SystemProperties.set不工作 [英] SystemProperties.set not working

问题描述

我在我的资料来源$ C ​​$ C设置SystemProperties以下code。

  SystemProperties.set（ro.csc.countryiso_ code，KoreaA）;        字符串= COUNTRY1 SystemProperties.get（ro.csc.countryiso_ code）;        Log.e（DEBUGA，国家1）;
        SystemProperties.set（ro.csc.countryiso_ code，KoreaB）;
        字符串COUNTRY2 = SystemProperties.get（ro.csc.countryiso_ code）;        Log.e（DebugB，COUNTRY2）;
 

`

为什么我没有得到第二个变化来SystemProperties？
但是在LogCat中调试我总是得到： -
- DEBUGA KoreaA
- DebugB KoreaA
难道只有一次，我们可以从我们的code设置SystemProperties，直到设备关闭并重新打开，将持续到永远？

由于我检查关闭我的设备，并在重新开机后更改： -

我在我的资料来源$ C ​​$ C设置SystemProperties以下code。

  SystemProperties.set（ro.csc.countryiso_ code，KoreaB）;        字符串= COUNTRY1 SystemProperties.get（ro.csc.countryiso_ code）;        Log.e（DEBUGA，国家1）;
        SystemProperties.set（ro.csc.countryiso_ code，KoreaA）;
        字符串COUNTRY2 = SystemProperties.get（ro.csc.countryiso_ code）;        Log.e（DebugB，COUNTRY2）;
 

而在LogCat中调试我总是得到： -
- DEBUGA KoreaB
- DebugB KoreaB

解决方案

  SystemProperties.set（ro.csc.countryiso_ code，KoreaA）;
 

属性的名称以RO开头，表示这是一个只读属性，所以一旦设置，就无法再更改。

I have following code in my Source code to set SystemProperties.

        SystemProperties.set("ro.csc.countryiso_code","KoreaA");

        String country1 = SystemProperties.get("ro.csc.countryiso_code");

        Log.e("DebugA",country1);
        SystemProperties.set("ro.csc.countryiso_code","KoreaB");
        String country2 = SystemProperties.get("ro.csc.countryiso_code");

        Log.e("DebugB",country2);

Why am i not getting Second Change to SystemProperties? But in LogCat Debug I am always getting :- :- DebugA KoreaA :- DebugB KoreaA Is it only the once we can set SystemProperties from our Code and that will persist for ever until device is switched off and turned on again?

As i checked changing after switching off my device and turning it on again :-

I have following code in my Source code to set SystemProperties.

        SystemProperties.set("ro.csc.countryiso_code","KoreaB");

        String country1 = SystemProperties.get("ro.csc.countryiso_code");

        Log.e("DebugA",country1);
        SystemProperties.set("ro.csc.countryiso_code","KoreaA");
        String country2 = SystemProperties.get("ro.csc.countryiso_code");

        Log.e("DebugB",country2);

And in LogCat Debug I am always getting :- :- DebugA KoreaB :- DebugB KoreaB

解决方案

     SystemProperties.set("ro.csc.countryiso_code","KoreaA");

The name of the property starts with "ro", means it's a read-only property, so once set, you can't change it any more.
