rockscout's Issues

Rockscout shows nothing but black screen when unlock the screen after launching from headunit

Preconditions:
Device : SM-G950
OS : P OS

reproduce procedure:
0. Rockscout launcher fragment is already on top (previously launched)

1. setup the pattern lock on device
2. connects mirrorlink with headunit when device is locked
3. start rockscout
4. unlock the pattern lock

Expected result :
Showing launcher fragment with available application icons

Actual result :
show only black screen

Doing this procedure in P OS, it doesn't relaunch the application, so rockscout goes to states like thsi:
12-03 17:22:40.297 D 18490 18490 com.carconnectivity.mlmediaplayer.ui.MainActivity: onCreate
12-03 17:22:40.381 D 18490 18490 com.carconnectivity.mlmediaplayer.ui.MainActivity: onResume
12-03 17:22:40.409 D 18490 18490 com.carconnectivity.mlmediaplayer.ui.MainActivity: onPause
12-03 17:22:40.526 D 18490 18490 com.carconnectivity.mlmediaplayer.ui.MainActivity: onStop

//after unlocked
12-03 17:22:44.231 D 18490 18490 com.carconnectivity.mlmediaplayer.ui.MainActivity: onResume

I found the mLauncherFragment of MainActivity was not prepared to be drawn in screen after unlocked.
When I tested it by replacing just fresh mLauncherFragment inside of openLauncher function,

public void openLauncher(View caller) {
     if (mLauncherFragment == null)
         mLauncherFragment = LauncherFragment.newInstance();
+    else
+        mLauncherFragment = LauncherFragment.newInstance();
     switchFragment(mLauncherFragment);
 }

it shows the message ("You have no MediaBrowser compatible media pplication ....") because is is not considered to sync with provider. anyway, old mLauncherFragment was not valid at that time.

For android phone, if it's in Recovery mode,can mirror to car by mirrorlink ?

Rockscout not working on S9

Hi there, i've been trying to get rockscout working on my new Galaxy S9 in my Toyota C-HR.
I activate mirrorlink and connect the phone, I can start rockscout on my car's display it launches but then it shows me all the available music apps greyed out with a plug icon next to them.
When I click on an app (ie Spotify) a message pops up which tells me that my phone must be connected to a mirrorlink enabled headunit. "Funny", as it is displaying the message on a the display of my car.

So I'm kinda going round in circles, any help or suggestions would be REALLY appreciated!

Does not the higher android gradle version support?

android gradle version 3.0.1 does not generate mirror link certificates.

what is "android media browse service"?

how to solve this problem?
