Question

I\'m trying to compile my Project,but in there is some error

Android manifest.xml

Answer 1

As already answered earlier, roundicon was first introduced in API Level 25. If you want to maintain a lower API level without increasing to >= 25 then

go to the mipmap directory and delete the subdirectory "ic_roundicon" with all its files

delete @res/mipmap/ic_roundicon
