Android 5.0以上移动网络开关

Android 5.0以前使用ConnectivityManager通过反射两个方法setMobileDataEnabled和getMobileDataEnabled来控制移动网络开和关。  Android 5.0以后使用TelephonyMananger类通过反射获取setDataEnabled和getDataEnabled类完成操作。  注意：需要使用系统权限:android:sharedUserId=”android.uid.system”。

我插一句 跳转到移动数据设置界面 if (SDK_INT <= 19) { GprstrafficManager.setMobileData(mContext, false); } else { startActivity(new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS)); }

public void setMobileDataState(Context context, boolean enabled) { TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); try { Method setDataEnabled = telephonyService.getClass().getDeclaredMethod("setDataEnabled",boolean.class); if (null != setDataEnabled) { setDataEnabled.invoke(telephonyService, enabled); } } catch (Exception e) { e.printStackTrace(); } } public boolean getMobileDataState(Context context) { TelephonyManager telephonyService = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); try { Method getDataEnabled = telephonyService.getClass().getDeclaredMethod("getDataEnabled"); if (null != getDataEnabled) { return (Boolean) getDataEnabled.invoke(telephonyService); } } catch (Exception e) { e.printStackTrace(); } return false; } 1 <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" /> 1234567891011121314151617181920212223242526 1234567891011121314151617181920212223242526

自适应Android5.0以前及以后的代码：

TelephonyManager mTelephonyManager = (TelephonyManager)context .getSystemService(Context.TELEPHONY_SERVICE); ConnectivityManager mConnectivityManager =(ConnectivityManager)context .getSystemService(Context.CONNECTIVITY_SERVICE); 12 12 public void setDataEnable(){ Object object = Build.VERSION.SDK_INT >= 21 ? mTelephonyManager : mConnectivityManager; String methodName = Build.VERSION.SDK_INT >= 21 ? "setDataEnabled" : "setMobileDataEnabled"; Method setMobileDataEnable; try { setMobileDataEnable = object.getClass().getMethod(methodName, boolean.class); setMobileDataEnable.invoke(object, true); } catch (Exception e) { e.printStackTrace(); } } 1234567891011 1234567891011 public void checkConnectState(){ while(true){ Object object = Build.VERSION.SDK_INT >= 21 ? mTelephonyManager : mConnectivityManager; String methodName = Build.VERSION.SDK_INT >= 21 ? "getDataEnabled" : "getMobileDataEnabled"; Method getMobileDataEnable; boolean isDataEnabled = false; try { getMobileDataEnable = object.getClass().getMethod(methodName, null); isDataEnabled = (Boolean) getMobileDataEnable.invoke(object, null); } catch (Exception e) { e.printStackTrace(); } if(isDataEnabled){ break; }else{ sleep(200); } } } 1 2345678910111213141516171819 12345678910111213141516171819
