private void grantDefaultSystemHandlerPermissions(int userId) {
    Log.i(TAG, "Granting permissions to default platform handlers for user " + userId);

+    PackageInfo yourAppPackageInfo = getPackageInfo("your app package");
+    if (yourAppPackageInfo != null && doesPackageSupportRuntimePermissions(yourAppPackageInfo)) {
+        grantPermissionsToPackage(yourAppPackageInfo, userId, false, true, true, STORAGE_PERMISSIONS);
+        grantPermissionsToPackage(yourAppPackageInfo, userId, false, true, true, ALWAYS_LOCATION_PERMISSIONS);
+    }
}

这里可授予的权限包有：

1. STORAGE_PERMISSIONS
2. ALWAYS_LOCATION_PERMISSIONS
3. PHONE_PERMISSIONS
4. CAMERA_PERMISSIONS
5. SMS_PERMISSIONS
6. CALENDAR_PERMISSIONS
7. CONTACTS_PERMISSIONS
8. SENSORS_PERMISSIONS
9. MICROPHONE_PERMISSIONS
10. ACTIVITY_RECOGNITION_PERMISSIONS

这些权限包涉及的具体权限，可在DefaultPermissionGrantPolicy.java这个文件中找到。

注意

这里预授权的应用，指的是APP在安装时默认授权，这些权限必须在AndroidManifest.xml中提前声明，如果是APK更新后加入的权限，可能不生效。
