How to execute a remote service

I have a service MyService.java in Application "ServiceDem开发者_JAVA技巧o". The manifest of this application looks like this

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.moto.dev"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Sample"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <service android:enabled="true" 
                 android:name=".MyService" 
                 android:permission="syh.permission.STARTMYSERVICE">
        </service>
      </application>
       <permission
        android:protectionLevel="normal"
        android:label="Start My Receiver"
        android:description="@string/startMyActivityDesc" 
        android:name="syh.permission.STARTMYSERVICE">
       </permission>
    <uses-sdk android:minSdkVersion="8" />

</manifest> 

I have another application "CallerService" manifest looks like this

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.moto.dev"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".CallerService"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>

    <uses-permission android:name="syh.permission.STARTMYSERVICE"></uses-permission>
    <uses-sdk android:minSdkVersion="8" />

"src/com/moto/dev/Sample.java"</manifest> 

I have an activity from where I m trying to start the service on the click of the button

Intent intent = new Intent();
//path where my service is located in application "ServiceDemo"
intent.setClassName("com.moto.dev","com.moto.dev.MyService");
startService(intent);

This fails to work. Says "unable to start service intent" May I know where I am going wrong.

and to my wonder, there comes this SecurityException: Not allowed to start service Intent without permission syh.permission.STARTMYSERVICE while it has been explicitly granted!!

As your service doesn't have an intent filter, you will need to set exported flag to true in your service in manifest
