Hello, Good morning everybody.
Im curious about 2 solutions convert `dp` to `px`
Solution 1:
```fun Int.dpToPx(context: Context): Int {
    return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, this.toFloat(), context.resources.displayMetrics).toInt()
} ```

Solution 2:
```fun Int.dpToPx() = (Resources.getSystem().displayMetrics.density * this + 0.5f)```

so Which once is correct for multiple screen? Thanks.

aside from the 0.5 adjustment they're the same, but yes, use :one:

No, they're not the same, the second one doesn't work correctly with configuration changes.

ah I thought I read context.resources in that - i instinctively ignored the getSystem

yes, don't use the second solution, period

context.resources.displayMetrics would be equivalent but still less clear than the first solution
