Summary of common commands for Android ADB development

Adb is a very commonly used command for debugging during development. Let’s talk about the commonly used adb commands.

Simplify adb connection commands

If you specify an IP connection, it is usually adb connect 172.18.xxx.xxx. In this way, you will find that there are repeated commands to type each time you connect. Programmers want to reduce repetitive work, so now you can save the repeated commands. (The following is the configuration method under Mac):

• Create a new .alias_bash file
• Use the alias keyword to re-command in the file

 alias ac= "adb connect $1"    
 alias ad= "adb devices"    
 alias ak= "adb kill-server"    
 alias as = "adb start-server"  

• Modify the .bash_profile in the root directory, or other files starting with .bash, add source ./.alias_bash at the end and then re-execute source ./.bash_profile, or simply close the terminal and reopen it.
• Try using ac 172.18.**.**, you can connect to the machine directly, and you can see the device that adb is connected to by typing ad.

The above is just an example, you can add other simplified commands in the .alias_bash file.

adb multiple device specified connection

When using adb to connect to multiple devices, when you want to connect to the shell of a certain device, use adb -s 172.18.xx.xx:5555 shell.

If it is other commands, you can specify the device to execute. For example:

 adb -s 172.18.xx.xx:5555 install *.apk

adb file processing

Copy files from your computer to your device

Order:

 adb push <file path on the computer> <directory in the device>

example:

 adb push ~/sr.mp4 /sdcard/

Copy the files from the device to the computer

Order:

 adb pull <file path in device> [directory on computer]

The directory parameter on the computer can be omitted and the directory will be copied to the current directory by default.

example:

 adb pull /sdcard/sr.mp4 ~/tmp/

adb install uninstall application

adb install application

Command format:

 adb install [-lrtsdg]

parameter:

adb install can be followed by some optional parameters to control the behavior of installing APK. The available parameters and their meanings are as follows:

If you see output similar to the following after running the command (status is Success), the installation is successful:

 [100%] /data/ local /tmp/1.apk  
 pkg: /data/ local /tmp/1.apk  
 Success

adb uninstall application

Order:

 adb uninstall [-k]

Indicates the package name of the application. The -k parameter is optional and indicates uninstalling the application but retaining the data and cache directory.

Command example:

 adb uninstall com.aaron.test

adb start application

Start the activity

Command format:

 adb shell am start [options]

For example:

 adb shell am start -n com.aaron.test/.LauncherActivity

If you want to add parameters to the launched Intent, you can add them in key-value format.

 adb shell am start -n org.mazhuang.boottimemeasure/.MainActivity --es "url" "wxtlife.com"  

Start the servies

Command format:

 adb shell am startservice [options]

For example:

 adb shell am startservice -n com.aaron.test/.MusicService

Indicates calling up the music service.

Sending Broadcasts

Command format:

 adb shell am broadcast [options]

You can broadcast to all components or only to specified components.

For example, broadcast BOOT_COMPLETED to all components:

 adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

Send a broadcast to the specified receiver, example:

 adb shell am broadcast -a com.aaron. action .SHOW_TIME -n com.aaron.test/.PlaySerices

If the broadcast has parameters, add the parameter key and value at the end. For example:

 adb shell am broadcast -a com.aaron. action .SHOW_TIME -es "url"   "wxtlife.com"  

adb kill process

Order:

 adb shell am force -stop

Command example:

 adb shell am force -stop com.aaron.test

adb clear application cache, etc.

Order:

 adb shell pm clear

Indicates the application package name. The effect of this command is equivalent to clicking "Clear Cache" and "Clear Data" in the application information interface in the settings.

Command example:

 adb shell pm clear com.aaron.test

adb simulated events

Order:

 adb shell input keyevent

example:

 adb shell input keyevent 26 //Simulate the power button

adb view log

Command format:

 [adb] logcat [] ... [] ...

example:

 adb logcat *:W

Android logs are divided into the following priorities:

• V——Verbose (lowest, most output)
• D — Debug
• I——Info
• W — Warning
• E——Error
• F is for Fatal
• S —— Silent (highest, no output)

Filter the specified TAG

 adb logcat -s

Other common commands

View application list information

The basic command format for viewing the application list is

 adb shell pm list packages [-f] [-d] [-e] [-s] [-3] [-i] [-u] [ --user USER_ID] [FILTER]  

That is, based on adb shell pm list packages, you can add some parameters to filter and view different lists. The supported filtering parameters are as follows:

For example:

Third-party apps

 pm list packages -s

Applications whose package names contain a certain string

 adb shell pm list packages -3

View the command that contains the string aaron in the package name

 adb shell pm list packages aaron

View the front-end Activity

Order:

 adb shell dumpsys activity activities | grep mFocusedActivity

View running Services

Order:

 adb shell dumpsys activity services []

The parameter is not required. If specified, it means viewing the Services related to a certain package name. If not specified, it means viewing all Services.

CPU Information

Order:

 adb shell cat /proc/cpuinfo

Memory information

Memory information

Order:

 adb shell cat /proc/meminfo

Among them, MemTotal is the total memory of the device, and MemFree is the current free memory.

View CPU usage ranking

Order:

 adb shell busybox top
