Two same icons for one application after run

I am developing an Automotive OS Media app, but for my project, I always get two same icons on my emulator after running. Since my project is an Automotive OS app, there is no android.intent.action.MAIN and android.intent.category.LAUNCHER - I mean, there is no duplicates of them to cause my problem.
My project has two modules - one is Automotive application, another one is Media Service Library (named common). Below are AndroidManifest.xml and build.gradle files for two parts.
AndroidManifest.xml (automotive)

Android automotive platform is showing two icons because your application has two MediaBrowserService(AutomotiveMusicService and MusicService).
The automotive platform scans for Media application installed in the platform based on intent-filter"android.media.browse.MediaBrowserService", hence two icons.

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.google.firebase:firebase-iid:19.0.0]

On including implementation 'com.google.firebase:firebase-core:17.0.0'
in my build.gradle(app) my project does not successfully sync.
i've tried cleaning up the project i've tried ,as the error suggests, increasing minSdkVersion to 16 (it gives another error) but nothing worked.

I just started developing on Android and got that same error. I changed my minSdkVersion from 15 to 16, and then it built and ran.

I'm not an expert but I had the same problem just now and I went to the app folder in android mode right-clicked it and entered 'open module settings'.In the 'default config' I set the minSDK to the versions I have installed

Got the same problem just fix it by migrating the project to androidx
Click on the Refactor tab->Migrate to androidx->Just give a backup directory->click again Refactor
Hope this will clear the same

Apk doesn't work after changing compileSdkVersion to android-P

It's really strange, I created a new empty project and then I changed in file settings compileSdkVersion from 27.1 Oreo to android-P, then I refactored app to AndroidX and it's working fine if I run it on emulator or via adb connect with my device. But when I try to build apk and install it on my phone here's problem appear - 'App not installed'. But before I changed compileSdkVersion apk installs fine.
Manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="ru.scapegoats.myapplicationmmmm">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"

android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

You cannot install app with compileSdkVersion 'android-P' preview version on older OS.
Since beta release for Android P is out, change compileSdkVersion to 28:
compileSdkVersion 28
Note: Ensure you have internet connection so that proper SDK updates can be downloaded.

My Android mobile app Installation failed on Android version4.4.4

My Android mobile app is successfully installing only on android version 6.0.1 but I want to install it on android version 4.4.4. What changes I have to do?
Here in my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
