I'm following a tutorial teaching how to upload images to Firebase. At certain moment the instructor will write the code to get the download URL after uploading by using getDownloadUrl() method from UploadTask.TaskSnapshot, but for me, this method doesn't exist.
Based on another code I found, I tried the following:
OnSuccessListener<UploadTask.TaskSnapshot> upload = new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
ChatroomMessage message = new ChatroomMessage(null, mUsername, taskSnapshot.getDownloadUrl());
mMessagesDatabaseReference.push().setValue(message);
}
};
Because it is similar to what's shown in the documentation, but I didn't understand it very well. How to implement it?
Getting below error please help

So for some reason each users image in the table view takes about 10-15 seconds to load which is very long. Here is my code but bear with me there are a lot of for loops. Quick sum of all the loops, the first loop gets every single Username and photoURL pair in the firebase database then the other for loop gets all the users the logged in user if following. The two for loops are then compared and if the array with the username and photoURL contains a username in the array with all the users the logged in user is following, the end result with all the appropriate photoUrls are stored in an array. That array is looped into data and finally that data is looped into the cell.imageview. I know its a lot but it was the only solution I could find to my problem.

Firebase SDK for Cloud Functions Migration Guide: Beta to version 1.0
In the code provided we need to remove the variable (event) and replace it with (change,context): this is the snippet of my working code:
exports.emojify =
functions.database.ref('/messages/{pushId}/text')
.onWrite((change,context) => {
console.log("emojifying!");
// Get the value from the 'text' key of the message
const originalText = change.after.val();
const emojifiedText = emojifyText(originalText);
// Return a JavaScript Promise to update the database node
return change.after.ref.set(emojifiedText);
});

I just tried to run the app and it crashed with the aforementioned message. The quick solution was to add permissions in the AndroidManifest.xml file like this:
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Do you think that they should be included in the solution code, as well?
unable to login using either email or gmail authentication it displays DEVELOER ERROR
getDownloadUrl() does not seem to exist anymore. Looking at the firebase-documentation it looks like this method is called on the reference now not taskSnapShot. I have tried the following but the image is not uploaded:
StorageReference taskSnapshotStorage = taskSnapshot.getStorage();
Uri downloadUrl = taskSnapshotStorage.getDownloadUrl().getResult();
The images aren't loaded quickly from firebase storage in my app. what might be the problem ? This is the stack overflow post.
It is taking lot of time to load on my screen. This is the problem. How can i fix this ?
at line 202 Uri downloadUrl = taskSnapshot.getDownloadUrl();
showing error: this method should only be accessed from tests or within private scope.
After using this code, no any messages are visible.

Current behavior has double messages when you add a photo message because onpause doesn't clear the adapter, but it does remove the listener
I have searched multiple sites for this error but I'm end up getting solutions like, remove ":15.0.0" or change java to kotlin than use kapt etc, I need a better solution to my problem.
I cannot remove ":15.0.0" as this a dependency give to me
implementation 'com.google.firebase:firebase-database:16.0.1:15.0.0'
I have highlighted the things that need to be concerned.
I am using Android Studio 2.2.3 - after adding FirebaseUI Auth dependencies. i m getting following error

As per ref link i had updated code for "setProviders". but with the latest code my application get crashed with above error.
can someone please help me to solve this issue OR tell me what i am doing wrong?
The above method is deprecated now as well.
Trying to run the app I came across the following problem: The setProviders method cannot be resolved. Instead of the code provided in the example code
setProviders( AuthUI.EMAIL_PROVIDER, AuthUI.GOOGLE_PROVIDER)
we should declare the Providers for email and Google as follows:
setAvailableProviders( Arrays.asList(new AuthUI.IdpConfig.EmailBuilder().build(), new AuthUI.IdpConfig.GoogleBuilder().build()))
on creating an instance of database the app crashed
mFirebaseDatabase = FirebaseDatabase.getInstance();
In MessageAdapter.java file, It is not possible to import com.bumptech.glide.Glide class.
May be it is not exist.
kindly suggest a solution.
From.getCurrentUser(); in this part it doesn't t return any CurrentUser it give me the redline method how can i fix this ???
public void onAuthStateChanged(@nonnull FirebaseAuth firebaseAuth) {
FirebaseUser user= FirebaseAuth_.getCurrentUser();_
if(user!=null){

When I press back button on the Gallery Intent, It exits the app. How do I go to the previous chat screen when pressed back button ? What should be done to this logic ?
// ImagePickerButton shows an image picker to upload a image for a message
mPhotoPickerButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {

}
});
Hola llevo un tiempo buscando como obtener el url https: de Storage pero lo único que encuentro solo es para sacar el gs: Como puedo obtener este url en código de android studio (https://firebasestorage.googleapis.com...................................................................)
I believe solution is
@OverRide
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Task urlTask = taskSnapshot.getStorage().getDownloadUrl();
while (!urlTask.isSuccessful());
Uri downloadUrl = urlTask.getResult();
//rest
}
the 'activateFetched()' method is deprecated; what should I use now?
I can select photo but could not upload the photo to firebase
estou com problema meu codigo whastapp clone esta dando erro Uri url = taskSnapshot.getDownloadUrl(); salva foto banco faribase nao fixa foto perfil whastapp clone

Whenever tried to add
compile 'com.google.firebase:firebase-core:15.0.0'
it gives an error
Gradle 'app' refresh failed
failed to open zip file
Gradle's Dependency cache may be corrupt
This was the error while I'm trying to run my app. It is showing me error here.
error: cannot find symbol variable menu
Can you please help me in solving this. I'm unable to figure out.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
When I performed gradlew build --stacktrace, This was the Stack trace i got.
:app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).
D:\FirebaseApps\WeCare\app\src\main\java\com\pc\wecare\MainActivity.java:120: error: cannot find symbol
inflater.inflate(R.menu.main_menu, menu);
^
symbol: variable menu
location: class R
1 error
:app:compileDebugJavaWithJavac FAILED
First i upgraded my gradle build tools to 3.4.2 then i upgraded my compile sdk to 28 and i'm still getting errors,
Currently i'm getting:
Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:5:5-19:19 to override.
Can someone who has gotten this to work just paste their app gradle file here for me to use. I just cant seem to get this to work.

I think create gist for new version of android will be very helpful for new users.
This is my code.
mPhotoPickerButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.setType("image/*");
i.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
startActivityForResult(Intent.createChooser(i, "Complete action using"), RC_PHOTO_PICKER);
}
});
This is my onAcitivity Method:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_SIGN_IN) {
if (resultCode == RESULT_OK) {
Toast.makeText(MainActivity.this, "Welcome to BCM!", Toast.LENGTH_SHORT).show();
} else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Sign in cancelled", Toast.LENGTH_SHORT).show();
finish();
} else if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
// Get a reference to store file at photos/<FILENAME>
StorageReference photoRef = mPhotosStorageReference.child(selectedImageUri.getLastPathSegment());
//Upload file to Firebase Storage
photoRef.putFile(selectedImageUri)
.addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// When the image has successfully uploaded, we get its download URL
@SuppressWarnings("VisibleForTests")
Uri downloadUrl = taskSnapshot.getDownloadUrl();
// Set the download URL to the message box, so that the user can send it to the database
Message message = new Message(null, userName, downloadUrl.toString());
messagesDatabaseReference.push().setValue(message);
}
});
}
}
}
Please review my code and tell me where I'm going wrong.
I'm running this app on my mobile Device ( Android Nougat - Moto G4) through USB.
My Android Studio is up to date. Further, I have updated repository as suggested and resynced. but receiving the following error in MessageAdapter.java
Error:(41, 13) error: cannot find symbol variable Glide
Error:(12, 26) error: package com.bumptech.glide does not exist
and also receiving Error:(105, 27) error: cannot find symbol variable menu
in MainActivity.java inflater.inflate(R.menu.main_menu, menu);
I'm setting up the firebase project exactly following the instructions. I keep getting the above error on syncing with gradle. Updating gradle version does not help. Idea's are welcome.
On Mrashmallow and Lollipop,this did not work correctly due to permission to access storage not being present in AndroidManifest.
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
