[android-developers] Re: Compatibility mode issues on 4.x

Now I also tested with a tablet emulator with 10.1 diagonal. The smallest side should be something around 7 inches. And I still get compatibility mode only until max. 320 dp, like in the Nexus 7.

The problem is the Nexus 7. The smallest side is 4.72 inches. But I can put max. 320 dp in the manifest for it to go in compatibility mode. With 321 it doesn't work anymore.

Let's just think about this for a minute.

320 dp is 2 inches.

Here are the specs for your Galaxy Nexus:

1280×720 px *(316 ppi)

So, we are interested in the smallest side.  That is 720.

720/316 = 2.27848101266 inches

So, it is rightly going into compatibility mode on your Galaxy phone since 2.27848101266 inches is longer than 2 inches.

Let's see what 2.27848101266 is in dp:

2.27848101266 * 160 = 364.556962026 dp

So, if you set it to 365dp or higher, then your phone should not go into compatibility mode.

Thanks.

I'm trying to force compatibility mode on tablets, for a certain app, because I don't work on it anymore - and currently it looks really really messed up on tablets.

According to the documentation:
http://developer.android.com/guide/practices/screen-compat-mode.html

There are many different options to set up in the manifest, to make it possible, to the user, to enable compatibility mode. This is not exactly what I want, but anyways, maybe worth to mention, these options didn't work. I couldn't find anything on the device to switch to compatibility mode. I used a Nexus 7 with 4.2.

Now there's the part which I need - and I also can't get it to work. To force compatibility mode, it I have to use this element:

<supports-screens android:largestWidthLimitDp="320" />

When I let the value 320 there, my Galaxy Nexus smartphone goes in compatibility mode. That is unwanted.
The Nexus 7 also does, this is good.
So I have to use bigger dp - But starting at 321, for some reason I don't understand, the Nexus 7 doesn't go anymore in compatibility mode.

Is this normal? According to what I read the dp of the shortest side of the Nexus 7 is more than 500, why then it stops on 321?

I would let it on 320, but I have optimized layouts for this screen size and don't want these to go in compatibility mode.

Thanks.
