预期

预计MoPubRecyclerAdapter将使用已定义的RecyclerView来对本机Facebook ConstraintLayout单元进行膨胀。

已观察

错误从Facebook原生广告创建的MoPubRecyclerAdapter的{{1}}间歇崩溃。 MoPub SDK forum和MoPub Android Mediation GitHub存储库中已注意到此问题。

尝试的解决方法

库版本已更新，其中MoPub SDK已更新为implementation("com.mopub:mopub-sdk-native-static:5.11.1@aar") { transitive = true } implementation("com.mopub:mopub-sdk-native-video:5.11.1@aar") { transitive = true } implementation 'com.facebook.android:audience-network-sdk:5.1.0' implementation 'com.mopub.mediation:facebookaudiencenetwork:5.1.0.0' implementation 'com.flurry.android:ads:12.1.0@aar' implementation 'com.flurry.android:analytics:12.1.0@aar' implementation 'com.mopub.mediation:flurry:11.4.0.0'，Facebook受众网络已更新为5.12.0，Facebook中介已更新为5.8.0。将确定是否可以解决上述崩溃。

5.8.0.0

Answer 1

使用`RelativeLayout`代替`ConstraintLayout`

正如MoPub的工程师在此GitHub issue中指出的那样，Facebook中介尚不兼容ConstraintLayout。

AdChoices图标的XML视图（ID为native_ad_choices_relative_layout）必须为RelativeLayout，这是因为4.99.0+版本的Facebook Audience Network SDK进行了内部更改。适配器在这里需要RelativeLayout。

之前

    <androidx.constraintlayout.widget.ConstraintLayout
        android:id="@+id/native_ad_choices_relative_layout"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:gravity="left"
        app:layout_constraintBottom_toBottomOf="@id/native_cta"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="@id/native_cta" />

之后

    <RelativeLayout
        android:id="@+id/native_ad_choices_relative_layout"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:gravity="left" />
