android: 最容易broadcast sample

				//某个Activity某个按钮里发出broadcast				Intent intent = new Intent("test_broadcast");				sendBroadcast(intent);

		<!-- manifest的application里 -->		<receiver android:name=".MyBroadcastReceicer">			<intent-filter>				<action android:name="test_broadcast"></action>			</intent-filter>		</receiver>
