当重新启动我的旧项目时,我正在努力解决奇怪的问题。
我有两个项目:
当我尝试启动应用程序时遇到错误:
java.lang.RuntimeException:
Unable to instantiate activity ComponentInfo{org.bsoftware.catengine.example/org.bsoftware.catengine.example.MainActivity}:
java.lang.ClassNotFoundException:
Didn't find class "org.bsoftware.catengine.example.MainActivity" on path:
DexPathList[[zip file "/data/app/org.bsoftware.catengine.example-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]
之前很少有信息"只需修复清单"评论:)
当它是一个Android应用程序(一个项目)时,一切正常。
当MainActivity从提供的jar文件(它扩展Activity的抽象类)扩展CatEngineActivity类时,应用程序崩溃。
你有什么想法在这种情况下出了什么问题吗?

我也试过了完整的包裹路径:
android:name="org.bsoftware.catengine.example.MainActivity"
可以在此处找到概念证明: https://github.com/mbienkowski/problems/tree/feature/001
答案 0 :(得分:0)
您能否在MainActivity&amp;中提供代码? CatEngineActivity?
我怀疑CatEngineActivity使用xml布局文件作为setContentView()?如果是这样,那么原因是因为android资源没有打包在你的jar文件中。您必须将CatEngineActivity打包为AAR文件,该文件将包含您的Android资源。
如果是这样,请在AAR上试用这个入门套件,看看它是否有帮助。您可以忽略上传到bintray。
