The Android Debug Bridge (ADB) is a command-line tool that can be used to install, uninstall, and debug applications. It also may be used to transfer files and access a device shell. It also is a necessary component for tools such as scrcpy or Vysor.
The stock Keitais do not come with Google Play Services, or the Play Store. Also, the phones do not come with any built in way to install apps.
Keitais bought from online sellers will sometimes preload the phones with Aurora Store or F-Droid. Otherwise, you will need to use ADB in order to install apps.
Setup
First you will need to enable USB Debugging on the phone. Go into Settings>About Phone, in here click Build Number 5 times (It will say “You are now a Developer!”). You will now have access to Developer options which will be in Settings>More Settings>Dev Options. In here find USB Debugging and enable it. Now you may make use of ADB.
Installation
Windows
First, download the Google USB Driver and install it.
Afterwards, download SDK Platform Tools. After unzipping the download you may run commands using ADB from the folder.
In order to do do, navigate to the folder and change the text in the address bar to “cmd”, after pressing Enter you will get a terminal in the folder. You can now run ADB and Fastboot commands from the terminal.
Linux
Download SDK Platform Tools. After unzipping the download you may run commands using ADB from the folder.
Many desktop environments support right clicking in the folder and opening it in the terminal. However, if this is not the case for you simply navigate to the folder in the terminal.
You may need to right click ADB and Fastboot and make them executable.
You can now run ADB and Fastboot commands from the terminal. You will need to prefix every command with ./. (e.g. ./adb devices).
Mac
Download SDK Platform Tools. After unzipping the download you may run commands using ADB from the folder.
Open Terminal and type cd followed by a space. Then, drag the platform-tools folder from your Finder window directly into the Terminal window and press Enter.
You will need to prefix every command with ./. (e.g. ./adb devices).
You may need to make ADB and Fastboot executable via terminal. (Please let us know if that is or is not the case!).
