Android and Eclipse - java.lang.NoClassDefFoundError with project dependency

I'm trying to build a abstract classes in one project as a template and to implement them in another. However when trying to run an Activity that implements the template Activity, the NoClassDefFoundError pops up. I've added the template project to the Java Build Path of the other one, checked it in "Order and Export", cleaned the project, but nothing helps. I also tried to compile the project with the 1.6 compiler. All resulted with the same error. When trying to add the template project as a JAR Eclipse says there's a duplicate of Manifest files and won't allow it.

Does anyone has any idea what else I can do to fix this problem?

Here's the error log I receive:

04-05 00:29:09.941: E/AndroidRuntime(1348):     ... 14 more

And the manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="scf1984.games.testQuest"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="scf1984.games.testQuest.TestMainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="scf1984.games.testQuest.TestQuestActivity"
        android:label="@string/app_name" >

    </activity>
</application>

</manifest>

The invoking method:

    public void startTestQuest(View v) {
    Intent i = new Intent(this,
            scf1984.games.testQuest.TestQuestActivity.class);
    startActivity(i);
}

You need to mark your "template project" as an Android library project. Go to Project->Properties->Android and checked the "is library".

Intent intent = (Intent)new Intent();

intent.setClassName(package name, package name + class);

startActivity(intent);

try this

Most likely you're missing the activity declaration in the Android manifest. You should pastebin the full error and your AndroidManifest.xml
