API level 3 (Cupcake) or later.

1. Install Maven (http://maven.apache.org/)
2. Install android-sdks into local m2 repository using https://github.com/mosabua/maven-android-sdk-deployer    
3. Clone the repository

    $ git clone https://github.com/esmasui/AndroidJUnit4.git AndroidJUnit4-readonly

4. Build libraries
    
    $ cd AndroidJUnit4-readonly
    $ mvn eclipse:eclipse install

5. Import AndroidJunit4-readonly/android-junit4 as a Android library project or jar file to your Android test project.

<dependency>
	<groupId>com.uphyca</groupId>
	<artifactId>android-junit4</artifactId>
	<version>(insert latest version)</version>
</dependency>

<plugin>
	<groupId>com.jayway.maven.plugins.android.generation2</groupId>
	<artifactId>android-maven-plugin</artifactId>
	<configuration>
		...
		<test>
			<skip>false</skip>
		</test>
	</configuration>

</plugin>

$ mvn clean install -Dandroid.test.skip=false

1. Set com.uphyca.testing.JUnit4InstrumentationTestRunner into instrumentation in your AndroidManifest.xml

    <instrumentation
        android:name="com.uphyca.testing.JUnit4InstrumentationTestRunner"
        android:targetPackage="your.test.package" />

2. Write your test classes that extends base test classes for Android dependent tests.

    The base test classses located in com.uphyca.testing package as same name of original android.test package's classes.
    For example; JUnit4 version of android.test.ActivityUnitTestCase is com.uphyca.testing.ActivityUnitTestCase.

Supported test classes are
    AndroidTestCase
    InstrumentationTestCase
    ActivityInstrumentationTestCase<T extends Activity>
    ActivityInstrumentationTestCase2<T extends Activity>
    ActivityTestCase, ActivityUnitTestCase<T extends Activity>
    ApplicationTestCase<T extends Application>
    LoaderTestCase
    ProviderTestCase<T extends ContentProvider>
    ProviderTestCase2<T extends ContentProvider>
    ServiceTestCase<T extends Service>
    SingleLaunchActivityTestCase<T extends Activity>
    SyncBaseInstrumentation
