framework/base/services/core/java/com/android/server/pm/DefaultPermissionGrantPolicy.java
在grantDefaultSystemHandlerPermissions 方法中添加
 

			//com.qingniu.sharescale.production
			String productionPkgStr = "com.qingniu.sharescale.production"; //应用包名
			PackageParser.Package productionPkg = getPackageLPr(productionPkgStr);
			if(productionPkg!=null){ //应用需要添加的权限
				grantRuntimePermissionsLPw(productionPkg, PHONE_PERMISSIONS, userId);
				grantRuntimePermissionsLPw(productionPkg, STORAGE_PERMISSIONS, userId);
				grantRuntimePermissionsLPw(productionPkg, LOCATION_PERMISSIONS, userId);
				grantRuntimePermissionsLPw(productionPkg, CAMERA_PERMISSIONS, userId);
				grantRuntimePermissionsLPw(productionPkg, MICROPHONE_PERMISSIONS, userId);
			}
			
			//com.qingniu.majorscale
			String majorscalePkgStr = "com.qingniu.majorscale";
			PackageParser.Package majorscalePkg = getPackageLPr(majorscalePkgStr);
			if(majorscalePkg!=null){
				grantRuntimePermissionsLPw(majorscalePkg, PHONE_PERMISSIONS, userId);
				grantRuntimePermissionsLPw(majorscalePkg, STORAGE_PERMISSIONS, userId);
				grantRuntimePermissionsLPw(majorscalePkg, LOCATION_PERMISSIONS, userId);
