Question

我正在我的应用中实现解析通知，这是我第一次使用推送通知。

我一直在关注this教程，以了解解析的工作方式！

然后我发现PushService.setDefaultPushCallback(this, MainActivity.class);已被弃用，并使用this作为指导。

我的代码如下：

AndroidManifest.xml：

MyBroadcastReceiver.java：

package com.example.pchakraverti.pushnotification;

import android.content.Context;
import android.content.Intent;
import android.util.Log;

import com.parse.ParsePushBroadcastReceiver;

/**

public class MyBroadcastReceiver extends ParsePushBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Log.i("TAG", "Push Received");

        /*Intent launchIntent = new Intent(context, MainActivity.class);
        PendingIntent pi = PendingIntent.getActivity(context, 0, launchIntent, 0);

        Notification notification = new NotificationCompat.Builder(context)
                .setContentTitle("Push Notification")
                .setContentText("hello")
                .setContentIntent(pi)
                .setAutoCancel(true)

        NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        nm.notify(0, notification);*/
    }
}

MainActivity.java：

package com.example.pchakraverti.pushnotification;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;

import com.parse.Parse;
import com.parse.ParseException;
import com.parse.ParseInstallation;
import com.parse.ParsePush;
import com.parse.SaveCallback;


public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Parse.initialize(this, "7Wm4v4FP28FHPW06zVBj6Ifcc8QeQObr3LUycs90", "U90b8QH4gLOXGfZLwBSqGqOZSo5GFLiu9sRi4bxW");

        ParsePush.subscribeInBackground("", new SaveCallback() {
            @Override
            public void done(ParseException e) {
                if (e == null) {
                    Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
                } else {
                    Log.e("com.parse.push", "failed to subscribe for push", e);
                }
            }
        });
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

当我从parse.com发送推送时，它说成功，但我没有在我的Android设备上收到任何内容。

修改的

我已根据官方教程更新了代码。但我仍然有问题。

我还缺少什么吗？

可以看出logcat提取中记录了一个“Push Received”。

但在那之后，我再也没有收到任何东西了！

发生了什么事？

Answer 1

一般来说，我推荐official tutorial。

您的com.parse.ParseBroadcastReceiver使用错误的操作名称，应阅读：

<receiver android:name="com.parse.ParseBroadcastReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
        <action android:name="android.intent.action.USER_PRESENT"/>
    </intent-filter>
</receiver>

你缺少这个接收器（上面链接的教程中的代码）：

<receiver android:name="com.parse.GcmBroadcastReceiver"
    android:permission="com.google.android.c2dm.permission.SEND">
  <intent-filter>
    <action android:name="com.google.android.c2dm.intent.RECEIVE" />
    <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

    <!--
      IMPORTANT: Change "com.parse.tutorials.pushnotifications" to match your app's package name.
    -->
    <category android:name="com.parse.tutorials.pushnotifications" />
  </intent-filter>
</receiver>

您必须通过订阅频道启用推送通知，例如：

ParsePush.subscribeInBackground("", new SaveCallback() {
    @Override
    public void done(ParseException e) {}
});

Answer 2

另一个常见原因可能是使用GCM控制台的服务器API密钥虽然应该使用来自Firebase项目的API密钥。

在Android中没有收到解析推送通知
