Address Obtaining Method for Download Page Fallback

The patent divides the download page address into multiple segments (first address and second address) with different priorities. The system provides at least two addresses instead of a single address, allowing the terminal device to attempt opening them in sequence. This segmentation resolves the contradiction by improving reliability through multiple fallback options while maintaining manageable complexity through structured address configuration.

The patent implements beforehand cushioning by preparing multiple addresses in advance, including a primary address and backup addresses. When the terminal device receives the address information, it can immediately attempt to open the primary address and fall back to backup addresses if needed, without requiring real-time decision-making or user intervention. This prior preparation ensures high reliability while keeping the system relatively simple.

The patent applies local quality by providing different address configurations for different operating systems (e.g., Android and iOS). The system determines the operating system type and selects appropriate addresses tailored to that platform. This resolves the contradiction by improving adaptability through platform-specific optimization while managing complexity through targeted configuration rather than universal complexity.

The patent implements universality through a unified address information receiving mechanism that works across multiple operating systems. The same basic flow (receiving address information, determining OS type, selecting addresses, attempting to open) is applied universally, while the specific address values differ by platform. This maintains simplicity in the overall system architecture while achieving multi-platform adaptability.

The patent implements feedback by having the terminal device attempt to open the download page and detect whether the operation succeeds. If the first address fails (e.g., due to missing application store), the system receives feedback about the failure and automatically attempts the second address. This feedback mechanism maintains ease of operation for the user while significantly improving reliability through automatic fallback.

The patent applies preliminary action by pre-configuring multiple addresses and policies before the user initiates the download. The system already has the first and second addresses ready, along with the logic to select and attempt them in sequence. When the user simply taps to download, the system can immediately begin the fallback process without requiring additional user input, maintaining simplicity while improving success rate.
