Hi @OriginLive and thanks for questionning. It looks like an adb problem, so I'd suggest you to try to restart adb server:

adb kill-server
adb start-server

Please let us know if it works.

[OriginLive]

adb start-server

• daemon not running; starting now at tcp:5037
• daemon started successfully

however no change. What's wrong with my adb?

Hi @OriginLive . This issue looks similar to #1026 and #1027. Could you please check your Android SDK Platform Tools version? If it equals 29 then I recommend you to downgrade tools version to 28, because there was some bugs introduced in this version. To do that please do the following:

• Open Android Studio
• Click Configure
• Choose SDK Manager
• Open SDK Tools
• Uncheck Android SDK Platform Tools and click Apply
• Download Android SDK Platform Tools 28 using this link : https://dl.google.com/android/repository/platform-tools_r28.0.0-windows.zip
• Unzip this folder into Android SDK Location folder that is indicated at SDK Manager

Please let us know if this works for you.

It looks like this behaviour is found on Android Q Beta emulators. Google team already informed about that: https://issuetracker.google.com/issues/133771463

Hello, changing the platform tools didn't help, however as mentioned, i've switched the emulator api to version 28 and everything works as intended. Thanks!
I guess we'll have to wait for 29 to be stable.

@OriginLive Glad to hear that your issue is resolved.

Hello, I had similar issue on emulator, using Android SDK Platform Tools Version 29.
I was able to work around this following these steps:

Follow below steps:-

1. adb kill-server
2. adb root
