More from the Internet download the support library, put Android-support-v7-appcompat.jar into the Libs directory, and added to the compilation path, this thought all right, but reported the following a mistake, how?
The type android.support.v4.app.taskstackbuilder$supportparentable cannot be resolved. It's indirectly referenced from required. class files are confirmed because of our original Android.support.v4.jar This package version and our Android-support-v7-appcompat.jar package is not compatible, on the Android development site clearly stated that the V7 package is dependent on the V4 package, then that is to say, it will certainly have a version of the problem Inside, and again, in the support package we downloaded, Also provide us with a Android-support-v4.jar package, so it is clear to tell us, do not use your project in the original Android-support-v4.jar package, with our give you this package, decisive change, OK, wrong solved, haha, start it ...
