Kotlin: How to get Custom Intent in Broadcast?-CodePudding

I create Custom Intent as below.

Intent().also { intent ->
    intent.setAction("STEP_COUNT_NOTIFICATION")
    intent.putExtra("stepCount", todayTotalStepCount)
    sendBroadcast(intent)
}

And I add this Custom Intent in my Broadcast Receiver tag of AndroidManifest.

<receiver
    android:name=".BroadcastReceiver.BroadcastReceiver"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.ACTION_DATE_CHANGED" />
        <action android:name="com.chungchunon.chunchunon_android.STEP_COUNTER_NOTIFICATION" />
    </intent-filter>
</receiver>

Since I use two Intent, one is official intent and the other is custom, I need to distinguish received Intent.

onReceive function of BroadcastReceiver

    override fun onReceive(context: Context?, intent: Intent?) {
        val intentAction = intent!!.action
        when (intentAction) {
            Intent.ACTION_DATE_CHANGED -> {
//                todayTotalStepCount = 0
                var todayStepCountSet = hashMapOf<String, Int?>(
                    "todayStepCount" to 0
                )
                userDB
                    .document("$userId")
                    .set(todayStepCountSet, SetOptions.merge())
            }
            
            ???? ->

        }
    }

How can I get STEP_COUNT_NOTIFICATION which is my custom intent?

CodePudding user response：

Your Intent action needs to match the android:name for the corresponding <intent-filter>. Yours do not.

You have:

intent.setAction("STEP_COUNT_NOTIFICATION")

This has an action string of STEP_COUNT_NOTIFICATION.

You also have:

        <action android:name="com.chungchunon.chunchunon_android.STEP_COUNTER_NOTIFICATION" />

This has an action string of com.chungchunon.chunchunon_android.STEP_COUNTER_NOTIFICATION.

Those two are not the same. They need to be the same. I recommend using com.chungchunon.chunchunon_android.STEP_COUNTER_NOTIFICATION in both places.

CodePudding user response：

First, create a public constant for your custom action:

 companion object {
        const val ACTION_STEP_COUNTER_NOTIFICATION = "com.chungchunon.chunchunon_android.STEP_COUNTER_NOTIFICATION"
 }

For your Intent, use the same action:

Intent().also { intent ->
    intent.setAction(ACTION_STEP_COUNTER_NOTIFICATION)
    intent.putExtra("stepCount", todayTotalStepCount)
    sendBroadcast(intent)
}

Also, use the same action in your BroadcastReceiver:

override fun onReceive(context: Context?, intent: Intent?) {
        val intentAction = intent!!.action
        when (intentAction) {
            Intent.ACTION_DATE_CHANGED -> {
//                todayTotalStepCount = 0
                var todayStepCountSet = hashMapOf<String, Int?>(
                    "todayStepCount" to 0
                )
                userDB
                    .document("$userId")
                    .set(todayStepCountSet, SetOptions.merge())
            }

            // Your custom action
            ACTION_STEP_COUNTER_NOTIFICATION -> { // Add your code here }

        }
    }

Lastly, for AndroidManifest.xml:

<receiver
    android:name=".BroadcastReceiver.BroadcastReceiver"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.ACTION_DATE_CHANGED" />

        // action should be the same as the value of ACTION_STEP_COUNTER_NOTIFICATION
        <action android:name="com.chungchunon.chunchunon_android.STEP_COUNTER_NOTIFICATION" />
    </intent-filter>
</receiver>

action name should be the same for Intent, AndroidManifest.xml and BroadcastReceiver
