ADB stands for Android Debug Bridge.  It is a tool you can use that allows you to connect an Android device over a USB cable to your computer.  With this connection you can uninstall apps, issue shell commands to your device, install apps, and do more with your device.  For more information on this look at this and view this resource.

Appdome is a mobile integration platform you can use to enable extended logs in Android apps.

Using Appdome, there are no development or coding prerequisites.  For example, there is no Appdome SDK, libraries, or plug-ins to implement.

  2. Navigate to Settings > Advanced > Developer options.
    • Check ‘USB debugging’ and click OK on the prompt.
  3. When the device is connected to the computer, you should be prompted to “Allow USB debugging.”  If so, check the box to “Always allow from this computer.
