HelloWorld Crashes on 2.2
« on: May 24, 2011, 09:06:09 pm »
So I have been trying to get the hang of JPCT-AE. So I sit down to do the HelloWorld Example. When I launch it from my own interpretation of the code it crashes so I figure must be my fault. But to check I decided to Copy and Paste the code right from the wiki. It crashes .

The Console reads:
Quote

[2011-05-24 14:02:19 - HelloWorld] Android Launch!
[2011-05-24 14:02:19 - HelloWorld] adb is running normally.
[2011-05-24 14:02:19 - HelloWorld] Performing com.threed.jpct.example.helloworld activity launch

[2011-05-24 14:02:19 - HelloWorld] Device API version is 8 (Android 2.2)
[2011-05-24 14:02:24 - HelloWorld] Application already deployed. No need to reinstall.
[2011-05-24 14:02:24 - HelloWorld] Starting activity com.threed.jpct.example.helloworld on device emulator-5554
[2011-05-24 14:02:27 - HelloWorld] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.threed.jpct.example/.helloworld }

The error message  is a tipical "process com.threed.jpct.example has stopped."

Any idea what is going wrong?

Here has to be some exception in the log. Switch to DDMS inside Eclipse to see it.

I don't know how to specifically check DDMS I will be looking that up to see what the issue is.

Could I somehow not be invoking the JPCT-AE Library the proper way?

It says that it can't find the helloworld.class in the APK. If you've copied the source code from the wiki, the class should actually be called HelloWorld. Check your AndroidManifest.xml to see, if the correct name is in there (upper-/lowercase matters).
