IllegalArgumentException: Invalid Region.Op - only INTERSECT and DIFFERENCE

异常产生缘由

部分接口被废弃，当targetSDKVersion升级28检查更严格，google被废弃接口参考文档:

产生条件

一、targetSDKVersion为28
二、android系统9.0设备
二、clipPath、clipRect、clipOutPath部分带参接口被废弃android

修改方案

if(Build.VERSION.SDK_INT >= 26){
     canvas.clipRect(mClipBounds);
 }else {
     canvas.clipRect(mClipBounds, Region.Op.UNION);
 }
复制代码

if(Build.VERSION.SDK_INT >= 26){
     canvas.clipPath(mPath0);
}else {
     canvas.clipPath(mPath0, Region.Op.XOR);
}
复制代码

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    canvas.clipOutPath(mPath);
} else {
    canvas.clipPath(mPath, Region.Op.INTERSECT);
}
