The phrase identifies the act of acquiring a specific application package file used for installing the Duboku TV application on Android devices. This process typically involves obtaining the file from a source other than official app stores like Google Play. As an example, a user might perform a web search using those terms to find a website hosting the file for direct installation.
The perceived importance of this method often stems from reasons such as accessing the application on devices where the official app store is unavailable, obtaining older versions of the application, or circumventing regional restrictions. However, it is important to consider potential risks associated with downloading files from unofficial sources, including the possibility of malware infection and security vulnerabilities. Previously, this approach was more common due to limitations in official distribution channels, but the proliferation of app stores has generally reduced the need for it.
