Why is the application published on Google Play not installed?

Question

Android

Hello community!
Faced such a problem today. We downloaded the application, published it on Google Play, when I try to install it, an error pops up: "You need to sign in to your Google account." I also noticed a message on the application page: "The application is incompatible with your device." My device 4 is some other lolipop!
The manifest is elementary:

<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="22"/>

<application android:allowBackup="true"
             android:icon="@drawable/ic_launcher"
             android:label="@string/app_name"
             android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
</application>

<uses-permission android:name="android.permission.CALL_PHONE"/>

What could be my problem?
Thanks
