在Google Play控制台发布前报告的“稳定性”部分中，我需要修复此错误：

我怀疑此问题可能是由于我的Facebook库太旧而发生的。在我的app/build.gradle中，我正在使用此Facebook库：

implementation 'com.facebook.android:facebook-android-sdk:3.23.1'

我确信它已经很老了，很可能在许多方面已被弃用。虽然它仍然有效，但是可能是我看到此错误的原因。另外，我正在使用这个：

dependencies {
    ...
    implementation files('libs/easyfacebookandroidsdk_2.3.jar')
    ....
}

该Facebook库一定是原因。我对在错误中看到的NullPointerException的修复有任何想法吗？我想最好的办法应该是升级那些非常老的Facebook库。

问题不是Facebook。检查日志后，真正的问题是：

解决方案是在我的<application>的{{1}}部分中加入以下行：

AndroidManifest.xml

这在https://developer.android.com/about/versions/pie/android-9.0-changes-28#apache-p上有解释。
