我有一个广播接收器类，它可以识别电话呼叫状态，（拨出，传入，，CALL_STATE_OFFHOOK）CALL_STATE_IDLE它适用于 android N 和较低版本，但对于 Android O，接收器无法识别呼叫是否已结束，没有CALL_STATE_IDLE状态, 但能正确识别传出、传入和CALL_STATE_OFFHOOK状态

private fun startListening(context: Context) {
    val telManager = context.getSystemService(Context.TELEPHONY_SERVICE) as? TelephonyManager
    telManager?.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE)
}


    private val phoneListener = object : PhoneStateListener() {
    override fun onCallStateChanged(state: Int, incomingNumber: String) {
        Log.e("CALL_STATE", "calling number $incomingNumber")
        try {
            when (state) {
                TelephonyManager.CALL_STATE_RINGING -> {
                    Log.e("CALL_STATE", "CALL_STATE_RINGING")
                }
                TelephonyManager.CALL_STATE_OFFHOOK -> {
                    Log.e("CALL_STATE", "CALL_STATE_OFFHOOK")
                }

                TelephonyManager.CALL_STATE_IDLE -> {
                    Log.e("CALL_STATE", "CALL_STATE_IDLE")
                }
                else -> {
                    Log.e("CALL_STATE", "CALL_STATE_IDLE")
                }
            }
        } catch (ex: Exception) {
            ex.printStackTrace()
        }

    }
}

清单.xml

    <receiver android:name=".MyPhoneCallStateReceiver">
        <intent-filter android:priority="989999">
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

我还发现，如果有来电，它会正确识别CALL_STATE_IDLE 状态何时触发

我错过了什么？
