I’m trying my best to track the listener’s call status but having some problems when stopping the app, the app fails to track when a call comes in.

Manifest

permission

    <uses-feature
        android:name="android.hardware.telephony"
        android:required="true" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.ANSWER_PHONE_CALLS" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission
        android:name="android.permission.WRITE_SETTINGS"
        tools:ignore="ProtectedPermissions" />

register broadcast receiver

<receiver
            android:name=".service.CallBroadcastReceiver"
            android:enabled="true"
            android:exported="false">
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
        </receiver>

handle when call state change

override fun onReceive(context: Context, intent: Intent) {
        try {
            if (intent.action == TelephonyManager.ACTION_PHONE_STATE_CHANGED) {
                val state = intent.getStringExtra(TelephonyManager.EXTRA_STATE)

                when (state) {

                    TelephonyManager.EXTRA_STATE_RINGING -> {
                        handleInComingCall(context)
                    }

                    TelephonyManager.EXTRA_STATE_OFFHOOK -> {
                        handleOutgoingCall(context)
                    }
                }
            }
        } catch (e: Exception) {
            e.message
        }

    }

thanks for any solution that help me!^^
