There is only one supported device at play.google.com Device catalog

Question

There are similar titles like "zero devices compatible" or "one device compatible". But problems are different for all of them.

How can i fix it?

AndroidManifest.xml :

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.appdevelopment.myapp">

<uses-feature
    android:name="android.software.leanback"
    android:required="true" />

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

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:ignore="GoogleAppIndexingWarning,MissingTvBanner">

    <receiver android:name="com.appdevelopment.myapp.MyAppWidget">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>

        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/myapp_widget_info" />
    </receiver>

    <activity
        android:name="com.appdevelopment.myapp.MainActivity"
        android:theme="@style/Theme.Transparent"
        android:excludeFromRecents="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LEANBACK_LAUNCHER" />
        </intent-filter>
    </activity>
</application>
</manifest>

It is a simple countdown widget app

app gradle :

I think everything is normal here.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
    applicationId "com.appdevelopment.myapp"
    minSdkVersion 17
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
