Please check the confirmation dialog on your device

Question

I am trying to connect adb device and it showing \"Please check the confirmation dialog on your device\" ..but there is no adb confirmation(rssi) dialog.

Answer 1

For me, selecting the Revoke USB debugging authorizations would crash the entire Settings app. Here's a simple method that worked for me (I had root access to the device):

The method is to simply copy your machine's adbkey.pub from the ~/.android/ directory, and put it into the Android device's sdcard (using Web or MTP) named as adb_keys, then copy the file into the correct path:

# On the problematic device
cp /sdcard/adbkey.pub /data/misc/adb/adb_keys

(Note: there's a similar answer on SO that goes into further details for this method.)

I have explained a bit more about this here, if anyone's interested.
