Cannot send sms verification code using with the SMS User Consent API on android

I am trying to make a phone number verification on android studio using java. I followed the instructions from the documentation here https://developers.google.com/identity/sms-retriever/user-consent/overview but sadly it isn't sending me an SMS code, and I am not getting any error. Below is my code:
public class OTPSMSActivity extends AppCompatActivity {

// Set to an unused request code
private final BroadcastReceiver smsVerificationReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
if (SmsRetriever.SMS_RETRIEVED_ACTION.equals(intent.getAction())) {
Bundle extras = intent.getExtras();
Status smsRetrieverStatus = (Status) extras.get(SmsRetriever.EXTRA_STATUS);
switch (smsRetrieverStatus.getStatusCode()) {
case CommonStatusCodes.SUCCESS:
// Get consent intent
Intent consentIntent = extras.getParcelable(SmsRetriever.EXTRA_CONSENT_INTENT);
try {

I want to know what am I doing wrong here.

Calling this API won't be sending you an SMS. This API listens to the SMS that you will receive on your device, ask for your permission and then retrieve it.
You should not wait for the task to complete. It is there to listen to the SMS you receive. So the first thing that you need to correct in your onCreate function:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_otpsms);
...
Task<Void> task = SmsRetriever.getClient(this).startSmsUserConsent(null);
IntentFilter intentFilter = new IntentFilter(SmsRetriever.SMS_RETRIEVED_ACTION);
registerReceiver(smsVerificationReceiver, intentFilter);
...
}
The phone number you are passing to SmsRetriever.getClient(this).startSmsUserConsent is the phone number of the sender. So if you know which number will send you an SMS, then pass it to this function. But if you don't know the number of the sender, keep it null.
And note that the sender phone number should not be in the phone's contacts list as mentioned in the documentation: https://developers.google.com/identity/sms-retriever/choose-an-api
So first call create this task instruction above, have it wait for your sms and then request an SMS. You could use third party platforms to send SMS messages. To test that you can send an SMS using your emulator to the emulator device.

How to do Call forwading from Android Application

I Want to do call forwarding from my application the scenario is when any GSM call came then from my application i want to forward that number to other desitination number.
Here i have done some code for Call forwarding but its not working. I have created Receiver and also declared in Manifest and has given Call permission.
But anyhow it is not working.
Manifests Code:-
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<receiver android:name=".PhoneStateReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
Receiver Code :-
public class PhoneStateReceiver extends BroadcastReceiver {
Context ctx;
#Override
public void onReceive(Context context, Intent intent) {
this.ctx=context;
try {
System.out.println("Receiver start");
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
System.out.println("Incoming Number" + incomingNumber);
System.out.println("INcoming State" + state);
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
Toast.makeText(context,"Incoming Call State",Toast.LENGTH_SHORT).show();
Toast.makeText(context,"Ringing State Number is -"+incomingNumber,Toast.LENGTH_SHORT).show();
String fwdMobNumVar = ("**21*" + "1234567890" + "#");
callforward(fwdMobNumVar);
}
if ((state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))){
Toast.makeText(context,"Call Received State",Toast.LENGTH_SHORT).show();
}
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
Toast.makeText(context,"Call Idle State",Toast.LENGTH_SHORT).show();
}
}
catch (Exception e){
e.printStackTrace();
}
}
private void callforward(String callForwardString) {
PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager)
ctx.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
Intent intentCallForward = new Intent(Intent.ACTION_CALL);
Uri mmiCode = Uri.fromParts("tel", callForwardString, ("#"));
intentCallForward.setData(mmiCode);
ctx.startActivity(intentCallForward);
}
public class PhoneCallListener extends PhoneStateListener
{
private boolean isPhoneCalling = false;
#Override
public void onCallStateChanged(int state, String incomingNumber)
{
if (TelephonyManager.CALL_STATE_RINGING == state)
{
// phone ringing
Toast.makeText(ctx,"Callforward ringing",Toast.LENGTH_SHORT).show();
}
if (TelephonyManager.CALL_STATE_OFFHOOK == state)
{
// active
Toast.makeText(ctx,"Callstate hook",Toast.LENGTH_SHORT).show();
isPhoneCalling = true;
}
if (TelephonyManager.CALL_STATE_IDLE == state)
{
// run when class initial and phone call ended, need detect flag
// from CALL_STATE_OFFHOOK
if (isPhoneCalling)
{
// restart app
Toast.makeText(ctx,"Call phone forwading ",Toast.LENGTH_SHORT).show();
Intent i = ctx.getPackageManager()
.getLaunchIntentForPackage(ctx.getPackageName());
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
ctx.startActivity(i);
isPhoneCalling = false;
}
}
}
}
}

How to update ListView with BroadcastReceiver?

I want update ListView from BroadcastReceiver in onReceiver event.
How to initialized ListView in this class then update to ListView:
public class CallBroadcast extends BroadcastReceiver {
private static int pState = TelephonyManager.CALL_STATE_IDLE;
#Override
public void onReceive(final Context context, final Intent intent) {
TelephonyManager telManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
telManager.listen(new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
callDAO = new CallDAO(context);
if (configPreferenceManager.getAutoRecord()) {
if (state != pState) {
if (state == TelephonyManager.CALL_STATE_OFFHOOK && callInfoPreferenceManager.getCallState()) {
uri = Uri.withAppendedPath(
ContactsContract.PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(callInfoPreferenceManager.getPhoneNumber()));
projection = new String[]{ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME
, ContactsContract.Contacts.PHOTO_ID
};
// START SERVICES TO RECORD CALL. AFTER IT, I WANT UPDATE MY LIST
sIntent = new Intent(context.getApplicationContext(),
CallRecordService.class);
context.startService(sIntent);
} else if (state == TelephonyManager.CALL_STATE_RINGING && callInfoPreferenceManager.getCallState()) {
callInfoPreferenceManager.setPhoneNumber(incomingNumber);
callInfoPreferenceManager.setSending(String.valueOf(false));
} else if (state == TelephonyManager.CALL_STATE_IDLE && callInfoPreferenceManager.getCallState() == CALLING) {
callDAO.insert(callInfoPreferenceManager.getName(),
callInfoPreferenceManager.getPhoneNumber(),
callInfoPreferenceManager.getStartDate()
+ configPreferenceManager.getPathFormat());
callDAO.close();
// Record call start service
sIntent = new Intent(context.getApplicationContext(),
CallRecordService.class);
context.stopService(sIntent);
callInfoPreferenceManager.setCallState(IDLE);
}
pState = state;
}
}
}
}, PhoneStateListener.LISTEN_CALL_STATE);
}//onReceive
}
In the code I posted is BroadcastReceiver class.
And I can't using getActivity() class or findViewById(a, b) when extends BroadcastReceiver.
How to fix this problem?

Start the activity that will populate the listview using Intents.
Intent intent = new Intent(context,Myactivity.class)
startactivity(intent);
To avoid multiple instances of same 'Myactivity', use appropriate flags in the Manifest file.
If you want to transfer data between your broadcastReceiver and 'Myactivity', either use intent.putExtra() or store the data into sharedPreferences

Android: pass variables from Activity to BroadcastReceiver

I have some problem with passing throught my variable from Activity to the BroadcastReceiver...
Here is my code:
here is my Broadcast receiver code... I try to catch SMS from one phone number which I have got from my Activity...
public class SMSMonitor extends BroadcastReceiver
{
private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
public static String phone_number = "";
public static String msg_body = "";
public static final String SMS_EXTRA_NAME = "pdus";
#Override
public void onReceive(Context context, Intent intent)
{
String phone = intent.getExtras().getString("trusted_num");
if (intent != null && intent.getAction() != null && ACTION.compareToIgnoreCase(intent.getAction()) == 0)
{
Object[] pduArray = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] messages = new SmsMessage[pduArray.length];
for (int i = 0; i < pduArray.length; i++)
{
messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);
}
phone_number = messages[0].getDisplayOriginatingAddress();
msg_body = messages[0].getMessageBody();
System.out.println("Phone number: "+phone_number);
System.out.println("Phone entered: "+phone);
}
}
}
Here is my Activity code:
public class Settings extends Activity implements OnClickListener{
private Button btn_save;
private EditText txt_phone;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
//set Save button
btn_save = (Button)findViewById(R.id.btn_save);
txt_phone = (EditText)findViewById(R.id.et_phone);
btn_save.setOnClickListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_settings, menu);
return true;
}
#Override
public void onClick(View v)
{
if (v == btn_save)
{
try
{
String phone_num = txt_phone.getText().toString();
Intent i = new Intent(Settings.this, SMSMonitor.class);
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
}
catch(Exception e)
{
System.out.println("Error: "+e.getLocalizedMessage());
}
}
}
}
In this code I have text field for entering the phone number, which I need to pass to the BroadcastReceiver with intent.putExtra() method, but in LogCat I see, that variable didnot pass:
07-25 18:43:57.382: I/System.out(14245): Phone number: +37129690449
07-25 18:43:57.382: I/System.out(14245): Phone entered: null
So what I am doing wrong here?
UPD
Maybe code is not correct, but it works for me...
public void onReceive(Context context, Intent intent)
{
phone = intent.getExtras().getString("trusted_num");//get trusted phone number from Settings screen
//receive SMS
if (intent != null && intent.getAction() != null && ACTION.compareToIgnoreCase(intent.getAction()) == 0)
{
Object[] pduArray = (Object[]) intent.getExtras().get("pdus");
SmsMessage[] messages = new SmsMessage[pduArray.length];
for (int i = 0; i < pduArray.length; i++)
{
messages[i] = SmsMessage.createFromPdu((byte[]) pduArray[i]);
}
phone_number = messages[0].getDisplayOriginatingAddress();
msg_body = messages[0].getMessageBody();
System.out.println("Phone number: "+phone_number);
}
//check if number is not null
if (phone != null && phone != "")
{
System.out.println("Phone entered: "+phone);
}
}
}

You can't pass an intent to a broadcast receiver. "There is no way for a BroadcastReceiver to see or capture Intents used with startActivity()"
https://developer.android.com/reference/android/content/BroadcastReceiver.html
I had a similar issue a while back and solved it by using a combination of IntentServices and Activities. You have to restructure your program to fit these guidlines

Well, there are some things not that don't match:
You're sending an intent with no action in the first place, but you're specifying Broadcastreceiver's class; don't do like that:
Intent i = new Intent(Settings.this, SMSMonitor.class);
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
But try instead:
Intent i = new Intent("my_package_name.Some_general_constant");
i.putExtra("trusted_num", phone_num);
sendBroadcast(i);
Then, your BroadcastReceiver is supposed to know that it can also handle "Some_general_constant" action. For this reason, register an extra action in your Manifest file for your SMSMonitor:
<receiver android:name=".package_to_bla_bla.SMSMonitor">
<intent-filter>
<action android:name="my_package_name.Some_general_constant"/>
</intent-filter>
</receiver>
Then in your SMSMonitor you need to add an else if statement to handle this broadcast:
else if("my_package_name.Some_general_constant".equals(intent.getAction())
{
// get the data from intent and use it
}

How to block Specific outgoing calls

I want to block a specific phone number that is in my database
I do a comparison between the number the user dialed, and the number in memory. If they are equal, I block the call.
My code:
public void onReceive(Context context, Intent intent) {
PlaceDataSQL placeDataSQL =new PlaceDataSQL(context);
ArrayList<String> getUsersPhoneNumbers= placeDataSQL.getUsersPhoneNumbers();
//TODO
//===========
//here I need to check the number
Bundle b = intent.getExtras();
String incommingNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
//String outGoingNumber = b.getString(TelephonyManager.);
Boolean find=false;
try {
for(int i=0;i<getUsersPhoneNumbers.size();i++)
{
if(incommingNumber.equals(getUsersPhoneNumbers.get(i)))
{
find=true;
break;
}
}
} catch (Exception e) {
incommingNumber="";
}
// ========================================
//here the problem
//=========================================
String phonenumber=b.getString(Intent.EXTRA_PHONE_NUMBER);
try {
for(int i=0;i<getUsersPhoneNumbers.size();i++)
{
if(phonenumber.equals(getUsersPhoneNumbers.get(i)))
{
find=true;
break;
}
}
if (!find)
return;
}catch (Exception e) {
phonenumber="";
}
if (!find)
return;
/* examine the state of the phone that caused this receiver to fire off */
String phone_state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (phone_state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
logMe("Phone Ringing: the phone is ringing, scheduling creation call answer screen activity");
Intent i = new Intent(context, CallAnswerIntentService.class);
i.putExtra("delay", 100L);
i.putExtra("number", incommingNumber);
context.startService(i);
logMe("Phone Ringing: started, time to go back to listening");
}
if (phone_state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
Intent i = new Intent(context,InCallScreenGuardService.class);
i.putExtra("delay", 100L);
i.putExtra("number", phonenumber);
logMe("Phone Offhook: starting screen guard service");
context.startService(i);
}
if (phone_state.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
Intent i = new Intent(context,InCallScreenGuardService.class);
logMe("Phone Idle: stopping screen guard service");
context.stopService(i);
}
return;
}
The problem:
I can get incoming numbers but I can't get outgoing numbers?

You will need a BroadcastReciever for this.
public class OutgoingCallReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
String phonenumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i("OutgoingCallReceiver",phonenumber);
Log.i("OutgoingCallReceiver",bundle.toString());
String info = "Detect Calls sample application\nOutgoing number: " + phonenumber;
Toast.makeText(context, info, Toast.LENGTH_LONG).show();
}
}
