Why Run Apps in Background?
Running apps in the background offers several benefits, including:
- Improved Productivity: By running apps in the background, users can multitask and perform multiple tasks simultaneously without interruption.
- Enhanced Convenience: Background apps can provide users with instant access to frequently used features, such as notifications, maps, and camera controls.
- Increased Battery Life: Running apps in the background can help extend battery life by reducing the need for frequent reboots and power cycles.
How to Run Apps in Background on Android
To run apps in the background on Android, you need to use the Background Execution Service (BES). Here’s a step-by-step guide to help you get started:
Step 1: Enable BES
To enable BES, follow these steps:
- Go to Settings: Open the Settings app on your Android device.
- Select System: Scroll down and select System.
- Select Advanced: Tap on Advanced.
- Select BES: Tap on Background Execution Service.
Step 2: Create a Service
To run an app in the background, you need to create a Service. Here’s how to do it:
- Create a new Service: In the System app, create a new Service by tapping on Create Service.
- Choose a Service Name: Enter a name for your service, such as "BackgroundApp".
- Set the Service Intent: Set the Intent for your service, which should be a ServiceIntent with the following properties:
- android:name: Set the name of your service to "BackgroundApp".
- android:exported: Set the exported property to true.
Step 3: Register the Service
To register your service, follow these steps:
- Create a new Intent: In the System app, create a new Intent for your service.
- Set the Intent: Set the Intent to be executed by your service, which should be a ServiceIntent with the following properties:
- android:name: Set the name of your service to "BackgroundApp".
- android:exported: Set the exported property to true.
- android:startActivity: Set the startActivity property to false, as your service will not start an activity.
Step 4: Start the Service
To start your service, follow these steps:
- Create a new Activity: In the System app, create a new Activity.
- Set the Service: Set the Service to be executed by your activity, which should be a ServiceIntent with the following properties:
- android:name: Set the name of your service to "BackgroundApp".
- android:exported: Set the exported property to true.
- android:startService: Set the startService property to true, as your service will start a new instance.
Example Code
Here’s an example code to demonstrate how to run an app in the background on Android:
// BackgroundApp.java
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
public class BackgroundApp extends Service {
private static final Binder binder = new Binder(this);
private static final int REQUEST_CODE = 1;
@Override
public IBinder onBind(Intent intent) {
return binder;
}
@Override
public void onCreate() {
super.onCreate();
// Start the background service
Intent serviceIntent = new Intent(this, BackgroundApp.class);
serviceIntent.putExtra("REQUEST_CODE", REQUEST_CODE);
startService(serviceIntent);
}
@Override
public void onDestroy() {
super.onDestroy();
// Stop the background service
stopService(serviceIntent);
}
}// BackgroundAppService.java
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
public class BackgroundAppService extends Service {
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
// Start the background service
Intent serviceIntent = new Intent(this, BackgroundApp.class);
startService(serviceIntent);
}
@Override
public void onDestroy() {
super.onDestroy();
// Stop the background service
stopService(serviceIntent);
}

Tips and Tricks
- Use a Service: Services are the best way to run apps in the background on Android. They provide a way to execute code in the background without blocking the main thread.
- Use a Binder: Binders are used to communicate between the service and the activity that started it. They provide a way to pass data between the two.
- Use a Intent: Intents are used to pass data between the service and the activity that started it. They provide a way to pass data between the two.
- Use a ServiceIntent: ServiceIntents are used to pass data between the service and the activity that started it. They provide a way to pass data between the two.
Conclusion
Running apps in the background on Android is a powerful feature that provides users with instant access to frequently used features. By following the steps outlined in this article, you can create a service that runs an app in the background on your Android device. Remember to use a service, binder, intent, and serviceIntent to communicate between the service and the activity that started it. With these tips and tricks, you can create a powerful background app that provides users with a seamless experience.
