android - Android RuntimeException: Canvas: 试图绘制太大(108712800bytes) 位图

Question

在显示我的启动活动并重定向到下一个活动后，在显示下一个活动后它会崩溃。我试图删除启动画面可绘制图像，但没有帮助。我还尝试记录以查看它在哪里崩溃，我看到它创建了下一个活动，将 WebView 加载到其中，并且在 SplashActivity 的 onDestroy() 之后它崩溃了。这里真正值得注意的是，它只在小于 28 和 28 及更高版本的 Android API 上崩溃，它可以正常工作。这是我的飞溅活动：

Answer 1

我已经通过在我的 AndroidManifest 文件中设置解决了这个问题android:hardwareAccelerated="false"，并且为了更快、更流畅的图像渲染，如果 Android 版本高于 27，我已经在我的基本活动中以编程方式将其更改为 true。我希望我帮助了某人:)

更新 很抱歉没有更新答案。android:hardwareAccelerated="false" 标志帮助我避免了上述崩溃，但这只是一种解决方法，它在应用程序中产生了一些其他问题。导致问题的真正原因实际上是 NestedScrollView。起初将 android:transitionGroup="true" 放入其中，使该应用程序可以在某些设备上运行，但问题仍然存在。所以最终的解决方案是去掉 NestedScrollView。我发现它在 SwipeRefreshLayout 或 NestedScrollView 内的 WebView 中的某个地方（我不确定，因为它是很久以前的）可能会导致麻烦。希望这有帮助！
