Hello, everyone, I need to ask for advice with some questions, thanks in advance.
First, I find that the path is always slower than the finger touching point when I'm drawing with finger touch, who could tell me why please?? Is it effected only by hardware ??
Second, I need to achieve the function that the path and the finger touch are synchronized, who could give me some advice ??
And I tried ways below:
1. I changed View to SurfaceView at Sumsung GT-N8000(Android 4.1.2), but the drawing path does't become faster.
2. I run my demo at Nexus 5(Android 5.0), but the path is still slower than the finger touching point. (At the Android Official Document, it metions that 'Android 4.3 builds on the performance improvements already included in Jelly Bean — vsync timing, triple buffering, reduced touch latency, CPU input boost, and hardware-accelerated 2D rendering — and adds new optimizations that make Android even faster')
Thank you very much~~
