Question

Hi Lets say when i call Activity A to Activity B

below is my code become

     Intent i = new Intent(TemplateList.this, PictureEditor.class);
     Bundle b = new Bundle();
     b.putString("Key", "2");
     b.putString("Index", imagepathString);
     i.putExtras(b);
     v.getContext().startActivity(i);
     System.gc();
     Runtime.getRuntime().gc();
     finish();

Because of in Activity A there are so many objects (so many images) loaded so i am clearing that all objects by System.gc();
Runtime.getRuntime().gc(); will be cleared and also destroying activity so no any object will be stay allocated 🙂

and from Activity B i am going call to Activity A

        btnTemplate.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            startActivity(new Intent(PictureEditor.this, TemplateList.class));
            dg.dismiss();
            if (bmp != null) {
                bmp.recycle();
                bmp = null;
            }
            System.gc();
            Runtime.getRuntime().gc();
            finish();
        }
    });

//Here also i m calling System.gc and Runtime.getRuntime.gc and destroying activity but do not know why if activity A starts than i m getting

below error

Can any body solve my problem 🙁

Answer 1

Calling those methods won’t work, those methods just say to the GC that “if you want you can run now”.

Basically look for those problems:

• Isn’t the bitmap too big? -> Rescale it to the minium required size in your app.
• Are you copying the bitmap too much?
• Aren’t you leaking the bitmap by leaking the context of your Activity B?

It could come from many places but I would try to downscale it to the minimum required size in your app first.
