The screencap command is a shell utility for taking a screenshot of a device display. The utility records screen activity to an MPEG-4 file. You can use this file to create promotional or training videos or for debugging and testing. Otherwise, the recording stops automatically at three minutes or the time limit set by --time-limit.
To begin recording your device screen, run the screenrecord command to record the video. Then, run the pull command to download the video from the device to the host computer. The utility records at the native display resolution and orientation by default, with a maximum length of three minutes.
Table 4. Starting in Android 7. Examine the collected profiles to understand which methods are executed frequently and which classes are used during app startup. Note: It is only possible to retrieve the execution profile filename if you have root access to the file system, for example, on an emulator.
If you test your app across multiple test devices, it may be useful to reset your device between tests, for example, to remove user data and reset the test environment.
You can perform a factory reset of a test device running Android 10 API level 29 or higher using the testharness adb shell command, as shown:. When restoring the device using testharness , the device automatically backs up the RSA key that allows debugging through the current workstation in a persistent location.
That is, after the device is reset, the workstation can continue to debug and issue adb commands to the device without manually registering a new key. Additionally, to help make it easier and more secure to keep testing your app, using the testharness to restore a device also changes the following device settings:.
If your app needs to detect and adapt to the default settings of the testharness command, use the ActivityManager. It includes commands such as. You can also execute SQLite commands from the command line, as shown:. Note: It is only possible to access a SQLite database if you have root access to the file system, for example, on an emulator. For more information, see the sqlite3 command line documentation.

A daemon adbd , which runs commands on a device. The daemon runs as a background process on each device. A server , which manages communication between the client and the daemon. The server runs as a background process on your development machine. How adb works When you start an adb client, the client first checks whether there is an adb server process already running.
For example: Emulator 1, console: Emulator 1, adb : Emulator 2, console: Emulator 2, adb : and so on. Enable adb debugging on your device To use adb with a device connected over USB, you must enable USB debugging in the device system settings, under Developer options.
