I tried to integrate an AlertDialog into my app via which the customer can log out. When I call up the dialog, it just works as it should be. However, if I press "log out" Iam not forwarded to the LoginActivity as requested. Instead, my dialog simply closes and the HomeActivity is reloaded.
What am I doing wrong here?
Greetings and thanks!

As I said in the comments.
You are starting the LoginActivity before the Firebase actually logout the user. Try to add a FirebaseAuth.AuthStateListener and just start the LoginActivity when the listener is trigged.
I added the following code to my LoginActivity OnCreate;
listener = firebaseAuth -> {
Dexter.withActivity(this)
.withPermissions(
Arrays.asList(
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA)
)
.withListener(new MultiplePermissionsListener() {
#Override
public void onPermissionsChecked(MultiplePermissionsReport report) {
if(report.areAllPermissionsGranted())
{
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
} else {
}
}
else
Toast.makeText(LoginActivity.this, "You must accept all permissions", Toast.LENGTH_SHORT).show();
}
#Override
public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
}
}).check();
};

I am getting an error 'Failed to instrument: android/app/ResourcesManager'. This is probably the reason when I open the app it crashes immediately. There are no other errors but this error in the logcat.
The warning appears only AFTER the first time I use the emulator.
I download the avd again and open it for the first time the code works perfectly
It would mean the world to me if someone can help me fix this issue.

Introduced some code that makes my PostAdapter return the wrong postid when I Log it, and the post isn't being liked... I am not sure how to fix it. App doesn't crash or anything, but I am unsure how to fix it.
Post has three ImageViews, and when they are clicked on they change color. That before was happening as it is supposed to, but now it isn't working... App doesn't crash, like I said, but when I Log it, I get back the wrong postid.
Likes aren't being saved to correct posts, and comments aren't being recorded.
Can anyone advise me on why this is happening?

The problem is at
public Post post;
Whenever a row is rendered, its value is assigned to this one. When the user taps on another row, the adapter still uses this post to get the id.
Just simply get rid of the post and use position to access the item the user just tapped on.
This is because you are using setting a click listener in onbind which will overwrite the previous click listener so the post in that click listener will never be synced up correctly. You should move your click listeners to the viewholder instead. Or an easy fix is to use getItem(viewholder.adapterPosition) in the click listener

I think the problem is in the LoginActivity, because when I wrote some code in it, the problem arose
Once the user is logged in, onStart will send the user to mainActivity
You need to create a logOut button in MainActivity, So it will not skip login page
you can also clear data of the app from the devices to make the currentUser == null
for logout
FirebaseAuth auth = FirebaseAuth.getInstance()
auth.logOut();
I am developing an android application on Android Studio With Firebase and i am having the following error:
[unchecked] unchecked cast
required: OnSuccessListener
found: Uri
When I click to Show where is the problem it takes me to this code:
private void uploadImageToFirebaseStorage() {
final StorageReference profileImageRef =
FirebaseStorage.getInstance().getReference("profilepics/"+System.currentTimeMillis()+".jpg");
if(uriProfileImage!=null){
profileImageRef.putFile(uriProfileImage)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
profileImageRef.getDownloadUrl().addOnSuccessListener((OnSuccessListener<? super Uri>) uriProfileImage);
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(Profile.this,e.getMessage(),Toast.LENGTH_SHORT).show();

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (ParseAnonymousUtils.isLinked(ParseUser.getCurrentUser())) {
Intent intent = new Intent(MainActivity.this, LoginSignupActivity.class);
startActivity(intent);
finish();
} else {
ParseUser currentUser = ParseUser.getCurrentUser();
if (currentUser != null) {
Intent intent = new Intent(MainActivity.this, Welcome.class);
startActivity(intent);
finish();
} else {
Intent intent = new Intent(MainActivity.this, LoginSignupActivity.class);
startActivity(intent);
finish();
}
}
}
}
Following is my code of LoginSigupActivity
