问题
i know this question has been asked several times. but i had to find out that it was a long time ago and there were no solutions.
so my question:
i have a big project "A", for this project i have made and tested a subproject "a" in a separate app. Now I want to bring these projects together or rather inform, project "a" in "A".
what's the best approach?
回答1:
You can import your second project as a Gradle Project to your first Android Studio Project.
You can import project via:
1.a. From Project view, click right click your project root and follow New/Module.
1.b. And then, choose "Import Gradle Project".
1.c. Select your second project's module root.
2. You can follow File/New/New Module and same as 1.b.
3. You can follow File/New/Import Module and same as 1.c.
When you imported existing Gradle Project, you can see it on the configurations drop-down menu. You can run, debug or even compile for release them separately.
