can't find referenced method 'int save(int)' in library class android.graphics.Canvas

[sune6]

compileSdkVersion=28时，release模式下会报can't find referenced method 'int save(int)' in library class android.graphics.Canvas，在proguard-rules.pro文件中加入-dontwarn com.mylhyl.zxing.scanner.**能暂时解决，出错原因：QRCodeEncoder.java第331行，canvas.save(Canvas.ALL_SAVE_FLAG)这个方法已经被remove了

@mylhyl The error still exits in com.mylhyl:zxingscanner:2.1.4.
“canvas.save(Canvas.ALL_SAVE_FLAG)” in QRCodeEncoder.
