title: how can I clear growing heap?
body: <p>I have a project which works as a presentation of ImageViews with animation of them by clicking. It is realized as a ViewFlipper with go_in and go_out animation. Each ImageView is featured in XML for each slide of presentation. App is made for tabs with Android 3.0 and higher. Size of heap grows with each switching and logcat looks like (before dalvik gives an error: oof) ...  </p>

  <p>SO, the question is - how is it possible to null heap or restart the application? Or how organize the app not giving it to increase heap?</p>
  
  <p>Here is the code I used</p>
  
  <pre><code>ImageView buttonNext_13 = (ImageView)findViewById(R.id.Button_next_13);
  buttonNext_13.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View view131) {
          flipper.setInAnimation(AnimationUtils.loadAnimation(
              view131.getContext(), R.anim.go_next_in));
          flipper.setOutAnimation(AnimationUtils.loadAnimation(
              view131.getContext(), R.anim.go_next_out));
          flipper.showNext();
          mp_file.release();
          mp_file = MediaPlayer.create(getApplicationContext(), R.raw.theme);
          mp_file.start();
          return;
      }
  });
  ImageView buttonPrevious_13 = (ImageView)findViewById(R.id.button_preious13);
  buttonPrevious_13.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View view132) {
          flipper.setInAnimation(AnimationUtils.loadAnimation(
              view132.getContext(), R.anim.go_prev_in));
          flipper.setOutAnimation(AnimationUtils.loadAnimation(
              view132.getContext(), R.anim.go_prev_out));
          flipper.showPrevious();
          return;
      }
  });
  </code></pre>
