Nativescript Android keeps crashing - nativescript

Question

I am creating a nativescript application and when I try to debug on my android device (connected via usb) the app opens the splash screen and immediately crashes without any errors shown in the console.
I open another terminal and use adb logcat *:W --pid=15820 to get error output (warnings and above) and all I see is failures to connect. These occur after the app crashes and keep repeating every second. What else can I do to find out why my app is crashing? It runs fine on an ios emulator.

Looking through logcat in Android Studio gave me some addition error output:

Answer 1

I think you had modified
<application
android:name="com.tns.NativeScriptApplication"
to
<application
android:name="com.mycompany.myapp"
You may do it only if you are extending your own custom application class.
