Change 202615 had a related patch set uploaded (by BearND):
[WIP] Link previews (prototype 1)

https://gerrit.wikimedia.org/r/202615

@Vibhabamba: Here is an updated apk of prototype 1

DONE:

• Removed the X button
• Increased type size for page text extract to 16sp
• 60/40 proportion for page text extract vs. image
• Tapping anywhere within the card (including title link) takes you to the page
• No scroll bars should be seen in the left area

Still TODO:

• Bring back scrolling of extract text.
• Swipe up: go to page
• Swipe down: dismiss

Also wanted to mention that I consider the bug (preview missing text) not critical to the user testing. This one can wait until later IMO.

@bearND downloaded. thank you. This comment date is correct as we discussed.

@bearND @Dbrant
In the most current prototype, the actual width of the image area is decreasing with the animation.
The image area must be fixed, the animation needs to occur within that area.

• Tapping anywhere within the card needs to go to the article.
• Ken burns zoom for preview cards needs to be reduced to 50% of current value.

Here's the updated apk from @Dbrant:

and his comments from email:

"I was able to implement the sentence manipulation that we discussed, namely: display only one sentence by default, but if the first sentence is shorter than four lines, then append the second sentence.

I also added simple swipe gestures to the card: swipe down to dismiss, and swipe up to go to the article. The problem is that the card itself doesn't "follow" the swipe motion dynamically, so we may have to invent something more elaborate if we really want the swipe interaction to work."

I wonder if we should drop the Ken Burns effect for the preview. Having this extra animation in addition to the animation of the dialog itself moving up seems pretty jarring to me, and distracts from a quick lookup.

List of tweaks based on Dmitry updated text display patch:

Prototype 1:
With the limited text we are generating (per Dmitry's script from yesterday), height of the overall card can reduce by 20%
Right margin increase by 10 px
Title area height increase by 20 px
Tapping anywhere on the card takes you to the target article

Prototype 2:
Use a 20% black opacity behind the text (Between text and image)
Increase type size (and leading) by 4 points.
We could eliminate the ken burns effect from this version.

@Vibhabamba:

"Tapping anywhere on the card takes you to the target article"

Was already done. Or where does it not work?

Here are a few screenshots of the changes in prototype 1:

@bearND how might I download the new apk files?

Just uploaded; here:

@bearND thank you.
