开机动画播放完进入launcher黑屏2s

当修改了开机动画的播放次数后，例如由无限循环播放改为只播放一次，开机动画播放完进入launcher黑屏几秒。

增加一句getWindow().setBackgroundDrawableResource(R.drawable.background);可以解决。
具体如下。

//vendor\mediatek\proprietary\packages\apps\MtkSettings\src\com\android\settings\FallbackHome.java
 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getWindow().setBackgroundDrawableResource(R.drawable.background);

        // Set ourselves totally black before the device is provisioned so that
        // we don't flash the wallpaper before SUW
        mProvisioned = Settings.Global.getInt(getContentResolver(),
                Settings.Global.DEVICE_PROVISIONED, 0) != 0;
        if (!mProvisioned) {
            setTheme(R.style.FallbackHome_SetupWizard);
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        } else {
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
        }

        registerReceiver(mReceiver, new IntentFilter(Intent.ACTION_USER_UNLOCKED));
        maybeFinish();
    }

background就用开机动画的最后一帧图片即可,放到setting的资源目录下。
