定制九：去掉第三方应用的申请权限弹窗

比如我的 App 需要 Camera 和 Recorder 权限:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

frameworks/base/services/core/java/com/android/server/pm/DefaultPermissionGrantPolicy.java
是用来控制 App 权限的.
在其中添加系统 APP 所带权限, 第一次开机后就会将该权限赋予 App.

       PackageParser.Package  AiiagePackage = getPackageLPr(
               "com.android.Aiiage");
       if (AiiagePackage != null) {
Log.d(TAG, "AiiagePackage >> not null");
           grantRuntimePermissionsLPw(AiiagePackage, CAMERA_PERMISSIONS, userId);
           grantRuntimePermissionsLPw(AiiagePackage, MICROPHONE_PERMISSIONS, userId);
       }else{
           Log.d(TAG, "AiiagePackage >> null");
       }
