How to use canvas flags in Android

In my application I want use this library : https://github.com/race604/WaveLoading
This library used canvas flags but not found in my project!

This flags is :

int sc = canvas.saveLayer(0, 0, mWidth, mHeight, null,
                Canvas.MATRIX_SAVE_FLAG |
                        Canvas.CLIP_SAVE_FLAG |
                        Canvas.HAS_ALPHA_LAYER_SAVE_FLAG |
                        Canvas.FULL_COLOR_LAYER_SAVE_FLAG |
                        Canvas.CLIP_TO_LAYER_SAVE_FLAG);

After search I found this solution : Can not find Canvas variables in API Level 28 But when change codes to int sc = canvas.saveLayer(0, 0, mWidth, mHeight, null, Canvas.ALL_SAVE_FLAG); or int sc = canvas.save(); not run any animation!

How can I fix it?
