已编辑：原标题中的“闪一下”实际上是app自身的dialog引起，避免误导去掉

所有信息都在了，麻烦尽快反馈，谢谢

PS：框架类型是 Android 客户端原生，非小程序

1. 分享本地bitmap到微信，sendReq 返回 true，却没有打开微信会话窗口
2. 同样的代码、调用栈，仅构建WXImageObject的bitmap资源不一样，就会导致失败（但两次sdk输出的日志完全一样），看起来sdk内部未发生异常，见日志部分

附：两次分享唯一差异

成功时，bitmap byte count = 9836640
失败时，bitmap byte count = 10368000
均未超出上限 26214400

附：SDK 版本

com.tencent.mm.opensdk:wechat-sdk-android-without-mta:6.7.0
