</manifest>

我读了很多有关此错误的文章，但在我的代码中找不到任何错误。我延长了android.support.v4.app.FragmentActivity。


问题答案：

原因：java.lang.ClassNotFoundException：在路径：DexPathList [[zip file“
/data/app/com.example.myfragmentexample-1.apk”],nativeLibraryDirectories上找不到类“
com.example.fragmentexample.ToolbarFragment” = [/ 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"

的软件包名称ToolbarFragment.java是

package com.example.myfragmentexample;

同样的 TextFragment

android:name="com.example.myfragmentexample.TextFragment"
