call requires api level 24 (current min is 16): android.icu.text.DecimalFormat # DecimalFormat

Navigation
0

I was trying to format the output numbering of the calculations data in the textview, to two decimal places. I found the DecimalFormat code, but it did not work for me.

I was already in Gradle and changed the minimum SDK to 16, but it still did not work. Can anyone help? Thank you!

According to the documentation, android.icu.text.DecimalFormat#DecimalFormat is only available for API 24+ and will not work in your project, unless you change the minSdkVersion to 24.

You may need to simply insert the DecimalFormat that your project. Just import this class: 

import java.text.DecimalFormat

And not this: 

import android.icu.text.DecimalFormat

See more in the documentation .
