I have a children tale app - 18 pages, each page is an activity with a background image, short story and sound for every word(textView) in a story, and some animations.

I notice, when i go to next page, the memory is consumed;

it is also consumed when i go back to previous page(activity)! I get outOfMemory exception when the app reaches about 182MB usage - this can happen anytime.

r

  • How do I release images if the image is a background for RelativeLayout in every page ?

  • every time i navigate to next page, the previous is destroyed - should not the images it loads be released from memory as well?

    public class Page8 extends Activity{
    ImageView forward ;
    ImageView backward ;
    RelativeLayout main ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    
    super.onCreate(savedInstanceState);
    setContentView(R.layout.page8);
    forward = (ImageView)findViewById(R.id.to_page_9);
    backward = (ImageView)findViewById(R.id.to_page_7);
    forward.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() != MotionEvent.ACTION_DOWN) return false;
            Intent intent = new Intent(Page8.this, Page9.class);
            startActivity(intent);
            return true;
        }
    });
    backward.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() != MotionEvent.ACTION_DOWN) return false;
            Intent intent = new Intent(Page8.this, Page7.class);
            startActivity(intent);
            return true;
        }
    });
    }
       @Override
       public void onStop(){
       main = (RelativeLayout)findViewById(R.id.main) ;
       main.releaseMemory()?;
    
      }
     }

I think you have HD images, you should optimize images and scale down them.
