The Android system provides a set of on-device developer options that will help you test your application. These options are available in the Settings menu of any Android device. On Android 4.2 and higher, the developer options are hidden. Click on the About phone option in the Settings menu and click on the Build number seven times to make them available. The following screenshot shows the Developer options in Android's Settings menu:
The Developer options are organized into seven categories, described as follows:
General: This option is not present in any category. For example, you can get a bug report by selecting the Take bug report option.
Debugging: This category includes useful tools to debug your application. For example, when you want to test your application on a real device, you should check the USB debugging option contained in this category. You can also select a debug app (Select debug app) or allow mock locations (Allow mock locations).
