Monitor and handle Android system broadcasts.
The application can use broadcast receivers to monitor system events from the Android OS as well as custom broadcasts sent by other applications. The application will need to know the name of the broadcast actions in order to monitor them. Note that Titanium only supports programmatically creating and registering broadcast receivers. Titanium does not support declaring a receiver in the Android manifest.
To create a Broadcast Receiver, use the Titanium.Android.createBroadcastReceiver method.
Specify either a callback to handle the broadcast with the onReceived
property or a
JavaScript file with the url
property. Do not specify both. If both properties are
used, the url
property takes precedence.
To start listening to a broadcast, pass the BroadcastReceiver
object and an array of
broadcast actions to listen for to the Titanium.Android.registerBroadcastReceiver method.
Titanium exposes some of the system-level broadcasts as the Titanium.Android.ACTION_*
constants. Note that some of these constants are not broadcast messages.
You can also define a custom broadcast action. Use a reverse domain name scheme in order to avoid potential conflicts with other applications.
To stop listening to a broadcast, pass the BroadcastReceiver
object to the
Titanium.Android.unregisterBroadcastReceiver method.
To monitor a broadcast that requires a special permission, declare the <uses-permission>
element in the Android manifest section of the tiapp.xml
file for each broadcast that uses
a special permission. For example, to monitor the NEW_OUTGOING_CALL
broadcast, the
application needs to add the following permission:
<ti:app>
<android>
<manifest>
<uses-permission android:name="android.permission.NEW_OUTGOING_CALL" />
</manifest>
</android>
</ti:app>

This example creates a broadcast receiver and registers it to handle the airplane mode broadcast.
var bc = Ti.Android.createBroadcastReceiver({
onReceived: function() {
Ti.API.info('Handling broadcast.');
}
});
Ti.Android.registerBroadcastReceiver(bc, [Ti.Android.ACTION_AIRPLANE_MODE_CHANGED]);
The name of the API that this proxy corresponds to.
The name of the API that this proxy corresponds to.
The value of this property is the fully qualified name of the API. For example, Button
returns Ti.UI.Button
.
Indicates if the proxy will bubble an event to its parent.
Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.
Default: true
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.
The function called when a broadcast is received.
The function called when a broadcast is received.
URL of the JavaScript file to handle the broadcast.
URL of the JavaScript file to handle the broadcast.
Adds the specified callback as an event listener for the named event.
Name of the event.
Callback function to invoke when the event is fired.
Applies the properties to the proxy.
Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that myproxy[key] = value.
A dictionary of properties to apply.
Fires a synthesized event to any registered listeners.
Name of the event.
A dictionary of keys and values to add to the Titanium.Event object sent to the listeners.
Removes the specified callback as an event listener for the named event.
Multiple listeners can be registered for the same event, so the
callback
parameter is used to determine which listener to remove.
When adding a listener, you must save a reference to the callback function in order to remove the listener later:
var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);
To remove the listener, pass in a reference to the callback function:
window.removeEventListener('click', listener);
Name of the event.
Callback function to remove. Must be the same function passed to addEventListener
.
Sets the value of the bubbleParent property.
New value for the property.
Sets the value of the lifecycleContainer property.
New value for the property.
Sets the value of the onReceived property.
New value for the property.
