android - Why has the READ_PHONE_STATE permission been added?

Question

In the latest beta version I just published to the Play Store, I notice that the READ_PHONE_STATE has been added since the previous version.

I haven't added this myself. All I can recall doing since the previous version is using v9.6.0 of various play-services libraries (was v9.4.0):

compile 'com.google.android.gms:play-services-location:9.6.0'
compile 'com.google.android.gms:play-services-places:9.6.0'
compile 'com.google.android.gms:play-services-auth:9.6.0'

Would this have done it? I can't see it documented. Can I get rid of the permission?

And I've ensured that all the of the libraries I'm using match the main app, as per this answer... makes no difference in my case.

EDIT

OK based on this article, I've delved into my log output to find:

ADDED from [Meteogram:jobdispatcher:unspecified] C:UsersMeAndroidStudioProjectsMeteogramappuildintermediatesexploded-aarMeteogramjobdispatcherunspecifiedAndroidManifest.xml:37:25-84 android:uses-permission#android.permission.READ_PHONE_STATE

But nothing has changed in the jobdispatcher library (which I imported into my project as a gradle module) since the last version.

EDIT2

Here is a bit more from that log, and my feeling is that maybe it is due to the play-services library version as suspected?

activity#com.google.android.gms.common.api.GoogleApiActivity

The targetSdkVersion < 4 matches with the other answer linked above, but is there anything I can do in this situation, since the play-services library is not mine?

EDIT3

I found an answer... rather than delete this question I'll leave it up, with solution, in case it's useful for others (and in case someone else has a better solution!)

EDIT4

Looks like it has been fixed in 9.6.1.

Answer 1

I eventually found this, which reports the same issue. One workaround is mentioned in Answer #3, which is to remove the permission "manually" (my assumption is that the permission is only required for very early Android versions, which is OK for me since my minSdk is 16):

<manifest ...
    xmlns:tools="http://schemas.android.com/tools"
    ... >

<uses-permission
    android:name="android.permission.READ_PHONE_STATE"
    tools:node="remove" />
