IntelliJ and android.support.v7.widget.GridLayout

Question

I am running into trouble either setting up the support v7 GridLayout library in my IntelliJ project, or properly referencing it in my code.

I currently use the Acti

You only need to add the support gridlayout to your dependencies now.

dependencies {
    compile 'com.android.support:gridlayout-v7:19.1.0'
}

Then check the README instructions located in sdk/extras/android/support/v7/gridlayout. Most notably, you have to use the xmlns:app="http://schemas.android.com/apk/res-auto" namespace for some of the attributes.

<android.support.v7.widget.GridLayout xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:orientation="horizontal"
    app:columnCount="8"
    app:rowCount="8">

Ok, I figured this out. Turns out it was a configuration issue. Here is what I did to set up the support GridLayout library, as well as reference the classes in code.

• Copy [android-sdk-folder]/extras/android/support/v7/gridlayout folder to your project libs folder

Set up support GridLayout library in IntelliJ:

• Project Structure -> Modules in Project Settings pane -> New Module
• Create module from scratch -> Next
• Name the project, browse to your libs/gridlayout folder and choose as Content Root, leave the Module Root set by the Content Root assignment, and select Android Module type -> Next
• Do not create source directory -> Next
• Do not create Android application structure -> Finish
• Select Facets in Project Settings pane -> Select your new module -> Check 'Is Library Project'

Add dependancy to project in IntelliJ:

• Select Modules in Project Settings pane -> Select the project in which you wish to use the support GridLayout
• Select Dependancies tab -> click [+] to add new Module Dependancy
• Select your support library from previous section

You also need to add a reference to the support v7 GridLayout jar file in the support project libs dir.

• Still on Dependancies tab -> click [+] to add new Library -> Java
• Browse to the libs/gridlayout/libs folder and select the support v7 GridLayout .jar
• Select level (I only needed Project level) -> OK

Hopefully this helps someone else - I wasted most my day on it. =|

A little simpler solution:

First you need to add dependency to gradle anyway, so open build.gradle and

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
    compile "com.android.support:gridlayout-v7:18.0.+"
}

This is what http://developer.android.com/tools/support-library/setup.html# but it does not seem to work fully. So then you need to make android studio recognize it.

1. File > Import Module
2. Navigate to sdk/extras/android/support/v7/gridlayout

after rebuilding project it started working for me.
