Hide Numbers from Dialed List after Call from React Native App: A Step-by-Step Guide

Are you tired of your React Native app revealing sensitive information to curious eyes? Do you want to keep your users’ dialed numbers private? Look no further! In this comprehensive guide, we’ll walk you through the process of hiding numbers from the dialed list after a call is made from your React Native app.

Why Hide Numbers from the Dialed List?

As a responsible app developer, it’s essential to prioritize your users’ privacy and security. When a user makes a call from your app, the dialed number is often stored in the phone’s call log. This can be a significant concern, especially if your app is used for sensitive or confidential communications. By hiding the numbers from the dialed list, you can ensure that your users’ privacy is protected and maintain their trust in your app.

How to Hide Numbers from the Dialed List in React Native

To achieve this, we’ll use a combination of platform-specific code and clever manipulation of the Android and iOS operating systems. Don’t worry; we’ll break it down into manageable chunks, so you can follow along easily.

Step 1: Android Solution

On Android, we’ll use the `android.provider.CallLog` class to manipulate the call log. Add the following code to your Android module:

import android.provider.CallLog;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;

public class CallLogHandler {
  public static void deleteCallLogEntry(Context context, String number) {
    Uri uri = CallLog.Calls.CONTENT_URI;
    String[] projection = new String[] { CallLog.Calls._ID };
    String selection = CallLog.Calls.NUMBER + " = ?";
    String[] selectionArgs = new String[] { number };
    Cursor cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null);
    if (cursor.moveToFirst()) {
      int id = cursor.getInt(0);
      context.getContentResolver().delete(uri, CallLog.Calls._ID + " = " + id, null);
    }
  }
}

import { NativeModules } from 'react-native';
const { CallLogHandler } = NativeModules;

const deleteCallLogEntry = (number) => {
  CallLogHandler.deleteCallLogEntry(number);
};

Step 2: iOS Solution

On iOS, we’ll use the `CoreTelephony` framework to access the call history. Add the following code to your iOS module:

#import <CoreTelephony/CTCall.h>

@interface CallLogHandler : NSObject

+ (void)deleteCallLogEntry:(NSString *)number;

@end

@implementation CallLogHandler

+ (void)deleteCallLogEntry:(NSString *)number {
  CTCall *call = [[CTCall alloc] init];
  [call deleteCallWithNumber:number];
}

@end

import { NativeModules } from 'react-native';
const { CallLogHandler } = NativeModules;

const deleteCallLogEntry = (number) => {
  CallLogHandler.deleteCallLogEntry(number);
};

Step 3: Integrate the Solution

Now that we have the platform-specific code in place, let’s integrate it into our React Native app. Create a new JavaScript file to handle the call log deletion:

import { Platform } from 'react-native';

const deleteCallLogEntry = (number) => {
  if (Platform.OS === 'android') {
    // Call the Android module
    deleteCallLogEntry(number);
  } else if (Platform.OS === 'ios') {
    // Call the iOS module
    deleteCallLogEntry(number);
  }
};

export default deleteCallLogEntry;

Finally, call the `deleteCallLogEntry` method whenever a call is made from your app, passing the dialed number as an argument:

import React, { useState, useEffect } from 'react';
import { View, Text, TouchableOpacity } from 'react-native';
import { deleteCallLogEntry } from './CallLogHandler';

const App = () => {
  const [number, setNumber] = useState('');
  const [calling, setCalling] = useState(false);

  useEffect(() => {
    if (calling) {
      // Make the call using your preferred method (e.g., React Native's `Linking` API)
      // ...
      // After the call is finished, delete the call log entry
      deleteCallLogEntry(number);
    }
  }, [calling]);

  const handleCall = () => {
    setCalling(true);
    // Make the call using your preferred method (e.g., React Native's `Linking` API)
    // ...
  };

  return (
    <View>
      <Text>Enter the number:</Text>
      <TextInput
        value={number}
        onChangeText={(text) => setNumber(text)}
        placeholder="1234567890"
      />
      <TouchableOpacity onPress={handleCall}>
        <Text>Make Call</Text>
      </TouchableOpacity>
    </View>
  );
};

export default App;

Additional Tips and Considerations

While the above solution works, there are some important aspects to keep in mind:

• Security**: Always handle sensitive information, like phone numbers, with care. Ensure you’re complying with relevant regulations and storing data securely.
• Platform limitations**: On Android, the `CallLog` class requires the `READ_CALL_LOG` permission, which may not be granted by the user. On iOS, the `CoreTelephony` framework has limitations on call history access. Research and understand these limitations to ensure your app complies with platform guidelines.
• Performance**: Deleting call log entries can impact performance, especially if your app makes frequent calls. Optimize your code to minimize the performance impact.
• User experience**: Be transparent with your users about the call log deletion process. Inform them about the privacy implications and ensure they understand the benefits.

Conclusion

By following this comprehensive guide, you’ve successfully implemented a solution to hide numbers from the dialed list after a call is made from your React Native app. Remember to consider the additional tips and considerations to ensure a seamless and secure user experience. With this approach, you can maintain your users’ trust and protect their privacy.

Platform	Solution
