Activity onCreate 中的 java.util.ConcurrentModificationException

Question

在最近的一个版本中，我通过 Admob 广告中介添加了 MoPub，我在崩溃日志中看到了一堆 ConcurrentModificationException。这一切似乎都是 native 代码，我使用的是所有广告相关库和 google/android 相关库的最新版本。有人遇到过这个吗？

java.lang.RuntimeException:

这是 BaseActivity 第 21 行代码的样子:

protected void onCreate(Bundle savedInstanceState) {
        supportRequestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
        super.onCreate(savedInstanceState);

这是最近游戏 Activity 第 70 行代码的样子

public class RecentGameActivity extends BaseActivity implements AdapterView.OnItemSelectedListener {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

在我们的例子中，我们只看到崩溃

com.google.firebase:firebase-analytics:17.2.2 

恢复到 17.2.1 已解决问题

如果您使用的是 firebase-core:17.2.2，也会发生这种情况，因为 firebase-analytics 是重新命名的同一个库。考虑到根据官方文档，当前使用 firebase-core 已被弃用 -> https://firebase.google.com/support/release-notes/android#latest_sdk_versions
