禁用/启用Android上大号的移动数据有根存取权限 [英] Disable/Enable mobile data on Android L with root acces

问题描述

我写一个小程序，只有我会用，我要以务实的态度启用/禁用我的移动数据有根的Andr​​oid 4.5设备上（我运行一个定制的Andr​​oid L代表的Nexus 4）。

I am writing a little app that only I will use and I want to pragmatically enable / disable my mobile data on a rooted android 4.5 device (I am running a custom Android L for Nexus 4).

我已经看过了一段时间，我发现反映，一直工作到安卓4.3的方法。 我也看到了方法，从这个帖子<一个href="http://stackoverflow.com/questions/21511216/enable-and-disable-mobile-data-programmatically-on-android-4-4-2">Enable和禁用移动数据编程在Android 4.4.2 但这需要CyanogenMod的。

I have looked for a while and I found the methods with reflection that worked until android 4.3. I have also seen the method from this post Enable and Disable mobile data programmatically on android 4.4.2 but this requires cyanogenmod.

这是我能找到上网本上是对于非root用户的​​应用程序是不可能的，但我的问题是：

From what I can find on the internet this is impossible for non-root apps but my question is:

是有什么我可以做的我的root权限做到这一点？的

is there something I can do with my root privileges to accomplish this ?

推荐答案

我创造了这个方法环顾在互联网上;它工作正常的根的Andr​​oid 5.0.1 基本上你，如果你想连接启用，否则为false传递真实的，和你的应用程序的上下文。

I've created this method looking around on internet; it works fine on rooted android 5.0.1 Basically you have to pass true if you want the connection to be enabled, false otherwise, and the context of your application.

private final static String COMMAND_L_ON = "svc data enable\n ";
private final static String COMMAND_L_OFF = "svc data disable\n ";
private final static String COMMAND_SU = "su";

public static void setConnection(boolean enable,Context context){

    String command;
    if(enable)
        command = COMMAND_L_ON;
    else
        command = COMMAND_L_OFF;        

    try{
        Process su = Runtime.getRuntime().exec(COMMAND_SU);
        DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

        outputStream.writeBytes(command);
        outputStream.flush();

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        outputStream.close();
    }catch(IOException e){
        e.printStackTrace();
    }
}

请报告，如果这有一些设备上的问题。

Please report if this has problems on some device.
