Android App not loading in Emulator after Android Studio 2.3 Update

Question

I have just uploaded my Android Studio version to 2.3, and I am now having problems testing my app in my emulator. It is a Nexus 5X emulator with Android 7.0 Nougat loaded on it (API 24), with an ABI: armeabi-v7a (I have an AMD processor, so to the best of my knowledge I can only use this). Before, it was a bit slow and would sometimes come up with a 'Not Responding' error, but clicking 'Wait' would always do the trick.

After the Android Studio update, when I press 'Run', it opens up & boots the emulator. However, once booted, it gets stuck on the "Launching App - Installing APKs" process. It probably shows that it is doing this for about 2 minutes, before stopping. It then shows "Launching Instant Run Service" for a few seconds. The green 'run' arrow then becomes active again, as if there is no emulator open. The emulator is open, but there is no app. If I click the green 'run' arrow with the emulator already open, it does a gradle build sync & then doesn't even attempt to launch the app/install APKs - it only says "Launching Instant Run Service" for a few seconds, even though nothing happens.

I have tried removing the emulator & recreating it, and I have also tried fiddling with some of the parameters as suggested in other posts which concern similar (but not identical) issues to this. The first time I tried to run the app on the emulator after the update, I had many messages pop up in the event log, saying Android Studio Can't Bind to Local 86xx for debugger, whilst the Android Device Monitor was opened. Ever since then, with the ADM closed, I have had the problem described above, with no error messages showing in the error log.

Any help with this issue would be very much appreciated - please note it concerns the very latest version of Android Studio which I have only just had a popup requesting that I install. Build Tools Version in build.gradle has also been updated from 24.0.2 to 25.0.0.

If you haven't already done it:

Open Tools -> Android -> SDK Manager
Select tab SDK Tools, flag Android Emulator (version 27.0.5 at the moment) and Apply

This solution worked for me, hope this can help
