Not allowed custom density in emulator?

[Tomáš Procházka]

Why is not allowed to enter custom LCD density in emulator? There is combo with default values, but I think that should be possible enter custom value if I wan to emulate real device.

[Michael Wright]

The Abstract LCD Density option maps to the densities used by the framework, so this is essentially a drop down for ldpi, mdpi, tvdpi, etc. (docs). While real devices do have different densities, they'll actually get "rounded" to the nearest one of these values for dp calculations, which I believe is the only place this value is used.

Hope this helps,

Michael

What Michael said.

I'll add one more thing: a device must report one of the bucket densities to pass CTS. So all compatible devices out there, despite all having screen density that are (slightly) different from one of those bucket densities all report a density from this list.

Please do not send me questions directly. Thanks!

On the CTS side of things, are new densities retroactive?  For instance does TVDPI make any sense to a 2.2 device?

[Xavier Ducrohet]

I don't think so.
