Application
安装应用
adb install -r -t <apk文件路径> //-r：重新安装现有应用，并保留其数据；-t：允许安装测试 APK。
//等同于 adb shell pm install ... 具体规则查看 https://developer.android.com/studio/command-line/adb#pm
卸载应用
adb uninstall -k <pkg name> //-k：移除软件包后保留数据和缓存目录。
启动应用
adb shell am start <pkg name>
强制停止应用
adb shell am force-stop <pkg name>
Activity
启动activity
adb shell am start -n <pkg>/<Path from source root> //为什么要-n,https://developer.android.com/studio/command-line/adb#IntentSpec
想要带参数？
adb shell am start -n <pkg>/<Path from source root> --es title 标题 --ei type 1
具体规则同样是看intent参数的规范
查看顶层activity
adb shell dumpsys activity | grep "mResumedActivity"
adb shell dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'
Service
启动service
adb shell am startservice -n <pkg>/<Path from source root>
查看service是否存在
adb shell dumpsys activity services
adb shell dumpsys activity services | grep <service name>
Broadcast
查看系统发送了什么广播
adb shell dumpsys activity broadcasts
发送广播
adb shell am broadcast -a <action>
//带参数？再重申一遍https://developer.android.com/studio/command-line/adb#IntentSpec
ContentProvider
没有在android开发者文档中找到adb shell content的用法，只能从adb中查看用法
usage: adb shell content [subcommand] [options]
#增
usage: adb shell content insert --uri <URI> [--user <USER_ID>] --bind <BINDING> [--bind <BINDING>...]
<URI> a content provider URI.
<BINDING> binds a typed value to a column and is formatted:
<COLUMN_NAME>:<TYPE>:<COLUMN_VALUE> where:
<TYPE> specifies data type such as:
b - boolean, s - string, i - integer, l - long, f - float, d - double, n - null
Note: Omit the value for passing an empty string, e.g column:s:
Example:
# Add "new_setting" secure setting with value "new_value".
adb shell content insert --uri content://settings/secure --bind name:s:new_setting --bind value:s:new_value
#改
usage: adb shell content update --uri <URI> [--user <USER_ID>] [--where <WHERE>]
<WHERE> is a SQL style where clause in quotes (You have to escape single quotes - see example below).
Example:
# Change "new_setting" secure setting to "newer_value".
adb shell content update --uri content://settings/secure --bind value:s:newer_value --where "name='new_setting'"
#删
usage: adb shell content delete --uri <URI> [--user <USER_ID>] --bind <BINDING> [--bind <BINDING>...] [--where <WHERE>]
Example:
# Remove "new_setting" secure setting.
adb shell content delete --uri content://settings/secure --where "name='new_setting'"
#查
usage: adb shell content query --uri <URI> [--user <USER_ID>] [--projection <PROJECTION>] [--where <WHERE>] [--sort <SORT_ORDER>]
<PROJECTION> is a list of colon separated column names and is formatted:
<COLUMN_NAME>[:<COLUMN_NAME>...]
<SORT_ORDER> is the order in which rows in the result should be sorted.
Example:
# Select "name" and "value" columns from secure settings where "name" is equal to "new_setting" and sort the result by name in ascending order.
adb shell content query --uri content://settings/secure --projection name:value --where "name='new_setting'" --sort "name ASC"
查看所有的ContentProvider
adb shell dumpsys activity | grep ContentProviderRecord
//dumpsys信息中能看到该ContentProvider的connections等信息

例子中的表结构比较简单，只是代入学习简单用法。删、查和改的bean都是一样的。
主键（int） _id
值 （long）timestamp
adb shell content insert --uri content://com.panda.eyeprotect.provider/close_range_table --bind timestamp:s:1626958478458
删
adb shell content delete --uri content://com.panda.eyeprotect.provider/close_range_table --where _id=2
查
adb shell content query --uri content://com.panda.eyeprotect.provider/close_range_table --projection _id:timestamp --where _id=2
adb shell content query --uri content://com.panda.eyeprotect.provider/close_range_table --projection timestamp --where _id=2 //这样是只查timestamp列
改
adb shell content update --uri content://com.panda.eyeprotect.provider/close_range_table --bind timestamp:s:7777 --where _id=1
SettingsProvider
SettingsProvider继承于ContentProvider，所以就像上面的usage一样，都是以SettingsProvider中作为例子。从frameworks/base/packages/SettingsProvider/AndroidManifest.xml中可以看到
<provider android:name="SettingsProvider"
android:authorities="settings"
android:multiprocess="false"
android:exported="true"
android:singleUser="true"
android:initOrder="100"
android:visibleToInstantApps="true" />
authorities为settings，分别有system、secure和global三个表。
这里只简单列举查的使用
adb shell content query --uri content://settings/system
adb shell content query --uri content://settings/secure
adb shell content query --uri content://settings/global
这样就可以快速看到表内所有的数据。
SettingsProvider还封装了更为容易使用的命令
读数据
adb shell settings get <table name> <column name>
e.g.adb shell settings get system screen_brightness
写数据
adb shell settings get <table name> <column name> <value>
e.g.adb shell settings put system screen_brightness 230
