当我尝试使用downloadUrl.result检索上载的downloadUrl（上传正常）时，应用程序崩溃。使用downloadUrl.toString()时，该应用程序不会崩溃，但这并不能为我带来字符串形式的downloadUrl。我曾在论坛上读过人们有类似问题的论坛，但我无法解决。预先谢谢你
private fun uploadImageToFirebase(){
val profileImageRef = FirebaseStorage.getInstance().getReference("profilepics/" + System.currentTimeMillis() + ".jpg")
if (uriProfileImage != null) {
profileImageRef.putFile(uriProfileImage!!)
.addOnSuccessListener { taskSnapshot ->
profileImageUrl = taskSnapshot.metadata?.reference?.downloadUrl?.result
}
.addOnFailureListener { e ->
Toast.makeText(context, e.message, Toast.LENGTH_SHORT).show()
}
}
}
调试：
---------崩溃开始

答案 0 :(得分：0)
我现在解决了。任务尚未完成。这就是为什么我无法检索downloadUrl的原因。添加了一个OnCompleteListener ...
taskSnapshot.storage.downloadUrl.addOnCompleteListener{
task -> if(task.isSuccessful){
profileImageUrl = task.result
}else{
Log.d("Crash", "Crash starts here")
}
答案 1 :(得分：0)
尝试一下：
storageReference.putFile(postImageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
@Override
public void onComplete(@NonNull final Task<UploadTask.TaskSnapshot> task) {
if (task.isSuccessful())
{
String downloadUri = task.getResult().getDownloadUrl().toString();
Map<String, Object> postMap = new HashMap<>();
postMap.put("image_download_uri",downloadUri);
postMap.put("post_title",title);
postMap.put("current_user_id",current_user_id);
postMap.put("current_time",currentTime.toString());
postMap.put("timestamp", FieldValue.serverTimestamp());
