how to detect accessibility settings on android is enabled/disabled

Question

I\'m particularly interested in high contrast text, color correction, and magnification settings. I did some research online, couldn\'t fi

Answer 1

Though reflection solution helps with some devices I was unable to get "isHighTextContrastEnabled" via reflection on my OnePlus 5 device. So I ended up with another method when reflection fails. Just rendering text on a bitmap and then manually checking if there is a specific color (different from black and white) in the bitmap (cause in "High Contrast" mode it will be black and white).

Here is the code in Kotlin:

private fun isHighTextContrastEnabledWithBmp(): Boolean {
    val bmp = Bitmap.createBitmap(10, 10, Bitmap.Config.ARGB_8888)
    val canvas = Canvas(bmp)
    val testColor = Color.GREEN

    val paint = Paint().apply {
        color = testColor
        textSize = 5f
    }

    canvas.drawText("1", 0f, 10f, paint)
    val pixels = IntArray(bmp.width * bmp.height)
    bmp.getPixels(
        pixels, 0, bmp.width,
        0, 0, bmp.height, bmp.width
    )
    val result = pixels.any { it == testColor }.not()

    return result
}
