尝试打开详细信息活动时意外崩溃

Question

我在材料设计应用程序中遇到了一个奇怪的问题。一些缩略图正在按预期打开和加载详细信息活动，但有些缩略图没有打开，而是发生了崩溃。在此视频中，您可以看到我面临的问题。 我正在附加链接到我的项目ZIP文件链接，我的项目

这是主要活动....

这是我尝试调试时的控制台日志.... 当它工作正常时，控制台日志08/09 20:31:31: Launching app No apk changes detected since last installation, skipping installation of /home/soumyajit/AndroidStudioProjects/MaterialReader/app/build/outputs/apk/debug/app-debug.apk $ adb shell am force-stop lordsomen.android.com.materialreader $ adb shell am start -n "lordsomen.android.com.materialreader/lordsomen.android.com.materialreader.activities.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER -D Connecting to lordsomen.android.com.materialreader Connected to the target VM, address: 'localhost:8601', transport: 'socket'

当它崩溃时，控制台日志是

最大包裹大小不应超过 1mb。在您的应用程序中，它是2.1 Mb。如果不将应用日期传递给下一个活动，则可以尝试在下一个活动中传递项目 ID 并加载数据。否则，您可以缓存列表数据，并且可以在详细信息活动中从本地数据库加载数据。如果您在 android 工作室中看不到崩溃登录，因为它设置为"仅显示选定的活动"。在这种情况下，应用程序关闭，然后这种类型的日志不会显示在 android 工作室中。将其切换到无过滤器，您可以看到所有日志。
