) Yes, the number of Dex file methods in your app exceeds the maximum of 65536, so simply put, the app is bursting. in the Android system, all the code for a App is in a Dex file. Dex is a jar-like archive that stores multiple Java compiled bytecode. Because the Android system uses the Dalvik virtual machine, you need to use Java Compiler

in the previous period of time doing Android projects, there has been a problem of more than 65535 methods, if the number of methods in the code is not more than 65535, you canadd a line to the Project.Properties file dex.force.jumbo=true, solve this problem. Later, referring to some methods on the Internet, I wrote a gadget to count the number of methods in jar packages and Dex files. The main principle is to use the

tool. This is what we can see in our Android project's packaged APK: the introduction of the contents of the other jars is packaged into the classes.dex.So this road is not through, please pay attention.1.2 What APIs are currently available for dynamic loading1.2.1 DexclassloaderThis can be loaded Jar/apk/dex, can also be loaded from the SD card, is also the focus of this article.1.2.3 PathclassloaderYou can only load apk files that are already insta

One, Dex and Odex Dex is an executable file for the Android Dalvik virtual machine that can be opened directly in the exported APK file using the Unzip software. Odex is optimized for Dex. Odex one is extracted from the APK program, and the APK file in the same directory, the file suffix is odex, such odex files are mostly Android ROM system program, and

Use the android packaging tool (aapt) to combine Dex files, resource files, and androidmanifest. xml files (in binary format) into an application package (APK ). When optimizing the android Dex file, you must note that the DEX file structure is compact, but we still need to find ways to improve the running speed of the program, we still need to further optimiz

Class file to generate the dex file operation steps, classdex 1. A dx. bat is required to generate dex. The specific directory is Android \ sdk \ build-tools \ 21.0.1 (not specified in 21.0.1, which is available in each tool) 2. Configure the environment variable. The path is the directory under dx. bat. 3. Open command line cmd Dx -- dex -- output = C: \

When optimizing the Android DEX file, you must note that the DEX file structure is compact, but we still need to find ways to improve the running speed of the program, we still need to further optimize the DEX file. Adjust the byte order of all fields LITTLE_ENDIAN) and none of the fields in the alignment structure verify that all classes in the

Well, I've thought about not moving Android in the future, but I didn't think it was the reason for the game. Many of the problems with Android are due to the imperfections of eclipse, such as the problem encountered today unable to execute Dex:multiple Dex files define[ .-Ten- at -: at: in - Dex Loader] unableTo execute Dex: multipledex Files Definelcom/MyApp/R

Hello everyone, here we will introduce the APK decompilation operation:1: APK Decompilation2: Convert odex to Dex Operating Environment: Ubuntu A: decompilation APK To code.

Dexclassloader loads a class that has no component life cycle, meaning that even if dexclassloader loads the component through dynamic loading of Dex, the load class fails when the system starts the component.There are two ways to solve the problems that appear above:Method One: http://blog.csdn.net/androidsecurity/article/details/8809542, change the classloader of the system to make it a custom loader.Features: Two

Dex is a file format that can be directly run on the Dalvik virtual machine in the Android system. Java source code is converted into Dex files after complex compilation by ADT, which is a step-by-step optimization process. The Dex File Script is a set of instruction sets proprietary to the Dalvik virtual machine. It is specially optimized for embedded systems. C

The Dex file is a Java binary file running on delvik on Android. If you are interested in the content and the developer has not published the source code, you can decompile the DEX file using the following method: 1. Decompress system. img Use xyaffs2 to decompress system. IMG and the imgfile you want to decompress: Xyaffs2 img_file output_dir Xyaffs2 can be downloaded from the following address: Http://lim

In Art, DexClassLoader converts dex to the oat file format. dexclassloaderoat After reading the source code DexClassLoader, the native function openDexFileNative in the DexFile class will be called. Next let's take a look at what the openDexFileNative function has done. The openDexFileNative function exports the openDexFileNative symbol in the code in the art \ runtime \ native \ dalvik_system_DexFile.cc file. static JNINativeMethod gMethods[] = {

filesystem, but to load the android executable with Dexclassloader Dex You must first store it on the file system, which is the biggest difficulty in adding shells to the Dex file. In order to solve this problem, I think of two ways, the first method is to reduce the time exposure in the file system,Dexclassloaderafter the source program is loaded, it is removed from the file system immediately, so that

I just finished my work and just analyzed a reinforced game. I remembered that the analysis process was not found in the last post, and I recorded a video. Here I will simply add it.For the new version of this shell, there are also tutorials on the Internet, the DEX has been removed successfully, and you will have time to make another video later.Previous: Android learning ManualHttp://www.52pojie.cn/thread-280588-1-1.htmlThe operation in this article

Java also has the class loader ClassLoader, which is the role of dynamic loading class files, when we download class files from the network, or do not participate in the compilation at the time of the runtime to call when the class loader. Because Android has repackaged and optimized the class file, the final apk file contains the Dex file, which is required to load the file with Dexclassloader.Dexclassloader (Dexpath, Optimizeddirectory, LibraryPath,

DVMAnyone familiar with Android knows that android applications can be developed in Java. However, the Android operating system only uses the Java language. The virtual machine that actually runs Java code is not a JVM, but a DVM (Dalvik virtual machine ). DVM does not comply with JVM specifications, mainly in the following aspects: The JVM is stack based, and the DVM is register based. JVM executes Java bytecode, and DVM has its own bytecode. JVM requires that Java code be compiled
