I am trying to run the simplest Hello World example app and looks like I can crash it even all it does is showing a TextView.
Steps to reproduce: Launch it in the emulator (1.5). Open the app – it shows the text view, then lock the phone by pressing “end call” button. Unlock by pressing “menu”, then press “back”. App crashes with “The process android.process.acore has stopped unexpectedly…” and Force Close button. It does not happen all the time, but I am able to reproduce it every time after wiping the user data at least.
I wonder if default Hello World is missing a detail which was considered too advanced for a hello world… Such problems with a basic example does not look very encouraging =)
Any idea what detail is missing and how to avoid this crash?

sounds to me more like something wrong with your emulator. Why dont you delete your emulator and create a new one and try again with a fresh project.
Hope that will help you. BTW why are you using emulator on 1.5?? Start to build applications for min 2.1.
Good luck.
