我读了很多关于这个错误的post，但我在代码中找不到错误。 我扩展了FragmentActivity，导入v4.app。
引起：java.lang.ClassNotFoundException：在路径上找不到类“com.example.fragmentexample.ToolbarFragment”：DexPathList [[zip file“/data/app/com.example.myfragmentexample-1.apk”],nativeLibraryDirectories = [/ data / app-lib / com.example.myfragmentexample-1，/ system / lib]]
这个
android:name="com.example.fragmentexample.ToolbarFragment"
一定是
android:name="com.example.myfragmentexample.ToolbarFragment"
导致ToolbarFragment.java包名称是
package com.example.myfragmentexample;
类似于TextFragment
android:name="com.example.myfragmentexample.TextFragment"
尝试在正确的位置添加正确的布局，如前。 在我的情况下，我把colors.xml放在值-w820p然后它给classtype的运行时exception我将文件夹从这个更改为简单值和taddda它工作:)
我也是Android新手，今天遇到了同样的错误。 我找不到适合我的解决方案，但有一件事我很清楚，当android无法解析布局xml中某个元素的强制属性时会出现此问题。
所以我彻底检查了我的布局，发现我错误地创建了一个ID
在ids.xml中。 此ID与属性冲突
android:imeActionId="@+id/login"
EditText元素。
希望这有助于某人。
