Android Activity is restarting multiple times in a loop in android studio

Email login activity allows user to log in to his account. here , after the user is logged in , he will be sent to main activity using the main activity intent. here as soon as the user is logged in to the account , he is sent to main activity , and the main activity is restating continously . the screen recording video is uploaded in the link mentioned "https://drive.google.com/file/d/1QRy2J1YkMRJdbjgMIIl-T58DsGnamtGX/view?usp=sharing"

Mistake is here that you called finish(); before calling startActivity(MainIntent);. Use camelCaseinstade of Capital case in defining variable.
Make changes in your emailloginActivity as below
// changed from MainIntent to mIntent.
private void SendUserToMain() {
String userName = mAuth.getCurrentUser().getUid();
Intent mIntent = new Intent(emailloginActivity.this, MainActivity.class);
mIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
mIntent.putExtra("mUserID" , userName );
startActivity(mIntent);
finish();

Create photo with Bitmap

I'm working on an app that uploads an image to the firebase database from the gallery and camera.
From the gallery it works, but from the camera need create that image when I take it. All tutorial I found have mistakes and I don't know how do it.
private Button btnCamera, btnGallery, btnList;
private StorageReference storage; //referencia para usar Storage
private static final int GALLERY_INTENT = 1;
private static final int CAMERA_REQUEST_CODE = 2;
private static final String AUTHORITY=BuildConfig.APPLICATION_ID+".provider";
private ProgressDialog progressDialog;
private File file = null;
ImageView imgView = null;
Calendar c = Calendar.getInstance();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fecha = df.format(c.getTime());
private EditText TextNombre;
private EditText TextApellidos;
private TextView TextSalida;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_select_method);
storage = FirebaseStorage.getInstance().getReference();
TextNombre = (EditText) findViewById(R.id.textN);
TextApellidos = (EditText) findViewById(R.id.textA);
TextSalida = (TextView) findViewById(R.id.salida);
progressDialog = new ProgressDialog(this);
btnCamera = (Button) findViewById(R.id.buttonCamera);
btnGallery = (Button) findViewById(R.id.buttonGallery);
btnList = (Button) findViewById(R.id.buttonList);
String dato = getIntent().getStringExtra("dato");
TextSalida.setText(dato);
This is the method to take a picture with the camera:
//-------------METODO TOMAR FOTO CON LA CAMARA-------------
btnCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
/*Intent btnImage = new Intent(SelectMethod.this, TakePhoto.class);
startActivity(btnImage);*/
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, CAMERA_REQUEST_CODE);
}
}
});
And this with gallery:
//-------------METODO SELECCIONAR IMAGEN DESDE GALERIA-------------
btnGallery.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent (Intent.ACTION_PICK); //selecciona una imagen de la galería
intent.setType("image/*"); //permitimos todas las extensiones de imagenes
startActivityForResult(intent,GALLERY_INTENT);
}
});
}
OnActivityResult for two methods:
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case GALLERY_INTENT:
if (requestCode == GALLERY_INTENT && resultCode == RESULT_OK) { //verificamos que la imagen se obtuvo de manera correcta
Uri uri = data.getData();
StorageReference filePath = storage.child(getIntent().getStringExtra("dato")).child(fecha + " " + uri.getLastPathSegment());
filePath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Toast.makeText(SelectMethod.this, "La imagen se subió correctamente.", Toast.LENGTH_SHORT).show();
}
});
}
break;
case CAMERA_REQUEST_CODE:
if(requestCode == CAMERA_REQUEST_CODE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap bitmap = (Bitmap) extras.get("data");
imgView.setImageBitmap(bitmap);
}
break;
}
}
}

Item duplicated in RecyclerView after application call onStart

Every time the application is destroyed and opened again, by another mean every time the method "onStart" is called, every new item added two times.
And when I close it and open it again, every new item will be repeated three times , and so on...
Here is the code of the activity :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chat);
IntializeControllers();
if (getIntent().getExtras() != null && getIntent().getStringExtra("userID" ) != null&& getIntent().getStringExtra("userName") != null&& getIntent().getStringExtra("userImage") != null){
messageReceiverID = getIntent().getExtras().get("userID").toString();
if (messageReceiverID.equals(auth.getCurrentUser().getUid())){
Toast.makeText(this, "يرجى التأكد من إعدادات تسجيل الدخول", Toast.LENGTH_SHORT).show();
finish();
}
messageReceiverName = getIntent().getExtras().get("userName").toString();

I appreciate your help as I can't figure out the problem. Please note that a lot of functions have been removed for readability.

To resolve your issue, clear adap zter while loading new data, so duplicacy can be removed and update new data. This issue occur due to multiple call on Android Lifecycle method in various state like
onResume - Called multiple times. So avoid initalization in here
onStart - is called whenever application is come from background to foreground or visible state
// When adding new data
adapter.addAll(data);
adapter.notifyDataSetChanged();
// when updating data again in onResume or onStart
adapter.clear();// clear old data from list
adapter.addAll(data);
adapter.notifyDataSetChanged();
//Inside adapter
//Adding item
void addAll(List<Data> data){
list.addAll(data);
}
//For clearing list
void clear(){
list.clear();
// To update list automatically add below line
//notifyDataSetChanged();
}

The authentification firebase remember me after logout

I enter my main activity, inside the MainActivity I have registration, after the registartion accure I want to log out from firebase so that he doesn't remember me.
Because when I retured to the MainActivity after the signout he still remembers the previous user when I register as a new user. This occurs only after logging and logout immediately. Btw, if I run the app its working fine. The problem is only when I signout and then going to RegistrationActivity to register another user.
Here is the MainActivity code:

startActivity(new Intent(getContext(), LoginActivity.class));
}
});
}
