In Ubuntu do Android development, use ADB devices debug when the error appears in the face:

The problem happened before, and suddenly I forgot, mark. On the internet to find a bit, is basically some of the more troublesome way, but in my memory this problem should be able to solve the problem soon. And then I thought about the unusual hint.

$ adb Devices 5037 * * Daemon started successfully *List of devices attached????????????    No Permissions

The part of the red background should be a description of insufficient permissions, so I tried the following method:

1. Kill the current ADB service first

$ adb kill-server

2. Open the service with administrator privileges

1 sudo adb start-server 2 5037 *3 * Daemon started successfully *

3. View all Devices

1 [email protected]:/opt/adt/sdk/platform-tools$ adb devices23  nx403a    device

Everything is so simple!
