Android studio Emulator ( device unauthorized)

Question

I know that on a normal device I have to authorize the debugging process, but Authorizing it on an emulator is my first time.

I just installed my first emulator on my ho

Answer 1

Just delete the ~/.android folder.

Answer 2

Issue Resolved.

Step 1- Made a new emulator(Any). Step 2- then fixed another problem the black screen by changing the settings to use hardware graphics.(Dunno if this problem was related to the bug)

And Bam every thing worked.

Answer 3

I also face the same issue and its generated because I copied my SDK from one PC to another PC with Same configuration(Software and Hardware). Now I create an emulator on Pie and also tried Oreo but unauthorised comes for both.

Solution: I delete my build tools, platform tools, emulator only not complete SDK and download all of them again. Now I create my emulator for all type of Version and now no unauthorised error for all type of emulators.

Answer 4

I found a mismatch between the .android/adbkey* files associated with the user running the process running adbd, and the same file associated with the user running the emulator.

I don't know about windows, but this is possible in Linux if you run adb as root to work around file permissions.

Fix: As the user running the emulator, type this into a command shell:

adb kill-server; adb devices
