After android studio update api 24 emulator showing offline

I am using a MACbook. For one specific emulator its always showing offline. The emulator has a nexus 5 skin and is a api 24 build. When i try another emulator its fine and works. i tried re-creating the emulator. when i run adb devices it says the "unauthorized".

I tried the following: I went into the developer settings of the emulator and allowed usb debugging if to see if that would help but it did not. this happened after i updated android studio to 2.3. i also tried to wipe user data from emulator. What is going on here ?

UPDATE: THIS IS OCCURRing for my other emualtors above api 22 also . i had to switch to genymotion for now which seems to work fine and shows as online. it has something to do with updating android studio. after i re-installed studio and did not take the 2.3 update, the problem was resolved.

I had the same problem. I solved it by turning on USB debugging after unlocking developer options of the emulator by clicking 7x on the build number.

Don't know the exact issue but it appears there are some bugs/issues with the latest updates.

Personally I am seeing my tests fail when run by ./gradlew commands, but not when run via Android Studio IDE.

I experienced your offline issue as well, I found I could at least rectify this by running:

  • adb kill-server
  • adb devices

-- UPDATE --

After investigating this one a little more, I found there to be compatibility issues between Qt version 5.7.0 which the new emulator uses, and Ubuntu 14.04 and it's version of Qt. Whatever system you will be using, you will have some version of Qt installed.

I'm guessing this may be the cause/related to the issues you are experiencing.

I was successfully able to fix my system by downgrading the SDK tools from version 25.3.1 to 25.2.3. I don't get the speed improvements of the new emulator, but at least I can run my tests reliably.

Going to try resolve the issues between Qt versions, and will update this if I can get the new emulator to work correctly again.
