为何getContext()有时会回归null？我将上下文LastNewsRVAdapter.java作为参数传递.但LayoutInflater.from(context)有时会崩溃.我在游戏机上收到一些崩溃报告.以下是崩溃报告.

java.lang.NullPointerException
com.example.adapters.LastNewsRVAdapter.<init>

java.lang.NullPointerException:

这是LastNewsRVAdapter.java构造函数.

public LastNewsRVAdapter(Context context, List<LatestNewsData> 
    latestNewsDataList, FirstPageSideBanner sideBanner) {
    this.context = context;
    this.latestNewsDataList = latestNewsDataList;
    inflater = LayoutInflater.from(context);
    this.sideBanner = sideBanner;
}

这是onCreateView …

致命异常显示在Firebase仪表板中。但非致命异常未显示在Firebase crashlytics和 中Firebase crash reporting。在非致命崩溃后，我重新启动了应用程序几次，但在Firebase dashboard. 依赖项是：-

implementation('com.crashlytics.sdk.android:crashlytics:2.9.1@aar') {
    transitive = true
}
implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.google.firebase:firebase-messaging:11.8.0'

以下是非致命异常的代码。

try {
    throw new IndexOutOfBoundsException("Fake IndexOutOfBoundsException");
} catch (Exception e) {
    Crashlytics.logException(e);
}
