嵌入式菲利克斯，Android的应用程序着决心org.osgi.framework内运行 [英] Embedded Felix, running inside android-app cant resolve org.osgi.framework
问题描述
我无法弄清楚，为什么会发生以下情况：
i cant figure out why the following happens:
我正在从一个小小的Android应用程序的嵌入式的Apache费利克斯。我在开始后的框架编程方式安装2束，但双方从未进入解决状态。从而捆绑MyBundle1进口MyBundle2。
I am running an embedded apache felix from a small android application. I programmatically install 2 bundles after starting the framework, but both never enter the "resolved" state. Thereby the Bundle "MyBundle1" imports "MyBundle2".
这是什么logcat的告诉我：
This is what Logcat tells me:
05-17 20:21:56.514: ERROR/MainActivity(384): org.osgi.framework.BundleException:
Unresolved constraint in bundle de.xy.MyBundle1 [1]: Unable to resolve 1.11: missing
requirement [1.11] package; (package=de.xy.MyBundle2) [caused by: Unable to resolve 2.0:
missing requirement [2.0] package; (&(package=org.osgi.framework)(version>=1.5.0))]
我完全理解错误消息说的话（嗯... org.osgi.framework在1.5+版本不能得到解决），但我无法弄清楚为什么会这样。为什么不能框架决心自己？我试着运行相同的felix.jar与亚行的shell独立的，两者捆绑工作。 Ofcourse，该felix.jar是最新的（3.2）
I totally understand what the error-message says (well...org.osgi.framework in version 1.5+ cant be resolved) but i cant figure out why this happens. Why cant the framework resolve "himself"?! I tried to run the same felix.jar as standalone with the adb shell , and both bundles work. Ofcourse, the felix.jar is up to date (3.2)
谢谢你的建议！

throw new IllegalStateException(ex);

m_felix = new Felix(m_configMap);
try {
m_felix.start();
} catch (BundleException ex) {
Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);
}
我不知道有没有事做与previous问题：
I dont know if it has something to do with the previous problems:
05-18 08:52:59.149: VERBOSE/out(363): Problem creating boot delegation class loader: java.lang.reflect.InvocationTargetException
05-18 08:52:59.209: VERBOSE/out(363): ERROR: Error parsing system bundle export statement: (java.lang.IllegalArgumentException:A header cannot be an empty string.)
05-18 08:52:59.209: VERBOSE/out(363): java.lang.IllegalArgumentException: A header cannot be an empty string.
我安装和
myBundle1= bundleContext.installBundle("file:/data/felix/MyBundle1.jar");
myBundle2= bundleContext.installBundle("file:/data/felix/MyBundle2.jar");
myBundle1.start();
他们被previously dx'ed并移动到/数据/菲利克斯用的亚行推的
同样的code我在Android应用中使用也适用常规的Java控制台应用程序内。
The same code I used in the android-application also works inside a regular java console-app.
推荐答案
在构建框架的方法看起来不错给我。你可以考虑
The way you build up the framework looks okay to me. You could consider
- 替换
FRAMEWORK_SYSTEMPACKAGES由特定于Android，列表，如果你的包将如使用可活动），或 - 不使用临时文件，而是指向了一些你知道存在目录。
- replacing the
FRAMEWORK_SYSTEMPACKAGESby a list that is specific for Android, if your bundles will e.g. be using Activities), or - not using a temp file, but point to some directory you know exists.
我们已经在过去使用3.0.1成功，而我有你张贴的错误信息有什么用它做的想法。你可以尝试该版本的菲利克斯，以及其是否正常工作，你可能已经发现，在菲利克斯回归，然后你就可以到users@felix.apache.org汇报。
We have used 3.0.1 in the past successfully, and I do have the idea that the error message you posted has something to do with it. You could try that version of Felix, and if that works, you may have found a regression in Felix, which you can then report to users@felix.apache.org .
