My app frequently throws exception like below:
E/WindowManager( 6282): android.view.WindowLeaked: Activity com.myActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@4479b710 that was originally added here
The app shows a progress dialog when the main activity starts and starts a task. When the task is done, it will dismiss the progress dialog.
My code is like below. Can someone help me?
public class MyActivity extends Activity {
private static int ID_DIALOG_PROGRESS = 2001;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_activity);
showDialog(ID_DIALOG_PROGRESS);
new MyTask().execute(null, null, null);
}
@Override
protected Dialog onCreateDialog(int id) {
if (id == ID_DIALOG_PROGRESS) {
ProgressDialog loadingDialog = new ProgressDialog(this);
loadingDialog.setTitle("");
loadingDialog.setMessage("");
loadingDialog.setIndeterminate(true);
loadingDialog.setCancelable(false);
return loadingDialog;
}
return super.onCreateDialog(id);
}
private class MyTask extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... arg0) {
/* Do something expensive here...*/
/* Start other activity*/
Intent intent = new Intent(MyActivity.this, OtherActivity.class);
startActivityForResult(intent, 1000);
}
return null;
}
protected void onPostExecute(Void arg0) {
dismissDialog(ID_DIALOG_PROGRESS);
}
}
}
Most of the time, the exception was thrown from showDialog() call. The other time, the exception was thrown from dismissDialog() call.
Thank you in advance!
You're starting a new activity in doInBackground()
before you dismiss the dialog in onPostExecute()
, which is probably what is causing the dialog to leak. I would move
Intent intent = new Intent(MyActivity.this, OtherActivity.class);
startActivityForResult(intent, 1000);
to onPostExecute()
after the dismissDialog()
call and see what happens.
