Today, when I wrote the program, my Android Studio suddenly compiled the error (the error is as follows:) and then after my several times to find out that every time you have to clear project and then build on it, if you build the second time to error. Then I found the strongest teacher (Google) to try to solve! Unfortunately, what I see on Google is the solution on eclipse. Didn't find the answer I wanted, do I have to clear project every time I buil

Analysis of Dex splitting (MultiDex) technology in AndroidI. Preface The subcontracting Technology in Android is no longer a new technology, and there is a lot of analysis on the Internet, but they all give theoretical knowledge and Principle Analysis, and there is no detailed case description, so here we will explain in detail the analysis of the dex splitting t

Recently, an open-source Library Project Android-viewpagerindicator was used in the development of a project. This project appears as a library, for example: This project contains the android-support-v4.jar The library is referenced in another project, for example: Then compile the project, and the error described in the title is repeated. Since the project itself does not have the

The number of Dex file methods in your app exceeds the maximum limit of 65536, so simply put, the app is bursting.So let's see why this error is caused:In the Android system. All the code for an App is inside a Dex file.

Android uses android-support-multidex to solve the problem of Dex exceeding the limit of the number of methods, so that your application will not burst into the dark. androidmultidex If you have reprinted, please declare the Source: sand: http://blog.csdn.net/t12x3456 (from the sand csdn blog) With the continuous iteration of applications and the expansion of bus

Android uses android-support-multidex to solve the problem of Dex exceeding the limit on the number of methods, so that your applications will not burst With the continuous iteration of applications and the expansion of business lines, applications become larger and larger (such as integrating various third-party sdks or jar packages supported by the public, wit

automating identification is increased if the code is confused with the technology. Dynamic analysis is easier to deal with this "hidden" approach.2. Code logic "hiding" in the resource fileYou can hide the code logic by modifying the file suffix name, such as:File suffix shadowing allows you to see whether a file type is easily identifiable with a suffix by using the files command.We can also do a bit more advanced. The elf executable binary is appended to a valid picture file, and the correct

Simply put, the idea is to package the compiled class file into two Dex, bypassing the limit on the number of Dex methods and checking the installation, and then dynamically loading the second

Thoughts on Multiple dex files define compilation errors in Android Yesterday, my long brother asked me a question. He said that if a project contains com. x. A enumeration. The imported third-party jar also has A com. x. A enumeration, which enumeration will be used when I use A enumeration in the project? I thought, isn't this a class (enumeration is a special class) Definition conflict? It should be repo
