I have made an app in which first the user verifies its number with the help of sinch verification and then after succesfull verification it goes to the gameactivity but the problem is that every time the user opens the app he or she has to verify again which is a very bad out come.
i dont how o skip the verification process after again opening the app
Main Activity
public class MainActivity extends Activity {
public static final String SMS = "sms";
public static final String FLASHCALL = "flashcall";
public static final String INTENT_PHONENUMBER = "phonenumber";
public static final String INTENT_METHOD = "method";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TelephonyManager manager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
TextView phoneNumber = (TextView) findViewById(R.id.phoneNumber);
phoneNumber.setText(manager.getLine1Number());
}
private void openActivity(String phoneNumber, String method) {
Intent verification = new Intent(this, VerificationActivity.class);
verification.putExtra(INTENT_PHONENUMBER, phoneNumber);
verification.putExtra(INTENT_METHOD, method);
startActivity(verification);
}
private boolean checkInput() {
TextView phoneNumber = (TextView) findViewById(R.id.phoneNumber);
if (phoneNumber.getText().toString().isEmpty()) {
Toast.makeText(this, "Please input a phone number.", Toast.LENGTH_LONG).show();
return false;
}
return true;
}
public void onButtonClicked(View view) {
if (checkInput()) {
TextView phoneNumber = (TextView) findViewById(R.id.phoneNumber);
if (view == findViewById(R.id.smsVerificationButton)) {
openActivity(phoneNumber.getText().toString(), SMS);
} else if (view == findViewById(R.id.callVerificationButton)) {
openActivity(phoneNumber.getText().toString(), FLASHCALL);
}
}
}
}
Verification Activity
public class VerificationActivity extends Activity {
private static final String TAG = Verification.class.getSimpleName();

createVerification(phoneNumber, method);
}
}
void createVerification(String phoneNumber, String method) {
Config config = SinchVerification.config().applicationKey(APPLICATION_KEY).context(getApplicationContext())
.build();
VerificationListener listener = new MyVerificationListener();
Verification verification;
if (method.equalsIgnoreCase(MainActivity.SMS)) {

} else {
TextView messageText = (TextView) findViewById(R.id.textView);
messageText.setText(R.string.flashcalling);
verification = SinchVerification.createFlashCallVerification(config, phoneNumber, listener);
}
verification.initiate();
}
class MyVerificationListener implements VerificationListener {
#Override
public void onInitiated() {
Log.d(TAG, "Initialized!");
}
#Override
public void onInitiationFailed(Exception exception) {
Log.e(TAG, "Verification initialization failed: " + exception.getMessage());
hideProgress(R.string.failed, false);
}
#Override
public void onVerified() {
Log.d(TAG, "Verified!");
hideProgress(R.string.verified, true);
}
#Override
public void onVerificationFailed(Exception exception) {
Log.e(TAG, "Verification failed: " + exception.getMessage());
hideProgress(R.string.failed, false);
}
}
void hideProgress(int message, boolean success) {
if (success) {
ImageView checkMark = (ImageView) findViewById(R.id.checkmarkImage);
checkMark.setVisibility(View.VISIBLE);
}
ProgressBar progressBar = (ProgressBar) findViewById(R.id.progressIndicator);
progressBar.setVisibility(View.INVISIBLE);
TextView progressText = (TextView) findViewById(R.id.progressText);
progressText.setVisibility(View.INVISIBLE);
TextView messageText = (TextView) findViewById(R.id.textView);
messageText.setText(message);
}
}
I just want that on re opening verification process should not be again called.
You can use SharedPreferences. add a key to your SharedPreferences object and initialize with value 0. You can do something like below
SharedPrefences prefences = PrefenceManager.getSharedPreferences("TAG",Context.MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
Now on successfull verification :
preferences.putInt("key",1);
so on next launch check for this key value, if its 1 skip the VerificationActivity and start GameActivtiy i.e
int value = preferences.getInt("key",0);
if(value == 0){
// Verify
}else{
// Skip Verification
}

I am trying to create app that can connect to a MS SQL database when the user enters his username and password, I have tried multiple times and just cannot succeed. What would be the best way to connect my app?

you have two way
1 : Instead on mobile use this
Toast.makeText(getContext(),inputMobile.getText().toString(), Toast.LENGTH_SHORT).show();
2 : Create global string variable mobile like this
first create global mobile number above on onCreateView()
public String mobileNumber;
then in you button click in dialog init mobileNumber
try{
long number = Long.valueOf(inputMobile.getText().toString());
SPManipulation.getInstance(getActivity()).setMobile(inputMobile.getText().toString());
mTextMobile.setText(inputMobile.getText().toString());
FirebaseAuth mAuth = FirebaseAuth.getInstance();
String userID = mAuth.getCurrentUser().getUid();
mobileNumber = inputMobile.getText().toString();//THIS LINE CHANGED
DatabaseReference mynum = database.getReference().child(userID).child("number");
mynum.setValue(mobile);
}catch (Exception e){
Toast.makeText(getActivity(), "Please Input Correct Phone Number!", Toast.LENGTH_SHORT).show();
}
Now you can use mobileNumber anywhere like in button
mButtonCheckout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getContext(),mobileNumber, Toast.LENGTH_SHORT).show();
}
});
declare a String variable to store the value of the EditText
String mobileNumber = inputMobile.getText().toString();
Create your Toast inside the OnClickListener.
Toast.makeText(getContext, mobileNumber,Toast.LENGTH_LONG).show();
I have three activities, I capture all data but one from DetailActivity upon button click and save in database using Room; My intention is to insert all these data into the database and start ReviewActivity so as to get the arraylist of reviews and also insert it in the database.

Data gets loaded from MainActivity, the saved data is passed on to other activities as a parcellable bundle via intent, the passed data is displayed in DetailActivity but not in ReviewActivity.
Alternatively, if I can load reviews alongside YouTube keys from DetailActivity, I believe I can handle the database issue from there, but two Loaders wouldn't just work together, the app crashes; I am aware two AsyncTasks concurrently run together solved this problem, but I prefer to use Loaders because of performance on configuration change
I was tring to request tomcat for register information into the mysql table, the android studio occured crushed.I was using the okhttp3 for a request method.But I really can't find the mistake. Can you have a look at it and give me some advice?

The logcat information is that:
I am trying to develop an authentication android based webservice Rest,I am using the library Retrofit with async task as an inner class .
I have a variable called loginstatus returns true if the user exists otherwise false .
the problem is when the compiler out of the success method isloginstatus initializes to false.
Here is my activity code :
public class CheckLoginActivity extends Activity {
static AlertDialog dialog;
Button b;
UserModel userModel;
TextView statusTV;
EditText userNameET, passWordET;
String editTextUsername;
boolean loginStatus;
String editTextPassword;
String API_URL = "http://192.168.42.60/task_manager/v1/index.php";
SharedPreferences sharedpreferences;
public static final String USERPREFERENCE = "userPreference";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_check_login);
final TextInputLayout usernameWrapper = (TextInputLayout) findViewById(R.id.usernameWrapper);
final TextInputLayout passwordWrapper = (TextInputLayout) findViewById(R.id.passwordWrapper);
usernameWrapper.setHint("Username");
passwordWrapper.setHint("Password");
dialog = new SpotsDialog(this, "Chargement");
//NameText control
userNameET = (EditText) findViewById(R.id.editText1);
passWordET = (EditText) findViewById(R.id.editText2);
//Display Text control
statusTV = (TextView) findViewById(R.id.tv_result);
//Button to trigger web service invocation
b = (Button) findViewById(R.id.button1);
//Display progress bar until web service invocation completes
//Button Click Listener
sharedpreferences = getSharedPreferences(USERPREFERENCE, Context.MODE_PRIVATE);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Check if text controls are not empty
if (userNameET.getText().length() != 0 && userNameET.getText().toString() != "") {
if (passWordET.getText().length() != 0 && passWordET.getText().toString() != "") {
editTextUsername = userNameET.getText().toString();
editTextPassword = passWordET.getText().toString();
// statusTV.setText("");
//Create instance for AsyncCallWS
AsyncCallWS task = new AsyncCallWS();
//Call execute
task.execute(editTextUsername, editTextPassword);
}
//If Password text control is empty
else {
statusTV.setText("Please enter Password");
}
//If Username text control is empty
} else {
statusTV.setText("Please enter Username");
}
}
});
}
and my async task
private class AsyncCallWS extends AsyncTask<String, String, Void> {
//Make Progress Bar visible
protected void onPreExecute() {
dialog.show();
}
#Override
protected Void doInBackground(String... params) {
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint(API_URL)
.build();
geolocateApi post = restAdapter.create(geolocateApi.class);
post.login(editTextUsername, editTextPassword, new Callback<UserModel>() {
#Override
public void success(UserModel userModelRecv, Response response) {
if (userModelRecv != null) {
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString("username", userModelRecv.getUsername());
editor.putString("id", userModelRecv.getUser_id());
editor.putString("firstName", userModelRecv.getFirstName());
editor.putString("lastName", userModelRecv.getLastName());
editor.putString("Role", userModelRecv.getRole());
userModel=userModelRecv;
editor.commit();
loginStatus=true;
}else loginStatus=false;
}
#Override
public void failure(RetrofitError error) {
}
});
return null;
}
#Override
//Once WebService returns response
protected void onPostExecute(Void result) {
//Make Progress Bar invisible
Intent intSucces = new Intent(CheckLoginActivity.this, HomeActivity.class);
try {
Thread.sleep(200);
} catch (Exception e) {
e.printStackTrace();
}
dialog.hide();
//Error status is false
if (loginStatus) {
//Based on Boolean value returned from WebService
//Navigate to Home Screen
startActivity(intSucces);
} else {
//Set Error message
statusTV.setText("Login Failed, try again");
}
}
}
my interface Retrofit
public interface geolocateApi {
#FormUrlEncoded
#POST("/login")
public boolean login(#Field("username") String username,#Field("password") String password, Callback<UserModel> response);
}
Thanks for your help
You are using Retrofit for your login with a callback which basically sends request asynchronously. So by the time your onPostExecute is executed retrofit request might still be processing leaving your loginStatus to default false value. You don't need AsyncTask here as login already is running in background. It should be something like this
public class CheckLoginActivity extends Activity {
static AlertDialog dialog;
Button b;
UserModel userModel;
TextView statusTV;
EditText userNameET, passWordET;
String editTextUsername;
boolean loginStatus;
String editTextPassword;
String API_URL = "http://192.168.42.60/task_manager/v1/index.php";
SharedPreferences sharedpreferences;
public static final String USERPREFERENCE = "userPreference";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_check_login);
final TextInputLayout usernameWrapper = (TextInputLayout) findViewById(R.id.usernameWrapper);
final TextInputLayout passwordWrapper = (TextInputLayout) findViewById(R.id.passwordWrapper);
usernameWrapper.setHint("Username");
passwordWrapper.setHint("Password");
dialog = new SpotsDialog(this, "Chargement");
//NameText control
userNameET = (EditText) findViewById(R.id.editText1);
passWordET = (EditText) findViewById(R.id.editText2);
//Display Text control
statusTV = (TextView) findViewById(R.id.tv_result);
//Button to trigger web service invocation
b = (Button) findViewById(R.id.button1);
//Display progress bar until web service invocation completes
//Button Click Listener
sharedpreferences = getSharedPreferences(USERPREFERENCE, Context.MODE_PRIVATE);
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Check if text controls are not empty
if (userNameET.getText().length() != 0 && userNameET.getText().toString() != "") {
if (passWordET.getText().length() != 0 && passWordET.getText().toString() != "") {
editTextUsername = userNameET.getText().toString();
editTextPassword = passWordET.getText().toString();
// statusTV.setText("");
//Create instance for AsyncCallWS
RestAdapter restAdapter = new RestAdapter.Builder()
.setEndpoint(API_URL)
.build();
geolocateApi post = restAdapter.create(geolocateApi.class);
post.login(editTextUsername, editTextPassword, new Callback<UserModel>() {
#Override
public void success(UserModel userModelRecv, Response response) {
dialog.hide();
if (userModelRecv != null) {
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString("username", userModelRecv.getUsername());
editor.putString("id", userModelRecv.getUser_id());
editor.putString("firstName", userModelRecv.getFirstName());
editor.putString("lastName", userModelRecv.getLastName());
editor.putString("Role", userModelRecv.getRole());
userModel = userModelRecv;
editor.commit();
loginStatus = true;
Intent intSucces = new Intent(CheckLoginActivity.this, HomeActivity.class);
startActivity(intSucces);
} else {
loginStatus = false;
statusTV.setText("Login Failed, try again");
}
}
#Override
public void failure(RetrofitError error) {
}
});
}
//If Password text control is empty
else {
statusTV.setText("Please enter Password");
}
//If Username text control is empty
} else {
statusTV.setText("Please enter Username");
}
}
});
}
}
