I was only able to find logcat for native apps.
When I connected to the device with Momentics and used the target file navigator I did not find the logcat file for the Android app I am testing.
Is there any other option apart from Momentics?
I use the Eclipse IDE for Android. I have installed BB ADT because it's their option as the device explorer and DDMB do not identify BlackBerry 10 devices.
