I want to start an activity but strange enough I couldn't find a single place that tells where exactly should I do that.
Here is my code:
@Override public void onCreate() {
super.onCreate();
SoLoader.init(this, /* native exopackage */ false);
initializeFlipper(this); // Remove this line if you don't want Flipper enabled
Intent service = new Intent(getApplicationContext(), MyTaskService.class); Bundle bundle = new Bundle();
bundle.putString("foo", "bar"); service.putExtras(bundle);
getApplicationContext().startService(service);
}
You can use Android Lifecycle component to detect if app is going to background.
Please refer the below code :
import android.app.Application
import android.arch.lifecycle.ProcessLifecycleOwner
class SampleApp : Application() {
private val lifecycleListener: SampleLifecycleListener by lazy {
SampleLifecycleListener()
}
override fun onCreate() {
super.onCreate()
setupLifecycleListener()
}
private fun setupLifecycleListener() {
ProcessLifecycleOwner.get().lifecycle
.addObserver(lifecycleListener)
}
}
SampleApp is just an Android Application, declared in the manifest like:
<application
android:name=".SampleApp"/>
Code for lifecycleListner :
class SampleLifecycleListener : LifecycleObserver {
@Inject
var component: MyLifecycleInterestedComponent
@OnLifecycleEvent(Lifecycle.Event.ON_START)
fun onMoveToForeground() {
component.appReturnedFromBackground = true
}
@OnLifecycleEvent(Lifecycle.Event.ON_STOP)
fun onMoveToBackground() {
}
}
In onMoveToBackground() method you can write your code.
