Google Play Store - Find out why a device is incompatible - android

I published an android app in google playstore. Some clients complain about not being able to download the app as the play stores says it is "not compatible".
In google developer console, I can only see THAT a device is not supported. I want to know WHY a device is incompatible but that information is hidden from me.
Google has to have this information to determine compatibility, why is there no way to show this information to developers? Or am I wrong?
We'd really appreciate that feature, it is vital I think.
One device that fails, is for example: medion lifetab e10315

I have a problem.
I have a signed apk generated and installed but
I can't start the App from installing and I can't see it in the app menu.
I can only see it in the settings app menu.
Why cant I see it or starting?
The app can be started via the debugger.
Can you help me?
The operating system is Android 7 and 5.

Update
i found the problem, it was android:mimeType but why?
Can you explain it to me?

You probably forgot launch mode. Write this in your AndroidManifest.xml inside application element
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
replace .MainActivity with your activity name

anyone has an idea whats wrong with this ? I have tried changing uses-permission to permission, where it had C2D_ it didn't work.

You may refer with this post.
Remove
<uses-permission android:name="${applicationId}.permission.C2D_MESSAGE"/>
<permission
android:name="${applicationId}.permission.C2D_MESSAGE"
android:protectionLevel="signature"/>
Run App then add the permisson again and Run App.
This problem often occurs when you try to install debug and release version of your app on the same device.

I just trying to publish my android app, I signed my application from my keystore, but Google Play console displaying me supported devices is zero. I am using Android SDK only for my app. Any reason why this so ??

Missing a char 'd' in uses-feature android:name="android.harware.telephony"

I looked up all possibilities for this to be happening, but found no solution. The size of my apk is 7MB, size of the app goes upto 10Mb after installation. I have no bulky files in Raw folder, i have no raw folder at all for that matter. There are no features with requires-true. support all densities is true. support all screens is true. Even then, my app is not listed when searched from some devices, and incompatible on a few other. Why is this happening?

may be you are using fragments some where like in google maps that you used, which make your app incompatible because it does not supported by api version 8.see here for api < 11.
Android - Fragment API for API level < 11
if you are using fragments only in google maps , then you can use supportfragment.
read here too.

I have hosted my app on the Google Play Store. Most phones can go to the store and download it successfully. Certain phones can not see the listing, these phones are running Android 2.3.6.
I've a feeling that the target api in the manifest may have something to do with it?
This is what i have in my manifest.
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="11" />
.
All the phones on 4.x are fine.
Why can't lower Android phones see the listing?
Thanks.

NFC was added in API Level 10. More importantly, few API Level 10 and below devices have NFC hardware. You are requiring that devices have NFC hardware; ergo, you will not have very many API Level 10 and below devices that support your app.
If you do not absolutely need NFC to function, use android:required="false", and check for NFC availability at runtime, either via PackageManager and hasSystemFeature(), or just whether you can get your NfcAdapter.
In addition:
You will only be available for devices that have Maps V1, and I would imagine that some newer devices will start dropping support for that, since Maps V1 has been deprecated for a year.
You are wasting CPU and memory with those :remote receivers
There is no PREVENT_POWER_KEY permission in Android
