通过编程切换＆QUOT;限制后台数据和QUOT; [英] Programatically toggle "Restrict Background Data"

问题描述

如果我进入设置 - 数据使用。和preSS的属性我可以激活限制后台数据，使用的是三星Galaxy S2（i9105P）与Android 4.1.2

If I go to "Settings - Data Usage" and press the "Properties" I can activate "Restrict Background Data", using a Samsung Galaxy S2 (i9105P) with Android 4.1.2.

有没有什么办法可以做到这一点编程，无论是上下车？

Is there any way I can do this programatically, both on and off?

我只想要激活/关闭特定条件下（由我的应用程序确定的），所以我不必手动记得来激活它。

I only want to activate/deactivate it under certain conditions (determined by my app) so I don't have to manually remember to activate it.

PS：我搜索了android.developer.com网站，但没有成功。

推荐答案

据我所知对于Android 4.x中你不能做到这一点。只有猴子亚军插件可以帮助你。

As I know for Android 4.x you cant do that. Only monkey runner plugin can help you.

但如果你需要为Android 2.X，这是方法我用：

But if you need for Android 2.x, this is method I used:

/**
 * Switch mobile data network access 
 * */

public void nmSwitchMobileNetworkDataAccess(boolean swtichCellOn){

    boolean disable;
    TelephonyManager telephonyManager = (TelephonyManager)m_context.getSystemService(Context.TELEPHONY_SERVICE);

    if(telephonyManager.getDataState() == TelephonyManager.DATA_CONNECTED){
        disable = false;
    }else{
        disable = true;  
    }

    try{
        final ConnectivityManager conman = (ConnectivityManager)m_context.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
        final Method setMobileDataEnabledMethod = conman.getClass().getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);

        if(disable == true && swtichCellOn == true){
            setMobileDataEnabledMethod.invoke(conman, true);//turn cell on

            DispatcherAndroid.androidObserverItf.androidObserver_OnProgress("Turn cell on, done",
                    EMethodResponse.ON_NM_REQ.FromEnumToString()  );
        }
        else if(disable == false && swtichCellOn == false){
            setMobileDataEnabledMethod.invoke(conman, false);//turn cell off

            DispatcherAndroid.androidObserverItf.androidObserver_OnProgress("Turn cell off, done",
                    EMethodResponse.ON_NM_REQ.FromEnumToString()  );
        }   
        else if((disable == false && swtichCellOn == true) || (disable == true && swtichCellOn == false)){
            DispatcherAndroid.androidObserverItf.androidObserver_OnProgress("No changes",
                    EMethodResponse.ON_NM_REQ.FromEnumToString()  );
        }

    }
    catch(Exception e){
        e.printStackTrace();
    }
}
