My app just crashed, how can I get the crash log?

Question

I am testing my app on my actual device, and it seems like there is a memory leak. The app has crashed after a couple of hours. How can I pull up the log of the crash?

I plugged my phone in via USB and tried:

adb logcat -v

but I get the following message in my terminal:

- waiting for device -
error: more than one device and emulator

How can I diagnose my crash?

Answer 1

That's because there's...

more than one device and emulator

The error is fairly clear. So, what you do in this case is:

adb devices

And it list the name of your devices/emulators. Then:

adb -s name-of-your-device logcat
