Android Studio does not install latest application on device

Question

I'm following some tutorials about building apps in Android Studio, but for some reason it's not launching/installing the latest version of my app when I click 'run'. I have to manually uninstall the app on the phone and then click run after making changes in Android Studio for the app to get updated. Any ideas?

Here is the console output:

Waiting for device.

No apk changes detected. Skipping file upload, force stopping package instead.

Android Studio thinks that there are no changes and doesn't install the new APK. A workaround is to disable the "Skip installation if APK has not changed" option in Run > Edit Configurations.

Android Studio thinks that there are no changes and doesn't install the new APK. A workaround is to disable the "Skip installation if APK has not changed" option in Run > Edit Configurations >Android Application > app >Miscellaneous . Then uncheck "Skip installation if APK has not changed".

Another problem like this is instant Run you can manage it by :- Just go to "File -> Settings -> Build, Execution, Deployement -> Instant Run" and just disable it. With this Android Studio builds from scratch each time but it's better than not building it right.

Answer 3

This is actually a bug you can find more info Android Open Source Project - Issue Tracker

Disabling instant run option in edit configuration and adding -r flag to the install flags is best work around for now.!

Answer 4

option in Run > Edit Configurations >Android Application > app >Miscellaneous . Then uncheck "Skip installation if APK has not changed". THEN --> option in Build > clean project and rebuild project and reinstall APK in your device.

THIS WORKS FINE FOR ME, HOPE THIS HELP OTHER ALSO
