Answer 1

I found the solution go to

settings>build,execute,deployment>instant run>Enable instant run to hot swap code /resource change on deploy(unchecked this option)

This will work on 3.4 android studio too. thanks

Answer 2

I had the same issue in MIUI. Enabling OEM unlocking worked for me without disabling MIUI optimization.

Below is a screenshot of my Redmi 3s prime developer options setting:

Answer 3

Change your applicationId in the android/app/build.gradle file.

For example:

// Change this
applicationId "com.example.myAndroidApp"
//
// to this
applicationId "com.example.somethingElse"

Then Sync your gradle then you can able to install your app, if the previous applicationId is your production id the again change it the previous one now the device will allow to install the app.

Hope this may help you....
