ways to determine screen orientation

[nmyshkin]

First, I am using an older version of Tasker to produce apps for Android 2.1, so there is no Display > Test > Orientation option. Secondly, there is likely no accelerometer (device is e-reader), so there's nothing to query in that regard.

I currently change screen orientation using the Rotation Locker plugin. I guess I could establish in the task that sets orientation a global variable that I could use in a different task to detect the current orientation.

Is there a more general approach? Suppose someone is rotating their screen by some other means/app. Is there any way to detect/query that?

Mmm......

adb shell dumpsys window | grep DisplayWidth  (with root)

returns (in portrait mode): DisplayWidth=600 DisplayHeight=800

and

returns (in landscape mode): DisplayWidth=800 DisplayHeight=600

so the system clearly knows what's going on with the orientation change brought about by Rotation Locker, even on this ancient device :-)

Looks like a simple Variable Search or Variable Section on a piped txt file should tell me what I need to know!

Does that version have Display -> Test Display -> Available Resolution? On my device it returns 1440x2792 in portrait and 2792x1440 in landscape.

If your version has the Java Function action, you can use Java to get the rotation. %rotation will be even when you are in portrait and odd when you are in landscape. 

        Test

        

    A1: Java Function 

        Return: display 

        Class Or Object: CONTEXT 

        Function: getDisplay

        {Display} () 

        

    A2: Java Function 

        Return: %rotation 

        Class Or Object: display 

        Function: getRotation

        {int} () 

        

    A3: If %rotation % 2 = 0

            

        A4: Flash 

            Text: Portrait 

            Long: Off 

            

    A5: Else 

            

        A6: Flash 

            Text: Landscape 

            Long: Off 

            

    A7: End If

Test actually appears only under Misc and there are no display-related options.

But this shell command thing turns out to be the ticket. It's easier than I thought and is fast (in Terminal execution was kind of slow so I was worried). I didn't even have to pipe the result to a txt file. I just used the "Store Result in" option for the Run Shell task and created a variable %Orientation. Then all I had to do was add one more line to rotate an image in the image buffer 90 degrees to the right If %Orientation did not match the conditions for Portrait. Simple--and a general solution for this device.

Thanks for your suggestions. No JAVA option either (although there is the JavaScript one), but the shell command is way easier and anyone who would want to install the app would have to be rooted so that's no issue.
