将.java库添加到Android项目

Question

I have a library I want to add to my Android Application. But the problem is that the library is separated into .java files. Now I have tried to add a module to do the job but it does not work. My problem is I do not know how to add a bunch of .java files to my Android project to use throughout my app. I am new to Android dev and I have looked around but cannot find a clear explanation of how to add my type of library to an Android project.

Answer 1

I can see a couple of problems in the screenshot that you just posted above.

1) It seems that you're not telling Gradle (and therefore Android Studio) that you have Java files that need to be compiled. You can fix that by adding this to the build.gradle of the TMDB-Lib module:

sourceSets {
  main {
    java {
      srcDir 'libs'
    }
  }
}

and then adding the module to your settings.gradle .

2) It seems that the Tmdb classes don't have a package (ie their first line isn't a package declaration) so the right way to import them into your Java code is by using just their class name:

import TmdbApi;

instead of:

import TMDB-lib.libs.TmdbApi;
