In the Google Play Console pre-launch report, I the "STABILITY" section, I have this error that I need to fix:

I suspect that this problem might be happening because my Facebook library is too old. In my app/build.gradle I am using this Facebook library:
implementation 'com.facebook.android:facebook-android-sdk:3.23.1'
I am sure it is very old and most likely deprecated in many ways. It still works though, but it might be the cause of this error that I see. Also, I am using this:
dependencies {
...
implementation files('libs/easyfacebookandroidsdk_2.3.jar')
....
}
That Facebook library must be the cause. Any ideas about fixing that NullPointerException that I see in the error? I guess the best should be for me to upgrade those very old Facebook libraries.
The problem was not Facebook. After examining the logs, the real problem was this:

The solution was to go include the following line inside of the <application> section of my AndroidManifest.xml:
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
