Uploaded APK to Play Store, got 0 supported devices but no error

Question

I am trying to publish an Alpha version of my app to the Play Store, but I am getting 0 supported devices and it is frustrating as I don't see the bug.

The project is a new style (gradle) and the API declaration and versions are defined in the build.gradle.

You can get the app here https://github.com/Coinomi/coinomi-android

Here is my manifest file:

<?xml version="1.0" encoding="utf-8"?>

    package="com.coinomi.wallet"
    android:installLocation="internalOnly" >

        <service
            android:name=".service.CoinServiceImpl"
            android:exported="false" />

    </application>

</manifest>

I you have an idea please help because I am stuck from yesterday.

Thanks!

Answer 1

I've got the same issue. The problem was in uses-feature. In my manifest.xml I have

<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />
<uses-feature
    android:name="android.hardware.camera2"
    android:required="true" />

The solution was to change to

<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />

Since I've marked both camera and camera2 as required and no devices have both of them I was having 0 supported devices.

Answer 2

Finally it was a dependency compile 'com.lambdaworks:scrypt:1.4.0' that was causing the issue.

If you stumble upon this issue, check if in the APK DETAILS dialog in Google Play if you have:

Native platforms x86_64

This was, I think, the problem because when I removed the dependency, the x86_64 part was removed and got 6814 supported devices.

UPDATE

The root of the problem was that the dependency had native precompiled .so libraries but none for Android. I had to recompile with NDK from source for the platforms: armeabi-v7a and armeabi
