在主屏的設置墻紙界面，由于墻紙圖片太大，瀏覽墻紙大圖的預覽圖時，產生了OOM錯誤。

異常提示：

E/InputManagerService(  177): Got RemoteException sending setActive(false) notification

代碼部分：

public class com.android.launcher.WallpaperChooser

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        findWallpapers();

        setContentView(R.layout.wallpaper_chooser);

        mOptions = new BitmapFactory.Options();
        mOptions.inDither = false;
        mOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
        mOptions.inSampleSize = 2;// fix it
... ...

    public void onItemSelected(AdapterView parent, View v, int position, long id) {
        final ImageView view = mImageView;
        Bitmap b = BitmapFactory.decodeResource(getResources(), IMAGE_IDS[position], mOptions);// here throw the OOMError

... ...

解決方法：

1、調整merory useage

mOptions.inSampleSize = 2;//return an image that is 1/2 the width/height of the original, and 1/4 the number of pixels.

2、調整bitmap size

bitmap = Bitmap.createScaledBitmap(bitmap, 100, 150, false);

3、調整temp storage

mOptions.inSampleSize = new byte[100 * 1024];
