Hi, built a simple app that displays an alertDialog with two buttons.
The problem is it's not getting dismissed when i change orientation.
After change i get a leak warning on debugger and the dialog appears
twice(pressing back hides the first dialog, only a second back
dismisses it completely). Any ideas?
Here is my code:
public class MyActivity extends Activity {
private static final int TEST_DIALOG = 0;
private AlertDialog alert;
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.showDialog(TEST_DIALOG);
}
@Override
protected Dialog onCreateDialog(int id) {
switch(id){
case TEST_DIALOG:
AlertDialog.Builder builder = new
AlertDialog.Builder(this);
alert = builder.create();
alert.setMessage("Test Message");
alert.setButton("Start", new
DialogInterface.OnClickListener(){
public void onClick(DialogInterface arg0, int arg1){
alert.dismiss();
}
});
alert.setButton2("Exit", new
DialogInterface.OnClickListener(){
public void onClick(DialogInterface arg0, int arg1){
MyActivity.this.finish();
}
});
return alert;
}
return alert;
}
@Override
protected void onDestroy() {
super.onDestroy();
if(alert!=null)
alert.dismiss();
}
}
Warning i get:
Activity com.example.MyActivity has leaked window
com.android.internal.policy.impl.PhoneWindow$Decor v...@43b29210 that

When changing orientation the activity gets destroyed and recreated
but after onCreate has finished creating the dialog, onCreateDialog is
run again, why is this happening?
