The refined strategy also reflects lessons learned during the initial phase of implementation, aiming to more efficiently and comprehensively achieve The mechanism was established to provide better access for people adversely affected by ADBassisted projects to voice and seek solutions to their It aims to help them understand political economy factors that shape actual outcomes, and to simplify the complexities of policy reform.

Example: am display-density to-uri intent Print the given intent specification as a URI. Specification for intent arguments For activity manager commands that take an intent argument, you can specify the intent with the following options:.

Within an adb shell, you can issue commands with the package manager pm tool to perform actions and queries on app packages installed on the device. You can also issue a package manager command directly from adb without entering a remote shell. Options: -f : See their associated file.

Options: -g : Organize by group. Options: -f : List the APK file for the test package. Options: -r : Reinstall an existing app, keeping its data. This feature is only supported on certain devices. This option forces adb to use the feature or fail if it is not supported with verbose information on why it failed.

Options: -k : Keep the data and cache directories around after package removal. On devices running Android 6. On devices running Android 5. Location values: 0 : Auto: Let system decide the best location. Note: This is only intended for debugging; using this can cause apps to break and other undesireable behavior.

To help you develop and test your device management or other enterprise apps, you can issue commands to the device policy manager dpm tool. Use the tool to control the active admin app or change a policy's status data on the device. You can also issue a device policy manager command directly from adb without entering a remote shell:. You can also pass --user current to select the current user. The app must declare android:testOnly in the manifest. This command also removes device and profile owners.

This is useful to avoid the device's scheduling restrictions when developing apps that manage freeze-periods. See Manage system updates. Supported on devices running Android 9. This command is rate-limited.

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. 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 5. Starting in Android 7. You might want to examine the collected profiles to understand which methods are determined to be frequently executed and which classes are used during app startup.

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 below.

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 you app needs to detect and adapt to the default settings of the testharness command, you can use the ActivityManager. It includes commands such as. You can also execute SQLite commands from the command line, as shown below. For more information, see the sqlite3 command line documentation.

The client runs on your development machine. You can invoke a client from a command-line terminal by issuing an adb command. 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.

Now disconnect USB cable and run adb devices , your device should be listed as connected. Note: Use the parameter -s seed to execute the same commands over and over again in order to reproduce any crashes that happen during the monkey run.
