I am a newbie on android development and I'm trying to create an sms Reciever app but it is not working. I want the broadcast receiver to capture incoming messages and pass them to the Recycler view so that they can be displayed. At the moment nothing is being displayed.
here is my code (Manifest File)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test1">
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.Test1">
<receiver
android:name=".SmsReceiver"
android:enabled="true"
android:exported="true"></receiver>
<activity
android:name=".MainActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
here is the MainActivity file
package com.example.test1;
import android.content.ContentResolver;
import android.content.pm.PackageManager;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
//recycler view
private RecyclerView recyclerView;
private ArrayList<SmsModel>smsModel=new ArrayList<>();
private static MainActivity inst;
public static MainActivity instance() {
return inst;
}
@Override
public void onStart() {
super.onStart();
inst = this;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView=findViewById(R.id.smsRecycler);
ArrayAdapter adapter= new ArrayAdapter();
adapter.setSmsModel(smsModel);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
if(ContextCompat.checkSelfPermission(getBaseContext(), "android.permission.READ_SMS") == PackageManager.PERMISSION_GRANTED) {
refreshSmsInbox();
}else {
// Todo : Then Set Permission
final int REQUEST_CODE_ASK_PERMISSIONS = 123;
ActivityCompat.requestPermissions(MainActivity.this, new String[]{"android.permission.READ_SMS"}, REQUEST_CODE_ASK_PERMISSIONS);
}
}
public void refreshSmsInbox() {
ContentResolver contentResolver = getContentResolver();
Cursor smsInboxCursor = contentResolver.query(Uri.parse("content://sms/inbox"), null, null, null, null);
int indexBody = smsInboxCursor.getColumnIndex("body");
int indexAddress = smsInboxCursor.getColumnIndex("address");
if (indexBody < 0 || !smsInboxCursor.moveToFirst()) return;
smsModel.clear();
do {
String str = "SMS From: " + smsInboxCursor.getString(indexAddress) +
"\n" + smsInboxCursor.getString(indexBody) + "\n";
smsModel.add((SmsModel) smsInboxCursor);
} while (smsInboxCursor.moveToNext());
}
public void updateList(final String smsMessage) {
}
}
Here is my Recyclerview Adapter class
package com.example.test1;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import java.util.ArrayList;
import java.util.List;
public class ArrayAdapter extends RecyclerView.Adapter<ArrayAdapter.viewHolder> {
private ArrayList<SmsModel>smsModel=new ArrayList<>();
public ArrayAdapter() {
}
@NonNull
@Override
public viewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.smsview,parent,false);
viewHolder viewHolder=new viewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(@NonNull viewHolder holder, int position) {
holder.ContactsNO.setText(smsModel.get(position).getContactNumber());
holder.SmsText.setText(smsModel.get(position).getContactSms());
holder.Time.setText(smsModel.get(position).getTime());
holder.Number.setText(smsModel.get(position).getNumber());
}
@Override
public int getItemCount() {
return smsModel.size();
}
public void setSmsModel(ArrayList<SmsModel> smsModel) {
this.smsModel = smsModel;
notifyDataSetChanged();
}
public class viewHolder extends RecyclerView.ViewHolder {
private TextView ContactsNO;
private TextView SmsText;
private TextView Time;
private TextView Number;
public viewHolder(@NonNull View itemView) {
super(itemView);
ContactsNO=itemView.findViewById(R.id.contactsNo);
SmsText=itemView.findViewById(R.id.smsText);
Time=itemView.findViewById(R.id.time);
Number=itemView.findViewById(R.id.Number);
}
}
}
And here is my Sms Receiver Class
package com.example.test1;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;
import androidx.annotation.RequiresApi;
public class SmsReceiver extends BroadcastReceiver {
public static final String SMS_BUNDLE = "pdus";
@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onReceive(Context context, Intent intent) {
Bundle intentExtras = intent.getExtras();
if (intentExtras != null) {
Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
String smsMessageStr = "";
for (int i = 0; i < sms.length; ++i) {
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);
String smsBody = smsMessage.getMessageBody().toString();
String address = smsMessage.getOriginatingAddress();
smsMessageStr += "SMS From: " + address + "\n";
smsMessageStr += smsBody + "\n";
}
Toast.makeText(context, smsMessageStr, Toast.LENGTH_SHORT).show();
//this will update the UI with message
MainActivity inst = MainActivity.instance();
inst.updateList(smsMessageStr);
}
}
}
here is my sms model class
package com.example.test1;
public class SmsModel {
private String Id;
private String ContactNumber;
private String ContactSms;
private String Time;
private String Number;
public SmsModel(String id, String contactNumber, String contactSms, String time, String number) {
Id = id;
ContactNumber = contactNumber;
ContactSms = contactSms;
Time = time;
Number = "Number";
}
public String getId() {
return Id;
}
public void setId(String id) {
Id = id;
}
public String getContactNumber() {
return ContactNumber;
}
public void setContactNumber(String contactNumber) {
ContactNumber = contactNumber;
}
public String getContactSms() {
return ContactSms;
}
public void setContactSms(String contactSms) {
ContactSms = contactSms;
}
public String getTime() {
return Time;
}
public void setTime(String time) {
Time = time;
}
public void setNumber(String number) {
Number = number;
}
public String getNumber() {
return Number;
}
@Override
public String toString() {
return "SmsModel{" +
"Id='" + Id + '\'' +
", ContactNumber='" + ContactNumber + '\'' +
", ContactSms='" + ContactSms + '\'' +
", Time='" + Time + '\'' +
", Number='" + Number + '\'' +
'}';
}
}
here is my main Activity code
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView

android:textStyle="bold"/>
<androidx.recyclerview.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/sms"
android:id="@+id/smsRecycler"
/>
</RelativeLayout>
and my layout resource file(smsview.xml)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp">

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_toRightOf="@+id/Number"
android:text="0700000000" />
<TextView
android:id="@+id/smsText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/Number"
android:layout_marginTop="10dp"

<TextView

android:layout_marginLeft="200dp"

</RelativeLayout>
