I have a class that uses an asyntask to store data in a database, everything works fine, until the moment where I want to add a progressdialog to wait for the insertion in the database, I leave my current code, I hope can you help me?

public class RegisterShopPageActivity extends AppCompatActivity {

    EditText nombre, contraseña, email, cumple, comuna;
    String un, pass, db, ip;
    TextView boton;
    FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthListener;
    Connection con;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        getSupportActionBar().hide();
        setContentView(R.layout.activity_register_shop);

        nombre = (EditText) findViewById(R.id.nombreR);
        contraseña = (EditText) findViewById(R.id.passR);
        email = (EditText) findViewById(R.id.mailR);
        cumple = (EditText) findViewById(R.id.cumpleR);
        comuna = (EditText) findViewById(R.id.viveR);
        boton = (TextView) findViewById(R.id.activity_register_shop_submit);
        ip = getResources().getString(R.string.host);
        db = getResources().getString(R.string.db);
        un = getResources().getString(R.string.user);
        pass = getResources().getString(R.string.pass);


        boton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                RegisterShopPageActivity.CheckLogin checkLogin = new RegisterShopPageActivity.CheckLogin();
                checkLogin.execute("");
            }
        });

        mAuthListener = new FirebaseAuth.AuthStateListener() {

In my opinion, I think it's because some method in the doInBackgrounds has something that modifies the activity and makes the context of the application lose.

Try what this tutorial explains

You must pass to asyntask the reference of the activity with WeakReference

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        new MyAsyncTask(this).execute();
    }
    private static class MyAsyncTask extends AsyncTask {

        private WeakReference<MainActivity> mainActivity;    

        public MyAsyncTask(MainActivity mainActivity) {   
            this.mainActivity = new WeakReference<>(mainActivity);            
        }
        @Override
        protected Object doInBackground(Object[] params) {
            return doSomeStuff();
        }
        private Object doSomeStuff() {
            //do something to get result
            return new Object();
        }
        @Override
        protected void onPostExecute(Object object) {
            super.onPostExecute(object);
            if (mainActivity.get() != null){
                //accede a los componentes de mainactivity
            }
        }
    }
}

Another solution is to use observables here the tutorial

It can also be that when the activity is closed and the background task continues and at the end, it does not find the reference of the dialogue:

@Override
public void onDestroy(){
    super.onDestroy();
    if ( progressDialog!=null && progressDialog.isShowing() ){
        progressDialog.cancel();
    }
}

I do it in the following way. I declare the ProgressDialog as an attribute of the main class, in this case within RegisterShopPageActivity. I initialize it and show it in the OnPreExecute method of the Asynktask and I close it in the postExecute, similar to what you do but not the same.

public class RegisterShopPageActivity extends AppCompatActivity {
    ProgressDialog dialog;
    ...

    public class CheckLogin extends AsyncTask<String,String,String> {

        @Override
        protected void onPreExecute() {
            dialog = new ProgressDialog(RegisterShopPageActivity.this);
            dialog.setMessage("Espere...");
            dialog.setIndeterminate(true);  //Las propiedades que quieras
            dialog.setCancelable(false);    //Las propiedades que quieras
            dialog.show();
        }

        @Override
        protected String doInBackground(String... urls) {...}

        @Override
        protected void onPostExecute(String result) {
            ...
            dialog.dismiss();
        }

    }
}

If you do this, the ProgressDialog is closed once you have finished the code you type in the method onPostExecute
