Why my button work juste one time ? - Android studio

I am trying tp send sms by clicking a button bt this button is working juste one time.
And i don't know how I can get it so the button can be pressed an infinite amount of time.
Can you please help me to fix that.
this is my code :
Button sendBtn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sendBtn = (Button) findViewById(R.id.btnSendSMS);
sendBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
sendSMSMessage();
}
});
}
protected void sendSMSMessage() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode,String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("+212xxxxxx", null, "Je suis en danger, voici ma localisation : https://goo.gl/maps/xamxKW62p34wWpBU8", null, null);
Toast.makeText(getApplicationContext(),
"SMS sent.", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.", Toast.LENGTH_LONG).show();
return;
}
}
}
}

You are missing else branch in sendSMSMessage, so you are not sending SMS if SEND_SMS permission is already granted. You are also not doing anything if you need to show permission rationale, which results in a broken experience.
Overall I would suggest to read carefully the docs on requesting permissions. It explains both your approach with onRequestPermissionsResult as well as the new recommended way of using ActivityResultContracts.
Without rewriting your code to the contracts I would fix it like this:
protected void sendSMSMessage() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
// fixme: show explanation
// before requesting the permission again
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
} else {
sendSmsImpl();
}
}
#Override
public void onRequestPermissionsResult(int requestCode,String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
sendSmsImpl();
} else {
// fixme: explain that it can't send SMS without the permission
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.", Toast.LENGTH_LONG).show();
return;
}
// !!! NOTE: you still need break inside switch/case
// even with curly braces
break;
}
}
}
private void sendSmsImpl() {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("+212xxxxxx", null, "Je suis en danger, voici ma localisation : https://goo.gl/maps/xamxKW62p34wWpBU8", null, null);
//todo: use sentIntent argument of sendTextMessage to detect success/error
Toast.makeText(getApplicationContext(),
"SMS sent.", Toast.LENGTH_LONG).show();
}

call by phone number on button click (java)

I have a call method on button click
button_call=(Button) findViewById(R.id.button_call);
button_call.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent=new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:+79142214017"));
startActivity(intent);
}
});
And the data transfer method in Firebase
private void validateClientInfo() {
if (TextUtils.isEmpty(client_edit.getText().toString())) {
Toast.makeText(this, "Введите имя", Toast.LENGTH_SHORT).show();
}
if (TextUtils.isEmpty(client_number.getText().toString())){
Toast.makeText(this, "Введите номер", Toast.LENGTH_SHORT).show();
}
else {
HashMap<String, Object> userMap = new HashMap<>();
userMap.put("uid", mAuth.getCurrentUser().getUid());
userMap.put("numberphone_client",client_number.getText().toString());
clientRef.child(mAuth.getCurrentUser().getUid()).updateChildren(userMap);
startActivity(new Intent(ClientName.this,HomeActivity.class));
}
}
transcripts
client_number=(EditText) findViewById(R.id.client_number);
mAuth=FirebaseAuth.getInstance();
how to make it so that when the call button is pressed, the number is received and called?
I want that when the button _call button is pressed, the data transmitted by the transfer method is received and a call is made on them.

Request permission android.permission.CALL_PHONE before calling.
Add into AndroidManifest.xml:
<uses-permission android:name="android.permission.CALL_PHONE" />
Request permission before calling:
boolean isPermissionGranted = (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED);
if (isPermissionGranted) {
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + mNumber));
startActivity(intent);
} else {
Toast.makeText(this, "Отсутствует разрешение на звонок с устройства", Toast.LENGTH_SHORT).show();
ActivityCompat.requestPermissions(this, new String[]{ Manifest.permission.CALL_PHONE }, 0);
}
Add request result:
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull #NotNull String[] permissions, #NonNull #NotNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 0) {
for (int result : grantResults) {
if (result != PackageManager.PERMISSION_GRANTED) {
//RETURN, PERMISSION NOT GRANTED
Toast.makeText(this, "Вы не выдали разрешение, приложение может работать неккоректно!", Toast.LENGTH_SHORT).show();
return;
}
}
//PERMISSIONS GRANTED
Toast.makeText(this, "Спасибо за выданное разрешение!", Toast.LENGTH_SHORT).show();
}
}

If your are looking to call the selected number then just use the following code.
Intent intentCallForward = new Intent(Intent.ACTION_DIAL); // ACTION_CALL
Uri uri2 = Uri.fromParts("tel", "79142214017, "#");
intentCallForward.setData(uri2);
startActivityForResult(intentCallForward, 101);

Increment float number on phone state idle

I am trying to increment a float number once the Phone State is IDLE. Then save the float number in shared preferences and expose it in the main activity.
Currently what i did was use intent to take in the number on phone state and send to the main activity and on the main activity i saved it. But the phone crashes once i test it. Below is my current code for the Incoming Call:
public class IncomingCall extends BroadcastReceiver {
private View view;
#Override
public void onReceive(Context context, Intent intent) {
try {
System.out.println("Receiver start");
Intent intentBundle = new Intent();
Bundle bundle = new Bundle();
bundle.putFloat("value", 0.5f);
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
bundle.putFloat("value", 0.5f);
intentBundle.putExtras(bundle);
Toast toast = new Toast(context);
CharSequence text = "O.5 Added";
int duration = Toast.LENGTH_SHORT;
Toast testtoast = Toast.makeText(context, text, duration);
testtoast.show();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
Below is the code i have in my main activity:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private float minteger = 0.5f;
private Context context;
private Activity activity;
private static final int PERMISSION_REQUEST_CODE = 1;
private View view;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
SharedPreferences sharedPreferences = this.getSharedPreferences("com.appname.app", Context.MODE_PRIVATE);
sharedPreferences.edit().putFloat("value", minteger).apply();
Float value = sharedPreferences.getFloat("value", 0.0f);
TextView textv = (TextView) findViewById(R.id.numberValue);
textv.setText(String.valueOf(value));
context = getApplicationContext();
activity = this;
Button check_permission = (Button) findViewById(R.id.check_permission);
Button request_permission = (Button) findViewById(R.id.request_permission);
check_permission.setOnClickListener(this);
request_permission.setOnClickListener(this);
}
#Override
public void onClick(View v) {
view = v;
int id = v.getId();
switch (id) {
case R.id.check_permission:
if (checkPermission()) {
Snackbar.make(view, "Permission already granted.", Snackbar.LENGTH_LONG).show();
} else {
Snackbar.make(view, "Please request permission.", Snackbar.LENGTH_LONG).show();
}
break;
case R.id.request_permission:
if (!checkPermission()) {
requestPermission();
} else {
Snackbar.make(view, "Permission already granted.", Snackbar.LENGTH_LONG).show();
}
break;
}
}
private boolean checkPermission() {
int result = ContextCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE);
if (result == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
private void requestPermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.READ_PHONE_STATE)) {
Toast.makeText(context, "Phone state allows you to earn on incoming calls. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.READ_PHONE_STATE}, PERMISSION_REQUEST_CODE);
}
}
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Snackbar.make(view, "Permission Granted, Now you can access phone manager.", Snackbar.LENGTH_LONG).show();
} else {
Snackbar.make(view, "Permission Denied, You cannot access phone manager.", Snackbar.LENGTH_LONG).show();
}
break;
}
}
}

You could put the value to sharedpref in IncomingCall and retrieve in MainActivity.

send sms from SMSPortalFragment not working

I have been trying to send test messages from using send_sms api. My SMSPortalFragment.java code show no error. Also there is no other error shown in Logcat.
The code builds and installs in the Galaxy S8.
The app runs fun.
Going to fragment_smsportal.xml is working fine.
I can type in my name and message.
On button click it asks for my PERMISSION in runtime.
NO MESSAGE IS SENT EVEN AFTER I ALLOW PERMISSION.
java code:
private static final int MY_PERMISSIONS_REQUEST_SEND_SMS =0 ;
Button sendButon;
EditText fullName;
EditText textMessage;
String phoneNo = "***********";
String name;
String message;
String sendMessage;
public SMSPortalFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View smsportal = inflater.inflate(R.layout.fragment_smsportal, container, false);
fullName = (EditText) smsportal.findViewById(R.id.fullName);
textMessage = (EditText) smsportal.findViewById(R.id.textMessage);
sendButon = (Button) smsportal.findViewById(R.id.sendButon);
sendButon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
sendSMSMessage();
}
});
return smsportal;
}
private void sendSMSMessage() {
name = fullName.getText().toString();
message = textMessage.getText().toString();
sendMessage = name + " " + message;
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),
Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(getActivity(),
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode,String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, sendMessage, null, null);
Toast.makeText(getActivity(),"SMS sent.", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getActivity(),"SMS failed, please try again.", Toast.LENGTH_LONG).show();
}
}
}
}
Can anyone tell me what I am doing wrong?
PS: I removed my phone number from this code for security concern.

Do not write your send logic in onRequestPermissionsResult()
and
Try this...
Manifest permission
<uses-permission-sdk-23 android:name="android.permission.SEND_SMS"/>
and here is the snippet
try {
Bundle msgDataBundle = intent.getExtras();
String mobileNumber = msgDataBundle.getString("MobileNumber");
SmsManager smsManager = SmsManager.getDefault();
// smsManager.sendTextMessage(mobileNumber,null,"sam",null,null);
smsManager.sendTextMessage(mobileNumber, null, "Test Sample Message Text", null, null);
Toast.makeText(context, "SMS Sent!", Toast.LENGTH_LONG).show();
Log.d("---", "Sent");
} catch (Exception e) {
Toast.makeText(context, "SMS faild, please try again.", Toast.LENGTH_LONG).show();
Log.d("---", "Fail");
e.printStackTrace();
}

You can generate different random values like this.
System.currentTimeMillis(); //It return long value of current time. This value always will be unique.
