Android: Memory leak due to AsyncTask

Question

I\'m stuck with a memory leak that I cannot fix. I identified where it occurs, using the MemoryAnalizer but I vainly struggle to get rid of it. Here is the code:

<         


        

Answer 1

Is your thread garbage collected after onPostExecute is called or is it still in the memory?

A Async Task will not be canceled or destroyed at the moment the activity is dismissed. If your thread is more or less lightweight and finishes after a small time, just keep it running and add a MyActivity.this.isFinishing() clause in the onPostExecute() method.

Your Task stores a implicit reference to your Activity MyActivity.this because it is a private class inside the activity. This means that your Activity will not be garbage collected until the task exits.

Answer 2

You can try below code snippet

protected void onPostExecute(Boolean result) {
    if(YourActivity.this.isFinished()){
        //to smomething here
    }
}
