How to add a linked source folder in Android Studio

Question

In Eclipse I can add a source folder to my android project as a  linked source folder   How do I achieve the same thing in Android Studio    Or is it possible to add a external folder to build in gradle

in your build gradle add the following to the end of the android node  android                          sourceSets           main java srcDirs     src main  lt YOUR DIRECTORY gt

While sourceSets allows you to include entire directory structures  there s no way to exclude parts of it in Android Studio  as of version 1 2   as described here  Android Studio Exclude Class from build   Until Android Studio gets updated to support include exclude directives for Android sources  Symlinks work quite well   If you re using Windows  native tools such as junction or mklink can accomplish the equivalent of Un x symlinks   CygWin can also create these with a little coersion   See  Git Symlinks in Windows and How to make symbolic link with cygwin in Windows 7

Just in case anyone is interested  heres a complete Java module gradle file that correctly generates and references the built artefacts within an Android multi module application  buildscript       repositories           maven               url  https   plugins gradle org m2                       dependencies           classpath  net ltgt gradle gradle-apt-plugin 0 15           apply plugin   net ltgt apt  apply plugin   java-library  apply plugin   idea   idea       module           sourceDirs    file   buildDir generated source apt main           testSourceDirs    file   buildDir generated source apt test            dependencies           Dagger 2 and Compiler     compile  com google dagger dagger 2 15      apt  com google dagger dagger-compiler 2 15      compile  com google guava guava 24 1-jre      sourceCompatibility    1 8  targetCompatibility    1 8

If you re not using gradle  creating a project from an APK  for instance   this can be done through the Android Studio UI  as of version 3 3 2     Right-click the project root directory  pick Open Module Settings Hit the   Add Content Root button  center right  Add your path and hit OK   In my experience  with native code   as long as your  so s are built with debug symbols and from the same absolute paths  breakpoints added in source files will be automatically recognized

The right answer is   android                          sourceSets           main java srcDirs     src main  lt YOUR DIRECTORY gt             Furthermore  if your external source directory is not under src main  you could use a relative path like this   sourceSets       main java srcDirs     src main           lt YOUR DIRECTORY gt

You can add a source folder to the build script and then sync   Look for sourceSets in the documentation here   http   tools android com tech-docs new-build-system user-guide TOC-Basic-Project  I haven t found a good way of adding test source folders   I have manually added the source to the  iml file   Of course this means it will go away everytime the build script is synched
