Question

经过两天的挣扎，我不知道该怎么办，所以我在这里问...

我用最简单的方法用android和firebase进行推送通知。我安装了firebase引擎，在我的电脑上用nexus 4在android模拟器上做了一个简单的测试，一切运行良好，我有一个实例ID，我能看到通知，一切都很好。

一小时后，由于某种原因我出于某种原因停止获取新的实例ID（令牌）。

这些是我得到的日志： D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization. I/dalvikvm: Could not find method android.content.Context.getNoBackupFilesDir, referenced from method com.google.android.gms.common.util.zzx.getNoBackupFilesDir D/FirebaseApp: com.google.firebase.crash.FirebaseCrash is not linked. Skipping initialization. I/dalvikvm: Could not find method android.content.pm.PackageManager.getPackageInstaller, referenced from method com.google.android.gms.common.zze.zzm I/FirebaseInitProvider: FirebaseApp initialization successful

我在某些地方看到我需要确保我的模拟器已更新，所以我认为我更新了它，但现在我什么都没有。奇怪的是我能得到通知，但是（！）我不再得到令牌......

我正在使用两个服务类，一个用于生成新令牌（似乎不起作用），另一个用于接收通知（这似乎工作正常）。

这是生成令牌：

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

private static final String TAG = "MyFirebaseIIDService";

@Override
public void onTokenRefresh() {

    //Getting registration token
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();

    //Displaying token on logcat
    //Toast.makeText(MyFirebaseInstanceIDService.this, "testt", Toast.LENGTH_LONG).show();
    Log.d(TAG, "Refreshed token: " + refreshedToken);
    //sendRegistrationToServer(refreshedToken);
}

这是收到通知：

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        //Displaying data in log
        //It is optional
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());

        //Calling method to generate notification
        sendNotification(remoteMessage.getNotification().getBody());
    }

    //This method is only generating push notification
    //It is same as we did in earlier posts
    private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("title")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notificationBuilder.build());
    }
}

这些是分级文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "app id"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 3
        versionName "1.2"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.mcxiaoke.volley:library-aar:1.0.0'
    compile 'com.android.support:recyclerview-v7:23.1.1'
    compile 'com.android.support:cardview-v7:23.1.1'
    compile 'com.android.support:support-v4:23.1.1'
    compile 'com.facebook.android:facebook-android-sdk:[4,5)'
    compile 'com.google.firebase:firebase-messaging:9.2.1'
}

apply plugin: 'com.google.gms.google-services'

和主要的gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.google.gms:google-services:3.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是显示（相关部分）：

    </application>

有什么帮助吗？
