Iam running this on my real phone only at first it went to capcha and said otp was successful, second time when i entered its showing failed verification please HELP 😢

Do you have android name directory in right corner in gradle??

[@chandandutta25]

2:56 I am not getting the options (do not build gradle task list during gradle sync) in my android studio hedgehog. Not able to get the signing report

same...did you find any solution?

[@ElSersh01]

@@mdtowhidulislam9871 i found another option in the same screen that has Gradle task or build words in it that i unchecked and it worked. looks like it changed name

[@hhhh-go6sr]

I think it was changed to "Configure all Gradle tasks during Gradle Sync (this can make Gradle Sync slower)" You have to check it instead.

[@KerrorJerty]

I found a solution. In new versions of Android Studio, you need to enable "Configure all Gradle tasks during Gradle Sync (this can make Gradle Sync slower)" in the Gradle experimental settings, and then go to "File" -> Sync Project with Gradle Files

[@oneafrica1708]

I am really thankfull up to the bottom of my heart...Though I did all the steps but am not recieving the otp in my phone

[@princeshortsvideo6689]

I already have task option but i don't have Android option in the task so how to get SHA1 ❓❓

[@suryak-bv2lj]

Gradle ->(at top television play symbol) execute gradle task -> gradle signingreport (even there is no recomandation just type full and run u get it) that's all enjoy...... If anyone used this info say thanks

[@ertugurlghazi7026]

i fixed this issue after researching for 2 hours, it is very simple , we will get this error otp verification failed if we use in emulator , solution is this that use the Real phone having sim card than it will work and code is simply fine

If you have done that then delete it from there and now try to get the otp, you will surely get it.
