AndEngine - unable to complete operation

I am new to Android development and am having trouble using AndEngine. I try to run an empty application, but I get a runtime error like this:

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 with no luck. However, when I expanded TestAppActivity from Activity instead of BaseGameActivity, it worked.

Any help is appreciated, Sami

Unable to resolve superclass of Lcom/MyApps/TestApp/TestAppActivity and that it works when you inherit from Activity , assume that you do not include the AndEngine library in your APK - therefore, BaseGameActivity cannot be found at runtime.

Make sure the AndEngine dependency is in your libs directory in your Android project; not just added to your path to Eclipse.

In fact, if you have the latest Android Eclipse plugin, any dependencies will be automatically included in your APK if you just put them in libs .

I got an error message with an error, and the problem was that I installed the wrong version of JDK, when I downloaded and installed JDK6 instead of 7, it worked fine. If this saves anyone from the nightmare that I just experienced, I will leave it here.
