Using GCM in android studio

问题:

I don't know how to get GCM working in my project in android studio.

When I use some of the clases of GCM, y get this: Can't resolve symbol GCMRegistrar In this code:

GCMRegistrar.checkDevice(this);

And it does not show the option to import the class.

This is my graddle file:

    buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.8.0'

    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:19.0.1'
    compile 'com.google.android.gms:play-services:4.2.42'
}

This is my manifest:

        <activity

        </activity>

        <meta-data android:name="com.google.android.gms.version"
                   android:value="@integer/google_play_services_version" />

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyCgQNclD9ZqxhiJXGdFvTTx2OiR_vKfJCM"/>

        <receiver
            android:name=".GCMBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>

                <!-- Receives the actual messages. -->
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <!-- Receives the registration id. -->
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="com.javapapers.android" />
            </intent-filter>
        </receiver>

        <service android:name="com.compage.womenshield.notification.GCMIntentService" />

    </application>

</manifest>

It shows error in here:

<receiver
                android:name=".GCMBroadcastReceiver"

In the clase name. And here:

<service android:name="com.compage.womenshield.notification.GCMIntentService" />

How can I use these gcm classes in android studio?

回答1:

You are probably using an old tutorial but GCMRegistrar is a deprecated API class.

You should really be using the new one, as it will be removed soon.

Please use the GoogleCloudMessaging API instead.

回答2:

You are using older way. you should check official documentation of google to use gcm in your app. now Instance ID is used to get token

String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId),
        GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
