Federico,
I'm assuming this code is throwing the exception:
   
    mOTPApp = ((OTPApp) getActivity().getApplication());

Did you modify the OTPApp class at all?

OTPApp class must extend android.app.Application for the cast to succeed.

Thanks,
Sean

Thanks for the reply!
Yes, the problem is that the class OTPApp already extends Application.

Thanks,

Federico

Federico,
Check your AndroidManifest.xml for your project.  You’ll need something that looks like this:

<application
            android:name=".OTPApp"
            android:icon="@drawable/ic_launcher"
           android:label="@string/app_name"
            android:allowBackup="true">

With the “.” notation, the application android:name attribute assumes that the OTPApp class is in the package defined by the “package” attribute at the top of your manifest (package="edu.usf.cutr.opentripplanner.android", for main OTP project).

For example, if your main application package is “my.package”, then OTPApp.java must be in “main/java/my/package” directory in the project. 

Alternately, you can fully qualify the package in the manifest.  For example, if OTPApp is in “my.package.otherpackage”, your manifest would look like:

<application
            android:name="my.package.otherpackage.OTPApp"
            android:icon="@drawable/ic_launcher"
           android:label="@string/app_name"
            android:allowBackup="true">

If you can share how you’re using OTP Android, we’d be interested in hearing it!
