1、開啟 frameworks/base/core/java/android/content/pm/parsing/component/ParsedActivityUtils.java 檔案，定位到 parseActivityOrReceiver 方法的 int screenOrientation = sa.getInt(R.styleable.AndroidManifestActivity_screenOrientation, SCREEN_ORIENTATION_UNSPECIFIED); 這一行，註釋掉該行並新增如下程式碼：

// int screenOrientation = sa.getInt(R.styleable.AndroidManifestActivity_screenOrientation, SCREEN_ORIENTATION_UNSPECIFIED);
// Edit by jgduan
int screenOrientation;
if(pkg.getSharedUserId() == null){
screenOrientation = 0;
} else {
screenOrientation = sa.getInt(R.styleable.AndroidManifestActivity_screenOrientation, SCREEN_ORIENTATION_UNSPECIFIED);
}
// End

2、開啟 frameworks/base/core/java/android/app/Activity.java 檔案，對 setRequestedOrientation 方法進行如下修改：

    /**
     * Change the desired orientation of this activity. If the activity
     * is currently in the foreground or otherwise impacting the screen
     * orientation, the screen will immediately be changed (possibly causing
     * the activity to be restarted). Otherwise, this will be used the next
     * time the activity is visible.
     *
     * @param requestedOrientation An orientation constant as used in
     * {@link ActivityInfo#screenOrientation ActivityInfo.screenOrientation}.
     */
    public void setRequestedOrientation(@ActivityInfo.ScreenOrientation int requestedOrientation) {
        if (mParent == null) {
            try {
                // Edit by jgduan
                //ActivityTaskManager.getService().setRequestedOrientation(
                //        mToken, requestedOrientation);
                if(mApplication != null && mApplication.getApplicationInfo() != null
                    && mApplication.getApplicationInfo().uid > 10000){
                    ActivityTaskManager.getService().setRequestedOrientation(
                            mToken, ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                } else {
                    ActivityTaskManager.getService().setRequestedOrientation(
                            mToken, requestedOrientation);
                }
                // End
            } catch (RemoteException e) {
                // Empty
            }
        } else {
            // Edit by jgduan
            // mParent.setRequestedOrientation(requestedOrientation);
            if(mApplication != null && mApplication.getApplicationInfo() != null
                    && mApplication.getApplicationInfo().uid > 10000){
                mParent.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            }else{
                mParent.setRequestedOrientation(requestedOrientation);
            }
            // End
        }
    }
