Question

我有一个广播接收器类，用于识别电话呼叫状态，（传出，传入，CALL_STATE_OFFHOOK，CALL_STATE_IDLE）它适用于Android N和较低版本，但对于Android O，接收器可以＆＃39; t确定呼叫是否已结束，没有CALL_STATE_IDLE状态，但正确识别出局，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()
        }

    }
}

的Manifest.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>

我所发现的是，如果呼叫是传入的，它会正确识别CALL_STATE_IDLE状态何时触发

我失踪了什么？

用于监控电话呼叫状态的BroadcastReceiver无法正常运行Android O API 27
