Before I did what I am going to explain everything worked fine.
I needed to get my app SHA1 and I followed the instructions of this post:
SHA-1 fingerprint of keystore certificate
Specifically I:
- Clicked on the "Gradle" menu on the right of Android Studio
- Navigated :app > Tasks > Android
- Double clicked on "signingReport" menu voice
Indeed the command "signingReport" was executed and in the console I got SHA1 code (both for debug and for release).
My problem is that right now I am not able to debug my app in the device anymore.
If I click on the "Debug" button of the top menu of Android Studio it calls "signingReport" command execute, instead of let me choose the device to debug app with.
I do not know howto comeback to the previous debug option.
UPDATED
I solved: what I've done is just going to the "Gradle" menu on the right and delete all "Run configuration" voices that Android Studio created after I run the command.
