【问题描述】：
我正在制作一个审核应用程序，我必须从单选按钮和 14 个检查点的图像中收集是/否。
该应用程序在我的具有 Android 10 设备的设备上运行良好，但是在以任何随机方式收集 4-6 张图像并在相应的 Imageview 上显示它们并在 String 中收集 Byte[] 之后在某些设备上进行测试时，例如在某些 Nougat 设备中变量应用程序崩溃日志中也没有错误（现在通过调试器找到它，见下文）。看看相机的代码。应用程序在返回活动时单击照片后崩溃。
public void ClickImageFromCamera(String code) {
Intent CamIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

【问题讨论】：
-
“应用程序崩溃，日志中也没有错误。” 你确定吗？ “当应用程序返回活动时单击照片后崩溃。” 然后您可以逐步调试
onActivityResult()方法，查看究竟是什么崩溃以及变量值是什么，即@例如 987654328@。 -
确定在调试器 java.lang.OutOfMemoryError 中发现错误：无法分配 14745612 字节分配，4194304 可用字节和 8MB 直到 OOM
-
在编辑大位图时听起来像是个问题。 Android 文档可能会在 managing bitmaps 上提供一些相关提示。
-
Camera Intent Crashes in some Device如果这是您的意图，那么您应该只发布该代码。但似乎只有在调用 onActivityResult 并且您执行各种代码之后。请用真正的问题更新您的主题。 -
你在onActivityResult中有太多的可能性。一个就足够了。请删除所有其他人。为什么 previewCapturedImage 是 previewCapturedImage2 ？只发布导致问题的那个。发布一个最小的例子。
