Question

我在JSON buildRequestBody（OutputStream os）方法中的代码中使用以下行将引发EDT违规。请告知是否有使用错误。请参阅附件中的日志。

代码：

if (a.getSign() != null) {
body
+= ",\n           \"SignatureData\": \n"
+ "           {\n"
+ "            \"SignatureImage\": \"" + Base64.encodeNoNewline(EncodedImage.createFromImage(a.getSignature(), false).getImageData()) + "\"\n"
+ "           }\n";
} else {
body += "\n";
}

EncodedImage出于性能目的而执行了边界EDT违规。 EDT违规代码会发送误报，因为我们不知道两者之间的区别。

这可以，并且不会在设备上引起问题。

使用EncodedImage.createFromImage方法
