Android transfers images or other files in the memory card to another path. This is a simple problem, but it is also a problem we often encounter, that is, how to store images or other files on the memory card during Android development, then we can process this file. Because we cannot process the original file, we are

This is a relatively simple problem, but also we often back to the problem, that is, in the development process of Android, how to transfer memory card pictures or other files, and then processing this file, because we can not process the original file, is currently doing a picture of the Android project, So use this knowledge, and share it with you.private void

Some third-party libraries are developed based on J2SE, which have resource files, such as properties, that are filtered out when Dex is compiled, causing the class to be inaccessible when it reads resources.The workaround is to load the third-party class library with the runtime.1, the third-party class library with DX packaging2. Compress the packaged Dex files

This paper illustrates the method of compressing and decompressing the zip file with Android. Share to everyone for your reference. Specifically as follows: Dirtraversal.java is as follows: Package com.once; Import Java.io.File; Import java.util.ArrayList; Import java.util.LinkedList; /** * Folder Traversal * @author Once * * */public class Dirtraversal {//no recursion public static linkedlist The Ziputils.java is as follows: Package

interface, which is easy to operate. You can decompile a single file or decompile it in batches. DJ: Http://members.fortunecity.com/neshkov/dj.html During batch decompilation, note that the suffix of the output file is changed to Java, and the default Suffix of the output file is Jad. 6 decompile the XML file with axmlprinter: java -jar AXMLPrinter2.jar AndroidManifest.xml AndroidManifest2.xml The axmlprinter is as follows: Http://android4me.googlecode.com/
