ADB command Highlights

What is ADB?

The ADB tool is Android Debug Bridge (Android) tools. It is a command-line window for the computer to interact with the emulator or the real device.
Common operations:

• Send files to an Android device, or drag files from Android to a local
• Install/uninstall apps on your Android device
• Export the app's logs to a local
• Screen Cutting
  Thinking: What is the difference between the points above that can be substituted in other ways?

How is adb used?

1. Download the ADB compressed package, unzip, add environment variables, and then can be used in a DOS environment.
2. USB connects PC and phone, including Android device in normal boot state, USB cable and various interfaces intact.
3. Android Device developer options and USB debug mode are turned on
4. The device driver status is normal. This seems to be in Linux and Mac OS X do not worry, under Windows may encounter the need to install the driver, confirm this can right-click "Computer"-"Properties", to " Device Manager to see if there is a yellow exclamation point or question mark on the relevant device, if not, the driver status is OK. Otherwise you can download a mobile helper class program to install the driver first.
5. Verify the status after connecting the computer and the device via the USB cable.

Problems:

ADB devices no device: You can check your phone driver with the Driver Wizard and restart your computer after the driver is installed.
ADB devices Unauthorized: Workaround: Remove the USB debug authorization from the developer mode, assistant feature, phone settings, and reopen developer mode

Loading package

如果在电脑D盘下面有个a.apk文件，只需要一行命令就安装到手机上：adb install d:/a.apk如果已经安装了这个程序，可以通过以下命令覆盖安装：adb install -r d:/a.apk保留数据和缓存文件，重新安装 apkadb install -r a.apk安装包在android设备中adb shell pm install apk在移动端的路径

Uninstalling packages

adb uninstall 包名卸载软件但是保留配置和缓存文件:adb uninstall -k 包名

If you have more than one emulator or real machine on your machine, you need to specify a specific emulator or a real machine using the-s command line parameter. For example, the following command installs, re-installs, and uninstalls applications on the emulator and the real machine, respectively.

Package management, how to know an app package name?

The package name in the Android system is a unique identifier for an app, and different apps can have the same name, but the package name cannot be the same.

For example I can build an app myself called "", but my app's package name cannot be com.tencent.mm (the package name for this), if I specify the package name if also consistent, then my phone only allow to install one of these two apps. Speaking of which many people will have doubts, if someone maliciously made a and the content of the same app, the name and package names and the same, how to tell? Android in order to prevent this, but also made a signature thing, the signature of the general we do not have, so you can sign to identify who the app is.

1、看源代码当有源代码的时候，可以到工程目录下的 “AndroidManifest.xml”文件下查看package这一项。2、adb命令查看列出手机装的所有 app 的包名：adb shell pm list packages 列出系统应用的所有包名：adb shell pm list packages -s 列出除了系统应用的第三方应用包名：adb shell pm list packages -3推测一个包中可能带有的关键字：adb shell dumpsys activity | findstr mFocusedActivity清除应用数据与缓存adb shell pm clear 应用包名

1、接收电脑文件语法：adb push local remote案例：adb push d:/a.txt /sdcard/  把电脑 D 盘下的 a.txt 文件推送到手机 sdcard 目录下2、上传文件到电脑语法:adb pull remote local案例：adb pull /sdcard/a.txt d:/   上传位于/sdcard/目录下的 a.txt 文件到电脑的 D 盘根目录下

Screenshot, Screen recorder

可以在安卓设备上装个QQ之类的软件，进行截屏adb shell screencap /sdcard/a.pngadb shell /system/bin/screencap -p /sdcard/a.png2、使用adb进行屏幕录像adb shell screenrecord /sdcard/a.mp4通过ctrl+c停止录制，你可以在sdcard目录下查看。妈妈再也不担心我到处找录制视频的软件了。
