RK3568开发平台Android 11强制所有应用横屏展示

Android 11强制所有应用横屏展示

1、打开

frameworks/base/core/java/android/content/pm/parsing/component/ParsedActivityUtils.java

文件，定位到

parseActivityOrReceiver

方法的

int screenOrientation = sa.getInt(R.styleable.AndroidManifestActivity_screenOrientation, SCREEN_ORIENTATION_UNSPECIFIED);

这一行，注释掉该行并添加如下代码：// 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、

打开

frameworks/base/core/java/android/app/Activity.java

文件，对

setRequestedOrientation

方法进行如下修改：

    /**            

     * 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            

        }            

    }
