How to get the app package name on Android

Get package via Android Studio

If we can get the Apk file, then drag the Apk directly into Android Studio, Android Studio will automatically parse the file, and after successful parsing it will open a new tab, and at the top of the tab you can see the package name

Get package via pm list packages

If we can get the Apk file, then drag the Apk directly into Android Studio, Android Studio will automatically parse the file, and after successful parsing it will open a new tab, and at the top of the tab you can see the package name

adb shell pm list packages | grep com.example.app

Get package via adb shell top

If we don’t know anything about the application, then we have to run the application. A running application takes up resources and can be located by looking at the output of top and further determining the package name from the ARGS column. If the output is truncated, you can enter the shell environment before executing the top command.

Get package adb shell dumpsys window

Actually the above two commands are still too slow for locating the application, the fastest way is to use dumpsys window directly. Again we run the application, but this time instead of looking at the resource usage of the application, we locate the application based on the current window focus, and the window related one is definitely looking for dumpsys window. The output may be different for different versions of the system, but the same is true, in one of the output lines there will be something like the following output

mFocusedApp=ActivityRecord{1970a93 u0 com.tencent.mm/.plugin.account.ui.WelcomeActivity t77}

Start with mFocusedApp, after u0 and before / is the package name, after / is the name of the Activity.
