How to change ionic 2 local push notification icon?

问题

I have created a hybrid app using ionic2 in that I am using cordova local push notification.

Everything working perfectly only thing is not able change a icon, in below I have paste my code here.

LocalNotifications.schedule({
        id:1,
        title: "Test Title",
        text: "Push Notification",
        icon: "res://icon.png",
        at: new Date(new Date().getTime() + 5 * 1000),
        sound: null,
        every: "minute"          
    });

And also I tried this below code.

 LocalNotifications.schedule({
        id:1,
        title: "Test Title",
        text: "Push Notification",
        icon: "http://icons.iconarchive.com/icons/treetog/junior/256/camera-icon.png",
        at: new Date(new Date().getTime() + 5 * 1000),
        sound: null,
        every: "minute"          
    });

If I am using remote url the app forced to stop. Any one help me to solve this.

Assuming that you have stored your icon.png in your res directory!

There are two methods that you can use to direct to res folder and its content:

• res://drawable/icon2.png : that directs to the res-folder and its subfolder drawable itself
• file://res/drawable/koala6.jpg : that starts at the root of your platform directory and directs to another icon

I have used two 50x50 size icons that are stored in: platforms/android/res/drawable

and are named: koala6.jpg and icon2.png

But you can store your icons in any sub-directory of res.

You can show one of these two images by using one of the methods shown above:

LocalNotifications.schedule({
    id:1,
    title: "Test Title",
    text: "Push Notification",

    // method 1:
    icon: 'res://drawable/icon2', 

    // method 2:
    //icon: "file://res/drawable/koala6", 

    at: new Date(new Date().getTime() + 5 * 1000),
    sound: null,
    every: "second"
});

As this example shows the image-extensions (.png, .jpg) are left out.

When you want to show 50x50 images via url:

Define some permissions in your AndroidManifest.xml:

<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="1" android:versionName="0.0.1" package="io.ionic.starter" xmlns:android="http://schemas.android.com/apk/res/android">
    <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" />
    <uses-permission android:name="android.permission.INTERNET" />
    <application android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name" android:supportsRtl="true">
        <activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/activity_name" android:launchMode="singleTop" android:name="MainActivity" android:theme="@android:style/Theme.DeviceDefault.NoActionBar" android:windowSoftInputMode="adjustResize">
            <intent-filter android:label="@string/launcher_name">
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <receiver android:exported="false" android:name="de.appplant.cordova.plugin.localnotification.TriggerReceiver" />
        <receiver android:exported="false" android:name="de.appplant.cordova.plugin.localnotification.ClearReceiver" />
        <activity android:exported="false" android:launchMode="singleInstance" android:name="de.appplant.cordova.plugin.localnotification.ClickActivity" android:theme="@android:style/Theme.NoDisplay" />
        <receiver android:exported="false" android:name="de.appplant.cordova.plugin.notification.TriggerReceiver" />
        <receiver android:exported="false" android:name="de.appplant.cordova.plugin.notification.ClearReceiver" />
        <receiver android:exported="false" android:name="de.appplant.cordova.plugin.localnotification.RestoreReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
        <activity android:exported="false" android:launchMode="singleInstance" android:name="de.appplant.cordova.plugin.notification.ClickActivity" android:theme="@android:style/Theme.NoDisplay" />
    </application>
    <uses-sdk android:minSdkVersion="16" android:targetSdkVersion="23" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <!-- these two are added -->
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>

Then you can show them as you did it by using image-extensions (.png, .jpg)

Hope this helps.

回答2:

Put your icon.png file in src\assets\img directory for icon and for small icon put icon.png file in platforms\android\res\drawable directory

this.notification = {
    id: inc++,
    title: 'your title',
    text: "your text",
    icon:'file://assets/img/icon.png',
    smallIcon:'res://icon',
    sound: 'file://assets/sounds/sms.mp3',
    data: { mydata: 'My hidden message this is' },
    at: timestamp
};
this.notifications.push(this.notification);
