问题 Is it possible to add OG:video data to the head of a website so that whatsapp and facebook can play the video inline? I have currently only seen this working with youtube and instagram links. Whenever I copy the whole meta data from a working instagram post and paste it into my document the facebook debugger picks up on all the data. However whatsapp only shows the thumbnail and not the inline video. Is this feature only for whitelisted domains like youtube or is this something anyone can do?

问题 I'm fairly new to android and have only really been using eclipse for some basic Blackberry work so I was curious if I could pick a few expert's minds for any suggestions/pointers on the workspace/project setup you use for dual platform support projects in eclipse? I've found about 80% of my code is common between Blackberry and Android so it's this 20% I'm needing to address. My current thinking is to have one workspace with shared source in multiple projects via setting them in the source

问题 We are developing multiple intranet websites with different functionalities. We plan to have a root project (with some basic functionality) from which the user can navigate to the different other projects. We plan that all projects of this kind should use the same Layout _Layout.cshtml . To accomplish this we tried to link the _Layout.cshtml from the "side-projects" to the root project.

I want to either use my data folder or my cache folder since neither of these require any permission to access. The code which I use to write my image to file (and I specify the MODE_WORLD_READABLE so that other apps can read them):

问题 I have a single android app with a custom logo, some custom json service endpoints, occasional custom text, and possibly a custom color scheme. For my client this particular app will need to be rebranded and distributed as an entirely different app about 5-10 times over.

First off, how can I share projects in the sense that one project will hold all
