adb-shell:tldr:8c3fd

The command "adb shell am start -n ${package}/${activity}" is used to start a specific Android application component from the command line on an Android device.

• "adb" stands for Android Debug Bridge, a command-line tool used to communicate with an Android device connected to a computer.
• "shell" refers to running a command or script in the remote shell of the device.
• "am" stands for Activity Manager, which manages all the application components and lifecycle events in an Android device.
• "start" is the action to start an activity or service.
• "-n" is a flag that specifies the next arguments as the component name.
• "${package}" denotes the package name of the application. Replace it with the actual package name.
• "${activity}" represents the activity name of the application. Replace it with the actual activity name.

By replacing ${package} and ${activity} with the real package name and activity name of an application, you can launch that specific component directly from the command line using adb.
