我正在尝试将图像上传到Firebase，但出现此错误：
无法解析方法getDownloadUrl（）
我浏览了几个主题，但是我无法正确实现针对我的代码提出的解决方案！ Firebase对我来说是一个相当新的概念，请尽量不要对我的无知强硬。
我已经花了几个小时来摆弄这段代码，但是我仍然陷于困境。需要帮助
StorageReference filepath=mStorageReference.child("profile_image").child(uid+".jpg");
final StorageReference thumb_file_path=mStorageReference.child("profile_image").child("thumbs").child(uid+".jpg");
//------STORING IMAGE IN FIREBASE STORAGE--------
filepath.putFile(resultUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
@Override
public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {
if(task.isSuccessful()){
@SuppressWarnings("VisibleForTests")
final String downloadUrl= task.getResult().getDownloadUrl().toString();
UploadTask uploadTask = thumb_file_path.putBytes(thumb_bytes);
//---------- STORING THUMB IMAGE INTO STORAGE REFERENCE --------
uploadTask.addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
@Override
public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> thumb_task) {
@SuppressWarnings("VisibleForTests")
String thumb_download_url=thumb_task.getResult().getDownloadUrl().toString();
if(thumb_task.isSuccessful()){
Map update_HashMap=new HashMap();
update_HashMap.put("image",downloadUrl);
update_HashMap.put("thumb_image",thumb_download_url);
//--------ADDING URL INTO DATABASE REFERENCE--------
mDatabaseReference.updateChildren(update_HashMap).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if(task.isSuccessful()){
mProgressDialog.dismiss();
Toast.makeText(SettingActivity.this, "Uploaded Successfuly...", Toast.LENGTH_SHORT).show();
}
else{
mProgressDialog.dismiss();
Toast.makeText(getApplicationContext(), " Image is not uploading...", Toast.LENGTH_SHORT).show();
}
}
});
}
else{
mProgressDialog.dismiss();
Toast.makeText(getApplicationContext(), " Error in uploading Thumbnail..", Toast.LENGTH_SHORT).show();
}
}
});
}
else{
mProgressDialog.dismiss();
Toast.makeText(getApplicationContext(), " Image is not uploading...", Toast.LENGTH_SHORT).show();
}
}
});
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
Exception error = result.getError();
}
}
}
请稍作解释。
随便！
