Android emulator command line commands

For more information on disk images, use -help-disk-images .

If you do not specify -datadir , the emulator looks for the user-data image in the storage area of the AVD being used (see -avd )

Here are some examples:

• -shell-serial stdio is identical to -shell
• -shell-serial tcp::4444,server,nowait lets you communicate with the shell over TCP port 4444
• -shell-serial fdpair:3:6 lets a parent process communicate with the shell using fds 3 (in) and 6 (out)
• -shell-serial fdpair:0:1 uses the normal stdin and stdout fds, except that QEMU won’t tty-cook the data.

You can define the default verbose output options used by emulator instances in the Android environment variable ANDROID_VERBOSE. Define the options you want to use in a comma-delimited list, specifying only the stem of each option: -debug- .

Here’s an example showing ANDROID_VERBOSE defined with the -debug-init and -debug-modem options:

can be one of the following:
http:// :

The http:// prefix can be omitted. If the -http-proxy

command is not supplied, the emulator looks up the http_proxy environment variable and automatically uses any value matching the

format described above.

Note that the does not correlate to clock speed or other absolute metrics — it simply represents an abstract, relative delay factor applied non-deterministically in the emulator. Effective performance does not always scale in direct relationship with values.

Options are:

• -D : Enable debugging.
• -W : Wait for launch to complete.
• —start-profiler : Start profiler and send results to .
• -P : Like —start-profiler , but profiling stops when the app goes idle.
• -R : Repeat the activity launch times. Prior to each repeat, the top activity will be finished.
• -S : Force stop the target app before starting the activity.
• —opengl-trace : Enable tracing of OpenGL functions.
• —user | current : Specify which user to run as; if not specified, then run as the current user.

Options are:

• —user | current : Specify which user to run as; if not specified, then run as the current user.

(the app’s package name). This command kills only processes that are safe to kill and that will not impact the user experience.

Options are:

• —user | all | current : Specify user whose processes to kill; all users if not specified.

Options are:

• [—user | all | current] : Specify which user to send to; if not specified then send to all users.

Options are:

• -r : Print raw results (otherwise decode ). Use with [-e perf true] to generate raw output for performance measurements.
• -e : Set argument to . For test runners a common form is -e [, . ] .
• -p : Write profiling data to .
• -w : Wait for instrumentation to finish before returning. Required for test runners.
• —no-window-animation : Turn off window animations while running.
• —user | current : Specify which user instrumentation runs in; current user if not specified.

, write results to .

.

Options are:

• —user [ |current] : When supplying a process name, specify user of process to dump; uses current user if not specified.
• -n : Dump native heap instead of managed heap.

Options are:

• -w : Wait for debugger when application starts.
• —persistent : Retain this value.

Options are:

• —gdb : Start gdbserv on the given port at crash/ANR.

Example:
am display-size 1280×800

Example:
am display-density 480

See the Specification for arguments.

Specification for arguments

For activity manager commands that take a argument, you can specify the intent with the following options:

-a Specify the intent action, such as «android.intent.action.VIEW». You can declare this only once. -d Specify the intent data URI, such as «content://contacts/people/1». You can declare this only once. -t Specify the intent MIME type, such as «image/png». You can declare this only once. -c Specify an intent category, such as «android.intent.category.APP_CONTACTS». -n Specify the component name with package name prefix to create an explicit intent, such as «com.example.app/.ExampleActivity». -f Add flags to the intent, as supported by setFlags() . —esn Add a null extra. This option is not supported for URI intents. -e|—es Add string data as a key-value pair. —ez Add boolean data as a key-value pair. —ei Add integer data as a key-value pair. —el Add long data as a key-value pair. —ef Add float data as a key-value pair. —eu Add URI data as a key-value pair. —ecn Add a component name, which is converted and passed as a ComponentName object. —eia [, Add an array of integers. —ela [, Add an array of longs. —efa [, Add an array of floats. —grant-read-uri-permission Include the flag FLAG_GRANT_READ_URI_PERMISSION . —grant-write-uri-permission Include the flag FLAG_GRANT_WRITE_URI_PERMISSION . —debug-log-resolution Include the flag FLAG_DEBUG_LOG_RESOLUTION . —exclude-stopped-packages Include the flag FLAG_EXCLUDE_STOPPED_PACKAGES . —include-stopped-packages Include the flag FLAG_INCLUDE_STOPPED_PACKAGES . —activity-brought-to-front Include the flag FLAG_ACTIVITY_BROUGHT_TO_FRONT . —activity-clear-top Include the flag FLAG_ACTIVITY_CLEAR_TOP . —activity-clear-when-task-reset Include the flag FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET . —activity-exclude-from-recents Include the flag FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS . —activity-launched-from-history Include the flag FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY . —activity-multiple-task Include the flag FLAG_ACTIVITY_MULTIPLE_TASK . —activity-no-animation Include the flag FLAG_ACTIVITY_NO_ANIMATION . —activity-no-history Include the flag FLAG_ACTIVITY_NO_HISTORY . —activity-no-user-action Include the flag FLAG_ACTIVITY_NO_USER_ACTION . —activity-previous-is-top Include the flag FLAG_ACTIVITY_PREVIOUS_IS_TOP . —activity-reorder-to-front Include the flag FLAG_ACTIVITY_REORDER_TO_FRONT . —activity-reset-task-if-needed Include the flag FLAG_ACTIVITY_RESET_TASK_IF_NEEDED . —activity-single-top Include the flag FLAG_ACTIVITY_SINGLE_TOP . —activity-clear-task Include the flag FLAG_ACTIVITY_CLEAR_TASK . —activity-task-on-home Include the flag FLAG_ACTIVITY_TASK_ON_HOME . —receiver-registered-only Include the flag FLAG_RECEIVER_REGISTERED_ONLY . —receiver-replace-pending Include the flag FLAG_RECEIVER_REPLACE_PENDING . —selector Requires the use of -d and -t options to set the intent data and type.

You can directly specify a URI, package name, and component name when not qualified by one of the above options. When an argument is unqualified, the tool assumes the argument is a URI if it contains a «:» (colon); it assumes the argument is a component name if it contains a «/» (forward-slash); otherwise it assumes the argument is a package name.

Using package manager (pm)

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

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

Table 3. Available package manager commands.

Taking a device screenshot

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

To use the screencap from the command line, type the following:

Here’s an example screenshot session, using the adb shell to capture the screenshot and the pull command to download the file from the device:

Recording a device screen

The 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:

To use screenrecord from the command line, type the following:

Stop the screen recording by pressing Ctrl-C, 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. Here’s an example recording session:

The 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 screenrecord utility that you should be aware of when using it:

• Some devices may not be able to record at their native display resolution. If you encounter problems with screen recording, try using a lower screen resolution.
• Rotation of the screen during recording is not supported. If the screen does rotate during recording, some of the screen is cut off in the recording.
