What is DEX file?

The DEX file has been categorized as Developer Files. The author of this format is Google. Additionally, the Developer Files category contains 1205 of other files. Dalvik Executable Format is most often found on 4 operating systems. The file will work on Android, Linux, Mac OS, Windows systems, unfortunately not on others. The Google Android SDK application is recommended to open the file. It was released by Google Inc.. This file type can also be opened by 7 other programs. The Eclipse, IntelliJ IDEA, Dex2Jar, Dedexer programs will also handle the file when the Google Android SDK program does not fulfill its role.

How to open DEX file?

An often recurring problem with Dalvik Executable Format is that DEX is not associated with the correct program file. This causes the file DEX to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the DEX file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Google Android SDK

In this case, you should first verify that the Google Android SDK application is installed on the computer. To do this, enter the name Google Android SDK into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file DEX with Google Android SDK. Later in this article you will find a list of programs that can open DEX files.

Programs to open DEX file

Remember to download programs supporting DEX files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Google Android SDK with DEX files

However, it may happen that the application itself does not cause the DEX file to open in the Google Android SDK application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the DEX file with the Google Android SDK application.

Step 3. Update Google Android SDK to the latest version

If, however, after binding Google Android SDK with Dalvik Executable Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Google Inc. website and install the latest version.

Step 4. Check for the following problems with the DEX file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the DEX file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the DEX file that we want to open. As a result of the scan, sometimes it is not possible to recover DEX files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the DEX files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged DEX files. The easiest way is to restore the file from a backup, if there is one, or contact Google
When reading, a message appears that the file was encrypted or corrupted. The encrypted DEX files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move DEX to a different directory.
This problem usually affects more complex files. In this case, the DEX file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the DEX file again. However, some background programs may block the DEX file while scanning. If this does not work either, restart the device.
