When I try to save a ParseObject in my Android app it does not seem to be saving to the Dashboard. There seems to be no error's showing. Here's my code.
N.B: The code is nested within protected void onCreate(Bundle savedInstanceState)
continue_reg.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
firstNameTxt = first_name.getText().toString();
lastNameTxt = last_name.getText().toString();
if (firstNameTxt.equals("") && lastNameTxt.equals("")) {
Toast.makeText(getApplicationContext(), "Please complete all fields", Toast.LENGTH_LONG).show();
} else {
ParseObject patientInfo = new ParseObject("PatientInformation");
patientInfo.put("firstName", firstNameTxt);
patientInfo.put("lastName", lastNameTxt);
patientInfo.saveInBackground();
Toast.makeText(getApplicationContext(), "Complete", Toast.LENGTH_LONG).show();
}
}
});
Try to use the SaveCallback(), so you can see if any error appears.
patientInfo.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
// No error, the object was saved
Toast.makeText(getApplicationContext(), "Complete", Toast.LENGTH_LONG).show();
} else {
// Error saving object, print the logs
e.printStackTrace();
}
}
});

I am trying to add some users in my real time firebase data base, I want to check that by email address which is an User attribute, the problem is that it is adding duplicates. I have an button To add in my database
DAOUser daoUser = new DAOUser();//database accessObject
registerAccountButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (emailField.getText().toString().equals("") || passwordField.getText().toString().equals("") || repeatPasswordField.getText().toString().equals("")) {
Toast.makeText(getApplicationContext(), "Please complete all fields!", Toast.LENGTH_SHORT).show();
} else if (!Objects.equals(passwordField.getText().toString(), repeatPasswordField.getText().toString())) {
Toast.makeText(getApplicationContext(), "Passwords does not match!", Toast.LENGTH_SHORT).show();
} else {
addUser(daoUser, emailField.getText().toString(), passwordField.getText().toString());
}
}
});
The method to add in database:
public void addUser(DAOUser daoUser, String inputMail, String inputPassword) {
daoUser.getDatabaseReference().child("User").orderByChild("email").equalTo(inputMail).addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot snapshot) {
if (snapshot.exists()) {
Toast.makeText(getApplicationContext(), "User already exists!", Toast.LENGTH_SHORT).show();
} else {
User newUser = new User(inputMail, inputPassword, false);
try {
daoUser.add(newUser).addOnSuccessListener(suc -> {
Toast.makeText(getApplicationContext(), "Successfully registered user!", Toast.LENGTH_SHORT).show();
}).addOnFailureListener(er -> {
Toast.makeText(getApplicationContext(), "Unable to register user!", Toast.LENGTH_SHORT).show();
});
} catch (UserIsNullException e) {
e.printStackTrace();
System.out.println("User is null");
}
}
}
#Override
public void onCancelled(#NonNull DatabaseError error) {
Toast.makeText(getApplicationContext(), "User DataBase error !", Toast.LENGTH_SHORT).show();
}
});
}
The database looks like this:
Currently i'm implementing the in app update feature from android. I'm using the immediate update method, the problem that I'm facing is that when the UI prompting the user to update shows and the user does not click the update button instead they click the cross button. The UI for the app update just closes and user can continue using the app.
What I want is that when user click the cross button the app immediately closes, until user updates the app then they can use the app as usual. I also uses the java code for the android development.

The image I borrowed from google, on the left image as can be seen there is a cross button on top right user can click to close the update process
The most important point I will emphasize is that you should not force users to update the app until it is absolutely necessary (like some security issues etc). Forcing updates to users is considered a very bad user experience.
To the question you asked, you have the answer in your question itself. If you check the code you have something like this in your onActivityResult method-
if (requestCode == RC_APP_UPDATE) {
//when user clicks update button
if (resultCode == RESULT_OK) {
Toast.makeText(LoginActivity.this, "App download starts...", Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
//if you want to request the update again just call checkUpdate()
Toast.makeText(LoginActivity.this, "App download canceled.", Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_IN_APP_UPDATE_FAILED) {
Toast.makeText(LoginActivity.this, "App download failed.", Toast.LENGTH_LONG).show();
}
}
In case when the user cancels resultCode == RESULT_CANCELED or the update fails resultCode == RESULT_IN_APP_UPDATE_FAILED, you can take whatever action you want. You can finish the activity or whatever is suitable in your situation.
I have a problem with the Android MediaPlayer. As soon as a new sound file is clicked by user input, the old one does not stop, so all audio files overlap.
I already tried common methods like MediaPlayer.stop(); and
MediaPlayer.release();
These methods always result in an app crash, although they are called in the correct order
public void Abspielen(String Datei) {
try {
AndreasPlayer = MediaPlayer.create(MainActivity.this, getResources().getIdentifier(Datei, "raw", getPackageName()));
AndreasPlayer.start();
} catch (Exception e) {
Toast.makeText(MainActivity.this, e.toString(), Toast.LENGTH_LONG).show();
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Abspielen("filename");
}
I worked out the following solution:
public void Abspielen(String Datei) {
try {
stopKnopf = findViewById(R.id.fab2);
stopKnopf.show();
try {
if (AndreasPlayer.isPlaying()) {
AndreasPlayer.reset();
}
} catch (Exception ex) {
}
AndreasPlayer = MediaPlayer.create(MainActivity.this, getResources().getIdentifier(Datei, "raw", getPackageName()));
AndreasPlayer.start();
stopKnopf.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
AndreasPlayer.reset();
stopKnopf.hide();
}
});
AndreasPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
AndreasPlayer.reset();
stopKnopf.hide();
}
});
} catch (Exception e) {
Toast.makeText(MainActivity.this, e.toString(), Toast.LENGTH_LONG).show();
}
}
saveUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final ParseUser user = new ParseUser();
try {
user.setUsername("12345");
user.setPassword("1234");
} catch(Exception e){
e.getMessage();
}
user.signUpInBackground(new SignUpCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
// Sign-up successful!
Toast.makeText(getApplicationContext(),"Done",Toast.LENGTH_LONG).show();
} else {
// Failed
AlertDialog.Builder builder = new AlertDialog.Builder(SignupActivity.this);
builder.setMessage(e.getMessage())
.setTitle("Oops try again!!!")
.setPositiveButton(android.R.string.ok, null);
AlertDialog dialog = builder.create();
dialog.show();
// Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
}
});
}
});
bad json response: org.json.JSONException: Value invalid of type java.lang.String cannot be converted to JSONObject
Remove final before ParseUser - since final variables are supposed to be immutable it should be like that:
ParseUser user = new ParseUser();
i had created invite users to the app using Facebook in Android, for this used Facebook SDK and added the code given by so peoples, here are my codes
final ImageView facebook1 = (ImageView) findViewById(R.id.facebook1);
facebook1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
// Perform action on click
Facebook facebook1 = new Facebook("APP_ID");
Bundle paramsOut = new Bundle(), paramsIn = this.getIntent().getExtras();
paramsOut.putString("message", paramsIn.getString("message"));
Singlemenuitem.this.mFacebook.dialog(this, "apprequests", paramsOut, new InviteListener(this));
mFacebook.dialog(Singlemenuitem.this, "apprequests", params, new DialogListener() {
public void onComplete(Bundle values) {
final String returnId = values.getString("request");
if (returnId != null) {
Toast.makeText(getApplicationContext(),
"Request sent " + returnId,
Toast.LENGTH_SHORT).show();
}
}
public void onFacebookError(FacebookError error) {}
public void onError(DialogError e) {}
public void onCancel() {}
});
}
but in the place of "InviteListener" getting an error to create class, if the class is created then also getting error. any guidance pls?
Bundle iviteBundleparams = new Bundle();
iviteBundleparams.putString("message",
"invite message");
//TODO:// if you have friend id then you can pass friend id and the request will send this particular friend id
//myIviteBundleparams.putString("to",
friendId);
final ImageView facebook1 = (ImageView) findViewById(R.id.facebook1);
facebook1.setOnClickListener(new OnClickListener() {

}
} catch (Exception e) {
