Emulator disconnect frequently and Android Studio Stuck. How To fix it?

Question

I have a strange problem which cannot find any fix for it. Every thing is OK for the first time when i open emulator and AVD run normally. but after 5-10 minutes, the emulator disconnect,it lose it's internet connection and i cant connect to it,also the Android Studio completely stuck and nothing happen ! I should close the emulator and after that everything become normal again.

These are what I tested :

adb kill-server and then adb start-server

I also tried connecting and disconnecting again

adb connect localhost:5554 and also adb connect emualtor-5554 but still no result.

The worse part is that I can't use Android Studio anymore, even clicking on lines of codes don't work!

Every time I should close the emulator and open it again.

NOTE : I can't use Genymotion, and I don't want to use my device for debugging!

Can any body have any fix for this damn bug. it made me crazy ... thanks in advance

EDIT :

The problem is not something related to emulator. Today I try to debug with WiFi connection. Everything was good for a while till the problem happened again with my real device. In log it said :

deviceXXXXX disconnected

So the problem is with my ADB connection !

What I tested was adding port 5555 to firewall also added ADB to pass through firewall. But still the problem persists.

Answer 1

What's your android studio version, jdk version, os?

What api are you targeting?

Can be a problem with new feature of android studio 2 instant run.

First try would be turn in off.

Be aware if you are targeting N Developer Preview is required to use Java 8.

More radical way is to rollback to android studio 1.5 and test.
