How do I add a library (android-support-v7-appcompat) in IntelliJ IDEA

Question

I created a project, copied the resource files in the project, library, added it to the project structure, prescribed style Theme.AppCompat. Compiled without errors, but when you start the relegation Exception:

08-03 00:50:00.406: ERROR/AndroidRuntime(4055): FATAL EXCEPTION: main         java.lang.NoClassDefFoundError: android.support.v7.appcompat.R$styleable         at android.support.v7.app.ActionBarActivityDelegate.onCreate(ActionBarActivityDelegate.java:98)         at android.support.v7.app.ActionBarActivityDelegateICS.onCreate(ActionBarActivityDelegateICS.java:58)         at android.support.v7.app.ActionBarActivity.onCreate(ActionBarActivity.java:98)         at com.example.SampleMetrRost.CentralActivity.onCreate(CentralActivity.java:12)         at android.app.Activity.performCreate(Activity.java:4636)         at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1051)         at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1924)         at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1985)         at android.app.ActivityThread.access$600(ActivityThread.java:127)         at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1151)         at android.os.Handler.dispatchMessage(Handler.java:99)         at android.os.Looper.loop(Looper.java:137)         at android.app.ActivityThread.main(ActivityThread.java:4476)         at java.lang.reflect.Method.invokeNative(Native Method)         at java.lang.reflect.Method.invoke(Method.java:511)         at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:816)         at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:583)         at dalvik.system.NativeStart.main(Native Method) 

Help me, please. Spent all day today.

Answer 1

Using Gradle

If you are using Gradle, you can add it as a compile dependency.

Instructions

1. Make sure you have the Android Support Repository SDK package installed. Android Studio automatically recognizes this repository during the build process (not sure about plain IntelliJ).

   

2. Add the dependency to {project}/build.gradle

   dependencies {     compile 'com.android.support:appcompat-v7:+' } 

3. Click the Sync Project with Gradle Files button.

EDIT: Looks like these same instructions are on the documentation under Adding libraries with resources -> Using Android Studio.

Answer 2

Without Gradle (Click here for the Gradle solution)

1. Create a support library project.

2. Import your library project to Intellij from Eclipse project (this step only applies if you created your library in Eclipse).

3. Right click on module and choose Open Module Settings.

4. Setup libraries of v7 jar file

5. Setup library module of v7

6. Setup app module dependency of v7 library module
