Before I used eclipse to export the package without eclipse, the following error message did not appear. Recently, I used Android studio to package, build.gradle used dependencies to import the v4 package, and then packaged the following problem. After consulting multiple materials, I found some android-support -v4 is a problem that this method cannot be found, and it can be solved by replacing the normal V4. The younger brother is a little talented and knowledgeable, and I am not very clear about the expression, but I hope it can help everyone and save everyone's time.
