Code samples & details

I launched the app in debug mode and encountered the following error:
`{"error":{"message":"Invalid access token signature.","type":"OAuthException","code":190,"fbtrace_id":"AfitjEP1vLloVIvZq1tsPYd"}}`

Request:                                                                                                     Id:	4                                                                                                    URL:	https://graph.facebook.com/v16.0/app/mobile_sdk_gk?access_token=1234567891011123%7C1234567891011123%7Ci-ZTjvShHEt8NdXTRfI8yrTvP6w&fields=gatekeepers&format=json&sdk_version=17.0.2&sdk=android&platform=android                                                                                                   Method:	GET                                                                                                     User-Agent:	FBAndroidSDK.17.0.2                                                                                                   Content-Type:	application/x-www-form-urlencoded

As I can see, the access_token in this case duplicates the app_id:
app_id | app_id | secret

According to the documentation, it should follow this format:
app_id | secret

If you remove the duplication of the app ID from the link:
https://graph.facebook.com/v16.0/app/mobile_sdk_gk?access_token=1234567891011123%7C1234567891011123%7Ci-ZTjvShHEt8NdXTRfI8yrTvP6w&fields=gatekeepers&format=json&sdk_version=17.0.2&sdk=android&platform=android

and leave the correct format:
https://graph.facebook.com/v16.0/app/mobile_sdk_gk?access_token=1234567891011123%7Ci-ZTjvShHEt8NdXTRfI8yrTvP6w&fields=gatekeepers&format=json&sdk_version=17.0.2&sdk=android&platform=android

and then open it in the browser, everything works as it should.

I double-checked how I specify the client_token in my app, and it's in the correct format. I generated it using:
https://graph.facebook.com/oauth/access_token?client_id=app_id&client_secret=app_secret&grant_type=client_credentials

I tried using different versions of the library starting from 7.1.0, but I always get the same result.

Integration of the library in the application according to the documentation:
<meta-data
    android:name="com.facebook.sdk.ApplicationId"
    android:value="@string/facebook_app_id" />
<meta-data
    android:name="com.facebook.sdk.ClientToken"
    android:value="@string/fb_client_token" />
<meta-data
    android:name="com.facebook.sdk.AutoLogAppEventsEnabled"
    android:value="true"/>
<meta-data
    android:name="com.facebook.sdk.AutoInitEnabled"
    android:value="true"/>

Gradle:
implementation("com.facebook.android:facebook-android-sdk:17.0.2")

In Activity:
if (FacebookSdk.isInitialized()) {
    FacebookSdk.setIsDebugEnabled(true);
    FacebookSdk.addLoggingBehavior(LoggingBehavior.APP_EVENTS);
    FacebookSdk.addLoggingBehavior(LoggingBehavior.REQUESTS);
    FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_RAW_RESPONSES);
}

If I use just the app_secret in the client_token, everything works. Perhaps that's how it's supposed to be. It turns out I was wrong. The issue can be closed
