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.

Posted by Tim Bray on 28 July 2011 at 8:35 AM [This post is by Fred Chung, who's an android developer advocate-Tim Bray] 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 every application; in fact, most do just fine

In this compilation process will also produce a r.java files so

In an Android system, all the code for an app is inside a dex file. Dex is a jar-like archive that stores many Java-compiled bytecode. Because the Android system uses the Dalvik virtual machine, you need to convert the class file that was compiled with Java compiler into a class file that Dalvik can execute. The point here is that Dex, like the jar, is an archive

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 reported during compilation, and I have encounter

When our project code is too large, the compile run will report unable to execute Dex:method ID not in[0, 0xFFFF]: 65536) error. When this error occurs, you have too many methods in your own engineering code, or the third-party plug-in jar package referenced under your project Lib folder has too many methods, both of which add up to more than 65536 of this number. Google requires that the method in a single Dex file not exceed the 65536 limit.So this

The reasons for the need for Dex must be known to all. It was in the previous Android system that the Dex file was stored with a short type of data for the method index. The maximum value for short is 65535, so when the project is large enough to contain more than 65535 of the methods (including all the methods in the referenced external Lib), when you run the app, you get the following error message.inch [
