わからない問題があります。次のコード スニペットに到達したとき

public class MatchViewActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.d("OnCreate in MatchViewActivity","1");
        setContentView(R.layout.activity_match_view); <--- Crash occurrs here
        Log.d("","2");
        Intent intent = getIntent();

シミュレーターで常に次のエラーが発生します。

10-07 18:41:39.012: E/dalvikvm-heap(1099): Out of memory on a 3686416-byte allocation.

私が見つけることができるlogcatのさらに下のいくつかの行：

「activity_match_view」が存在することを確認しました。ここで何が起きてるの？

対応するレイアウト ファイル:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/main_background" >

    <ListView
        android:id="@+id/matchView_ListView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:cacheColorHint="#00000000">
    </ListView>

</FrameLayout>

背景画像には .png 画像の代わりに .jpeg/.jpg 形式を使用してください。これは、Android でリソースを再作成する際に .png が .jpeg/.jpg 画像と比較してより多くのヒープ メモリを消費するためです。
