I have built an android app, but it does not seem stable. It is a large app with various Async tasks and takes photos, encrypts, decrypts files, prints to a Bluetooth printer.

However, it sometimes randomly crashes. What is the best way to find out the issue and am i not doing something right? If i run it in debug it works fine, it only crashs now and then.

Sometimes i restart the galaxy tablet it is on and it works fine for a while again. Am i not closing something correctly? whats the best way to test and find out the issue?

Should i have these many threads running?

EDIT 3:
You also seem to get a FileNotFoundException on a text file (/mnt/sdcard/external_sd/QBics/SendQ/1_855_J7_Incidents.txt, I assume this is the CSV file you mention in your comments below). Is it guaranteed that a file is always present to parse?

EDIT 2:
I might have made a misleading point in my previous edit: According to some comments here below the internal memory in Android devices (in general?) suffer from roughly the same limitations as do the SD-cards as far as the write limit is concerned, hence, the “wear” caused by frequent writing shouldn’t be a restrictive factor when choosing where to put the database (the internal memory will be just as much worn out as the SD-card would be).

EDIT 1:
Thanks for the log output.

I see a lot of exceptions in the logs which complain about databases not being closed properly and SD-card being unmounted or not available.

Does your application write to a database? Is that database stored on the SD-card? If yes, try to move the database to the internal storage instead.

It’s usually not recommended to put databases on SD-cards while the SD-card isn’t always accessible. The SD-card is also visible to all installed apps which raises questions regarding security. And from an even wider perspective; the SD-card has a limited lifespan as far as the number of writes that can be done to the card. That number is indeed huge, but nevertheless it’s there…

ORIGIN:
I would connect the device to the development machine (through the USB cable) and issue an adb logcat in the Terminal directly after the app crashes. You will then get a log print which might show you information on what went wrong.
