Lol it's now working. I forgot to add the code for the mAuth and mLoadingBar in the java. Thanks Alex Mamo for reminding me of the logcat
mAuth = FirebaseAuth.getInstance();
mLoadingBar = new ProgressDialog(this);

Android app works on emulator, installs on phone, and crashes on device [duplicate]

This question already has answers here:

Unfortunately MyApp has stopped. How can I solve this?
(23 answers)
Closed 2 years ago.
This is a weird and I'm not sure what I have done wrong. The app installs perfectly fine on my Samsung J7 but as soon as I move from the MainActivity to the ScheduleActivity it crashes. On the other hand my fiance who lives in the the Netherlands has a Huawei Mate 20 pro and she can use it fine. I've sent her many iterations and she just updates the app and uses it. I built this app with mvc architecture so there are no calls to the database or model. I'll include the layout, some images, and the java code. If I can add anything else please let me know. Thank you for your help solving this.
MainActvity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button scheduleButton = findViewById(R.id.schedule_button);
scheduleButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MainActivity.this, ScheduleActivity.class);
startActivity(intent);
}
});
}
activity_main.xml:

How the main layout looks:
Also here is a visual on the apps structure:
All I am doing is moving from the main package to the ui package and accessing the ScheduleActvity which has this code:
public class ScheduleActivity extends AppCompatActivity implements View.OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_schedule);
Button mondayButton = findViewById(R.id.monday_button);
Button tuesdayButton = findViewById(R.id.tuesday_button);
Button wednesdayButton = findViewById(R.id.wednesday_button);
Button thursdayButton = findViewById(R.id.thursday_button);
Button fridayButton = findViewById(R.id.friday_button);
Button saturdayButton = findViewById(R.id.saturday_button);
Button sundayButton = findViewById(R.id.sunday_button);
mondayButton.setOnClickListener(this);
tuesdayButton.setOnClickListener(this);
wednesdayButton.setOnClickListener(this);
thursdayButton.setOnClickListener(this);
fridayButton.setOnClickListener(this);
saturdayButton.setOnClickListener(this);
sundayButton.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.monday_button:
Intent monday_intent = new Intent(ScheduleActivity.this, MondayActivity.class);
startActivity(monday_intent);
break;
case R.id.tuesday_button:
Intent tuesday_intent = new Intent(ScheduleActivity.this, TuesdayActivity.class);
startActivity(tuesday_intent);
break;
case R.id.wednesday_button:
Intent wednesday_intent = new Intent(ScheduleActivity.this, WednesdayActivity.class);
startActivity(wednesday_intent);
break;
case R.id.thursday_button:
Intent thursday_intent = new Intent(ScheduleActivity.this, ThursdayActivity.class);
startActivity(thursday_intent);
break;
case R.id.friday_button:
Intent friday_intent = new Intent(ScheduleActivity.this, FridayActivity.class);
startActivity(friday_intent);
break;
case R.id.saturday_button:
Intent saturday_intent = new Intent(ScheduleActivity.this, SaturdayActivity.class);
startActivity(saturday_intent);
case R.id.sunday_button:
Intent sunday_intent = new Intent(ScheduleActivity.this, SundayActivity.class);
startActivity(sunday_intent);
}
}
This is the respective layout file activity_schedule which has these buttons:
<Button
android:id="#+id/thursday_button"
style="?android:attr/borderlessButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="24dp"
android:layout_marginTop="8dp"
android:background="#drawable/button_state"
android:text="#string/thursday"
android:textColor="#drawable/button_text_color"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/monday_button" />
And looks like this (I so badly wish I could easily add a drop shadow to the image):
The buttons lead to a given day you want to know more about such as ThursdayActivity or MondayActvity (I'm still not sure on the ui but I'm getting closer):
All of the daysoftheweek activities look the same as this and this ThursdayActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_thursday);
//groupsArrayList = new ArrayList<>(); --debug
DatabaseHandler db = new DatabaseHandler(ThursdayActivity.this);
/* Uncomment and insert the group data*/
db.thursdayAddGroup(new Groups("Thursday","Daily reflection|Just for Today","9:00 AM","10:00 AM"));
db.thursdayAddGroup(new Groups("Thursday","12 Step|Sponsorship","12:00 PM","1:00 PM"));
db.thursdayAddGroup(new Groups("Thursday","HVN (Hearing voices network)","1:15 PM","2:45 PM"));
db.thursdayAddGroup(new Groups("Thursday","WRAP","3:00 PM","4:00 PM"));
TextView thursdayGroupNameOne = findViewById(R.id.thursday_group_name_one);
TextView thursdayGroupStartTimeOne = findViewById(R.id.thursday_group_start_time_one);
TextView thursdayGroupEndTimeOne = findViewById(R.id.thursday_group_end_time_one);
/* Explicitly indexing the database objects */
List<Groups> groupsList = db.getAllThursdayGroups();
thursdayGroupNameOne.setText(groupsList.get(0).getGroupDay());
thursdayGroupStartTimeOne.setText(groupsList.get(0).getGroupStartTime()); thursdayGroupEndTimeOne.setText(groupsList.get(0).getGroupEndTime());
All daysoftheweek layouts have a cardview that contain the textviews to get and display the data from the database set in the given activity such as this actvity_thursday.xml:

I hope this isn't too much and I did remove all unnecessary code so as not to throw the whole thing at you. Thanks truly, Wes.

Retrieve Data from multiple documents from Firestore Database

Unable to fetch a value from the Firestore database. Trying to retrieve the value of the mobile number as and when the value of flat and block matches the entry in the database. Below is the code I am using. I have also attached the issues that are registered in LogCat file. Please check and help.
public class Test extends AppCompatActivity {
Button btn;
private FirebaseFirestore firestore;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
firestore = FirebaseFirestore.getInstance();
btn = (Button) findViewById(R.id.button3);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getmobile();
//makecall();
}
});
}
private void makecall(){
Intent intent = new Intent(Intent.ACTION_CALL_BUTTON);
intent.setData(Uri.parse("tel:9890910640"));
startActivity(intent);
}
private void getmobile() {
firestore.collection("users").get().addOnSuccessListener(new OnSuccessListener<QuerySnapshot>() {
#Override
public void onSuccess(QuerySnapshot documentSnapshots) {
String a = "101";
String b = "F1A";
for(DocumentSnapshot document: documentSnapshots){
if(document.getString("flat")==a&&document.getString("block")==b){
String mobilefromdatabase = document.get("mobile").toString();
Toast.makeText(Test.this, "mobile" + mobilefromdatabase, Toast.LENGTH_LONG).show();
break;
}
}
}
});
}
}

First of all, String comparison in Java, should not be performed using == operator, as it will always compare the address of the objects from the memory and not the actual values. String comparison should be done using equals() method.
Moreover, if you need an AND operation, you should not get all documents that exist within the users collection and make the comparison on the client. For that, you should use a query that looks exactly like this:
String a = "101";
String b = "F1A";
FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
CollectionReference usersRef = rootRef.collection("users");
Query query = usersRef.whereEqualTo("flat", a).whereEqualTo("block", b);
query.get().addOnSuccessListener(/* ... */);
In this way, you are going to get only the documents where the flat property holds the value of 101 AND the value of block holds F1A. As I think that only one apartment has that constraint, you'll be billed with only one read operation.

Logcat Displays Various Types of Errors for The SQLite Database I Created for My Android App

I'm trying to build and an Android app and managed to get through the main purpose of it. However, I'm severely stuck in successfully implementing an SQLite database to have users login if they already have an account off the SQLite database OR create and register for an account.
The relevant classes and XML files for these instructions are correct in my perspective but I believe there's something wrong with my SQLite Query or something wrong when I'd try to look into the Logcat and check for the the registered information from the app user and would display numerous of errors that I find too difficult to debug at this rate.
I will attach the relevant classes, XML files, and what it says at Logcat. Hopefully this way, I can receive the help I'd need as this is severely stopping me from even entering to the main purpose of the app. Your help would be very appreciated. Thank You.

The insert into table reg_info isn't working because of
no column named user_password
, as per :-
table reg_info has no column named user_password (code 1): , while compiling: INSERT INTO reg_info(user_password,user_name) VALUES (?,?)
This is likely due to the table having been modified in your table create SQL (user_password column added at a guess), but that hasn't been applied due to how the onCreate method is invoked.
That is the onCreate method is invoked once when the database itself is created (unless invoked elsewhere), it is not run every time the App is run.
The quickest fix is to either :-
Delete the App's data from settings/Apps or
Uninstall the App
and to then rerun the App.
Noting that this deletes the database and thus any data stored in the database.
If you need to preserve data then you would need to run the SQL ALTER TABLE reg_info ADD COLUMN user_password TEXT at an appropriate place within the code.

esp8266 android connection via telnet

Ive been trying from a very long time to send a string from android app to esp8266 through Telnet. I wish to see the output on serial monitor of arduino IDE.I have used the code from send string to esp8266 via android using telnet
Here are the logs that Im getting on running my android code on connecting connect and send button.

1. I am unable to resolve this ACTION_DOWN statement
2. Also Id like to know what `Buffer Count from app info with ::-1 && -1 for :: com.example.manveenkaur.optimized from View :: -1 DBQ Enabled ::false false means
3. Further on clicking disconnect it shows me the following :-

One question upfront: Are you using SoftwareSerial or HardwareSerial to talk to the ESP8266? Using SoftwareSerial is not going to make you happy.
