calling a mapactivity from another activity

Question

I get a class not found exception.

I have included the required entry in manifest file. The code in current activity is as follows:

 Intent i = new Intent(MainListingA.this, DrawTheatreMap.class);

            try{
             startActivity(i); 

            }

........

The error I get is as follows:

07-26 23:03:20.259: WARN/dalvikvm(307): threadid=1: thread exiting with uncaught exception (group=0x4001d800)

Any help is highly appreciated.

On a standalone basis, the same map activity works fine.

Answer 1

I usually encounter that error when the application is being run on an emulator that lacks the Google APIs, because Android cannot find the MapActivity class.

Answer 2

You might have the -Tag in the wrong place, at least that was my problem once and the Eclipse / the Google SDK does not complain about that. It has to be under , different to uses-permission which goes beside the application-Tag.

It should look like this:

<manifest ...>

    <uses-permission android:name="android.permission.INTERNET" />

    <application ...>

        <uses-library android:name="com.google.android.maps" />

    </application>

</manifest>
