast.makeText(ctx, title, Toast.LENGTH_LONG).show(); } while (cursor.moveToNext()); } cursor.close(); } The frustrating part is that I don't see any of my "omg" logs show up in logcat. I only see when my application crashes. I get three lines of errors in logcat. 10-19 12:31:11.656: E/AndroidRuntime(1471): java.lang.RuntimeException: Unable to start receiver com.test.toaster.MyReciever: java.lang.NullPointerException 10-19 12:31:11.656: E/AndroidRuntime(1471): at com.test.toaster.DBAdapter.fetchAllItems(DBAdapter.java:96) 10-19 12:31:11.656: E/AndroidRuntime(1471): at com.test.toaster.MyReciever.onReceive(MyReciever.java:26) For anyone interested, here is my DBAdapter fetchAllItems code: public Cursor fetchAllItems() { return mDb.query(DATABASE_TABLE, new String[] { KEY_ITEM, KEY_PRIORITY, KEY_ROWID }, null, null, null, null, null); }

  • How to set webview scroll position within it on initial launch ?

    - by mob-king
    I have an issue with Webview to set the initial scroll position within it when first launched. By default it is left , I want it to scroll and show the view from center. Or is it possible to resize the view to fit the screen width initially, instead of scroll bars. I need this since the left part of the page I am loading is blank making user feel the page is not loaded.

  • Bitmap .compress() returning false

    - by Tsimmi
    Hi! The next call to Bitmap.compress(), has a different behavior on the Emulator and on a real device. In the Emulator, result is true, and in a real device the same call returns false. FileOutputStream fos = new FileOutputStream(destinationFile, true); boolean result = myBitmap.compress(Bitmap.CompressFormat.PNG, 100, fos); The thing is that on the emulator this is working great, on a real device ( a HERO) when calling .compress(), this returns false, witch means that it was unable to convert the image properly. Why is this? Thank you

I want to count the number of times b element is present (its variable) And i want this count before parsing, so that I can declare an array of appropriate size. One way is to run count then separately and other way is dynamic array (List Array) Is there any other better way to do this? Also, Is it possible to make an ArrayList of my class..? because I want an array of type myClass.

  • Error Instantiating an Inner Class in Parent's Constructor...

    - by stormin986
    In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class. public class MainApplication extends Application { public class Data { public String x; public String y; public String z; } private Data data; MainApplication() { data = new Data() data.x = "String"; } } After I instantiate the object in the constructor, I get a runtime error when I try to assign any of the inner class object's variables.

  • What could possibly be causing this NPE in onCreate?

    - by Adam Johns
    I am getting an NPE in onCreate of the following file (MySubActivity): public class MySubActivity extends MySuperActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); myTextView.setText(getResources().getString(R.string.myString)); } } MySuperActivity: public class MySuperActivity extends Activity { protected TextView myTextView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.my_layout); myTextView = (TextView)findViewById(R.id.myTextViewid); } } The strange thing is that I have never seen this crash while testing the app. The page works fine when I test it. However I got a crash report from Google notifying me of the crash. I cannot reproduce it, and I have no idea under what scenario this crash could happen. Seeing as how it works for me, the resource ids and string names etc. must be correct. The only thing that came across my mind was that maybe the user had their phone set to a different language, so it couldn't properly pull the resources. However, there are default resources for all of them, and I tested changing the language of my emulator and it didn't crash. Any ideas?

  • Getting contacts when ids are known

    - by frieza
    Hi, I have a list of 'n' contact ids corresponding to which I need to obtain the contact details. One simple way to make n queries using the contact ids and retrieve those contacts. But this will be very time-consuming especially if n is large. I would like to know if there is any simpler way to obtain these results (like batch query etc).

  • Bitmap size exceeds VM budget after second load

    - by jonny
    This is driving me crazy. I have a game which has a bitmap as the background, this is big so I scale it down and this works fine. However when I navigate to another activity and then reload the game screen it crashes on drawing the background. I am calling recycle on all the bitmaps and setting them to null on onDestroy() but this doesn't help. Any ideas and if not how can I debug the memory to see at which step its growing. I looked at getting the heap but nothing of any size is on there really. Thanks.

  • What values does Camera.Parameters.set("picture-size", ?) take?

    - by mobilekid
    Hi, my app involves some work with the camera, therefore it needs to handle capturing of images with different resolution. My targets are 1.6 - onwards. Does anyone know what to pass in the value argument for Camera.Parameters.set("picture-size", value) I have look at the Donut release of the Camera app, however, it was not very clear what exactly has been used there as the value is retrieved from the SharedPreferences. // Set picture size parameter. String pictureSize = mPreferences.getString(CameraSettings.KEY_PICTURE_SIZE, getString(R.string.pref_camera_picturesize_default)); mParameters.set(PARM_PICTURE_SIZE, pictureSize); Lookin at the strings.xml I can see that R.string.pref_camera_picturesize_default = 2048x1536, however, I'm not sure what other values can be passed there? Is it any resolution you fancy, or are they only certain resolutions the drivers can handle? Thanks.
