问题描述
我在Android上，我想与下载的附加组件扩展迷你钢琴应用程序。我想例如具有grandpiano作为一个单独的安装包的音色。
I have a mini piano app on android that I would like to extend with downloadable add-ons.I would for example have the soundset of a grandpiano as a seperate installable package.
我看到一些应用程序有插件（如NIV圣经，即添加不同的圣经版本）。我想知道我可以集成一个单独的APK附加到我的主程序。我怎样才能访问这些？什么我需要做整合这些加载项？等等。
I see some apps that have add-ons (like the NIV Bible, that add different bible editions).I would like to know how I could integrate a seperate apk add-on into my main program. How can I access those? What would I need to do to integrate these add-ons? Etc.
任何指针？
例子
本NIV圣经有几个附加组件在市场上，你可以利用市场下载。它看起来像这些真正使用包含在其包中的数据。
The NIV bible has several add-ons in the market that you can download using the market. It looks like these really use the data contained in their packages.
另外，我知道Ruboto使用ruboto芯封装，包含JRuby的东西，那被安装一次，所有Ruboto软件包依赖于那一个，所以它必须能够
Also, I know that Ruboto uses a ruboto-core package, that contains the JRuby stuff, that gets installed once, and all Ruboto packages rely on that one, so it must be possible
推荐答案
我发现它可以访问其他APK的资源。我不知道它是否仅限于具有相同签名的应用程序，这不是我试过。我不知道，你可以访问其他的apk code，因为这是笏ruboto是干嘛用它的ruboto-core包。
I found out that it's possible to access other APK's resources. I don't know if it's limited to apps that have the same signature, that's not something I tried. I do know that you can access other apk's code, since that is wat ruboto is doing with it's ruboto-core package.
从另一个安装APK访问资源：
To access resources from another installed APK:
//Get the other apk's resources
Resources resources = context.getPackageManager().getResourcesForApplication(
"package.name.goes.here");
//Then you need to get the ResID
int resID = resources.getIdentifier(
"name_goes_here", "string(or other type like raw)", packageName);
//Open stringResource
String resourceString = resources.getString(resID);
这也与原材料资源工作！
This also work with raw resources!
