installation app blocked by play protect

问题:

When trying to install a signed application (app-release.apk), a "Blocked by Play Protect" alert is shown and the app is not installed. However, an unsigned application (app-debug.apk) can be installed without problems.

The error message:

Play Protect doesn't recognise this app's developer. Apps from unknown developers can sometimes be unsafe.

Why this error happened? What's the solution?

回答1:

I found the solution: Go to the link below and submit your application.

Play Protect Appeals Submission Form

After a few days, the problem will be fixed

回答2:

I've found the better solution. If you want to conquer this problem you should open your play store, in menu find Play Protect and and uncheck Scan device for security threats.

回答3:

Try to create a new key store and replace with old one, then rebuild a new signed APK.

Update: Note that if you're using a http connection with server ,you should use SSL.

Google play finds you as developer via your keystore.

and maybe your country IP is banned on Google when you generate your new keystore.

change your IP Address and generate new keystore, the problem will be fixed.

if you didn't succeed, use another Gmail in Android Studio and generate new keystore.

the solution lies in creating a new key when generating the signed apk. this worked for me without a fuss.

1. click on Build
2. click generate signed Bundle/APK...
3. choose either Bundle / APK (in my case APK) and click Next
4. click on create new (make sure you have a keystore path on the machine)
5. after everything, click finish to generate your signed apk

when you install, the warning will not come.
