Android 8.1 默认赋予应用权限

最近接到项目需求，需要默认授予预置APP的应用权限以便操作使用，具体修改参照如下：

/frameworks/base/services/core/java/com/android/server/pm/DefaultPermissionGrantPolicy.java

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

        final PackagesProvider locationPackagesProvider;
        final PackagesProvider voiceInteractionPackagesProvider;
        final PackagesProvider smsAppPackagesProvider;
        final PackagesProvider dialerAppPackagesProvider;
        final PackagesProvider simCallManagerPackagesProvider;
        final SyncAdapterPackagesProvider syncAdapterPackagesProvider;

        synchronized (mService.mPackages) {
            locationPackagesProvider = mLocationPackagesProvider;
            voiceInteractionPackagesProvider = mVoiceInteractionPackagesProvider;
            smsAppPackagesProvider = mSmsAppPackagesProvider;
