Launch App via adb without knowing Activity name [duplicate]

Answer 1

Using latest versions (at least API 25) you can start the default Activity, without knowing its name, and not using monkey:

PKG=com.android.calculator2
adb shell am start $PKG/$(adb shell cmd package resolve-activity -c android.intent.category.LAUNCHER $PKG | sed -n '/name=/s/^.*name=//p')

Answer 2

If you have the apk file, you can install and start the app using droidbot.

> droidbot -d emulator-5554 -a <xxx.apk> -install_app -policy none -count 0

DroidBot is based on adb, but it uses static analysis to extract the Activity name automatically.

Answer 3

Yes, it is possible to launch an app via adb shell making use of the monkey tool.

Using the command from this answer:

adb shell monkey -p app.package.name -c android.intent.category.LAUNCHER 1

This command simulates the app icon click, so the intent implicit intent LAUNCHER is delivered to the specific receiver declared in app manifest (MAIN)
