AOSP and IntelliJ IDEA

Question

Has anyone tried to work with AOSP using IntelliJ IDEA? I see in Android sources a specific folder (development/ide/intellij) but I cannot find any information how to use it

Answer 1

Official instructions can be found by going to development/tools/idegen path and checking the README file. It's a good idea to read it yourself. This is the content for IntelliJ:

If you're using IntelliJ...

If this is your first time using IDEGen...

  IDEA needs a lot of memory. Add "-Xms748m -Xmx748m" to your VM options
  in "IDEA_HOME/bin/idea.vmoptions" on Linux or
  "IntelliJ IDEA.app/Contents/Info.plist" on OS X.

  Create a JDK configuration named "1.6 (No Libraries)" by adding a new
  JDK like you normally would and then removing all of the jar entries
  under the "Classpath" tab. This will ensure that you only get access to
  Android's core libraries and not those from your desktop VM.

From the project's root directory...

   Repeat these steps after each sync...

  1) make (to produce generated .java source)
  2) development/tools/idegen/idegen.sh
  3) Open android.ipr in IntelliJ. If you already have the project open,
     hit the sync button in IntelliJ, and it will automatically detect the
     updated configuration.

  If you get unexpected compilation errors from IntelliJ, try running
  "Build -> Rebuild Project". Sometimes IntelliJ gets confused after the
  project changes significantly.

The following error message might pop up when following the instructions.

Couldn't find idegen.jar. Please run make first.
