I have had to work around this for a while.
This is what i have:
As staded abovr, Puffin, which is paid, but works very well
I also have an old verison of flash that i loaded manually (you can find the apk all over)
Once installed, Firefox will work, but FF crashes a lot.
Lastly, there is Dolphin, with their jet pack, (free), also works well - their site also points you to a flash apk.
But, since flash is old, it will have security flaws, and will be buggy.
Generally, using one of the above, give me the ability to view camd that use flash
