服务未销毁

Question

我正在用android开发一个自动短信回复应用程序，因此我需要每当用户选择启动该服务时，用户都应仅单击该按钮，之后广播公司才应对SMS_RECEIVED广播做出反应，但是无论何时我启动广播开始对此应用程序做出反应。请为我提供帮助。

请注意，仅在服务启动时才应接收广播接收器

这是我的MainACtivity.kt

    companion object
    {
        private const val TAG="AnoReplier"
        private val permissions= arrayOf(Manifest.permission.READ_SMS,Manifest.permission.SEND_SMS,Manifest.permission.RECEIVE_SMS,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE)
        private const val REQUEST_CODE_PERMISSIONS=1

lateinit var service:Intent
        lateinit var inst:MainActivity

        fun getInstance():MainActivity
        {
            return inst
        }
    }

    override fun onStart() {
        super.onStart()
        inst=this
        service=Intent(baseContext,SMSService::class.java)
    }

    override fun onCreate(savedInstanceState: Bundle?) {

                super.onCreate(savedInstanceState)
                setContentView(R.layout.activity_main)



        servicebutton.setOnCheckedChangeListener{ compoundButton: CompoundButton, b: Boolean ->
if(b)
{
    Log.d(TAG,"True condition of toggle button")
    startService(service)
    Log.d(TAG,"Service started")
    compoundButton.setBackgroundColor(Color.GREEN)
}
            else
{
    stopService(service)
    compoundButton.setBackgroundColor(Color.RED)
}
        }


    }

}

这是我的服务类代码，在其中注册了广播

class SMSService: Service() {
lateinit var broadcastReceiver: BroadcastReceiver
private val TAG="SMS Service"
    override fun onCreate() {

         var filter=IntentFilter()
        filter.addAction("android.provider.Telephony.SMS_RECEIVED")

        var generator=SMSBroadcastGenerator()
        broadcastReceiver=SMSBroadcastGenerator()

        registerReceiver(broadcastReceiver,filter)

    }



    override fun onBind(p0: Intent?): IBinder? {
       return null
    }

    override fun onDestroy() {

        Toast.makeText(MainActivity.getInstance(),"Background Service has started",Toast.LENGTH_SHORT).show()
        unregisterReceiver(broadcastReceiver)
        Log.d(TAG,"Receiver Unregistered")
        super.onDestroy()


    }


}

这是我的广播课的代码

class SMSBroadcastGenerator:BroadcastReceiver() {
    override fun onReceive(p0: Context?, intent: Intent?) {
        try {
            var action:String?=intent?.action
            if(action.equals("android.provider.Telephony.SMS_RECEIVED"))
            {


                var data=intent?.extras?.get("pdus") as Array<*>
                var msg=""
                for(i in 0 until data.size)
                {
                    var format=intent?.extras?.getString("format")
                    var message=SmsMessage.createFromPdu(data[i] as ByteArray ,format)
                    msg+=message.originatingAddress

                }




            }

        }
        catch(exc:Exception)
        {
            Log.e("SMSBroadcast Receiver","An error occured.Details: ${exc}")
        }

    }


}

这是我的Maanifest.xml：-

        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">


        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:name=".SMSBroadcastGenerator">
<intent-filter>
    <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>

        </receiver>
        <service android:name=".SMSService"/>
    </application>
