1. View the versionCode of android
Generally read from androidmanifest.xml, use the tools AXMLPrinter.jar and AXMLPrinter2.jar online, the author of the maven warehouse is the same person
AXMLPrinter2.jar apk analyzes the APK file and obtains the package name, version number and icon in the APK file. It is a very powerful tool, and once again I feel the power of batch processing. It can decompile the binary XML file (binary xml file) compiled by android and output and save it in plain text. It is one of the necessary tools for APK decompilation and modification. For example, if you need to check the permission and name of the apk installation package, you can use AXMLPrinter2 to decompile androidmanifest.xml to view it in plain text. The decompilation speed is very fast and easy to use, and the .XML file can be compiled smoothly.
CMD execution command: java -jar AXMLPrinter.jar AndroidManifest.xml
