adb-install:tldr:ec882

The command "adb install --fastdeploy ${filename-apk}" is used to install an Android application package (APK) onto an Android device via the Android Debug Bridge (ADB) command-line tool.

Here's a breakdown of the command:

• "adb": This refers to the ADB tool, which is a command-line utility provided by Android SDK. It allows communication between a computer and an Android device.
• "install": This is a command used with ADB to install an APK onto the connected Android device.
• "--fastdeploy": This is an optional flag that can be included with the ADB install command. It enables the use of the incremental deployment process, where only the parts of the APK that have changed since the last installation are pushed to the device. This can significantly reduce installation time for subsequent installations of the same APK, as it minimizes the data transfer required.
• "${filename-apk}": This is a placeholder for the actual APK filename. You need to replace "${filename-apk}" with the name of the APK file you want to install. Make sure the APK file is in the same directory location as the ADB tool or provide the full path to the APK file.

Overall, this command allows you to install an APK onto an Android device quickly using the ADB tool, leveraging incremental deployment to reduce installation time if the APK has already been installed before.
