How To Use Bytecode Viewer
Run BVC, and then add a jar, class or APK file into the workspace.
Then, select the file you’d like to view from the workspace.
BCV will automatically start decompiling the class in the background. When it’s done it will show the Source code, Bytecode and Hexcode of the class file you chose (depending on the View panes you have selected). If you are trying to view a resource BCV will attempt to display it the best it can with code highlighting or by embedding the resources itself.
