Android wechat image sharing function

As we all know, there are many ways to support image sharing through wechat official sharing SDK. The official link can be viewed directly and will not be repeated.

The problem to be solved in this article is to share local pictures with QR code to wechat friends and circle of friends. Circle of friends pictures can be recognized by long press. Pictures of wechat friends dialog box can be recognized normally on IOS, but not on Android. Why?

The following quote from netizens:

After analysis and function comparison, there are two image browsing methods in the Android wechat app, image preview and the open view (with identification action) page after the image is sent locally. The preview picture function does not include the recognition function of long press gesture. Careful observation shows that IOS devices send QR code pictures to chat records. Android opens the preview function, and long press does not have QR code recognition function. However, when Android saves the picture and sends it again, it can be recognized. There is no problem with the picture, But the functional implementation of wechat Android version is not equal to that of IOS.

Through the action of the system_ Send component can solve the above problems.
