Hi,

Can someone tell me how this will be done, and which runtime it will use on release?

Currently owning a Blackberry Z10 which uses Android 2.3 runtime (in the next update this will be 4.2.2), ported apps can be submitted to the appstore, or you can sideload the *.bar files (converted *.apk files) on the Phone.

Will this be the same on Jolla, or how should I see this?

Thanks!

Probably the same.

Using magic and a touch of alien dalvic. But mostly by magic.

Black magic? (I don't wanna sound racist tho)

as far as we know, it'll be not like the blackberry.
You don't need to convert anything.
Just grab a .apk file, and you're ready to go.
The Android apps will be running within a sandbox. But that's all we know so far.

That's good to know, especially that it won't need a conversion!
Although I'd definately wan't to run native apps, sometimes (like I experience on the Z10) the native apps aren't available yet, or won't come available at all.

wondering how it deals with the three (ugly) buttons.

Nokia should do this for the initial release of Harmattan!

What Nokia should do, is not to let die the MeeGo at first point, and it should not sold itself to Microsoft...

I had a BlackBerry Z10 and the central problem with that approach to running Android apps was that only free apps were really legit, because of the inability to access the Google Play Store to buy paid apps. Hopefully Jolla will come up with a solution, preferably one that allows you to take apps directly from your Android device or somehow access the stuff you've already bought. The third party store solutions mentioned by Jolla sound interesting

The second problem is the frequent update cycle of the Android versions and the apps that it runs. Keeping up with Google is no easy task. And if you haven't been on an Android device lately, the pace of development is unbelievably fast compared to Meego/Maemo/most anything else. Every day I have several apps updating on my Android device (HTC One). Jolla has to hit Android compatibility out of the park, because the quality, variety, and availability of apps simply will not be enough without the addition of Android apps.

I, for one, would be super happy with a Jolla phone with great Android compatibility, but with the great Sailfish OS UI, more openness, unique styling, and well, something a little more Unlike that's great for single handed use.
