How to determine whether Android's Service has been started or bound

To determine whether an Android Service has been started or bound, you can use the following method:

Start status judgment:

You can use the getRunningServices() method in the ActivityManager class, which returns a List<ActivityManager.RunningServiceInfo> object that contains information about all services currently running. This list can then be traversed to find if any of the target services have been started.

Here is a sample code:

val manager = getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager
val runningServices = manager.getRunningServices(Integer.MAX_VALUE)

for (service in runningServices) {
    if ("com.example.myapp.MyService" == service.service.className) {
        // MyService 已经启动
        break
    }
}

Binding status judgment:

You can use the bindService() method in the Context class to bind the service. If the binding is successful, it means that the service has been started and bound.

Here is a sample code:

val intent = Intent(this, MyService::class.java)
val isServiceBound = bindService(intent, mConnection, Context.BIND_AUTO_CREATE)

if (isServiceBound) {
    // MyService 已经启动并且已经绑定
}

Among them, mConnection is a variable of ServiceConnection type, used to handle the callback method of the bound service. Corresponding processing needs to be performed in the onServiceConnected() method, such as saving the instance of the service, etc.

The above are two methods to determine whether the Android Service has been started or bound. You can choose which method to use based on specific needs.
