How to make Bottom Sheet Dialog that shows one time only

I want to create a Bottom Sheet Dialog. It looks like the image below
enter image description here
public class MainActivity extends AppCompatActivity {
//this is Button that open dialog
private Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.nextBtn);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDialogTheme);
View bottomSheetView = LayoutInflater.from(getApplicationContext())
.inflate(R.layout.layout_bottom_sheet, (LinearLayout) findViewById(R.id.bottomSheetContainer));
bottomSheetDialog.setContentView(bottomSheetView);
bottomSheetView.findViewById(R.id.doNotAgree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
System.exit(0);
}
});
bottomSheetView.findViewById(R.id.agree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(MainActivity.this, Activity2.class));
finish();
}
});
}
});
}
}
I have tried many methods such as SharedPreferences. But it not working

SharedPreferences preference = getSharedPreferences("mPreference", MODE_PRIVATE);
boolean isUserAgreed = preference.getBoolean("isUserAgreed", false);
if (!isUserAgreed){
// show bottomSheetDialog
} else {
startActivity(new Intent(MainActivity.this, Activity2.class));
finish();
}
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDialogTheme);
View bottomSheetView = LayoutInflater.from(getApplicationContext())
.inflate(R.layout.layout_bottom_sheet, (LinearLayout) findViewById(R.id.bottomSheetContainer));
bottomSheetDialog.setContentView(bottomSheetView);
bottomSheetView.findViewById(R.id.doNotAgree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
System.exit(0);
}
});
bottomSheetView.findViewById(R.id.agree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
SharedPreferences.Editor editor = getSharedPreferences("mPreference", MODE_PRIVATE).edit();
editor.putBoolean("isUserAgreed", true);
editor.apply();
startActivity(new Intent(MainActivity.this, Activity2.class));
finish();
}
});
}
});

can someone help me with a warning a resource failed to call close

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.
here is the code for MainActivity
public class MainActivity extends AppCompatActivity {
TextInputEditText textEmail, textPassword;
ProgressBar progressBar;
TextView forgotPassword;

Firebase signout is not leading to the correct activity

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!
private void signOut() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Signout")
.setMessage("Do you really want to sign out?")
.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
}).setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Common.selectedFood = null;
Common.categorySelected = null;
Common.currentUser = null;
FirebaseAuth.getInstance().signOut();
startActivity(new Intent(HomeActivity.this, LoginActivity.class));
finish();
}
});
AlertDialog dialog = builder.create();
dialog.show();
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(Color.BLACK);
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(Color.BLACK);

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();
};

createDialog for onBackPressed but my app showing error close app

I have created a new layout name dialog_exit for onBackPressed but when I install and open, my application can not open and showing error close app
Please review my whole code and guide me how can I solve this problem
Here is my main activity code
public class MainActivity extends AppCompatActivity {
public Dialog mDialog;
public Button mDialogyes, mDialogno;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
createDialog();
}
private void createDialog() {
mDialog = new Dialog(this);
mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
mDialog.setContentView(R.layout.dialog_exit);
mDialog.setCanceledOnTouchOutside(true);
mDialog.setCancelable(true);
mDialogyes = (Button) findViewById(R.id.yes);
mDialogno = (Button) findViewById(R.id.no);
mDialogyes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setFlags(intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
finish();
System.exit(0);
mDialogno.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mDialog.dismiss();
}
});
}
});
}
#Override
public void onBackPressed() {
mDialog.show();
}
}
Here is my layout code as screenshot because
stackoverflow not allow me to add more code that why sharing image

Updated code of createDialog function
private void createDialog() {
mDialog = new Dialog(this);
mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
mDialog.setContentView(R.layout.dialog_exit);
mDialog.setCanceledOnTouchOutside(true);
mDialog.setCancelable(true);
mDialogyes = (Button) mDialog.findViewById(R.id.yes);
mDialogno = (Button) mDialog.findViewById(R.id.no);
mDialogyes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setFlags(intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
finish();
System.exit(0);
}
});
mDialogno.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mDialog.dismiss();
}
});
}

try this code
mDialogyes = (Button)mDialogyes. findViewById(R.id.yes);
mDialogno = (Button)mDialogyes. findViewById(R.id.no);
mDialogyes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setFlags(intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
finish();
System.exit(0);
}
});
mDialogno.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mDialog.dismiss();
}
});

You have to do like this
mDialogyes = (Button) mDialog.findViewById(R.id.yes);
mDialogno = (Button) mDialog.findViewById(R.id.no);

"Resource was acquired but never released" error with parse.com

A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.
I am trying to log in and sign up using my application and found the above error.
Following is my code of main activity.
public class MainActivity extends AppCompatActivity {
#Override
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);
