The best way to do things is to use sync. If you wish do use other methods it would become complicated.

What you are trying to do makes no sense to me.

There is no Oracle Java for Android. Adobe stopped supporting Flash Player on Android 4.1 and higher.

Firefox Sync provides URLs in the form of history and bookmarks. Content of the pages is not synced.

Files on the system can be browsed using the file:/// protocol. Though using it as a way to view cached sites is almost certain to fail due to security restrictions. Only the simplest sites are likely to work in this manner.

Thanks, this helps me understand the difficulties I've had.

Clearly the industry needs to think and work more toward making online and offline work together better for the user. The new mini pads are ideal for use in the field, and workers need to be able to do their jobs even when connections are lost temporarily.

I'm working on ways for people to have disaster survival and recovery information, even when electricity and Internet are totally down (as happened to thousands during the recent Hurricane Sandy). Provide offline access to maps, evacuation routes, how to find and purify water, emergency medicine, working with national and local relief efforts, lessons from past disasters -- using devices that hold gigabytes of information, are self-contained, easily portable, not fragile, consume little power for easy manual, solar, other telephone-style recharging, are usable even in total darkness, and can copy websites so that existing information does not need to be reformatted unnecessarily. This is essential, and the bad job now being done to provide this information is (and should be recognized as) a serious security issue.

I'm looking at Dropbox. The current Android version lets you mark files as favorites, causing them to be downloaded for offline use. And this project doesn't need video for now.
