问题
Started a new project, and this occurred to me:
I am using Genymotion as my emulator. Not sure what causes this problem.
I tried:
- Rebuilding the project
- Made sure I have enough space in my
emulator(I have 4.5gb left) - Check if it's already installed in the
emulator, it hasn't.
回答1:
Open terminal, and type adb shell to access the emulator shell.
Type settings put global verifier_verify_adb_installs 0 on the shell.
I think this is related to the recent Google Play Services update. The verifier is more strict. This command in essence disables the Verify Apps option. From this article.
回答2:
you have to try to remove the App installed in the emulator manually
回答3:
Hi @Matthew Francis For the solution you need deselect Verify apps from your genymotion or device setting,
Settings -> Security -> Deselect Verify Apps.
Now then after try it work,
回答4:
In my case, setting "verifier_verify_adb_installs" to 0 alone is not enough. I need to also set "package_verifier_enable" to 0:
e.g.
adb shell
settings put global package_verifier_enable 0

in Genymotion emulator please goto Seting > Secureity&Location > google play protect then off the "scan device for security threads" opetion
回答6:
In my case, stopping "Google Play Services for Instant Apps" solved the problem.
回答7:
In Genymotion emulators, just turning on the Developer options/USB debugging solved this problem in my case.
Genymotion: Installation failed with message INSTALL_FAILED_VERIFICATION_FAILURE. can be referred.

in my case, I disable google play protect, google play > play protect > setttings(gear icon) > turn off
