What is AP_ file?

The file with the extension AP_ is the Developer Files file type. The author of this format is Google. In addition to this file, the Developer Files category includes 1205 related files. ADT Android Developer Package appears on 4 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Android, Linux, Mac OS, Windows. It is recommended to use Eclipse to handle this file. This is a program created by The Eclipse Foundation. There are also 6 alternative programs to handle the AP_ file. 7-Zip, Google Android SDK Tools, Google Android, Google Android SDK will apply when it is not possible to use Eclipse.

How to open AP_ file?

The main problem with ADT Android Developer Package is that the AP_ file is incorrectly associated with programs. This causes the file AP_ to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the AP_ 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 Eclipse

In this case, you should first verify that the Eclipse application is installed on the computer. The easiest method is to use the system search engine by entering the program name Eclipse in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open AP_ files.

Step 2. Create association of Eclipse with AP_ files

If the application is or has been freshly installed, but the AP_ file still does not use the Eclipse program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the AP_ file with the Eclipse program.

Step 3. Update Eclipse to the latest version

If, despite the association of the Eclipse program with the ADT Android Developer Package file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the The Eclipse Foundation website and install the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the AP_ file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file AP_ or the program directory. Sometimes virus-infected AP_ files cannot be recovered, so make a backup in advance.
Older version of AP_ file may not always be supported by the latest software version. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged AP_ files. The easiest way to restore the file is from a backup or by contacting Google, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted file AP_ except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the AP_ file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the AP_ file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
