for a long time i was installing .apk on my device with no problem!The last days for every app that i try to install the next problem appears! In the console i see the message Installing myapp.apk for 3 minutes and after that i get the following messages:
Failed to install myapp.apk on device 'My device'
(null)
Launch canceled!
Any solution or possible error?
This seems to occure sometimes when using adb.
There should be a timeout for the adb to react. If you’re doing it with an AVD image, just restart that. If you’re doing it with a device, just try to restart it (restart, not just turn it off and on again – that will not properly close all apps due to fast boot in newer Android versions). Works fine for me each time I get this problem.
