gridview xml

<gridview     android:id="@+id/essentials_gridview"     android:layout_width="fill_parent"     android:layout_height="match_parent"     android:gravity="center"     android:horizontalspacing="10dp"     android:verticalspacing="10dp"     android:listselector="@android:color/transparent"     android:numcolumns="3"     android:padding="10dp"     android:stretchmode="columnwidth" /> 

gridview item layout

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="125dp" >      <imageview         android:id="@+list/grid_item_image_image"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:scaletype="centercrop" />"      <textview         android:id="@+list/grid_item_image_text"         android:layout_width="fill_parent"         android:layout_height="30dp"         android:layout_alignparentbottom="true"         android:gravity="center"         android:textsize="20sp"         android:textcolor="#ffffff"         android:background="#50000000"         android:singleline="true"         android:ellipsize="end" />  </relativelayout> 

the error is:

08-10 10:09:42.060: e/dalvikvm-heap(18982): out of memory on 9023376-byte allocation. 

this happens when i'm moving , forth between level 1 , level 2 activities. after couple of times, crashes error.

seems have memory leak, suggest watch session:

google i/o 2011: memory management android apps

in own experience, recommend implement viewholder pattern inside gridview's adapters.
