<!-- TO TRY THIS SAMPLE: change the package name below ("package" attribute of
     the <manifest> tag to your own package name. It must not start with
     com.example, com.google or com.android.

     Also, make sure to correct the references to the R object. You can do that
     by adding "import your.package.name.R" to each source file that references
     the R object (where, naturally, "your.package.name" stands for your actual
     package name).

日志基本上说它找不到你的活动“JrhMainActivity”。你确认它确实存在吗？此外，根据您的包结构，您可能需要更改清单中的“名称”字段以获得完全限定的路径。
