broadcastreceiver

I have scheduled alarm for my application. I have implemented broadcast receiver to be triggered once the alarm time reaches. How to manually call broadcast receiver to execute the code inside of onReceive method without replicating the code twice. I thought of having the code in utility singleton call and call that method by having util class instance from anywhere. But is that any other way to call that onReceive method directly or else broadcast intent problematically. android:exported="false" //Additional parameter of receiver when defining in manifest file. Another question is what is

In the OnReceive method I have something like this: Bundle bundle=intent.getExtras(); String phonenumber=intent.getStrngExtra(Intent.EXTRA_PHONE_NUMBER); How to chech if the dialing call is still on or the client hanged up the call?

My question is the following: If the user is having the application open and I want to update some results in that view - how can this be done? I was first thinking of registering this activity as a listener on whatever the BroadCastReceiver recieves. However, this must then be a static list of listeners, as a new instance of the BroadcastReceiver will be set up - but maybe this is not the way to do

i have one activity Main.java is open in my application, i want to close the activity using broadcast receiver , how to close the activity? Firstly your Main.java needs to be registered as a receiver. You could register it in Main.java's onResume(): @Override public void onResume() { registerReceiver(broadcastReceiver, new IntentFilter(BroadcasterClassName.NAME_OF_ACTION)); } Then handle the broadcast and finish your activity: private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals
