AndroidAOSP定制之关闭某些app的通知
前言：
最近在做AOSP系统定制时发现gms定制好了后，Google应用商店用不了，提示此设备未获得Play保护机制认证，Google应用和服务无法在此设备上运行,查看官方文档和资料，说是由于Android设备id生成不对引起的，可以通过修改系统属性解决，需求简单描述还是如何默认关闭掉Google Play服务的通知，或者某个app的通知.
1.报错信息如下：
2.解决方法1：
- 源码路径：/frameworks/base/services/core/java/com/android/server/notification/NotificationManagerService.java
- 源码：
- 通过包名判断过滤过需要关闭通知的应用

4.解决方法2：
- 源码路径：/frameworks/base/services/core/java/com/android/server/wm/AlertWindowNotification.java
- 源码：
void post() {
// We can't create/post the notification while the window manager lock is held since it will
// end up calling into activity manager. So, we post a message to do it later.
mService.mH.post(this::onPostNotification);
}
- 修改后的源码：
void post() {
// We can't create/post the notification while the window manager lock is held since it will
// end up calling into activity manager. So, we post a message to do it later.
if(mPackageName.contains("com.google.android.gms") || mPackageName.contains("com.android.vending")){
}else {
mService.mH.post(this::onPostNotification);
}
}
5.实现效果截图：
6.总结：
可以看到上面的图片已经去掉了GMS默认的通知，重启模拟器和手机，打开gms通知栏都没有提示了，这样优化了体验，不让用户一直在看到一个警告提示.今天的AOSP定制就算完成了，后面讲解如何定制输入法及GMS等等.
