Long package name build error in Android Studio

Question

The package name of my app is very long:

app.running.com.voice.and.service.song.backup.audio.run.inthe.background

This is a B2B project and I can't reduce their package name now as it is already fixed.

Error:failed writing to 'D:\Google_Play\Android Studio\IndWork\Sound\Sound\app\build\generated\source\r\androidTest\debug\app\running\com\voice\and\service\song\backup\audio\run\inthe\background\test\R.java':

The system cannot find the file specified. (2).

I think there has to be a solution for this problem. Pls guide.

What makes you think the error is caused by the package name length? — sdabet, Feb 25 '18 at 15:51
Because that error has the full path as per the package name, I mean folders as per package names. — Piyush-Ask Any Difference, Feb 25 '18 at 15:52
Yes but the error message doesn't state that the path is too long, just that it cannot find it. — sdabet, Feb 25 '18 at 15:58
When I reduce the length of the package name then Build is successful — Piyush-Ask Any Difference, Feb 26 '18 at 06:58
Well, your could move the project outside of `Google_Play\Android Studio`. Or build it in Linux, where there is less of a restriction on path length — OneCricketeer, Mar 08 '18 at 14:41

package name don't have anything wrong with it as far as i know
as log say's error is at \build\generated my first suggestion is to clean project with command

$ gradlew clean

at root of your project if it's unable to clean delete manually

android/build
android/app/build

don't worry the are generated files . then type in root of project

$ gradlew build

be sure your connected to internet to get needed lib from maven or etc.
