Question

我在手机上运行我的应用程序。一切都很完美..但在我检查我的logcat进行调试之后。它告诉我这个错误。

E / HAL：hw_get_module_by_class：模块名称gralloc E / HAL：hw_get_module_by_class：模块名称gralloc

当用户第一次运行应用时，它会显示。它显示了应用程序显示启动画面的时间。我不确定哪个代码会让这件事情发生。所以我会告诉你我的启动代码和我的片段家庭代码。

所以这是我的splasactivity代码：

        Constant.columnWidth = (int) ((jsonUtils.getScreenWidth() - ((Constant.NUM_OF_COLUMNS + 1) * padding)) / Constant.NUM_OF_COLUMNS);

        if(!Constant.isFromNoti) {

            }, 2000);
        } else {

再一次，我确定这里发生了什么。

我从3天前看到此错误，但我检查了我的代码，我不知道这段代码有什么问题。

Answer 1

当您的循环没有终止时会发生这种错误。我也遇到过类似的情况，从字面上看，我花了两天时间才找出问题的根本原因。

我的问题是：

enter image description here

运行上面的代码时，我曾经遇到这种错误 hw_get module_by class _gralloc ... 。

我真的很沮丧，因为我无法找到根本原因，幸运的是，我发现代码的上述部分是主要原因，因为循环永远不会在上述部分终止，并且当我发现问题的主要原因是我将其替换为：

enter image description here

然后，问题解决了。 所以也许您的问题出在循环或类似情况下。

我在logcat hw_get_module_by_class：模块名称gralloc中发现了这个错误
