How to make a contact ring on silent android

Have you ever missed an important call because your ‍Android ​phone was on silent mode? It can‍ be frustrating and inconvenient, especially if‍ you ‌are expecting an urgent call ⁤from a specific contact. Fortunately, ‍there is a way to make⁣ a contact ring even when your phone is on silent ​mode‌ on Android.‍ In‍ this ‌article, we will guide you through the ⁢process of making ‌a ⁢contact ring on ⁤silent Android, using HTML to incorporate the necessary ‍code.⁢

Step 1: Adding Permissions to Manifest⁣ File

To make⁤ a contact ring on silent Android, we first need to add the necessary permissions to the AndroidManifest.xml file.‍ This file contains important information about ‍your Android app, including the permissions it requires. Open your project in Android Studio and locate the AndroidManifest.xml file in the app > main directory.


    package="com.example.yourpackage">




...


In the code snippet ​above, we have added two permissions: READ_PHONE_STATE and MODIFY_AUDIO_SETTINGS.‌ The READ_PHONE_STATE permission allows the app to access the​ phone state, and the MODIFY_AUDIO_SETTINGS ⁣ permission allows the app ‌to modify audio⁣ settings. These permissions ​are necessary‍ for our‍ app to change the phone’s⁢ ringer mode programmatically.

Step 2: Creating‍ the SilentRinger Class

Next, we need⁢ to‌ create‍ a new Java class called SilentRinger, which will handle the logic for making‍ the contact ring on silent Android. In‍ Android Studio, ‌right-click ⁤on your ⁢app package and select New >‍ Java Class.⁢ Name the class as “SilentRinger” and click on the “OK” button. ‍

public class SilentRinger {

public static void makeContactRing(Context context, String contactName) {
AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
ContentResolver contentResolver = context.getContentResolver();

Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(contactName));
Cursor cursor = contentResolver.query(lookupUri, new String[]{ContactsContract.PhoneLookup.NUMBER}, null, null, null);

if (cursor != null && cursor.moveToFirst()) {
String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.NUMBER));

if (phoneNumber != null) {
audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.silenceRinger();
telephonyManager.listen(new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
if (state == TelephonyManager.CALL_STATE_IDLE) {
audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
}
}
}, PhoneStateListener.LISTEN_CALL_STATE);
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));
context.startActivity(callIntent);
}
}

if (cursor != null) {
cursor.close();
}
}
}

The​ SilentRinger class contains a static method⁤ called makeContactRing, which takes two parameters: a​ Context object​ and the ‍name ​of the contact you want to ⁢make ring.⁣ This⁤ method uses the PhoneLookup content provider ‌to find the phone⁤ number associated with the contact name. Once the phone number is retrieved, the setRingerMode method is called⁢ to change the phone’s ringer mode to normal, and⁣ the silenceRinger method is used to stop the incoming call ringtone. A PhoneStateListener is also ⁤registered ⁢to listen ⁤for ⁤the call state. When the call state becomes idle, indicating ⁤the ⁣call has ended, the ringer mode is set back to silent.​ Finally, an intent to make a call is created and started ‌with ⁣the retrieved phone number.

Step 3: Integrating HTML and⁣ JavaScript

Now that ‍we ⁤have the necessary Java code to make a contact ring on silent Android, ⁢we ⁤can integrate it‌ with ‌HTML and ⁢JavaScript. In your HTML ⁤file, add a button ⁣with an id and an onclick attribute:

In ⁢your JavaScript file, add the following code:

function makeContactRing() {
var contactName = prompt("Enter the name of the contact to ring:");

if (contactName !== null && contactName.trim() !== "") {
SilentRinger.makeContactRing(context, contactName);
}
}

The ‌JavaScript⁣ code ⁣defines‍ a function ⁤called ‍ makeContactRing that⁤ prompts​ the user to enter⁤ the‌ name of ‍the ⁢contact they ​want ‍to make ring. If a valid name is ⁤provided, ‌it calls the makeContactRing method of the SilentRinger‌ class ⁢with the provided contact name. Note‍ that⁣ the ⁣ context ⁣ parameter ⁣is not available in JavaScript, ​so ⁤you need to replace it with‍ the appropriate Android context. This​ can be achieved by using a WebView in your Android app, which allows you to execute JavaScript code within the WebView ⁤and pass the ​necessary​ context from the Java⁢ code to JavaScript.

Now you have successfully integrated the HTML and JavaScript code to ⁢make a contact​ ring on silent Android. When the ‍user clicks the “Make Contact Ring” button, they will be prompted to enter ⁢the name of‌ the contact they ‍want ⁣to make ring. Once a ⁣valid name is ⁣provided, the ‌SilentRinger class will handle the logic to change ⁤the phone’s ringer mode⁣ and initiate a call⁣ to the ‌specified contact.
