Preface

When we take advantage of apktool.jar There may be various errors when compiling back , Most of them are errors caused by resource files , First, we can update apktool.jar, This is the connection http://ibotpeaches.github.io/Apktool/. The following are the relevant problems I encountered and the solutions ：

1. Yes PNG File parsing failed
