Application Installation Failed in Android Studio

Question

Yesterday my app was running perfect from Android Studio but today when I started working on my app and running it i am getting error message continuously

Answer 1

In my case, it was very a silly and funny mistake. I, accidentally without actually knowing, checked "Android Debug Bridge, Use libUsb backend". Actually it should stay unchecked..

In Mac Pro, Go Preferences - > Build, Execution,Deployment -> Debugger.

Answer 2

**** For MAC OSX/Windows ****

Goto *

Android Studio - Preferences (In OSX)

Android Studio - File -> Settings (In Windows)

• in the menu bar then select

Build,Execution,Deployment - Instant run

• then uncheck it and rebuild it will works

Answer 3

In my own case, it was because my phone was out of space. For people that are facing this problem right now, if Clean Project + Build APKs does not work, check the available space on your phone or emulator.

I hope this helps.. Merry coding!

Answer 4

Just do the following step...

Build>Clean Project

after that Run project again, this worked for me

Answer 5

Before trying anything else in this post, I would do Build >> Clean Project. It solved my problem and it is the simplest solution. Sometimes, the cleaning doesnt get some links, so I also recommend you to restart your devices, either virtual or physical.

If it doesnt work out, try turning of Instant Run by File > Settings > Build,Execution,Deployment > Instant Run > Un-check

Only after trying this two simple solutions, I would try the others.

Answer 6

Allow or enable "Installation from USB" in the developer options.
