I've made a recipe app, i've been fixing a few issues because i couldn't get the app running but it seems that everytime a fix an error another one shows up, my project can't resolve method dismiss() i don't know what to do, i've made this app accordingly to an Youtube channel but it's giving me lots of issues, i don't know if i missed some code or if it's something else, i've also noticed that there are many things in my Dialog.java that cannot be resolved, such as setDefaultIcon, WindowDecorActionBar, #UnsupportedAppUsage, isDestroyed, setShowHideAnimationEnabled, IdRes among lots of other things, i don't even know where all of that comes from i'm a bit lost here.

When i write the otp manually , then i don't have this issue, main activity opens only one time but when it auto reads the otp and directly sends me to main activity from login (skipping otp screen) then main activity opens two times.

And this is my otp screen activity code.
after login my main activity opens but within 5 seconds my main activity opens again. Can anyone help me out with this issue.
Thanks in advance.
I have tried to solve an issue on my app but I couldn't find a solution. I want the app to upload the images on Firebase Storage after the post is clicked. The problem is that when I click post the images are uploaded as .null and I can't add them as posts on my app here is a photo of Firebase Storage:

I thought that I have to initialize Uri inside onCreate method but nothing changed. What should it be?
I found the solution for anyone else who has the same issue, the solution is that I should have added a ! into this if, like this:
if (!task.isSuccessful()) {
throw task.getException();
}
It has been noticed that the method you are using to retrieve the file mime type doesn't work on some devices. You could try some other alternatives like using apache commonsIO lib or alternatively try this code :
public String getMimeType(Uri uri) {
String mimeType = null;
if (ContentResolver.SCHEME_CONTENT.equals(uri.getScheme())) {
ContentResolver cr = getAppContext().getContentResolver();
mimeType = cr.getType(uri);
} else {
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
.toString());
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
fileExtension.toLowerCase());
}
return mimeType;
}
I am creating app that stores music from device to firebase. I am using Firebase storage, and database, all is working but but when I upload it it shows me progress bar with progress and after that app crashes I found that file is uploaded in storage but not came it database

I think the way you try to upload the song in the database (in Realtime Database I suppose) is wrong. In the method uploadDetailsToDatabase, write:
Declare the reference, in the begining of the class:
DatabaseReference songsDatabase;
Initialize the reference, in onCreate() method, with the path of the song table inside the database:
songsDatabase = FirebaseDatabase.getInstance().getReference("songs");
Add the song object in the realtime database:
Songs songObj = new Songs(songName, songUrl);
DatabaseReference ref = FirebaseDatabase.getInstance().getReference();
songsDatabase.child(songName).setValue(songObj).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()){
Toast.makeText(MainActivity.this,"Song Uploaded",Toast.LENGTH_SHORT).show();
}
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(MainActivity.this, e.getMessage(),Toast.LENGTH_SHORT).show();
}
});
In that way, you create a data(table) in the Realtime Databse, with the name of the song, as the name of this table (songName). Inside this table, you have 2 fields: The song name, and the url of the song.
You may find usefull this answer:
how to resolve java.lang.IllegalStateException: Task is not yet complete Error when uploading image to Firebase storage?
You should avoid using while loop inside a callback listener, instead you can check on the other listener method onComplete() if the upload has been successful or not.
My app uses firebase and it needs to send a verification email to the user after registration before they can login. In my code, the app fails to send the verification email and I found out that the user is always null (while debugging) in line 86/88 of my code. any help would be greaty appreciated.

Thanks a lot #Praveen and #Alex... figured it out, I made a mistake of signing out the user in the else statement [of the if(user.isEmailVerified()) block in the firebaseAuthSetup() method]. probably wouldn't have gotten it if I didn't retrace from the onComplete()
When I log in through facebook, I am supposed to get some data from Facebook such as my email, name and profile picture. However, now I can't get the data anymore after I added these codes
#Override
public void onSuccess(LoginResult loginResult) {
final AccessToken accessToken = loginResult.getAccessToken();
GraphRequestAsyncTask request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject user, GraphResponse graphResponse) {
LoginManager.getInstance().logOut();
}
}).executeAsync();
Toast.makeText(getApplicationContext(), "Login Success with Facebook", Toast.LENGTH_SHORT).show();
startActivity(new Intent(LoginScreen.this, MainActivity.class));
}
I am supposed to get these Facebook datas in this activity
