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?

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.

Android - application not found error for some users after update

I have an android app on play store. I just released a new version but some of users report that after update they cant open application because they get application not installed error but they can open application through market by touching on open button. On new version i used same .jks file, I changed AndroidManifest.xml because i wanted to change main activity from .MainActivity to .Landing so mainActivity is no longer main. Maybe problem happens because of that? By the way not all users effected from this problem. Here is old and new AndroidManifest files and could you please check these files? Maybe another row cause that problem?
Solitions;
- Some users restart their phone and it works
- But some users cant fix by restarting their phone, so they remove and install again to fix it
But why this happens to some users?

Your MainActivity is no longer a MAIN/LAUNCHER activity. Are you sure it's not just a matter of old shortcuts disappearing/failing to launch because of this?
The difference between users may be caused by having different launcher apps (various manufacturers or manually installed). If you have some helpful users, you could ask them to:
check the app drawer for the app, and
take a bugreport and send it to you (so that we may be able to see some logs of a failed launch)

Android App not compatible from play store but works in debug mode

The mobile I am going to talk about is Micromax A63, Android Version 4.2.2
When I was developing my app, I used it as a debug device and it worked fine. All the development is done on the system.
After development, I uploaded the apk to play store and registered as a beta tester. When I see the app in the play store it says "Your device is not compatible with this version"
I have checked the compatible list, interestingly this device is neither in Supported Devices List nor in Unsupported list.
I have the following in my gradle build
minSdkVersion 13
targetSdkVersion 22
The permissions i use in the app are
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Help me understand what could be the issue.

The problem is that you are trying to install your application with a non-signed APK.
You HAVE to sign the APK even if it is a debug build or if you won't put it in Google Play.
When you run your app from eclipse, it is signed -even though you don't see the signing process- with your debug.keystore.
ALL apps MUST be signed before you install them on a device. ALWAYS. That suffers no exception.

Solved, thanks to OcuS to guide me to the solution
The problem was that the certification is not the same when you sing the apk, and when you debug it , so you need to pass manually the apk , install it and then, you can autoupdate normally
