在 onFilterTouchEventForSecurity 处获取 NullPointerException [英] Getting NullPointerException at onFilterTouchEventForSecurity

问题描述

我已经构建了应用程序，我在其中集成了 YouTube API，它运行良好，没有任何崩溃，但在 Fabric 上我检查了一些崩溃，这是 ipf.onFilterTouchEventForSecurity.这是崩溃的完整日志:

我知道这个问题不是因为代码，但我需要防止崩溃.

I know that this issue is not because of code but I need to prevent crashing.

以下是我遇到问题的设备列表:

推荐答案

我无法重现它，但您可以尝试以下几点:

I am not able to reproduce it but there are several things you can try:

如果可能，请尝试添加 android:filterTouchesWhenObscured=false 作为澄清 建议 来自文档:

If possible try adding android:filterTouchesWhenObscured=false as pellucide suggested from the docs:

指定当视图的窗口被遮挡时是否过滤触摸通过另一个可见的窗口.设置为 true 时，视图将不会接收每当 Toast、对话框或其他窗口出现在视图的窗口.有关更多信息，请参阅查看安全文档详情.

Specifies whether to filter touches when the view's window is obscured by another visible window. When set to true, the view will not receive touches whenever a toast, dialog or other window appears above the view's window. Refer to the View security documentation for more details.

可以是布尔值，例如true"或false".

May be a boolean value, such as "true" or "false".

否则，您可以尝试覆盖根视图的调度方法并在那里放置一个 try catch，您可以将其用作 自定义组件(如果需要).

Otherwise, you can try overriding the dispatch method of your root view and place a try catch there, you can use it as a custom Component if needed.

@Override
void dispatchTouchEvent(MotionEvent event){
    try{
        super.dispatchTouchEvent(event);
    }
    catch (Exception e){
        e.printStackTrace();
    }
}
