Использование команды Am

I. Обзор

Как разработчик, я считаю, что команда adb не будет незнакомой. Затем после подключения мобильного телефона к adb многие операции можно выполнять с помощью команды am:

(1) Позвоните по телефону 10086

(2) Откройте сайт www.gityuan.com

(3) ПускActivity: Стартовый пакет называется com.yuanhh.app , Основным видом деятельности является .MainActivity , И дополнительные данные заканчиваются на «website«Это ключ, а« yuanh.com »- это значение. Хотя выполнить эту функцию с помощью кода Java несложно, по крайней мере, требуется среда Android. С adb вам нужно только ввести следующие команды в окне adb:

Команда am также может запускать Service, Broadcast, kill process, monitor и др. Эти функции очень удобны для отладки программы.Далее я расскажу о все более и более подробных функциях am.

Два, команда Am

команда	особенности	Реализация
am start [options ] >	Начать деятельность	startActivityAsUser
am startservice >	Начать службу	startService
am stopservice >	Остановить службу	stopService
am broadcast >	Отправить трансляцию	broadcastIntent
am kill >	Убить указанный фоновый процесс	killBackgroundProcesses
am kill-all	Убить все фоновые процессы	killAllBackgroundProcesses
am force-stop >	Убить процесс	forceStopPackage
am hang	Система зависла	hang
am restart	перезагружать	restart
am bug-report	Создать отчет об ошибке	requestBugReport
am dumpheap > >	Вывести информацию о куче pid процесса в файл	dumpheap
am send-trim-memory > >	Затяните память процесса	setProcessMemoryTrimLevel
am monitor	монитор	MyActivityController.run

Фактическая реализация команды am находится в Am.java, и она почти всегда вызывается в конце ActivityManagerService Соответствующий метод для завершения, am monitor Кроме. Например, команды, представленные в предыдущем обзоре am start -a android.intent.action.VIEW -d http://gityuan.com , Starting Acitivty, наконец, вызывает метод startActivityAsUser () класса ActivityManagerService для завершения. Другой пример am kill-all Command, окончательная работа по реализации завершается методом killBackgroundProcesses () ActivityManagerService.

Далее поговорим о [options ]с > Смысл параметра и как правильно получить значение.

Три, варианты

3.1 Начало занятия

В основном для запуска команды Activity am start [options] Используйте параметр options, а затем укажите параметр [options] команды Activity:

-D: разрешить функцию отладки
-W: дождаться запуска приложения
-R >: Повторить действие COUNT раз
-S: перед запуском действия вызовите метод forceStopPackage (), чтобы принудительно остановить приложение.
—Opengl-trace: запустить, чтобы получить трассировку функции OpenGL
–user > | Текущий: укажите пользователя для запуска приложения, по умолчанию — текущий пользователь.
–start-profiler >: Запустить профилировщик и отправить результат в >;
-P >: Аналогично —start-profiler, разница в том, что когда приложение переходит в состояние ожидания, профилирование останавливается.
—Sampling INTERVAL: установить временной интервал выборки профилировщика, единицы мс;

Принцип реализации запуска Activity: если есть параметр -W, вызовите метод startActivityAndWait () для запуска, в противном случае startActivityAsUser ().

3.2 Затянуть память

Например: для процесса с pid = 12345 введите команду уплотнения памяти с level = RUNNING_LOW

Тогда диапазон значений уровня: HIDDEN, RUNNING_MODERATE, BACKGROUND, RUNNING_LOW, MODERATE, RUNNING_CRITICAL, COMPLETE.

3.3 Другое

Для подкоманды am можно установить дополнительные параметры startservice, stopservice, broadcast, kill, profile start, profile stop, dumpheap. —user . Большинство мобильных телефонов, представленных в настоящее время на рынке, работают в однопользовательском режиме, поэтому вы можете игнорировать этот параметр и использовать по умолчанию текущего пользователя.

Например: start услуга пользователя.

Четыре, намерение

Существует множество параметров и флагов Intent.Для удобства эта статья разделена на 3 типа параметров: часто используемые параметры, дополнительные параметры и параметры флагов.

4.1 Общие параметры

: Задайте имя пакета и реализуйте принцип Intent.setPackage ();

-f : Добавить флаги, принцип реализации Intent.setFlags (int), следующий параметр должен быть типа int;

am start -a android.intent.action.VIEW

am start -n com.yuanhh.app/.MainActivity

am start -d content://contacts/people/1

am start -t image/png

am start -c android.intent.category.APP_CONTACTS

4.2 Дополнительные параметры

(1). Основные типы

параметр	-e/-es	-esn	-ez	-ei	-el	-ef	-eu	-ecn
Типы	String	(String)null	boolean	int	long	float	uri	component

Например, параметр es является аббревиатурой Extra String. Примеры:

Вот -es website gityuan.com , Эквивалент Intent.putExtra («веб-сайт», «gityuan.com»);

параметр	-esa	-eia	-ela	-efa
Тип массива	String[]	int[]	long[]	float[]

Например, параметр eia является аббревиатурой от Extra int array, а несколько значений значений разделяются запятыми. Примеры:

Вот -ela weekday 1,2,3,4,5 , Эквивалентно Intent.putExtra («будний день», новый int [] <1,2,3,4,5>);

(3). Тип ArrayList

параметр	-esal	-eial	-elal	-efal
Тип списка	String	int	long	float

Например, параметр efal является аббревиатурой от Extra float Array List, а несколько значений значений разделяются запятыми. Примеры:

Вот -efal nums 1.2,2.2 , Эквивалентно созданию сначала переменной ArrayList, а затем помещению второго параметра через putExtra.

ADB Shell Commands

In this document

The Android Debug Bridge (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/.

Issuing Shell Commands

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:

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

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 ( 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:

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

See the Specification for arguments.

to-intent-uri

Print the given intent specification as an intent: URI.

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.

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:

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.

Table 4. screenrecord options

Options	Description
—help	Displays command syntax and options
—size	Sets the video size: 1280×720 . The default value is the device’s native display resolution (if supported), 1280×720 if not. For best results, use a size supported by your device’s Advanced Video Coding (AVC) encoder.
—bit-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:
—time-limit	Sets the maximum recording time, in seconds. The default and maximum value is 180 (3 minutes).
—rotate	Rotates the output 90 degrees. This feature is experimental.
—verbose	Displays 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:
