A simple shell removal instance (dex) and shell removal dex
I just finished my work and just analyzed a reinforced game. I remembered that I didn't send an analysis process in the last post and recorded a video,Here is a simple addition.For the new version of this shell, there are also tutorials on the Internet, the dex has been removed successfully,
Problem Overview: The program is compiled normally. When you use eclipse for debugging and execution, the following error occurs: unable to execute DEX: Multiple Dex files define. Because this type of error has not been encountered before, you should first try to make a universal error, the following method 1 is also one of the solutions for online search. If the solution fails after the attempt, the system
Method 1: eclipse-> Project-> remove build automatically-> clear-> build project-> build automatically, disable eclipse, and enable Method 2: update the ADT plug-in, delete. metadata directory method 3: A folder under your project has a suffix *. delete the APK file and restart eclipse. Method 4: The cause is repeated. Jar is referenced. You can view your build path. In particular, Android dependencies must have repeatedly introduced. Jar packages. Th

When eclipse is used for debugging and execution, the following error occurs: unable to execute DEX: Multiple Dex files define.The specific solution is as follows:In the project, the package name of a class is the same as the class in the referenced jar package.

This is a compilation error. When the ADT compiler differs from the SDK tool or the version is inconsistent, a problem often occurs. The solution is as follows:
Step 1: Updated eclipse (Help-> check for updates)
Part 2: Upgrade the SDK tools and platform-Tools
Part 2: Go to eclipse-> Project-> remove automatic build (build auto
Solution: this problem may occur during the packaging process because repeated jar files are referenced. You can view your build path, in particular, Android dependencies must be introduced repeatedly. jar package. The solution is to delete duplicate jar files in libs.
If not, you can delete the referenced jar and re-import it. During the import, you can directly find the jar from the project source file directory.

The Dalvik VM provides facilities for developers to perform custom class loading. instead of loading Dalvik executable ("Dex") files from the default location, an application can load them from alternative locations such as internal storage or over the network.
This technique is not for
Dalvik command analysis (3) dex file structure, dalvikdex
Take the dex file generated in the previous article as an example to explain the dex file structure. The dex file structure is very simple, and there is only one HelloWorld. java
For the basic format of the dex file,
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 fil

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 i
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
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

3. Art replaces Dalvik
In KitKat, the art mode can be switched in "Developer options", but this option is not added to Sony 4.4. The reason is that the application needs to be optimized; otherwiseCompatibilityPoor risk, and optimization will delay the release time of the new system.
The art mode is faster than Dalvik, but it also has some disadvantages:
1. It will increase the storage space occupied by the Program (not a lot ).
2. More power consumptio
If you are an Android developer, you have at least heard of Dalvik's 64K method limit for egg aches. In a nutshell, you can call a lot of methods in a Dex file, but you only have to call the first 65,536 of them, because this is all the space in the method call collection. If your source code and the crazy drag-and-drop method in the three-way vault of the day exceeds this limit. Look at this article.UNEXPE
Dex introduces mongodb index and query analyzer dex. It is a MongoDB performance adjustment tool that compares MongoDB log files and index entries and provides index recommendations. Currently, you must provide a URI to connect to the database. Dex only recommends full indexes, not partial indexes. Windows platforms are not supported.
In today's mobile security environment, the program Packers have become commonplace, if not shelling can not be able to crack the rhythm of the world. Zjdroid as a universal shell is very useful, but when the author publicly released the project has been a variety of Packers, such as the preemption of Zjdroid broadcast receiver so that zjdroid can not receive commands.
