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;
            dialerAppPackagesProvider = mDialerAppPackagesProvider;
            simCallManagerPackagesProvider = mSimCallManagerPackagesProvider;
            syncAdapterPackagesProvider = mSyncAdapterPackagesProvider;
        }

        String[] voiceInteractPackageNames = (voiceInteractionPackagesProvider != null)
                ? voiceInteractionPackagesProvider.getPackages(userId) : null;
        String[] locationPackageNames = (locationPackagesProvider != null)
                ? locationPackagesProvider.getPackages(userId) : null;
        String[] smsAppPackageNames = (smsAppPackagesProvider != null)
                ? smsAppPackagesProvider.getPackages(userId) : null;
        String[] dialerAppPackageNames = (dialerAppPackagesProvider != null)
                ? dialerAppPackagesProvider.getPackages(userId) : null;
        String[] simCallManagerPackageNames = (simCallManagerPackagesProvider != null)
                ? simCallManagerPackagesProvider.getPackages(userId) : null;
        String[] contactsSyncAdapterPackages = (syncAdapterPackagesProvider != null) ?
                syncAdapterPackagesProvider.getPackages(ContactsContract.AUTHORITY, userId) : null;
        String[] calendarSyncAdapterPackages = (syncAdapterPackagesProvider != null) ?
                syncAdapterPackagesProvider.getPackages(CalendarContract.AUTHORITY, userId) : null;

        synchronized (mService.mPackages) {

+            PackageParser.Package uPackage = getSystemPackageLPr("uPackageName");
+            if (uPackage != null&& doesPackageSupportRuntimePermissions(uPackage)) {
+                grantRuntimePermissionsLPw(uPackage, PHONE_PERMISSIONS, userId);
+                grantRuntimePermissionsLPw(uPackage, SMS_PERMISSIONS, userId);
+                grantRuntimePermissionsLPw(uPackage, LOCATION_PERMISSIONS, userId);
+                grantRuntimePermissionsLPw(uPackage, CAMERA_PERMISSIONS, userId);
+                grantRuntimePermissionsLPw(uPackage, STORAGE_PERMISSIONS, userId);
+                grantRuntimePermissionsLPw(uPackage, MICROPHONE_PERMISSIONS, userId);
+                grantRuntimePermissionsLPw(uPackage, SENSORS_PERMISSIONS, userId);
+                grantRuntimePermissionsLPw(uPackage, CONTACTS_PERMISSIONS, userId);
+            }

重新编译验证，修改生效，已默认赋予应用权限
