Creating A Service In Android

I'm creating my first android app and I need to use a service. The UI will have a checkbox (CheckBoxPreference) that will be used to turn the service on/off and the service will on

Solution 1:

CheckBoxcheckBox=
    (CheckBox) findViewById(R.id.check_box);
checkBox.setOnCheckedChangeListener(newOnCheckedChangeListener() {

    publicvoidonCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if (isChecked) {
            startService(newIntent(this, TheService.class));
        }
    }
});

And the service:

publicclassTheServiceextendsService {   

    @Overridepublic IBinder onBind(Intent intent) {
        returnnull;
    }

    @OverridepublicvoidonCreate() {
        Toast.makeText(this, "Service created!", Toast.LENGTH_LONG).show();
    }

    @OverridepublicvoidonDestroy() {
        Toast.makeText(this, "Service stopped", Toast.LENGTH_LONG).show();
    }

    @OverridepublicvoidonStart(Intent intent, int startid) {
        Toast.makeText(this, "Service started by user.", Toast.LENGTH_LONG).show();
    }
}

Solution 2:

In Android Studio, right-click package, then choose New | Service | Service. Now add this method:

@OverrideintonStartCommand(Intent intent, int flags, int startId) {
    // Your code here...returnsuper.onStartCommand(intent, flags, startId);
}

Note: onStart is deprecated.

To start the service: From an activity's onCreate method (or a broadcast receiver's onReceive method):

Intent i = newIntent(context, MyService.class);
context.startService(i);
