【Android】-- adb shell 命令探索

標籤：android開發   android shell commen   

ADB是什麼，做android開發的沒有不知道的。

window下運行cmd，輸入adb help就會列印adb都能夠做的事情，包括 adb push 。。adb pull 。。 adb devices  adb install。。。 等等。。並且一搜一大把。 

其中有一個命令叫做  adb shell，android是基於linux的，shell模式下linux的命令可是非常多的，android去掉了許多linux的命令，那麼從這寫命令裡面又能夠發現什麼寶藏呢？尋寶之旅開啟！！

首先linux的shell模式有許多命令，例如 ls cd mkdir su ps vim等等許多控制命令，這些在android上都是支援的。但是它是android的核心啊，應該有些特殊點的吧。

通過命令cd /system/bin 進入bin目錄查看一下。

噢 my god 命令還是很多的嘛！

我們一般可以通過 命令 -h 來查看介紹，例如：

# am -ham -husage: am [subcommand] [options]usage: am start [-D] [-W] [-P <FILE>] [--start-profiler <FILE>]               [--R COUNT] [-S] <INTENT>       am startservice <INTENT>       am force-stop <PACKAGE>       am kill <PACKAGE>       am kill-all       am broadcast <INTENT>       am instrument [-r] [-e <NAME> <VALUE>] [-p <FILE>] [-w]               [--no-window-animation] <COMPONENT>       am profile [looper] start <PROCESS> <FILE>       am profile [looper] stop [<PROCESS>]       am dumpheap [flags] <PROCESS> <FILE>       am set-debug-app [-w] [--persistent] <PACKAGE>       am clear-debug-app       am monitor [--gdb <port>]       am screen-compat [on|off] <PACKAGE>       am display-size [reset|MxN]       am to-uri [INTENT]       am to-intent-uri [INTENT]am start: start an Activity.  Options are:    -D: enable debugging    -W: wait for launch to complete    --start-profiler <FILE>: start profiler and send results to <FILE>    -P <FILE>: like above, but profiling stops when app goes idle    -R: repeat the activity launch <COUNT> times.  Prior to each repeat,        the top activity will be finished.    -S: force stop the target app before starting the activityam startservice: start a Service.am force-stop: force stop everything associated with <PACKAGE>.am kill: Kill all processes associated with <PACKAGE>.  Only kills.  processes that are safe to kill -- that is, will not impact the user  experience.am kill-all: Kill all background processes.am broadcast: send a broadcast Intent.am instrument: start an Instrumentation.  Typically this target <COMPONENT>  is the form <TEST_PACKAGE>/<RUNNER_CLASS>.  Options are:    -r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT).  Use with        [-e perf true] to generate raw output for performance measurements.    -e <NAME> <VALUE>: set argument <NAME> to <VALUE>.  For test runners a        common form is [-e <testrunner_flag> <value>[,<value>...]].    -p <FILE>: write profiling data to <FILE>    -w: wait for instrumentation to finish before returning.  Required for        test runners.    --no-window-animation: turn off window animations will running.am profile: start and stop profiler on a process.am dumpheap: dump the heap of a process.  Options are:    -n: dump native heap instead of managed heapam set-debug-app: set application <PACKAGE> to debug.  Options are:    -w: wait for debugger when application starts    --persistent: retain this valueam clear-debug-app: clear the previously set-debug-app.am monitor: start monitoring for crashes or ANRs.    --gdb: start gdbserv on the given port at crash/ANRam screen-compat: control screen compatibility mode of <PACKAGE>.am display-size: override display size.am to-uri: print the given Intent specification as a URI.am to-intent-uri: print the given Intent specification as an intent: URI.<INTENT> specifications include these flags and arguments:    [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]    [-c <CATEGORY> [-c <CATEGORY>] ...]    [-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]    [--esn <EXTRA_KEY> ...]    [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]    [--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]    [--el <EXTRA_KEY> <EXTRA_LONG_VALUE> ...]    [--eu <EXTRA_KEY> <EXTRA_URI_VALUE> ...]    [--eia <EXTRA_KEY> <EXTRA_INT_VALUE>[,<EXTRA_INT_VALUE...]]    [--ela <EXTRA_KEY> <EXTRA_LONG_VALUE>[,<EXTRA_LONG_VALUE...]]    [-n <COMPONENT>] [-f <FLAGS>]    [--grant-read-uri-permission] [--grant-write-uri-permission]    [--debug-log-resolution] [--exclude-stopped-packages]    [--include-stopped-packages]    [--activity-brought-to-front] [--activity-clear-top]    [--activity-clear-when-task-reset] [--activity-exclude-from-recents]    [--activity-launched-from-history] [--activity-multiple-task]    [--activity-no-animation] [--activity-no-history]    [--activity-no-user-action] [--activity-previous-is-top]    [--activity-reorder-to-front] [--activity-reset-task-if-needed]    [--activity-single-top] [--activity-clear-task]    [--activity-task-on-home]    [--receiver-registered-only] [--receiver-replace-pending]    [--selector]    [<URI> | <PACKAGE> | <COMPONENT>]Error: Unknown command: -h

雖然-h沒法識別，可還是列印出了參數的。

1、am命令是非常有用的一個命令，使用此命令可以啟動 activity, services；發送 broadcast等等。

使用執行個體：如啟動一個 Activity：

格式：adb shell am start -n 包名/包名＋類名（-n 類名,-a action,-d date,-m MIME-TYPE,-c category,-e 擴充資料,等）。 

執行個體1：C:\Users\Administrator>adb shell am start -n com.android.camera/.CameraStarting: Intent { cmp=com.android.camera/.Camera } 

執行個體2：（帶extra 的 intent）C:\Users\Administrator>adb shell am start -n com.android.camera/.Camera -e abc helloStarting: Intent { cmp=com.android.camera/.Camera (has extras) }其中 extra 的 key 為 abc ,value 為字串 "hello" 

還可以發送命令類比手機低電環境：

執行個體：adb shell am broadcast -a android.intent.action.BATTERY_CHANGED --ei "level" 3 --ei "scale" 100

2、getprop/watchprops

getprop列出系統的屬性,前面十名字,後面是值
# getprop
getprop
[ro.secure]: [0]
[ro.allow.mock.location]: [1]
[ro.debuggable]: [1]
[persist.service.adb.enable]: [1]
[ro.kernel.qemu]: [1]
[ro.kernel.console]: [ttyS0]
[ro.kernel.android.checkjni]: [1]
[ro.kernel.android.qemud]: [ttyS1]
[ro.kernel.android.ndns]: [1]
[ro.factorytest]: [0]
[ro.serialno]: []

3、watchprosp動態監視這些屬性的變化,比如我修改系統的語言為中文,就會列印出:
# watchprops
watchprops
1269420653 persist.sys.language = ‘zh‘
1269420653 persist.sys.language = ‘CN‘

4、 wipe <system|data|all>
wipe表示清除模擬器或者真機上的資料,比如你的模擬器用了很久,裝了很多軟體就可以用這個來清除
system表示清除 /system下的資料
data表述清除 /data 下的資料
