App常用状态获取

1.获取系统设置里面的响亮和振动是否使能

Settings.System.getInt(Context mContext, "vibrate_when_ringing",0);

2.获取系统当前网络制式

int netWorkMode;
                try {
                    netWorkMode = Settings.Secure.getInt(MainActivity.this.getContentResolver(), "preferred_network_mode");
                    System.err.println(netWorkMode);
                } catch (SettingNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

3.获取移动数据开关状态

public static boolean getMobileDataStatus(Context context)  
    {  
        String methodName = "getMobileDataEnabled";  
        ConnectivityManager mConnectivityManager = (ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        Class cmClass = mConnectivityManager.getClass();  
        Boolean isOpen = null;  
          
        try   
        {  
            Method method = cmClass.getMethod(methodName, null);  
  
            isOpen = (Boolean) method.invoke(mConnectivityManager, null);  
        }   
        catch (Exception e)   
        {  
            e.printStackTrace();  
        }  
        return isOpen;  
    }
