This error seems to be happening only on Samsung phones using Android 6.0.1. or 7.0:

推荐答案

对我来说，最简单的解决方案是在EditText中覆盖此方法.希望三星有一天能解决它.

For me easiest solution was to override this methods in EditText. Hope Samsung will fix it one day.

override fun performLongClick(): Boolean {
    try {
        return super.performLongClick()
    } catch (e: NullPointerException) {
        return true
    }
}

override fun performLongClick(x: Float, y: Float): Boolean {
    try {
        return super.performLongClick(x, y)
    } catch (e: NullPointerException) {
        return true
    }
}
