Question

hello fellow android programmers,
I’m constantly running into the same problem over and over again and I can’t figure it out, so I thought I’d ask my question here.

To implement ACRA (Application Crash Reporting for Android @ http://code.google.com/p/acra) I have to create a subclass of android.Application and instantiate ACRA.

I create this subclass from within the Manifest.xml editor by clicking on the left upper field “Name” in the “Application” tab. A window pops up where I’m asked to give a proper name to the new class and it is created in the /gen folder (only the R.java is also in this folder) and the needed attribute android:name is set in the <application/> tag automatically.

This works like a charm and all is good if I run my application from within the IDE on the emulator or on my debugging device… BUT, as soon as I want to export the whole package (doesn’t mind if “signed” or “unsigned”) the previous created android.Application subclass is removed from the /gen folder (must be from compiling), the APK gets saved and no error shows up. Until one tries to install and run the application – this will fail due to the lack of this unlucky subclass…

What is wrong? Where do I have to place this subclass other then in the /gen folder? Does anybody else run into the same problem?

Answer 1

It should not go into the /gen directory; that directory is for code that is automatically generated by the Android compiler during builds. The Application class you’re creating is application code, not auto-generated code. Don’t be confused by the fact that ADT is doing you a favor by “generating” it for you from the GUI editor; that’s not the same thing as the compiler building the code automatically for every build.

Your Application class should go in the same place as all your other app code (Activity subclasses, etc), namely /src (or /source or whatever depending on how you set up your project).
