Add support to andorid projects

[EsanLe]

An normal android projec directory structure like this:

</MyApplication/
▸ .gradle/
▸ .idea/
▾ app/
  ▸ build/
  ▸ libs/
  ▾ src/
    ▸ androidTest/
    ▾ main/
      ▾ java/com/example/myapplication/
          MainActivity.java
      ▸ res/
        AndroidManifest.xml
    ▸ test/java/com/example/myapplication/
    .gitignore
    app.iml
    build.gradle
    proguard-rules.pro
▸ build/
...

But when I open a .java inside app in vim, intellij will open app/ as a project and create app/.idea and other intellij related files

</IdeaProjects/MyApplication/
▸ .gradle/
▸ .idea/
▾ app/
  ▸ .idea/
  ▸ build/
  ▸ libs/
  ▾ src/
    ▸ androidTest/
    ▾ main/
      ▾ java/com/example/eiddle/myapplication/
          MainActivity.java
      ▸ res/
        AndroidManifest.xml
    ▸ test/
    .gitignore
    app.iml
    build.gradle
    proguard-rules.pro
▸ build/
▸ gradle/
  .gitignore

Both android-studio and intellij-ce have the same issue
