Android. Start fragment from adb

Question

I want to run a fragment via adb shell. Do so

adb shell am start -n com.example.myapplication/com.example.myapplication.MainActivity -e":android:show_fragment" com.example.myapplication.BlankFragment2

result

Starting: Intent { cmp=com.example.myapplication/.MainActivity (has extras) }

but only the activity opens without the fragment. What i do wrong?

Answer 1

You can't open Fragment without coding just using adb. ADB works with system. Activity is a part of system, but not Fragment.

To open Fragment from ADB in your Activity in onCreate method you need to check Extra:

    val showFragment = intent.getStringExtra("show_fragment")
    if (showFragment != null) {
        if (showFragment == "StreamListFragment") {
            supportFragmentManager.beginTransaction()
                .replace(R.id.container, StreamListFragment())
                .commit()
        }
    }

R.id.container - view container, where your fragment will settle.

And after that you can to use adb.

adb shell am start -n com.example.myapplication/com.example.myapplication.MainActivity --es "show_fragment" "StreamListFragment"
