Java.lang.UnsupportedOperationException Android Studio

My app keeps on crashing on launch because of several errors.

1. java.lang.InvocationTargetException
2. java.lang.UnsupportedOperationException

Here is the logcat error for the second exception.

Caused by: java.lang.UnsupportedOperationException: Can't convert to ComplexColor: type=0x1

        ... 72 more

From the last line it says my error is from my MAFTextViewBold.kt file

class MAFTextViewBold (context: Context, attrs: AttributeSet) : AppCompatTextView(context, attrs){
init {
    applyFont()
}

private fun applyFont() {
    val typeface:Typeface =
        Typeface.createFromAsset(context.assets, "Montserrat-Bold.ttf")
    setTypeface(typeface)
}

}

What could be causing the error? It was compiling before but after I did a factory reset on Android Studio I could not ran my app. The erros started showing.

Answer

It turns out that the exceptions were brought by using a complex color that could not be translated. see the exception:

Caused by: java.lang.UnsupportedOperationException: Can't convert to ComplexColor: type=0x1


            

This color android:textColor="@color/aquamarine" can not be converted properly as applied in my MAFTextView class. Even on a normal TextView it still can’t be converted. I changed the color to black and my app was running again. Android Development always finds a way to amaze me. Just a color change throws two exceptions.smh
