App not compatible with your device. ALL devices

Question

After publishing my app, I got the message it's not compatible with my device. even though I test it in the same device. The "error" message is showing for everyone who tries to download the app, like it's not compatible with your device. Folow the Gradle:

    apply plugin: 'com.android.application'
   apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.ths.dev.cadeoprefeito"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'
    implementation 'com.google.android.gms:play-services-maps:15.0.1'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'

    implementation 'com.google.firebase:firebase-ads:16.0.1'
    //FirebaseAUTH
    implementation 'com.google.firebase:firebase-auth:16.0.4'
    //FirebaseStorage
    implementation 'com.google.firebase:firebase-storage:16.0.3'
    //FirebaseUI
    implementation 'com.firebaseui:firebase-ui-storage:0.6.0'
}

the Manifest:

</manifest>

I don't know what i can do. Any help?

Answer 1

don't think android.hardware.camera2 is the reason, which is commonly available on current devices - when not requiring it, one has to provide the legacy camera as a fallback option (with a maps and splash-screen activity, I'd rather wonder for what it shall be good for). the reason is rather: a) add the supports-screens element to the Manifest.xml... because without it, no single screen size is being supported. and b) add apply plugin: 'com.google.gms.google-services' at the bottom of the file.

Answer 2

You should add android:required="false" in android:name="android.hardware.camera2" section.

When you declare android:required="false" for a feature, it means that the application prefers to use the feature if present on the device, but that it is designed to function without the specified feature, if necessary.

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