I want to reduce Android Studio project size to save it for after use

In MS Visual Studio, we can delete *.ipch, *.sdf and Debug files to reduce the project size

I see app/build/intermediates folder is really large, can I delete this folder?

  • Do you mean reducing the size of the project on your hard drive or reduze the size of the outcome apk file? Commented Aug 9, 2015 at 8:10

Yes, you can safely delete the intermediates folder. You can even delete the whole build folder that contains intermediates. The build folder and it's contents will be re-generated the next time you run/build your project though.

In Android Studio, go to the Terminal window. If you did not go to a different directory since you opened the IDE, you should find yourself on the top level of your project folder (something like ../Android Studio/projectname). There you simply type

./gradlew clean

That's it. I just reduced my project folder size from 589 MB to 21 MB.

thanks a lot.. this command work great. project size reduced to 1:10
You have to have priviledges to execute the gradlew file, under Ubuntu, for example: sudo chmod u+x gradlew.

The file .gitignore containted in the project created by AndroidStudio lists all files / patterns not to be stored in the git repository, i.e. those files that are not required for building the project. Therefore, it should be safe to remove all files / directories matching the patterns listed in the .gitignore file.

In my projects it lists:

*.iml
.gradle
/local.properties
/.idea/workspace.xml
/.idea/libraries
.DS_Store
/build
/captures
.externalNativeBuild

Makes TOTAL sense. It might not guarantee total cleanup, but rather maximum safe cleanup using filters. While not using automated routines might sound as a drawback, it is reassuring because user has total control of all performed acts. Will benchmark against other proposèd solutions.

Please find the batch file I use to do that. Set the batch under the root of your project directories. Hoping it helps.

I used your code, at first I got the error "“Please select Android SDK" when executing the new exported code in the emulator but I solve it with this answer stackoverflow.com/a/49568712/1363087 By the way, the app changed from 400Mb to 20Mb. Great to store in DropBox. After rebuilding it went up to 80Mb. Thanks
By the way, it also makes you select the Keys to build the apks. Is there an option to not delete something so these 2 issues are gone? I don't mind if the exported file is a bit larger. I need to use your batch file many times, but I would prefer to not have to do those 2 issues each time. Thanks
