Some 3rd party plugins could cause a conflict.

Inside project properties, there is a full-screen scale option, make sure it is set to 'yes'.

What I mean about high res images, make sure when they are created, make them very high resolution, it is okay to have large images and shrinking them down then to use small images and making them bigger.

Do you have 3rd party plugins being used inside your project? (ones that did not come with Construct 2)?

Somewhere if I am not mistaken, there has been discussion for Google Services being added in the future. If this is true, I think it was Ashley that was discussing this topic.

What are you using to export? AppMobi, CocoonJS or Crosswalk?

Tablets with different resolutions might be your issue. Have you tried enabling "pixel rounding" in the C2 project properties?

Might also want to check to make sure full screen scaling is on as well.

Also, try to remember always make your images as high as resolution as possible, you can always shrink images, making them bigger does not always pan out.

If I were you, I would use this user made Facebook plugin, it has many more features than the one that comes with Construct 2. Here you can specify permissions in events.

I am slightly confused. Is it the permissions inside the game when you log in with Facebook? Or inside C2?

what is "id_user"? You didnt specify what the value of id_user is, so it will return null. You are selecting something that doesn't even exist, which is selecting " ", an empty value.

You will need something like this:

$id_user = $_GET['id_user'];[/code:cj5ztuez]

Within Construct, you will need to add that parameter to your request URL to something like this:

[code:cj5ztuez]Request "http://localhost/mygame/myscore.php?id_user=" &WHATTHEUSERIDIS" (tag "MyScore")[/code:cj5ztuez]

Within Ludeis CocoonJS lack of Memory Management, that is not possible.

Have you tried exporting with the new Crosswalk?

Android 4.0 or higher is supported. I just looked, however even though 4.0 is supported, it does not mean that the device will run it at great speeds. It all depends on the devices processing power.

It could also be, that the device being tested on, has its GPU blacklisted, I believe in some cases.

I believe that Crosswalk utilizes Android 4.2 or higher. Any version lower then that may have compatibility, stability and performance issues.

As for sound, may I ask for more of a description of what you define as "terrible"?

Edit: Sorry, Android 4.0 or better is supported. Depending on the age of the device, may make apps run more slowly.
