Powered by several open source tools BCV is designed to aid in the reversing process.\n\nBCV comes with 6 decompilers, 3 disassemblers, 2 assemblers, 2 APK converters, advanced searching, debugging & more.\n\nIt's written completely in Java, and it's open sourced. It's currently being maintained and developed by Konloch.\n\n## Is there a demo?\n[![BCV Demo](https:\u002F\u002Fimg.youtube.com\u002Fvi\u002FI5GT6PoTGOw\u002F0.jpg)](https:\u002F\u002Fwww.youtube.com\u002Fwatch?v=I5GT6PoTGOw)\n\nPlease note this demo is from a very old version\n\n## How do I install BCV?\nDownload the latest version from https:\u002F\u002Fgithub.com\u002Fkonloch\u002Fbytecode-viewer\u002Freleases and run the Bytecode-Viewer-2.10.x.jar.\nYou may need to execute it via command line ```java -jar Bytecode-Viewer-2.10.x.jar``` (replace the X with the current minor version)\n\n## How can I use BCV?\n* Starting with a Jar, Zip, ClassFile or Android file (APK, DEX, XAPK, APKM, etc) drag it into BCV. It will start the decoding process automatically.\n* From here you can select the decompilers you would like to use by selecting the View Pane>View 1, View 2, View 3, etc.\n* The view panes are-used to display up to 3 decompilers side by side, you can also toggle edibility here.\n* Select the resource you would like to open by navigating using the resource list, BCV will do its best to display it (Decompiling, Disassembling, etc).\n* You can use plugins to help you search along with using the search pane in the left-hand bottom corner.\n\n## How do the plugins work?\nThere is also a plugin system that will allow you to interact with the loaded classfiles. You could for example write a String deobfuscator, a malicious code searcher, or anything else you can think of.\n\nYou can either use one of the pre-written plugins, or write your own. The plugin system supports java and javascript scripting.\n\nOnce a plugin is activated, it will execute the plugin with a ClassNode ArrayList of every single class loaded in BCV, this allows the user to handle it completely using ASM.\n\n## Instructions to compile\n\nJust clone this repo and run ``mvn package``. It's that simple!\n\n## Working on the source\n\nOpen the Maven project (e.g. in IntelliJ, open the ``pom.xml`` as a project file).\n\n## UI Is Lagging\nChange the theme to your systems. Go into `View->Visual Settings->Window Theme` and select `System Theme`.\n\n## Java Heap Space Issues (java.lang.OutOfMemoryError)\nStart BCV with more RAM, e.g. `java -Xmx3G -jar BCV.jar`\n\n## File Permission Issues (java.io.FileNotFoundException)\nRight click on the jar file, go to Properties, and select Unblock under Security at the bottom of the General tab.\n\n## APK File Permission Issues (java.io.FileNotFoundException)\nRun BCV as administrator.\n\n#### Are you a Java Reverse Engineer?
