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.

Android Developers. It is a client-server program that includes three components: A client , which sends commands. 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. 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. Force stop everything associated with package the app's package name. Kill all processes associated with package the app's package name. Issue a broadcast intent. Start monitoring with an Instrumentation instance. Start profiler on process , write results to file.
Dump the heap of process , write to file. Set app package to debug. Clear the package previous set for debugging with set-debug-app. Start monitoring for crashes or ANRs. Control screen compatibility mode of package. Override device display size.
Example: am display-size x Override device display density. Example: am display-density Print the given intent specification as a URI. Print the given intent specification as an intent: URI. Prints all packages, optionally only those whose package name contains the text in filter. Prints all known permissions, optionally only those in group.
List all test packages. Print the path to the APK of the given package. Installs a package specified by path to the system. Xbox Series X Bundle.

Where to Download Windows Legally. 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. Sort output of adb devices by connection type and device serial. Increase the socket listen backlog to allow for more simulataneous adb commands.
Improve error output for adb connect. Clean up help output. Add product. Avoid bricking new devices when using a too-old version of fastboot by allowing factory image packages to require support for specific partitions.
