Drawing app for my phone

Hello, I only have an android phone to draw on and I’m having trouble finding an app I can use. I used to use Adobe sketch and it was perfect but they shut that app down. Here is what I am looking for. I need a vector app i can import pictures into with layers. But I also need to be able to set the canvas size. I have found great apps for vector but I cannot set the canvas size and I have found apps where you can set the size but they are bitmap. I do stippling art and its important that it’s vector so I mess with it in Illustrator. Does anybody know of an app I can use?
