java.lang.NoClassDefFoundError calling activity from separate application

Question

We're getting this exception when attempting to define an intent in TestDriver(Centaur-TD) to start the dataRead_Activity class in Centaur. The two applications are in separate projects.

Removed this line of code:

Intent aa = new Intent(TestDriver.this, dataRead_Activity.class);

And, inserted this one:

startActivity(new Intent("cfts.testtools.Centaur.dataRead_Activity"));

The logcat information changed to:

Step #1: Add an <intent-filter> to the second activity with a custom action:

<intent-filter>
  <action android:name="com.testapp.ws.XYZ"/>
  <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Step #2: Start that activity using an appropriate Intent:

startActivity(new Intent("com.testapp.ws.XYZ"));

I made the changes and got "android.content.ActivityNotFoundException: No Activity found to handle Intent { act=cfts.testtools.Centaur.dataRead_Activity }" when starting the dataRead_Activity. – user2584082 Aug 27 '13 at 21:04
` ` Here you use $ and in Intent call `startActivity(new Intent("cfts.testtools.Centaur.dataRead_Activity"));` you use a `.` – Rachit Mishra Aug 27 '13 at 21:10
