Signed apk has 0 compatibility in google play store

Question

I've been working on a project for some time now and I pretty much finished and am ready to release it to the play store. I was able to deploy my app through debug mode via the USB cable onto my Samsung s4 phone. Strangely, when I generated the signed apk and released it to the play store, I can't download it on my phone... This makes no sense since I was able to use it when I was testing it... I asked my friends and they experienced the same thing. I looked at my developer console and it says my app is compatible with LITERALLY 0 phones in the market... So I looked it up and I thought maybe my manifest is messed up, so here it is (I'm using android studio btw):

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="XXXX">

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.READ_CONTACTS" />

<uses-feature android:name="android.hardware.CAMERA"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/logo"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:name="android.support.multidex.MultiDexApplication"
    >
    <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
    <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
    <activity
        android:name="XXXX"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
        android:screenOrientation="portrait"
        >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="com.google.android.gms.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:theme="@android:style/Theme.Translucent" />

    <activity android:name="com.facebook.FacebookActivity"
        android:configChanges=
            "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:theme="@android:style/Theme.Translucent.NoTitleBar"
        android:label="@string/app_name" />

    <provider android:authorities="com.facebook.app.FacebookContentProviderXXXX"
        android:name="com.facebook.FacebookContentProvider"
        android:exported="true" />
</application>

</manifest>

So I see no issues in the manifest (maybe someone can correct me on that) and if there were it wouldn't have ran on my phone when I tested the app.

So I use a lot of external libraries for my app, here is the list:

1) facebook api 2) twitter api 3) snapdragon 4) google play service

I also had to use multidex (as you saw in the manifest) because the code exceeded 64k lines of code. Here's how the build.gradle looks like:

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "xxxx"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 3
    versionName "1.2"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
sourceSets { main { java.srcDirs = ['src/main/java', 'libs'] } }
 }

 repositories {
     mavenCentral()
    maven { url 'https://maven.fabric.io/public' }
 }

 dependencies {
    compile 'com.android.support:multidex:1.0.0'
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.google.android.gms:play-services:8.4.0'
    compile 'com.facebook.android:facebook-android-sdk:4.+'
    compile('com.twitter.sdk.android:tweet-composer:1.0.2@aar') {
        transitive = true;
    }
 }

I'm totally new with gradle so I'm not sure if it's set up correctly so there maybe issues with the gradle itself or maybe something else. Anyone have any suggestions what I can do?

Answer 1

I changed the camera feature to required false in the manifest and that did the trick. When I uploaded the apk in the developer console it said 8k+ devices supported. Also the manifest was inccorect, when you put the use-features tag make sure to have camera all lowercase not uppercase like I had.
