I have read other posts with the same issue but I really don't understand where to put the code and what to do. Any help is appreciated.
private void StoringTextToFirebaseStorage()
{
Calendar callForDate = Calendar.getInstance();
SimpleDateFormat currentDate = new SimpleDateFormat("dd-MMMM-yyyy");
saveCurrentDate = currentDate.format(callForDate.getTime());
Calendar callForTime = Calendar.getInstance();
SimpleDateFormat currentTime = new SimpleDateFormat("HH:mm:ss");
saveCurrentTime = currentTime.format(callForDate.getTime());
postRandomName = saveCurrentDate + saveCurrentTime;
HashMap postsMap = new HashMap();
postsMap.put("uid", currentUserID);
postsMap.put("date", saveCurrentDate);
postsMap.put("time", saveCurrentTime);
postsMap.put("description", Description);
postsMap.put("image", downloadUrl);
PostsRef.child(currentUserID + postRandomName).updateChildren(postsMap)
.addOnCompleteListener(new OnCompleteListener()
{
@Override
public void onComplete(@NonNull Task task)
{
if (task.isSuccessful())
{
SendUserToMainActivity();
Toast.makeText(PostActivity.this, "Post Uploaded", Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
}
else
{
String message = task.getException().getMessage();
Toast.makeText(PostActivity.this, "Error Occurred: " + message, Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
}
}
});
}

This is my code. downloadUrl is meant to be the link of the image and is meant to be in the "image" postsmap.put.
downloadUrl = task.getResult().getStorage().getDownloadUrl().toString();
For some reason it saves as com.google.android.gms.tasks.zzu@ and not as a link. I looked at https://firebase.google.com/docs/storage/android/download-files#download_data_via_url but I really don't understand what to do, so could someone please help me by telling me what to replace? Here is my whole code:
private Toolbar mToolbar;
private ProgressDialog loadingBar;
private ImageButton SelectPostImage;
private Button AddPostButton;
private EditText PostDescription;
private static final int Gallery_Pick = 1;
private Uri ImageUri;
private StorageReference PostsImagesReference;
private DatabaseReference PostsRef;
private FirebaseAuth mAuth;
private String Description;
private String saveCurrentDate, saveCurrentTime, postRandomName, downloadUrl, currentUserID;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_post);
mAuth = FirebaseAuth.getInstance();
currentUserID = mAuth.getCurrentUser().getUid();
PostsImagesReference = FirebaseStorage.getInstance().getReference();
PostsRef = FirebaseDatabase.getInstance().getReference().child("Posts");
SelectPostImage = (ImageButton) findViewById(R.id.select_post_image);
AddPostButton = (Button) findViewById(R.id.add_post);
PostDescription = (EditText) findViewById(R.id.post_description);
loadingBar = new ProgressDialog(this);
mToolbar = (Toolbar) findViewById(R.id.update_post_page_toolbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setTitle("Update Post");
SelectPostImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{
OpenGallery();
}
});
AddPostButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{
ValidatePostInfo();
}
});
}
private void ValidatePostInfo()
{
Description = PostDescription.getText().toString();
if(ImageUri == null)
{
Toast.makeText(this, "Please select image", Toast.LENGTH_SHORT).show();
}
else if(TextUtils.isEmpty(Description))
{
Toast.makeText(this, "Please say something about your image", Toast.LENGTH_SHORT).show();
}
else
{
loadingBar.setTitle("Post Uploading");
loadingBar.setMessage("Please Wait");
loadingBar.show();
loadingBar.setCanceledOnTouchOutside(true);
StoringImageToFirebaseStorage();
}
}
private void StoringTextToFirebaseStorage()
{
Calendar callForDate = Calendar.getInstance();
SimpleDateFormat currentDate = new SimpleDateFormat("dd-MMMM-yyyy");
saveCurrentDate = currentDate.format(callForDate.getTime());

}
else
{

}
private void OpenGallery()
{

}
@Override

{

if (requestCode==Gallery_Pick && resultCode==RESULT_OK && data!=null)
{

SelectPostImage.setImageURI(ImageUri);
}
}
@Override

}
return super.onOptionsItemSelected(item);
}
private void SendUserToMainActivity()
{

startActivity(mainIntent);
}
}
updated code:
final StorageReference filePath = PostsImagesReference.child("Post Images").child(ImageUri.getLastPathSegment() + postRandomName + ".jpg");
filePath.putFile(ImageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
@Override
public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task)
{
if (task.isSuccessful())
{
SendUserToMainActivity();
//downloadUrl = task.getResult().getStorage().getDownloadUrl().toString();
PostsImagesReference.child("Post Images").getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
// Got the download URL for 'users/me/profile.png'
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception exception) {
// Handle any errors
}
});
Toast.makeText(PostActivity.this, "Post Uploaded", Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
StoringTextToFirebaseStorage();
}
else
{
String message = task.getException().getMessage();
Toast.makeText(PostActivity.this, "Error Occurred: " + message, Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
}
}
});
}
