我使用Firebase存储来保存照片。但我的onSuccess在上传完成之前被调用
错误:
java.lang.IllegalStateException: Task is not yet complete

代码
val storage = FirebaseStorage.getInstance().reference
storage.child("images/profile/${mAuth.currentUser?.uid}.jpg").putBytes(data)
.addOnProgressListener {
val progress = 100.0 * it.bytesTransferred / it.totalByteCount
dialog.incrementProgress(progress.toInt())
}
.addOnSuccessListener {
user.profile = it.storage.downloadUrl.result.toString()
registerDataWithoutPhoto(user)
}
.addOnFailureListener {
toast("Error uploading photo. You can update your profile pic later in the profile section.")
registerDataWithoutPhoto(user)
}
为什么在任务完成之前调用成功侦听器?
仅供参考:早前几次工作完全正常。这是一个突然的错误。
答案 0 :(得分:3)
it.storage.downloadUrl
(javadoc)只有在参考的下载URL可用后才会返回完成的任务。您的代码不等待该任务完成。相反,它试图立即获得结果,并且该访问正在抛出异常。相反,您应该使用该任务上的侦听器,就像使用putBytes
返回的任务一样。
