i believe solution problem this:

just add line application in manifest file:

android:largeheap="true" 

so manifest file should application should this:

<application         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:largeheap="true"         android:theme="@android:style/theme.light.notitlebar.fullscreen" >          <activity             android:name=".mainactivity"             android:label="@string/app_name"             android:theme="@android:style/theme.light.notitlebar.fullscreen" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity> </application>
