Hello to all, I have read something about how to launch a Activity from BroadcastReceiver, hence now I am reached the point where I really cant not find the answer to... why is closing my application?.
I will explain the idea of the application: It consists of a main screen "main" that has only one ToggleButton, when it changes state to "On" begins my service, when go to "Off" does the same and stops it. This all works fine, I can close the application and service continue running smoothly. I can stop this service when I want, reopening the application and changing the button to "OFF". Now the service "MyService" is waiting any change of your phone, for each change It send a message like a Toast, it helps me to know and check if my service is active, it works perfectly except when you add the code lines to run an Activity that contains simply an image that is where the application is closed, if I leave only the Toast, it is going great, tells me that the phone are ringing and informs the incoming phone number. I create a class that receives the context and try to launch the Activity in question "NewScreen" Here I leave the application code, Any idea? It took me several days and I dont reach any breakthrough.
