How to address android lint complaint about exported Firebase Messaging service implementations?

Following the Google developer instructions on implementing Firebase in my app, I notice that android lint complains.
The idea is that we have to implement two services which inherit from Firebase services:
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService { ... }
public class MyFirebaseMessagingService extends FirebaseMessagingService { ... }
and then register those services in the manifest. But, it's not quite perfect. In particular, these two recommended AndroidManifest.xml service entries do not contain any special permissions:
<service android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
and so the linter says:
Exported services (services which either set exported=true or contain an intent-filter and do not specify exported=false) should define a permission that an entity must have in order to launch the service or bind to it. Without this, any application can use this service.
Should I just add this attribute to each service tag and be done with it
tools:ignore="ExportedService"
or is there a better approach in this situation? I mean, is it safe to expose these particular Firebase derived services like this?

You ask: ...is it safe to expose these particular Firebase derived services like this? It is if you trust the comments in the manifest files for these services.
In Android Studio, open your app's AndroidManifest.xml file. At the bottom of the window, select the tab for Merged Manifest. Scroll to find the entry for FirebaseMessagingService. Double-click on the line that contains the service name. The manifest file for the service should open and you will see this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.google.firebase.messaging">
<uses-sdk android:minSdkVersion="14"/>
<application>
<!-- FirebaseMessagingService performs security checks at runtime,
no need for explicit permissions despite exported="true" -->
<service android:name="com.google.firebase.messaging.FirebaseMessagingService" android:exported="true">
<intent-filter android:priority="-500">
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
</application>
</manifest>
Note the comment: FirebaseMessagingService performs security checks at runtime, no need for explicit permissions despite exported="true"
You can do the same for FirebaseInstanceIdService and see the same comment.
If you trust the comments (I do), you can safely ignore the lint warnings or disable the checks.

<service android:name=".java.MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
Based on the official code sample, it's safe to set exported=false

Overriding push notification in BroadcastReceiver (PushBots)?

migrating from Parse I got stuck by not being able to override PushBots notification creation code like I used to do with getNotification function in ParsePushBroadcastReceiver. My project needs multiline and separate push notifications, but PushBots default behavior is to show single line and group notifications by application.
I tried canceling notification in the onReceive function of BroadcastReceiver (PBConstants.EVENT_MSG_RECEIVE event), so I could create & display my own push, but I don't know notification ID and CancelAll() didn't work (also would be a bad idea).
Pushbots.sharedInstance() does have a setNotificationBuilder function, which accepts PBGenerate object, but I have no idea how to construct it properly and if this actually would help my case.
Couldn't find any documentation & get a response from support yet, so asking here if maybe someone knows a solution or a way to workaround this issue.
Here's how receivers are defined in AndroidManifest.xml
<receiver
android:name="com.pushbots.google.gcm.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" />
<category android:name="com.my.app" />
</intent-filter>
</receiver>
<receiver android:name="com.my.app.MyPushReceiver" />
<service android:name="com.pushbots.push.GCMIntentService" />
Thank you in advance!

How can I get data or title from receiving notifications?

I create simple "ParseStarterProject" as default of parse.com project. It works. I send notification from one device to other device successfully via setchannel method.
But the problem is I do not use receiver class(I do not know how can I use that) so when a notification comes I need to get its message ? it is possible? or if I use set data can I get its data ?
I use this code to send message:
ParsePush push = new ParsePush();
String yourMessage = "Selam from LG G2";//I want to get this message from other device?
push.setChannel("device2");
push.setMessage(yourMessage);
//push.setData("exampledata"); if I use this can I get this data from other device?
push.sendInBackground();
my manifest file:
<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>
<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.starter" to match your app's package name.
-->
<category android:name="com.parse.starter" />
</intent-filter>
</receiver>
thanks in advance

Create a class that extends BroadcastReceiver, here we call it MyCustomReceiver. Declare the usage of this receiver in your manifest:
<receiver android:name="com.example.MyCustomReceiver" android:exported="false">
<intent-filter>
<action android:name="com.example.UPDATE_STATUS" />
</intent-filter>
</receiver>
I'm not sure what you mean by you have problems with "MyCustomReceiver class on the main activity", in your comment to #kingspeech's answer.
In the worst case, you can create your own Receiver which extends the ParseBroadcastReceiver (and reference the extended class in the manifest). Then it should work by default, but you'll be able to hook into onReceive(Context, Intent)

As Parse tutorial directs, you ca use JSONObject to set data and you can put whatever you want.
Then when you receive Push notification you can have a access to read the previously prepared JSONObject. Please look at the Android tutorial https://parse.com/docs/push_guide#options/Android.
Hope this helps,
Regards.

Permission for services

i have a service in one application and i want to use that service in one more application.so inoder to start or stop or bind with the service should i need to set any permission?if yes what are the permissions?

#Durga
first of all you have to make one services class for example TestService.java
(1)TestServices.java
now you have to require for permission in menifest.xml
<service
android:name=".TestService"
android:enabled="true" />
<receiver android:name="com.yourpackage.AutoStart" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
now you have to call your services in any activity.
in my case i used receiver to start services in when device is first Boot.
