I am new to Android development and facing a problem while using AndEngine. I am trying to run an empty application but getting a runtime error as follows:

The used manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.MyApps.TestApp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".TestAppActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I tried putting the whole package name instead of .TestAppActivity but without any luck.
However when I extended TestAppActivity from Activity instead of BaseGameActivity it worked.
Any help is appreciated,
Sami
The error
Unable to resolve superclass of Lcom/MyApps/TestApp/TestAppActivityand that it works when you inherit fromActivitywould suggest that you’re not including the AndEngine library in your APK — therefore at runtimeBaseGameActivitycannot be found.Make sure the AndEngine dependency is in your
libsdirectory in your Android project; not just added to your Eclipse classpath.In fact, if you have the latest Android Eclipse plugin, any dependencies will be automatically included in your APK if you just place them in
libs.
