[java] onCreate 활동의 java.util.ConcurrentModificationException

Admob 광고 조정을 통해 MoPub를 추가 한 최근 릴리스에서 충돌 로그에 많은 ConcurrentModificationException이 표시됩니다. 그것은 모두 네이티브 코드 인 것 같고 모든 광고 관련 및 Google / Android 관련 라이브러리의 최신 버전을 사용하고 있습니다. 전에 이걸 본 사람 있어요?

BaseActivity의 21 행까지 코드는 다음과 같습니다.

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

RecentGameActivity의 70 번째 줄까지의 코드입니다.

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