Android Install on Device Failure [INSTALL_CANCELED_BY_USER]

Question

I'm using Android Studio to connect to run app in my Xiaomi Redmi Note 3G device. My device is already found in the Choose Device Dialog, but I keep getting the [INSTALL_CANCELED_BY_USER] error :

I tried looking for solutions online, but there's no mention of Failure [INSTALL_CANCELED_BY_USER] error.

Answer 1

Happens to my Xiaomi phone after updated it to MIUI 8. Took me hours to figure it out!

Check the followings if you're a victim too:

1. Go to Settings -> Permissions -> Install via USB: Uncheck your App if it's listed.
2. Go to Settings -> Additional Settings -> Privacy: Check the Unknown Sources option.
3. Finally go to Settings -> Additional Settings -> Developer options: Check the Install via USB option.

Update (MIUI 8):

Signin in to MI account is required to enable Install via USB option.

Update 2

For some devices (e.g. Redmi) you might need to turn off MIUI Optimization and reboot your phone.

Settings > Additional Settings > Developer Options > MIUI Optimization

P.S. don't update MIUI unless necessary!
