Using Android under the ADB shell

ADB is a very useful tool, it can be used to debug the program on the Andorid, we can use it as a PC to access the interface of the Andorid system, through which can be used in the Android system files of various management, if there is root authority, basic all the operation can be completed. Let's start with a simple example to illustrate the use of the ADB shell (this is the host file that modifies the Android system):

Add the \{NDK root}\android-sdk\platform-tools directory to the environment variable before execution, or switch to the directory where Adb.exe is located before executing the command, CD \{ndk root}\android-sdk\ Platform-tools.

ADB Root gets root privileges

ADB remount set/system to read/write

adb pull/system/etc/hosts to download the Hosts file to the PC, the default directory is android-sdk\platform-tools\, after downloading, directly on the PC to complete the modification

ADB push hosts/system/etc/hosts upload the modified files on your PC to your phone
