### Android canvas = Canvas(bitmap)抛错：java.lang.IllegalStateException: Immutable bitmap passed to Canvas constructor at android.graphics.Canvas.<init>(Canvas.java:114)，Kotlin ###

抛错代码：

val bitmap = BitmapFactory.decodeResource(resources, R.mipmap.pic)
            val canvas = Canvas(bitmap)

解决：

val bitmap = BitmapFactory.decodeResource(resources, R.mipmap.pic).copy(Bitmap.Config.ARGB_8888, true)
            val canvas = Canvas(bitmap)
