Improve incremental installation performance. Fix adb push --sync with multiple inputs. Improve performance of incremental apk installation. Improve error handling for incremental apk installation. Fix adb install-multi-package.

Fix some more crashes related to adb wireless pairing. Improve some error messages. Fix fastboot flashall on older devices such as Nexus 7. Fix crash when using adb -H. Fix hang in adb logcat when run before a device is connected.

Improve performance of adb install-multi on Android 10 or newer devices. Update support for wireless pairing. Add support for incremental APK installation. Improve performance of adb push on high-latency connections. Fix hang when using adb install on something that isn't actually a file. Add --fastdeploy option to adb install , for incremental updates to APKs while developing.

This also fixes a related bug in the Android Studio Profilers that causes an AdbCommandRejectedException , which you can see in the idea. Fix devices going offline on Windows. Improve adb install output and help text.

On Linux, when connecting to a newer adb server, instead of killing the server and starting an older one, adb attempts to launch the newer version transparently. Previously, adb root; adb wait-for-device could mistakenly return immediately if adb wait-for-device started before adb noticed that the device had disconnected. Fixes authentication—when the private key used for authentication does not match the public key—by calculating the public key from the private key, instead of assuming that they match.

Updated Windows requirements The platform tools now depend on the Windows Universal C Runtime, which is usually installed by default via Windows Update. If you see errors mentioning missing DLLs, you may need to manually fetch and install the runtime package.

Upon disconnection, adb will attempt to reconnect for up to 60 seconds before abandoning a connection. Fix Unicode console output on Windows. Thanks to external contributor Spencer Low!

Fix a file descriptor double-close that can occur, resulting in connections being closed when an adb connect happens simultaneously. Fix adb forward --list when used with more than one device connected. 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. Content and code samples on this page are subject to the licenses described in the Content License.

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. 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.

On some devices, the Developer options screen might be located or named differently. To connect to your device, follow these steps: Figure 1. Wireless ADB pairing dialog. Figure 2. Wireless adb IP and port number. Start an Activity specified by intent. Start the Service specified by intent.
