Hello,
You could use the LastException keyword and store the Message for example using a TextWriter.

Or, put your IDE in DEBUG mode. You should see some information when the app closes

no debugger shows whem there is an error in code. my app is closing suddenly and says it sttopped working. nothing in debugger

And can you catch the LastException ?

 

[tufanv]

nope didnt use it. dont know how to use it

You'll find information about http://www.b4x.com/android/help/core.html#exception

there are many subs in my app for 4000 lines i dont think i can use try catch to find the error. And it is not an error to be caught by lastexception i think. As i said it is not n error you can see in debug mode or similar. it just closes and say unfortunatly "app name" has stopped.

So the last idea I have is to connect your device via USB, activate the Developper USB Debug mode and look at the Unfiltered logs to find the Java error you produce. I can't help more
