Android Studio-错误安装APK

Question

I am a new user to Android Studio. I took a class over the summer and all my projects worked (and still work). I have followed all the advice from all the advice columns but I am still getting "Session 'app': Error Installing APK" when I try running my latest projects on my Samsung S4 mini. Again, all the other projects from this summer still work. I have tried

• restarting everything (android studio, computer, phone, etc)
• I have reloaded Android Studio
• I have created multiple signatures and followed the directions on https://developer.android.com/studio/publish/app-signing.html

Does anyone have any other suggestions??

Answer 1

(can't comment yet, so the answer)

Have you seen these -

Session 'app': Error Installing APK

Session 'app' error while installing APK

Error on installing apk - parsing the package

Android error: Failed to install *.apk on device *: timeout

Answer 2

To resolve this error uncheck the instant run in File >Settings >Build,Execution,Deployment > Instant Run

This works 100%.

Answer 3

Enable "Install Via USB" feature form developer setting of your android phone.

1. Go to Additional setting -> Developer setting (Provided you have enabled it by clicking on version for multiple tymes )
2. Enable "Install Via USB"

Good luck
