If you have an application that you want to run in the background, there are several things you need to do. For one, you need to make sure that your app doesn’t use up system resources or take up too much memory. You also need to consider the impact of allowing it to run in the background on battery life.
When an application transitions from the foreground to the background, the system terminates it to free up any shared resources that it was holding (for example, the camera or a shared database). However, you need to release those resources before your app transitions to the background so that it doesn’t consume them again when it returns to the foreground.
This can be particularly important when an application is storing data that’s accessible by other apps, like images and named objects. It’s best to check with the framework that supports the resource your app is accessing to see if there are any guidelines about what you should do when it’s in the background.
The first step is to create a service that will handle your application’s work requests when it’s in the background. To do this, you need to create an IntentService class and then send work requests to it with an Intent object.
Once you have your IntentService class, you can add a method to your application that calls the service when a request is sent to it. The method should be called with an Intent object to indicate the type of work that the request requires.
You can do this with a few lines of code in your Application class. You need to add a new method called onHandleIntent(), and then send a callback to the service when an Intent object is received.
Next, you need to modify your IntentService so that it is able to receive multiple requests at the same time. For example, if you want to receive a notification from an event on your device when the service is running in the background, add a method that will accept an Intent object with a specific flag to indicate the type of work that the request is for.
Finally, you need to remove any sensitive information from the Intent object so that it doesn’t get saved in your app’s preservation archive when it is in the background. This will prevent your app from saving sensitive information on a device that is in the process of being restored to factory defaults or wiped clean.
This can be especially difficult with Android, since it’s possible for your app to use up a large amount of memory when it is in the background. This can cause problems with your application’s performance, especially if it is a game or media player that constantly uses up RAM storage.
If you have an app that you don’t need to run in the background, you can disable it by going to Settings > Applications. Select the app you want to stop, then click Force Stop. This will permanently stop the app from relaunching when you restart your phone. You can also use the Uninstall button to remove it from your system forever.
