Android application process gets killed automatically after running for some time

My android application gets killed automatically after running for some time (1 hour), this is the log that gets printed to the console when the process dies. Process <package name> (PID 21659) has died, and there are other services killed before my application gets killed which are not related to my application. Is this because of the not enough CPU resources available?

Do you by any change use PackageManager object?
I've had the same issue and it turned out there's a weird bug using this object, if you are using it too much it may "die" and cause your app to also receive a "dead object exception".
If not, I'd recommend you try to comment out lines that you might have added prior to this exception and try to figure out what is causing that issue.
Also, if it's possible to provide us with code, that would help

Dan Baruch, thanks for the reply. I found that there is a memory leak in my JNI code, which is why android is killing my services and application. And the weird part is that the memory leak is happening very slowly and there are no logs which say this happens because of out of memory
