Is there an easy way to determine if device screen supports portrait / landscape views ? 

(We need this in order to provide different settings to user)

Until recently we used check similar to this one:

if OS >= "6.0" && AccelerometerSensor.isSupported()

but this code fails on the new Bold  9900 (which has  Accelerometer, but does not have landscape mode).

We are looking for solution which does not invlove checking device models manually ...

Thanks in advance !

Hi ,

Generally the devices which support TouchScreen are have both the modes.

So that you can go with TouchScreen.isSupported()

Thanks.

Does not work - example Bold 9900 

[pradeep_ch]

Then you can try with both the combinations of screen resolution and TouchScreen.isSupportrd().

Thank you for your continiues offer to help us.

Do you have in mind a reliable solution which will work on current set of BlackBerry devices and (hopefully) new models ?  

On first glance your suggestions is much worse then checking device model directly.

don't know a solution myself, and as it is a good question i've escalated it.

You can use the DeviceCapability.isRotationSupported() method to determine this.  This class was added in BlackBerry Device Software version 6.0.

Is there a workaround to do this for OS5? What are the underlying parameters that the OS6 API polls?

[simon_hain]

as all acceleratometer devices with 5.0 support it there is no need for a separate check.

[precisionpete]

Except that some later devices do not. e.g. 9900. So a check is needed.

I'm trying to avoid building apps for specific devices and OSs. I want to build to a minumum OS and let later devices use that. It's a lot less work.
