I recently updated the Android Studio to 2.3. When I hit the instant run button, It compiles the app but doesn't open the app on the Android device. Even 'Hot Swap' is not enabled after that, it shows "No active 'app' launch". Any idea what I might be doing wrong. I tried creating a new project, but this error exists in that also.
I am getting below error:
Error while executing: am startservice
com.example/com.android.tools.fd.runtime.InstantRunService Starting
service: Intent { act=android.intent.action.MAIN
cat=[android.intent.category.LAUNCHER]
cmp=com.example/com.android.tools.fd.runtime.InstantRunService }
Error: Not found; no service started.
Got the same error after updating. As already noted, there's an open discussion on this topic. So far, the only work-around is that you actually disable instant run, that's the only thing that worked for me. You can do so in Preferences -> Build, Execution, Deployment -> Instant Run:
Turn it off and run the app again and it's going to work. That's the best we can do at this point.
This is a device related bug. There is a google issue discussion:

They have found some solutions:
Asus devices: you have to allow auto-start for apps you want to start with instant run https://www.asus.com/support/faq/1013752
Devices with MIUI: you have to disable MIUI optimization (see other answer in stackoverflow) https://stackoverflow.com/a/42579815/1341576
