Aperantly the Android API has gesture detection built in, can you guys check if you can implement something like this ?

SDL has a similar thing with its "dollar gesture" API, but I haven't looked into implementing that yet - partly because it seems a little 'heavy'.

Yeah, when you think about it the idea itself has some really complex stuff.. Maybe all the lover needed to do would be something like, creating a gesture (with some kind of gesture listener) in an app, then the app would save the gesture (with all the movement and the velocity data) into a file and then to use that gesture we'd need to load the gesture file. We can't code a gesture per se, we create it with a listener and then load the gesture file. But maybe adding some options to ignore gesture velocity or gesture time intervals and all those other gesture-related technical stuff would be smart too.

What do you think ?

It's really hard!

Personally I find it too much of an overkill. I would assume that it seldomly happens to that a new gesture is required. Also it should not be too hard to detect gestures in Lua code. Maybe we could create a "Share a Gesture" thread similar to the "Share a Shader" thread at http://www.love2d.org/forums/viewtopic.php?f=4&t=3733.

Are there any known unoptimized spots in this android port?

I don't know any except the final size of the APK file when you build for both armeabiv and armeabiv7 archs.

Have a look at the bug tracker: https://bitbucket.org/MartinFelis/love- ... tatus=open

There seems to be a problem with sound for some people: https://bitbucket.org/MartinFelis/love- ... c-is-laggy
Also there is some unneccessary copying of the .love file: https://bitbucket.org/MartinFelis/love- ... amelove-to

For most cases however I think it is in good shape.

It's hard on both sides, it's actually really complicated to detect gestures, we could say that coding gestures is as hard as coding physics from scretch.
This is what I have so far for zooming in and out on a rectangle ( not tested ):

Can someone teach me how to build an apk with the source, step by step please, I want to test out Display Metrics

You do not need to build an apk yourself. You can use the standard alpha .apk which will run any Love game extracted to /sdcard/lovegame.
