Async task freeze on Android
I have weird problem with my Activity and I dont know what to do...
private Bitmap mBitmap;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
mBitmap = initBitmap();
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menuItemNew:
doSomething();
return true;
case R.id.menuItemNative:
showList();
return true;
}
return(super.onOptionsItemSelected(item));
}
private boolean selected;
private void showList() {
CharSequence[] items = {"First", "Second"};
selected = false;
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Selection mode");
builder.setSingleChoiceItems(items, 0, new OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
selected = item == 1;
}
});
builder.setPositiveButton("OK", new OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
if (selected) {
new NativeTask().execute();
}
}
});
Dialog dia = builder.create();
dia.show();
}
private class NativeTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... params) {
Log.i("task", "before Native Call");
int buffer[] = new int[mBitmap.getWidth() * mBitmap.getHeight()];
mBitmap.getPixels(buffer, 0, mBitmap.getWidth(), 0, 0, mBitmap.getWidth(), mBitmap.getHeight());
int[] result = NativeLibrary.process(pixels);
Log.i("task", "after Native Call");
return null;
}
@Override
protected void onProgressUpdate(String... progress) {
Log.i("task", "in progress");
}
@Override
protected void onPostExecute(String a) {
Log.i("task", "in postExecute");
}
}
This is relevant part of my Activity. As you see, I have menu there and if you click on second item, dialog with list of 2 items appears. Then if you select and confirm second item in list, AsyncTask is being executed and some method from native code is called.
Looks good (for me), but some problem is there - when I select second item from list, native method is correctly called... but Activity freezes.
Log contains all three messages:
- task: before Native call
- task: after Native call
- task: in postExecute
I don't know what more I have to do. Am I missing something? Why is my Activity freezing when I use AsyncTask? Is problem I'm working with Bitmap inside AsyncTask? NativeLibrary.process(int[]) return correct array, no problem there.... so WHY?
I will be happy for any tip!
P.S: I'm sorry for my bad english
EDIT: Here's log for freeze

in this second case it doesnt freese but Activity crashes...
EDIT: I found weird memory leak in Native part and when I fixed it, everything is ok :)
I am confused as the declaration of NativeTask declares that it takes a Parameter(s) of type String as in:
new NativeTask().execute(string1);
not
new NativeTask().execute();
also you do not seem to use the string parameter in doInBackground as:
String inString= params[0];
Hope that helps, JAL
I found some memory leak in native part. When I fixed it, everything works correct.
