multithreading - Start a service in a separate process android

Question

I want to start a service in a separate process (i.e when I go to my Application manager in the settings and then go to running services, it should show my service in a separate process).

My Android Manifest is as follows:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.timerapp.MainActivity"
        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:name="com.example.timerapp.WorkerThread"
        android:process="com.moizali"></service>
</application>

I am starting the service in my MainActivity so obviously when I kill the application the service shuts down as well. Can anyone tell me how to start the service as a different process.

Answer 1

Check out the process attribute for service in AndroidManifest.xml. You need to change your android:process value to start with a :.

http://developer.android.com/guide/topics/manifest/service-element.html

The relevant section:

If the name assigned to this attribute begins with a colon (':'), a new process, private to the application, is created when it's needed and the service runs in that process. If the process name begins with a lowercase character, the service will run in a global process of that name, provided that it has permission to do so. This allows components in different applications to share a process, reducing resource usage.

The other answer provided doesn't really answer the question of how to start a service in a separate process.

Defining a Process of a Service

The android:process field defines the name of the process where the service is to run. Normally, all components of an application run in the default process created for the application. However, a component can override the default with its own process attribute, allowing you to spread your application across multiple processes.

If the name assigned to this attribute begins with a colon (':'), the service will run in its own separate process.

<service
  android:name="com.example.appName"
  android:process=":externalProcess" />

If the process name begins with a lowercase character, the service will run in a global process of that name, provided that it has permission to do so. This allows components in different applications to share a process, reducing resource usage.
