Google Play - Zero supported Devices, Not able to find app

I have published an app in google play - Smart Eye - Intrusion Catch
The problem however is developer console shows zero supported devices. I am able to search my app in laptop but when searching through any android mobile device i am not able to find my app.
My manifest file look like this -

Any ideas on what is happening wrong here. Thanks in advance

The line
<uses-feature android:name="android.hardware.camera2.full" />
is wrong - the feature name you might be looking for is "android.hardware.camera.level.full".
That said, do you need the capabilities of a FULL-level camera device (see docs for this here)?
It means you want full support of the new camera2 API, with 30fps full-resolution capture, etc.
If you don't need this, then just remove this uses-feature line, or add android:required="false" to the line and fix the feature name.

You are declaring via the uses-feature elements that you only run on devices that have all of the following:
android.hardware.camera
android.hardware.camera.autofocus
android.hardware.camera2.full
camera2 is an API, and not a feature to be declared in the manifest, so you are declaring you must have something that no devices have. Remove this line.

I guess its for permission. There are many permissions.
Try remove unusable ones it will help. May be there are some permissions which not supported by any device play store checks and don't show any device

No internet access in signed APK

I was working on an app that was working fine in the Debug build version and then I created a signed APK using keystore , and then with Android Studio --> Generate SIgned APK.
When I install the signed APK manually by downloading on to my phone, it asks for all permissions including internet access. However post installation, app starts but none of the server calls / API calls are working. The phone has internet connection though (webpages open up in browser)

In my case I found this error on LogCat
Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
So I checked the server certificates in this web to see what happens: https://www.ssllabs.com/ssltest
So should be a server problem

Android App is not visible on Google Play store for tablets

Can anyone suggest me why this app is not visible for tablets on google play store.
I am using GCM, Gmap, Camera and storing files on sdcard.
It is not visible for major tablets on google play store, sim and simless.
I do know that google play store mask app from device which not match with manifest permissions however I believe that there no any permission which is not exist on major samsung devices.

If the Tablet android version below
android:minSdkVersion="11"
Then Google playstore .will not show app in the tablet

android play store is filtering my app from tablets, possibly other devices

I have several versions of an app live on Play, and I'm getting feedback that they don't appear on tablets. I've seen this and this and this, but as you can see they don't seem to apply. I explicitly support all screens and mark telephony as non-required, and I don't use copy protection since my app is free to end users. Can anyone see a problem?

You have included CALL_PHONE permission. Most tablets do not provide this feature and will most likely have them filtered out.
See here for additional info/ideas
android.permission.CALL_PHONE for tablets

After further investigation, it looks like the few users who couldn't find an app were looking for older apps (without
<uses-feature android:name="android.hardware.telephony" android:required="false"></uses-feature>
in the manifest). The new apps seem to be fine. Thanks for the responses.

c2dm returns Application Id as null

I am new to android, i am having issue in implementing push notification.
As stated in a tutorial I read, i registered in c2dm and got Auth token, then registered in UrbanAirShip, with package xxxx, got app key and secret.
My project team used API 2.1 initially, at that time i got AppId through helium transport, both in device and in emulator.
Then we changed API into 2.2, at that time i again registered in c2dm with another sender id, got Auth token, and also again registered in UrbanAirShip with new account,
got key and secret.
For first few tries through c2dm transport, i got AppId, then i got only null, both in device and in emulator with errors as showed below,
I don't know what gone wrong, whether change in API level, or multiple sender id registration in c2dm, or multiple registration in UrbanAirShip for same package name or So many uninstalls.
I have added Manifest file and Application's oncreate method , please guide me to get back AppId.

The problem arises when you run in an emulator. You need to run it in device (and Gmail account should be setup - Else you get an error). Also, it should be 2.2+. Push is only supported on 2.2+ devices. Change the minSDK version to 2.2 and try it in device. It will work.

You need to make sure you are using the "google api" version of the SDK you want, and also to have a valid google account which is market enabled. This is a requirement for c2dm.
