Owners of mobile gadgets running OS Android often encounter an unpleasant situation when trying to install some applications, when instead of a successful installation, a syntax error appears on the device’s screen when installing the APK. Now we will consider the causes of its occurrence and the simplest methods of correction.
Syntax error installing apk file: reasons
First of all, you need to pay attention to the most basic things. So, for example, the option is not ruled out that the installation file itself is either under-downloaded or simply damaged. Most often this applies to situations when the file was not taken from the Google Play (Play Market) service, but downloaded from the Internet.
However, the most common phenomena can be called, say, the moment that the APK installation file is not designed for the version of Android OS currently used on the device, as well as the fact that the system settings simply block the installation of third-party files received not from an official source (in in our case, this is the Play Market service).
If you consider the default settings, it is easy to guess that the "OS", in fact, prohibits the installation of user applications. So it turns out that installing APK-files on Android becomes impossible due to current restrictions on the part of the system. However, there is always a way out, as they say.
Syntax error: how to fix (Android)?
In some cases, the appearance of an installation error with the lock of the corresponding file may be accompanied by a notification about the lack of free space. Do not be upset. Everything is in order with the gadget. It's just that the syntax error itself when installing the APK-file manifests itself in this way.
To fix access to the installation, you need to perform simple steps. It all comes down to disabling bans. In the simplest version, you need to use the settings menu, where the security settings are selected. There is a special field “Unknown sources”. Its activation (checkmark opposite) also involves the installation of permissions for installing applications from third-party distributions.
If the syntax error when installing the APK distribution appears again (most often it is associated with the parsing of the installed application), you should pay attention to the state of the package itself. You can try downloading it again and reinstalling it.
Along the way, you need to look at which version of the system this program is designed for. For example, the application is designed for use in the Android 5.1 Lollipop environment, and the user is trying to install it in the 4.2 Jelly Bean or 4.4 KitKat environment. It is clear that the OS itself simply will not accept it (it does not recognize that it will work in this environment). Here you can give an analogy with Windows. Not a single application, say, for Windows 7 or 8 in Windows XP, will not even launch, but will not even install (this is to make it clear). The same is with Android modifications.
In this case, you will need to find the installation file, designed specifically for that version of the system that is used on the gadget. By the way, sometimes this situation may also occur in the case of the independent installation of certain types of firmware. There is no guarantee that the installation will be successful.
Total
However, as you can see, the situation with errors is corrected quite simply. True, in most cases, this applies to Android devices that are not flashed. Otherwise, the most basic settings allow you to avoid errors in the future.
