    Issuing Shell Commands

    - -

    Adb provides a Unix shell that you can use to run a variety of commands on an emulator -or connected device. The command binaries are stored in the file system of the emulator or device, -at /system/bin/... - -

    Two of the most common command tools are activity manager ({@code am}) and -package manager ({@code pm}).

    - -

    You can use the shell command to issue commands, with or without entering -the adb remote shell on the emulator/device. To issue a single command without entering a -remote shell, use the shell command like this:

    - - 
    adb [-d|-e|-s <serialNumber>] shell <shell_command>
    - -

    Or enter a remote shell on an emulator/device like this:

    - - 
    adb [-d|-e|-s <serialNumber>] shell
    - -

    When you are ready to exit the remote shell, press CTRL+D or type -exit.

    - - - - - -

    Using activity manager (am)

    - -

    Within an adb shell, you can issue commands with the activity manager ({@code am}) tool to -perform various system actions, such as start an activity, force-stop a process, -broadcast an intent, modify the device screen properties, and more. While in a shell, -the syntax is:

    -
    -am <command>
-
    - -

    You can also issue an activity manager command directly from adb -without entering a remote shell. For example:

    -
    -adb shell am start -a android.intent.action.VIEW

    Examining sqlite3 databases from a remote shell

    - -

    From an adb remote shell, you can use the -sqlite3 command-line program to -manage SQLite databases created by Android applications. The -sqlite3 tool includes many useful commands, such as -.dump to print out the contents of a table and -.schema to print the SQL CREATE statement for an existing table. -The tool also gives you the ability to execute SQLite commands on the fly.

    - -

    To use sqlite3, enter a remote shell on the emulator instance, as described above, -then invoke the tool using the sqlite3 command. Optionally, when invoking -sqlite3 you can specify the full path to the database you want to explore. -Emulator/device instances store SQLite3 databases in the folder -/data/data/<package_name>/databases/.

    - -

    Here's an example:

    - -
    adb -s emulator-5554 shell
-# sqlite3 /data/data/com.example.google.rss.rssexample/databases/rssitems.db
-SQLite version 3.3.12
-Enter ".help" for instructions
-.... enter commands, then quit...
-sqlite> .exit
    - -

    Once you've invoked sqlite3, you can issue sqlite3 commands in the -shell. To exit and return to the adb remote shell, use exit or CTRL+D. - - - - -

    Recording a device screen

    - -

    The {@code screenrecord} command is a shell utility for recording the display of devices - running Android 4.4 (API level 19) and higher. The utility records screen activity to an MPEG-4 - file, which you can then download and use as part of a video presentation. This utility is useful - for developers who want to create promotional or training videos without using a separate - recording device.

    - -

    To use the {@code screenrecord} from the command line, type the following: - -

    -$ adb shell screenrecord /sdcard/demo.mp4
-
    - -

    Stop the screen recording by pressing Ctrl-C, otherwise the recording stops automatically -at three minutes or the time limit set by {@code --time-limit}.

    - -

    Here's an example recording session, using the adb shell to record the video and the -{@code pull} command to download the file from the device:

    - -

    -$ adb shell
-shell@ $ screenrecord --verbose /sdcard/demo.mp4
-(press Ctrl-C to stop)
-shell@ $ exit
-$ adb pull /sdcard/demo.mp4
-
    - -

    The {@code screenrecord} utility can record at any supported resolution and bit rate you - request, while retaining the aspect ratio of the device display. The utility records at the native - display resolution and orientation by default, with a maximum length of three minutes.

    - -

    There are some known limitations of the {@code screenrecord} utility that you should be aware - of when using it:

    - - - - -

    Table 4. {@code screenrecord} options

    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    OptionsDescription
    --help - Displays a usage summary.
    - --size <WIDTHxHEIGHT> - Sets the video size, for example: {@code 1280x720}. The default value is the device's main - display resolution (if supported), 1280x720 if not. For best results, use a size supported - by your device's Advanced Video Coding (AVC) encoder.
    --bit-rate <RATE>Sets the video bit rate for the video, in megabits per second. The default value is 4Mbps. - You can increase the bit rate to improve video quality or lower it for smaller movie - files. The following example sets the recording bit rate to 6Mbps: - 
    screenrecord --bit-rate 6000000 /sdcard/demo.mp4
    -
    --time-limit <TIME>Sets the maximum recording time, in seconds. The default and maximum value is 180 - (3 minutes).
    --rotateRotates the output 90 degrees. This feature is experimental.
    --verboseDisplays log information on command line screen. If you do not set this option, - the utility does not display any information while running.

    UI/Application Exerciser Monkey

    - -

    The Monkey is a program that runs on your emulator or device and generates pseudo-random -streams of user events such as clicks, touches, or gestures, as well as a number of system-level -events. You can use the Monkey to stress-test applications that you are developing, -in a random yet repeatable manner.

    - -

    The simplest way to use the monkey is with the following command, which launches your -application and sends 500 pseudo-random events to it.

    - -
    adb shell monkey -v -p your.package.name 500
    - -

    For more information about command options for Monkey, see the complete -UI/Application Exerciser Monkey documentation page.

    - - - - - -

    Other shell commands

    - -

    For a list of all the available shell programs, use the following command:

    - -
    adb shell ls /system/bin
    - -

    Help is available for most of the commands.

    - -

    Enabling logcat logging

    - -

    The Android logging system provides a mechanism for collecting and viewing system debug output. Logs from various applications and portions of the system are collected in a series of circular buffers, which then can be viewed and filtered by the logcat command.

    - -

    You can use the logcat command to view and follow the contents of the system's log buffers. The general usage is:

    - -
    [adb] logcat [option] ... [filter-spec] ...
    - -

    You can use the logcat command from your development computer or from a remote adb shell in an emulator/device instance. To view log output in your development computer, you use

    - -
    adb logcat
    - -

    and from a remote adb shell you use

    - -
    logcat
    - -

    See Reading and Writing Logs for complete information about logcat commend options and filter specifications.

    Using package manager (pm)

    + +

    Within an adb shell, you can issue commands with the package manager ({@code pm}) tool to +perform actions and queries on application packages installed on the device. While in a shell, +the syntax is:

    +
    +pm <command>
+
    + +

    You can also issue a package manager command directly from adb +without entering a remote shell. For example:

    +
    +adb shell pm uninstall com.example.MyApp
+
    + +

    Taking a device screenshot

    + +

    The {@code screencap} command is a shell utility for taking a screenshot of a device display. +While in a shell, the syntax is: +

    + +
    +screencap <filename>
+
    + + +

    To use the {@code screencap} from the command line, type the following: + +

    +$ adb shell screencap /sdcard/screen.png
+
    + +

    Here's an example screenshot session, using the adb shell to capture the screenshot and the +{@code pull} command to download the file from the device:

    + +

    +$ adb shell
+shell@ $ screencap /sdcard/screen.png
+shell@ $ exit
+$ adb pull /sdcard/screen.png
+
    + + +

    Recording a device screen

    + +

    The {@code screenrecord} command is a shell utility for recording the display of devices + running Android 4.4 (API level 19) and higher. The utility records screen activity to an MPEG-4 + file.

    + +

    Note: Audio is not recorded with the video file.

    + +

    A developer can use this file to create promotional or training videos. While in a shell, the syntax is:

    + +
    +screenrecord [options] <filename>
+
    + +

    To use {@code screenrecord} from the command line, type the following: + +

    +$ adb shell screenrecord /sdcard/demo.mp4
+
    + +

    Stop the screen recording by pressing Ctrl-C, otherwise the recording stops automatically +at three minutes or the time limit set by {@code --time-limit}.

    + +

    To begin recording your device screen, run the {@code screenrecord} command to record +the video. Then, run the {@code pull} command to download the video from the device to the host +computer. Here's an example recording session:

    + +

    +$ adb shell
+shell@ $ screenrecord --verbose /sdcard/demo.mp4
+(press Ctrl-C to stop)
+shell@ $ exit
+$ adb pull /sdcard/demo.mp4
+
    + +

    The {@code screenrecord} utility can record at any supported resolution and bit rate you + request, while retaining the aspect ratio of the device display. The utility records at the native + display resolution and orientation by default, with a maximum length of three minutes.

    + +

    There are some known limitations of the {@code screenrecord} utility that you should be aware + of when using it:

    + + + + +

    Table 4. {@code screenrecord} options

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    OptionsDescription
    --help + Displays command syntax and options
    + --size <WIDTHxHEIGHT> + Sets the video size: {@code 1280x720}. The default value is the device's native + display resolution (if supported), 1280x720 if not. For best results, use a size supported + by your device's Advanced Video Coding (AVC) encoder.
    --bit-rate <RATE>Sets the video bit rate for the video, in megabits per second. The default value is 4Mbps. + You can increase the bit rate to improve video quality, but doing so results in larger movie + files. The following example sets the recording bit rate to 6Mbps: + 
    screenrecord --bit-rate 6000000 /sdcard/demo.mp4
    +
    --time-limit <TIME>Sets the maximum recording time, in seconds. The default and maximum value is 180 + (3 minutes).
    --rotateRotates the output 90 degrees. This feature is experimental.
    --verboseDisplays log information on the command-line screen. If you do not set this option, + the utility does not display any information while running.
    + + +

    Other shell commands

    + +

    For a list of all the available shell programs, use the following command:

    + +
    adb shell ls /system/bin
    + +

    Help is available for most of the commands.
