Is there a generic adb command?
Short answer: No
Currently, the ADB shell only supports its own list of available commands; you simply cannot filter them into an application type, such as a browser.
adb shell pm list packages []
adb shell pm list packages
adb shell pm list packages -f See their associated file.
adb shell pm list packages -d Filter to only show disabled packages.
adb shell pm list packages -e Filter to only show enabled packages.
adb shell pm list packages -s Filter to only show system packages.
adb shell pm list packages -3 Filter to only show third party packages.
adb shell pm list packages -i See the installer for the packages.
adb shell pm list packages -u Also include uninstalled packages.
