应用无法提交,我提交时提示“图片格式错误”,我该如何处理?

安卓规范中规定:应用apk文件中的IOCN必须是PNG格式。请您对apk内部的ICON格式进行检查

相应的格式修改必须用格式修改器进行修改,直接修改图片的后缀名是无法更改图片的格式的。

检查应用ICON是否为PNG格式,可以使用aapt工具,执行下面的命令:
aapt dump badging <apk包的路径>
检查输出内容中的所有声明的icon对应的图片是否是PNG格式

如下图红色字体部分:

请将上述内容交由开发人员查看。

如问题仍未解决,请说明您的问题详情、并将所有icon文件压缩打包后邮件至developer@xiaomi.com.
