How to solve the problem with starting an Android App on Boot?

I've just read a ton of similar questions, but nothing helped at all.

In the code below I'm trying to perform a starting an app right after unlock of my granny's old phone and show her the only button to enter Viber.

OnBoot Activity

class OnBoot : BroadcastReceiver() {  override fun onReceive(context: Context, intent: Intent) {      if (Intent.ACTION_BOOT_COMPLETED == intent.action) {          val i = Intent(context, MainActivity::class.java)          i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)          context.startActivity(i)      }  }  

Manifest

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />              <receiver android:name=".OnBoot">          <intent-filter>              <action android:name="android.intent.action.BOOT_COMPLETED" />              <action android:name="android.intent.action.QUICKBOOT_POWERON" />          </intent-filter>      </receiver>  </application>  

MainActivity

fun openApp(view: View) {      val launchIntent = packageManager.getLaunchIntentForPackage(".com.viber")    if(launchIntent != null){      startActivity(launchIntent)  } else {      Toast.makeText(this , "No package", Toast.LENGTH_LONG).show()  }  

So, app doesn't start even on Emulator. Seen comments like "Check weird permission on Xiomi emulator", mine is Pixel 2. Also, I know that Viber package name is wrong and I know where it should be, but cannot find it in emulator, would appreciate the hint in comments.

Maybe any ideas with the task?
