Question

I am having issue with memory after running many times my app.

java.lang.OutOfMemoryError: bitmap size exceeds VM budget

I figure I was leaking memory somehow so I did a DUMP HPROF file and used the MAT tool to figure out what was wrong.
It turns out that after running like 5 times the app and quiting, I find 5 instances of my Activity and 5 instances of PhoneStateListener.

If I remove the call to PhoneStateListener, I don’t have that issue anymore and I see just 1 instance of my Activity.

The question is, how do I resolve this?

Thanks

Daniel

Here is my code:

OnCreate method:

telephonyManager.listen(mPhoneListener,
                PhoneStateListener.LISTEN_SERVICE_STATE
                | PhoneStateListener.LISTEN_SIGNAL_STRENGTH
                | PhoneStateListener.LISTEN_CALL_STATE
                | PhoneStateListener.LISTEN_DATA_CONNECTION_STATE
                | PhoneStateListener.LISTEN_DATA_ACTIVITY); 

on the Activity class:

PhoneStateListener mPhoneListener = new PhoneStateListener() {
        public void onCallStateChanged(int state,
                java.lang.String incomingNumber) {
        //do something
    }
}

on onDestroy method:

telephonyManager.listen(mPhoneListener, PhoneStateListener.LISTEN_NONE);        
mPhoneListener = null;

onDestroy is not guaranteed to get called. Source: onDestroy Docs

You should try cleaning up on onPause and then onResume re-instate the stuff you need. This will help clean up some memory pressure and leaks.
