Unfortunately, as if the developers of mobile"Operation" did not try to improve them, new versions in the pursuit of the rating look rather raw. In particular, when switching to Android 5.0, many owners faced a fairly serious problem when the system itself when installing an application from the same Play Market gives a message with the code 505 "Error" (and unknown). What to do in this case?
Code 505: Android 5.0 operating system error?
Naturally, all owners of mobile equipment withoperating system Android version 5.0 on board immediately seek to write off all the shortcomings for the very "OSes", they say, it was not completely finalized. But is it?
Indeed, there are some problems with the system.But they most often concern the workability of already installed applications and their updates. As for newly installed software products, there are no problems here.
In what cases does unknown error 505 occur?
The situation with the appearance of such failures, of course,nobody will be happy. Let's try to figure out the case when exactly and why error 505 occurs. What does this mean? It's just that the system does not recognize the so-called "self-signed" applications during installation. In other words, it does not trust not that the source, but the developer's signature itself, believing that it is either potentially dangerous or undesirable, or because it does not work in this environment (although it is not) .
And the saddest thing is that not alldevelopers of software for Android-systems are monitoring the creation of updates of their own software products in connection with the release of new versions of the OS. In particular, this concerns developments such as "GPS Antiradar" or HUD Speed.
In addition, for some reason, the greatest number of failuresthis kind is observed on the Nexus 7 tablets. But one can not complain about the "operating system", because the devices themselves, according to the creators, are imperfect and often simply "hang" for no apparent reason.
The simplest methods of correction
So, let's take into account the situation that the failure did happen, and the message on the gadget screen appeared with code 505. The error is eliminated quite simply.
To begin with, if an old application is notIt works, you just need to completely remove it. Note that the standard scheme for deleting a program by dragging an icon to the "Trash" does not always help. After that, you need to clean up the system with utilities like CCleaner for the presence of residual records. But that's not all. The fact is that some applications create hidden cache folders that, when uninstalled, are not deleted at all (for example, a VKontakte client or FL Studio Mobile music sequencer).
In the case of a re-installation, a reference is made to theExisting files that the installer itself defines as outdated versions that cause conflict. In this case, unlike the same versions of Windows OS, the Android system does not give permission to replace them. So it turns out that the application seems to be updated, and the cache is old.
But back to the time when error 505 occurs. How can I fix it in the simplest way?
To start, you need to turn on USB debugging modein the gadget settings. In the information about the device, you need to get the developer's rights, "tapping" 7 times on the line of the version of the system build (if there is root-right of the superuser, and even better).
Now we connect the device to the computer throughUSB, after installing the Android Debug Bridge utility. Now run the file Run.bat, which is located in the ADB folder (no matter where it is on the hard drive of the computer), then the screen should show the successful execution of the commands contained in it. This will be a confirmation message: Success. Now you can start and install new applications without any problems.
In some cases, the problem may also be related todevelopers, or rather, development tools. Then, too, a message with code 505 appears. The error in this case is eliminated by creating the installation APK-file not by the 15th version of Adobe Air, but by the 14th. In most cases, this fixes all problems with the subsequent installation of applications from Google Play (Play Market).
Conclusion
As you can see, a problematic unknown error, likethe system reports, in general it is recognized without any problems and is eliminated quite simply. In this case, the main factor is the use of specialized software and the inclusion of developer mode.
As for the creators of applications forAndroid 5.0, Adobe Air development environment of the 15th version is also imperfect and that's why it can cause conflicts. As already clear, and there is a solution to the problem.
