A page refreshing method of an Android application

Abstract

The invention discloses a page refreshing method of an Android application. When the service operation is executed in a first page, a broadcast receiver of a second page is used for monitoring a broadcast transmitter of the first page, and after the broadcast is monitored and when the second page is in the activated state, the refreshing instruction is generated according to the broadcast so as toexecute the corresponding refreshing operation on the second page. The invention further discloses a page refreshing device and system of the Android application and a computer readable storage medium. Visibly, the monitoring process is realized by using the broadcast receiver of the page; the broadcast receiver does not exceed the life cycle of the page; therefore, the problem of memory leakageis avoided, in addition, the page does not execute refreshing immediately after receiving the broadcast, but refreshing is executed only when the page is in the activated state, so that the problem ofoverlarge memory cost caused by simultaneous refreshing of a large number of pages is avoided, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a page refresh method, device, system and computer-readable storage medium for Android applications. Background technique [0002] We often encounter such a business scenario: jumping from a page A to page N (with one or more pages in the middle), and completing a certain business logic on page N, and then returning to page A, on the page Execute page refresh or other business logic when visible in A life cycle. The ideal situation is: refresh the page when it is visible in the life cycle of page A, and do not refresh when page A is not visible. [0003] The traditional technical solution is: create a singleton Z with a global life cycle, page A registers a listener to Z, when page A jumps to page N, page N executes business logic operations, and passes through Z after the execution is completed Notify all pages registered with listeners (including page A), and page A performs ...

Problems solved by technology

[0006] The main purpose of the present invention is to provide a page refresh method, device, system, and computer-readable storage medium for Android applications, aiming to solve the problem that a large number of pages in the traditional page refresh method register listeners in a single instance, which may easily cause memory leaks , and because a large number of pages will perform refresh operations immediately and simultaneously after monitoring the execution of a certain business logic, this greatly increases memory overhead and even causes technical problems such as crashes
