Android auto APP not showing in pyshical device (is not listed in Android Auto app list) but works fine in DHU

I currently have an app on the Play Store and have created a version for Android Auto.
The Android Auto version works correctly on the DHU (Desktop Head Unit).
To test it on a real device (vehicle), I have created an Internal Test in Play Store, and in it, I have added the original app together with the Android auto bundle.
When I install it from the Play Store, the app does not appear in the list of available for Android Auto.
I suppose it has to do with the configuration of my "manifest" files, but I don't see where the error could be.
Has anyone had the same problem?
--- CODES UPDATED AFTER FIRST ANSWER -----
This is the "manifest" of the Android Auto app.

I have tested with and without <uses-permission and uses-feature in the Android Auto app, but ever the same result, no way to launch it in the car, because is not available in the android auto list.
Thanks in advance.

Can you add the contents of the automotive_app_desc.xml file? Also, you should declare the minimum Car App API level as a <meta-data> element in the manifest.

I am getting the below two error messages and please can someone help me as I am struggling to generate a singed APK. I am able to build my app, however, when trying to create a API I always get the two error messages indicated below.
Error:Execution failed for task
':mobile:transformClassesWithDexForRelease'.
com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException:
java.util.concurrent.ExecutionException:
com.android.dex.DexIndexOverflowException: method ID not in [0,
0xffff]: 65536

The error:
\AndroidManifest.xml Error:(48) Error: The element must be a direct
child of the root element [WrongManifestParent] Error:Execution failed
for task ':mobile:lintVitalRelease'.
This indicates that you need to look at line 48 of your manifest.xml
That line looks like:
<application
android:name=".ApplicationState"
android:label="#string/app_name" />
That's a second xml <application> tag.
It tells you that tag must be a direct child of the root.
Probably just remove it and it will work.

Remove this
<application
android:name=".ApplicationState"
android:label="#string/app_name" />
and add this
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<application
**android:name=".ApplicationState"**
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:name=".FallDetectorSettings.SettingValues"
android:label="#string/app_name"
android:screenOrientation="portrait"
in your gradle (app) inside android{} place this
lintOptions {
checkReleaseBuilds false
}
for dex error follow the solution given by android in the below link:
https://developer.android.com/studio/build/multidex.html

Android - No launcher icon after installing apk

I know that this question has been asked many times, but the old answers don't resolve my issue, maybe something has changed.
Why there is no launcher icon after installing the apk?
This is the manifest.xml

<activity

What is the problem? Please Guide.

App icon should be in minmap like this
minmap-mdpi/ic_launcher
minmap-hdpi/ic_launcher
minmap-xhdpi/ic_launcher
minmap-xxhdpi/ic_launcher
minmap-xxxdpi/ic_launcher
not in Drawable, so please change it. and also check icon size.

As I've read here, here and here, I've done :
1) copied all the drawables from #android/drawable to my corresponding folders hdpi, mdpi, e.t.c -
so I havn't any icon from #android/drawable folder in the project
2) put the icon drawable to the drawable folder of the res
3) cleaned the project
What can be solution for this ?

I think it is linked to having the icon attribute setting to a color #android:color/transparent. Maybe try a transparent drawable rather than a color.

I've found the solution - it was in
<activity
....
android:icon="#android:color/transparent" - the problem string
...
</activity>
when I removed that string, everythins worked fine

App dont show in market for tablets

What do I need to add?
BR

android:name="android.permission.WRITE_EXTERNAL_STORAGE"
That's your problem there. Some/most tablets don't have external storage. Either use internal storage (in which case you don't need a permission), or try adding android:required="false" to your WRITE_EXTERAL_STORAGE permission. Either way though, you are going to have to go into your code where you are writing to external storage and change it to internal, or handle the case where a tablet doesn't have external storage.
