[Android] React ART can't drawing the line dynamic. #14330
Description
I have used the panResponder to catch the points moved on the screen ,draw the path and display it. It is works well on iOS, but it doesn't works on Android.
Here is the code:
process the points
let d = new Path();
for(let i=0;i<this.arrUsedPoint.length;i++){
let p = this.arrUsedPoint[i];
if (p.type ==='start' ){
d.moveTo(p.x, p.y);
}else {
d.lineTo(p.x, p.y);
}
}
this.showPoints = d;
render method:
render() {
return (
<View style={styles.container} {...this._panResponder.panHandlers}>
<Surface ref={'lineView'} width={ScreenWidth} height={ScreenHeight}>
<Shape d={this.showPoints} stroke={'rgb(0,185,255)'} strokeWidth={this.nowR} />
</Surface>
</View>
);
}
This is it works on iOS, when I touch and moved ,it will display the line . and the points object will be correctly display ,notice the text : initial -> [Object object]
And this is it works on Android, we can see that the text will be changed to [Obejct objetct] ,but it can't display the line.
If i change the path like this: <Shape d={"M160 160 A 45 45, 0, 0, 1, 115 205"} stroke={'rgb(0,185,255)'} strokeWidth={this.nowR} />;, then it will draw an arc when first render on android.
is it a bug? or something important but ignored by me?
and attach the env of my demo.
