I am using deep link, launchMode="singleTask". If there is an instance of my activity everything works fine: only onNewIntent is called. But if there is no instance, firstly onCreate is called, then onNewIntent and again onCreate. That is why, the screen flickers. What is the problem? I removed all code, and only logged the events. But the same behavior is observed.

android:name="uz.avtobank.MainActivity"

android:configChanges="keyboardHidden|orientation|screenSize"

android:launchMode="singleTask"

android:screenOrientation="nosensor"

android:theme="@style/SplashActivityTheme"

android:windowSoftInputMode="adjustResize|stateHidden">

override fun onCreate(savedInstanceState: Bundle?) {

super.onCreate(savedInstanceState)

setTheme(R.style.AppTheme)

setContentView(R.layout.activity_main)

val host = NavHostFragment.create(R.navigation.nav_graph_main)

supportFragmentManager.beginTransaction()

.replace(R.id.container, host)

.setPrimaryNavigationFragment(host)

.commit()

logMessage("onCreate ${intent.action}")

}

@SuppressLint("DefaultLocale")

override fun onNewIntent(intent: Intent?) {

super.onNewIntent(intent)

logMessage("onNewIntent ${intent.action}")

handleIntent(intent)

}

private fun handleIntent(intent: Intent) {

if (intent.action != Intent.ACTION_VIEW)

return

try {

findNavController(R.id.container).handleDeepLink(intent)

} catch (e: IllegalStateException) {

} catch (e: IllegalArgumentException) {

}

setIntent(intent)

}

The following appears on the log:

There is instance: onNewIntent

There is no instance: onCreate, onNewIntent, onCreate

The same happens evene if I remove handleIntent method.
