I learn tizen app, i try to use sample app - hello accesory.

this is document. but it's so much simple and i can't understand how to run...

https://developer.samsung.com/galaxy-watch/develop/samples/companion/hello-native

this project has 2 part, tizen app and android service.
but i use android service first.

i import(open) project in android studio and connect my phone. but i push 'run' or 'debug' button, this error occur.

Error running 'app'

Default Activity not found

i see a blog, he say 'use build - generate signed apk'. it work. i install to my phone through apk file.
but i can't know it really work. because i install tizen app and try connect, tizen-android connect isn't work....

i think android service is problem or tizen app is problem, but i can't any test on android.

i want how to know service is running now and how to debug in android studio.
lower is androidManifest.xml and source code.

Your app project don't have activity declared,
You need to have activity with this attribute

        <intent-filter>

            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter>

Example:

    <activity

        android:label="@string/app_name"

        <intent-filter>

            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />

        </intent-filter>

    </activity>

You need to declare launch activity for avoid the
