If I saw some error message on my phone,

I want to check and learn why it pop it error.

I used comment like adb bugreport or adb logcat.

It will output some file or '.txt'.

Then how check on file or txt. because it will pop out a lot of information. how to find the error point.

I tried Ctrl + F error. it will find about 500 'error' word.

  • how do you install your app on your device? – L2_Paver Feb 05 '20 at 05:30
  • To debug your app on your physical device, you need to turn on your developer mode >> allow usb debugging then connect your phone to PC via usb – L2_Paver Feb 05 '20 at 05:31
