title: Application crashes because it takes too much memory?
body: <p>I am about to finish my Application and recently I encountered a problem that I can't fix.
  My application is contained of 5 layouts, and 1 activity for each layout, 5 layouts.
  Now ever since I added ads to my Application, my application stated taking enormous size on ram memory and after switching few layouts it crashes.
  My App size is 10.8mb but on phone it takes up to 75mb of Ram memory.
  Here is the warning I get from logcat: <a href="http://prntscr.com/2naqr8" rel="nofollow">http://prntscr.com/2naqr8</a>
  Here is Logcat when Application crashes: <a href="http://prntscr.com/2naret" rel="nofollow">http://prntscr.com/2naret</a>   2nd part: <a href="http://prntscr.com/2narhi" rel="nofollow">http://prntscr.com/2narhi</a> 3rd part: <a href="http://prntscr.com/2narhi" rel="nofollow">http://prntscr.com/2narhi</a></p>
  
  <p>Now my code is pretty much simple code, 1st activity is Splash screen, 2nd is menu and other 3 are same codes.
  Menu code: </p>
  
  <pre><code>package puske.com;
  import com.google.ads.AdRequest;
  import com.google.ads.AdView;
  
  import android.app.Activity;
  import android.content.Intent;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.Button;
  
  public class Menu extends Activity {
  
      @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.menu);
      AdView myAdView = (AdView)findViewById(R.id.adView);
      AdRequest adRequest = new AdRequest();
      myAdView.loadAd(adRequest);
  
  
  
  
  Button button1=(Button)findViewById(R.id.menu1);
  button1.setOnClickListener(new View.OnClickListener() {
  
      @Override
      public void onClick(View v) {
          startActivity(new Intent(Menu.this, Rifles.class));
  
          finish();
  
      }
  });
  
  
  }
  </code></pre>
  
  <p>After this it repeats2 times for other 2 activities.
  My other 3 activities are same, only difference is in resources.</p>

  <p>That's about it, whole code  I unbind all drawables, release MP and activities and still stakes too much space on Device and crashes. Anyone know what might be causing this?
  And finally here is my XML, again, it's same for all layouts except for IDS and resources</p>
