android 关闭数据连接方法

开关数据连接方法：

 Method getITelephonyMethod = null;

		try{

			telephonyManagerClass = Class.forName(telephonyManager.getClass().getName());

		    getITelephonyMethod = telephonyManagerClass.getDeclaredMethod("getITelephony");

	    getITelephonyMethod.setAccessible(true);

	    ITelephonyStub = getITelephonyMethod.invoke(telephonyManager);

	    ITelephonyClass = Class.forName(ITelephonyStub.getClass().getName());
if (mobileFlg) {

				dataConnSwitchavenue = ITelephonyClass

						.getDeclaredMethod("enableDataConnectivity");

				Settings.System.putInt(context.getContentResolver(),

						Settings.System.GPRS_CONNECTION_SIM_SETTING, true ? 1

								: 0);

			} else {

				dataConnSwitchavenue = ITelephonyClass

						.getDeclaredMethod("disableDataConnectivity");

				Settings.System.putInt(context.getContentResolver(),

						Settings.System.GPRS_CONNECTION_SIM_SETTING, false ? 1

					: 0);

			}
dataConnSwitchavenue.setAccessible(true);

	    dataConnSwitchavenue.invoke(ITelephonyStub);

		}catch (ClassNotFoundException e) {

			e.printStackTrace();

		}catch (NoSuchMethodException e){

			e.printStackTrace();

		}catch (IllegalAccessException e) {

			e.printStackTrace();

		}catch (InvocationTargetException e){

			e.printStackTrace();

		}

获取数据连接状态：

public boolean getMobileState() {

		boolean isEnabled = false;

		if(telephonyManager.getDataState() == TelephonyManager.DATA_CONNECTED){

		      isEnabled = true;

		    }else{

		      isEnabled = false; 

		    }   

		return isEnabled;

	}
