Q:如何播放声音时接听电话/如何MOD Android操作系统

I'd like a sound to play every time I answer a call and hang up. I found a similar question with a good answer here

I feel confident with C# and have briefly taken a look at Java so the programming shouldn't be a problem but I haven't gotton involved with flashing custom roms or anything before. Where can I start with getting this to work? Do I use the android sdk or will I have to make a custom flash and if so where do I start with that?

Note: I do not want to create an app that does this I'd like it built right in so I can change which sound plays on answer and hang up (if any) in the settings where everything else is.

我想要一个声音播放每次我接听电话挂断。我在这里找到了一个很好的答案类似的问题

我觉得自信与C #和简要在java编程一个看起来不应该是个问题,但我没有得到参与闪烁的定制ROM或什么的。我从哪里开始得到这个工作?我使用Android SDK或者我要做一个自定义的Flash,如果我从哪里开始呢?

注:我不想创建一个应用程序,这是我想它内置的权利,所以我可以改变声音播放的答案和挂起(如果有的话),在设置的一切都是。
