After many years of searching, you finally found a dungeon of slugs, of which only legends went. You have heard the story that there are untold treasures there. And now you are standing at the entrance. But when you got inside, you realized that getting to gold would not be so easy. The road to you is blocked by slugs. So you have to use your mind, skills and ability to think through the moves to get inside.
After the download is complete, the downloaded file will be displayed in the notification shade (top), and will also be located in the "Download" folder (any file manager )
Install the downloaded APK file using any file manager or by clicking on it (on the downloaded file) in the notification shade
If you are installing apps for the first time not from Google Play (but using a file manager or browser), you will need to grant the appropriate permission. This is done only once.
If the file was downloaded with the bin extension, then there are 2 options:
Change the extension of the downloaded file to apk using any file manager ("rename" function)
To update the application, install the new version of the application over (without deleting) the old one.
This update will only be possible if the previous version of the application is downloaded from us. Otherwise, there will be a signature conflict and you will see the message "Application not installed".
For what "Signatures" are and what they are for, read here.
