When I tried to run the program and upload the image to the firebase, it doesn't success... Anyone can help me.. It looks like the Task is not success but I have do some research and still can't solve it.
val fileRef :StorageReference = storageProfilePicRef!!.child(firebaseUser!!.uid + ".jpg")
var uploadTask: StorageTask<*>
uploadTask = fileRef.putFile(imageUri!!)
uploadTask.continueWithTask(Continuation <UploadTask.TaskSnapshot, Task<Uri>>{ task ->
if(!task.isSuccessful){
task.exception?.let {
throw it
progressDialog.dismiss()
}
}
return#Continuation fileRef.downloadUrl
//not able to download the image url successfully so cannot go in task.isSuccessful
}).addOnCompleteListener(OnCompleteListener<Uri>{ task ->
if (task.isSuccessful){
Toast.makeText(this, "123.", Toast.LENGTH_LONG).show()
val downloadUrl = task.result
myUrl = downloadUrl.toString()
val ref = FirebaseDatabase.getInstance().reference.child("Users")
val userMap = HashMap<String, Any>()
userMap["fullname"] = full_name_profile_frag.text.toString().lowercase()
userMap["username"] = username_profile_frag.text.toString().lowercase()
userMap["bio"] = bio_profile_frag.text.toString().lowercase()
userMap["image"] = myUrl
ref.child(firebaseUser.uid).updateChildren(userMap)
Toast.makeText(this, "Account Information has been updated successfully", Toast.LENGTH_LONG).show()
val intent = Intent(this#AccountSettingsActivity, MainActivity::class.java)
startActivity(intent)
finish()
progressDialog.dismiss()
}
else{
Toast.makeText(this, task.toString(), Toast.LENGTH_LONG).show()
progressDialog.dismiss()

I'm using Kotlin, Android Studio and Jetpack Compose
What I want to do:
After the button click, I would want to register the user using google authentication and firebase
What I've tried to do:
I've tried to follow Firebase Auth Documentation, but it's really hard to understand as it often sends me back to the Google Documentation, which isn't helpful either in the case of Jetpack Compose.
I couldn't find any up to date videos or guides explaining this implementation. It would be awesome if someone could explain how to start with it.
val context = LocalContext.current
val token = stringResource(R.string.default_web_client_id)
val launcherNav = rememberLauncherForActivityResult(

val launcher = rememberLauncherForActivityResult(
contract = ActivityResultContracts.StartActivityForResult(),
) {
val task =
try {
val account = GoogleSignIn.getSignedInAccountFromIntent(it.data)

val credential = GoogleAuthProvider.getCredential(account.idToken!!, null)
FirebaseAuth.getInstance().signInWithCredential(credential)

I am trying to get the user uid after creating an account, so I can create a document on Firestore with the uid as document id. The problem is that I get only null, everything is working fine and I'm able to sign the user and receive the code but the uid is always null.
I know I'm accessing the uid before it's initialized because it takes time to restore the authentication state when the app starts so any idea how to wait for it until it's initialized?
First of all, if the data entered is correct then we call login() function, then we send the verification code, when the code is sent inside the onCodeSent(), the method we call uploadSelectedImageToFirebaseStorage() to upload the user image then we call saveUserToDatabase() function, and here is the problem. Inside the saveUserToDatabase() function, the UID is always null no matter what I tried, am I missing something?

I need to login users with Google Sign On onto Firebase. But since I need to use the Calendar API, I have to do a custom login (and not the one provided through Firebase on default), as I need the Oauth refresh token - which is not provided by Firebase. I have looked at the docs but none seem to work, I am using the below code as of now... can anybody suggest how do I use the token obtained from Google to login/register with Firebase?

My method of checking if the user exists was incorrect with the currect process being to put the check on Datasnapshot exits or not. If exists then login else register.
I have this code where am supposed to upload an image and get the downloaded url but whenever i do that I get this error
my url is String url;. So please why is this not working as it is supposed to
PS
I checked other website to learn how to properly upload but it keeps giving me an error or is there a better way to do this.
My code image
uploadTask.whenComplete(()async{
url = await refs.getDownLoadURL();
....
});
Since it returns a Future you need to wait for it to be accessed
Example :
Future<String> createFolder(String folderName) async {
final dir = Directory(
'${(io.Platform.isAndroid ? await getExternalStorageDirectory() //FOR ANDROID
: await getApplicationSupportDirectory() //FOR IOS
)!.path}/$folderName');
var status = await Permission.storage.status;
if (!status.isGranted) {
await Permission.storage.request();
}
if ((await dir.exists())) {
return dir.path;
} else {
dir.create();
return dir.path;
}
}
Future<String> getIslamiSahittoBookFilePath(String savename) async {
Future<String> s = createFolder("Islami_Sahitto");
String filePath = await s;
Map<Permission, PermissionStatus> statuses = await [
Permission.storage,
//add more permission to request here.
].request();
io.File? f = null;
if (statuses[Permission.storage]!.isGranted) {
Directory? dir = await DownloadsPath.downloadsDirectory();
if (dir != null) {
String savePath = "${dir.path}/$filePath/$savename";
f = new io.File(savePath);
if (await f.exists()) {}
}
}
return f.toString();
}
Now this block You can use AnyWhere : Future String, to String :
bool isPreviousDownloaded = false;
String previousFilePath = "null";
getIslamiSahittoBookFilePath(fileNameToDownload).then((value) {
if (value != null) {
setState(() {
isPreviousDownloaded = true;
previousFilePath = value;
});
}
});
This is my first time setting auth rules using Firestore, and I can't seem to figure out how to fix this problem. I apologize if this is a repeat, however I cannot find what I'm missing. When I logout of my app, I get a Permission Denied with the below code, even when I return the listener if there is an error. How can I prevent this from happening?
db.collection("chats").whereEqualTo(currentUser, true)
.addSnapshotListener {snapshot, error ->
if (error != null) {
Log.e("ChatsFragment", "Error getting chats. Error: $error")
return#addSnapshotListener
}
if (snapshot!!.isEmpty) {
noMsgs.visibility = View.VISIBLE
} else {
noMsgs.visibility = View.GONE
}
}
Here is my Logout just in case.
AuthUI.getInstance().signOut(this)
.addOnCompleteListener { task ->
if (task.isSuccessful) {
val intent = Intent(this, CheckUser::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
finish()
handler.postDelayed({
startActivity(intent)
Toast.makeText(this, "You have been logged out.", Toast.LENGTH_SHORT).show()
}, 1000)
} else {
val intent = Intent(this, CheckUser::class.java)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
finish()
startActivity(intent)
Log.e("LogoutActivity", "Error logging out. ${task.exception?.message.toString()}")
}
}
