Manifest name attribute of <service> tag

Question

According to documentation in manifest element

<service android:name=".PrinterService" 

should be specifried name of the Service subclass. My subclass is named PrinterService and is defined as following

package arrowsys.vrp.print;

#import
public class PrinterService extends Service {
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    public class PrinterSession extends PrinterDiscoverySession {
    }
}

When I put into attribute name .PrinterService I get

Cannot resolve symbol

With value .service.PrinterService I get

AidleType package expected, got '.'

Edit: to make it more simple, I have deleted folder arrowsys.vrp.printer/service so my PrinterService.java is directly in arrowsys.vrp.printer.

Now the package definition is package arrowsys.vrp.print ;

Complete AndroidManifest.xaml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="arrowsys.vrp.print">
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        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>
        <service
            android:name="arrowsys.vrp.print.PrinterService"
            android:description="@string/app_name"
            android:permission="android.permission.BIND_PRINT_SERVICE" >
            <intent-filter>
                <action android:name="android.vrp.print.PrinterService" />
            </intent-filter>
        </service>
    </application>
</manifest>

Answer 1

As per App Manifest Documentation you have to include the full package path or your service should be a child of the application package

If you define a subclass, as you almost always would for the component classes (Activity, Service, BroadcastReceiver, and ContentProvider), the subclass is declared through a name attribute. The name must include the full package designation. For example, a Service subclass might be declared as follows:

<manifest . . . >
<application . . . >
    <service android:name="com.example.project.SecretService" . . . >
        . . .
    </service>
    . . .
</application>

However, if the first character of the string is a period, the application's package name (as specified by the element's package attribute) is appended to the string.

<manifest package="com.example.project" . . . >
<application . . . >
    <service android:name=".SecretService" . . . >
        . . .
    </service>
    . . .
</application>

My guess would be that your Manifest package is not arrowsys.vrp.print , so you'll have to use <service android:name="arrowsys.vrp.print.service.PrinterService">
