このコードは私のICSデバイスで機能します：私はいくつかの呼び出しに敏感なサービスを使用しています。そのうちの1つはSET_PREFERRED_LAUNCHERと呼ばれ、新しいデフォルトのランチャーパッケージ（PREFERRED_PACKAGE_KEY）とそのアクティビティ（PREFERRED_ACTIVITY_KEY）をバンドルに入れます

マニフェストファイルに次の権限を追加することを忘れないでください。
<uses-permission android:name="android.permission.SET_PREFERRED_APPLICATIONS"/>
使用法：
public void setPreferredLauncher(String activity_name,String package_name)
{
Intent intent = new Intent(UPDATER_SERVICE_ACTION);
intent.putExtra(REQUEST_KEY, SET_PREFERRED_LAUNCHER);
intent.putExtra(PREFERRED_ACTIVITY_KEY, activity_name);
intent.putExtra(PREFERRED_PACKAGE_KEY, package_name);
context.startService(intent);
}
