Android Question Non-English characters and MeasureMultilineTextHeight in API28

KZero said:

i found the cause in api 28
setFallbackLineSpacing is Enabled by default (on many devices, thats why the non-latin text looks correct on some device and some devices not)

this code fixed the measurement problem

B4X:

    Dim P As Phone
    If P.SdkVersion >= 28 Then
    Dim Ref As Reflector
        Ref.Target = label1
        Ref.RunMethod2("setFallbackLineSpacing","False","java.lang.boolean")
    End If

the only problem with this code that it makes the Arabic lines bit close to each others but it's pretty acceptable for me
i'm not sure if MeasureMultilineTextHeight can be called with custom line spacing parameter using reflection or inline java code, it will be an extra option to make the measured string looks bit better.

    Dim P As Phone
    If P.SdkVersion >= 28 Then
        Dim Ref As Reflector
        Ref.Target = lblTheory
        Ref.RunMethod2("setFallbackLineSpacing","False","java.lang.boolean")
    End If
    lblTheory.Text = CS.PopAll
    lblTheory.Height = su.MeasureMultilineTextHeight(lblTheory, lblTheory.Text)
