I. Connecting to an Android Device or Emulator:

A. USB Connection:

- Connect the device to the computer using a USB cable.

- Enable USB debugging mode on the device.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb devices" to check if it recognizes the connected device.

B. Wi-Fi Connection:

- Connect the device to the same Wi-Fi network as the computer.

- Enable USB debugging mode on the device.

- Connect the device to the computer using a USB cable.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb tcpip ", where is the desired port number.

- Disconnect the USB cable and execute the command "adb connect :", where is the IP address of the device and is the port number specified earlier.

II. Installing and Uninstalling Apps:

A. Installing an App using ADB:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb install ", where is the file path of the APK to be installed.

B. Uninstalling an App using ADB:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb uninstall ", where is the package name of the app to be uninstalled.

III. Transferring Files:

A. Pushing Files to the Device:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb push ", where is the file path on the computer and is the file path on the device.

B. Pulling Files from the Device:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb pull ", where is the file path on the device and is the file path on the computer.

IV. Capturing Screenshots:

A. Taking a Screenshot using ADB:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb shell screencap ", where is the file path where the screenshot will be saved on the device.

B. Recording a Screen using ADB:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb shell screenrecord ", where is the file path where the screen recording will be saved on the device.

V. Running Shell Commands:

A. Executing Shell Commands on the Device:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb shell ", where is the desired shell command to be executed on the device.

B. Interactive Shell Sessions:

- Ensure the device is connected via USB or Wi-Fi.

- Open a terminal or command prompt and navigate to the Android SDK platform-tools directory.

- Execute the command "adb shell" to start an interactive shell session with the device.

VI. Debugging Apps:

A. Logging and Debugging with ADB:

- Use the command "adb logcat" to display the device log.

- Filter the log messages using various options, such as tag, priority level, and more.

- Use the command "adb shell am start -D -n /" to start an activity with debug mode enabled.

B. Inspecting UI Layouts:

- Use the command "adb shell uiautomator dump" to capture the UI hierarchy of the current foreground application.

- Pull the XML file from the device using the command "adb pull /sdcard/window_dump.xml ".

- Analyze the XML file to understand the UI structure and elements.

By utilizing the various functionalities provided by ADB, developers can streamline their app development process and effectively debug their applications on Android devices or emulators. ADB is an essential tool for any Android developer and offers great flexibility and control over the development environment.
