尝试打开应用选择器以显示PDF时，我的应用崩溃。崩溃似乎在应用程序依赖库中定义的类中。奇怪的是，类 T4PushAuthentication 显然与调用无关。它仍然是呼叫活动的成员 这是导致崩溃的代码片段：
Intent target = new Intent(Intent.ACTION_VIEW);
Uri fileUri = T4IDAppFileProvider.getUriForFile(activity, activity.getApplicationContext().getPackageName() + ".utils.provider", file);
target.setDataAndType( fileUri, T4Keys.APPLICATION_PDF);
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Intent chooserIntent = Intent.createChooser(target, "Open File");
chooserIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
activity.startActivity(chooserIntent);
执行最后一行代码时发生崩溃。
这是我得到的堆栈跟踪：

编辑：问题似乎是调用活动中的T4PushAuthentication成员类。看起来被调用者序列化了该成员，并且在尝试对其进行反序列化时找不到该类信息。我如何提供此类信息？我想念什么吗？
答案 0 :(得分：0)
我发现了这个错误，实际上是在活动类本身中：它在startActivity成员中有一个重载，该成员将T4PushAuthentication对象包装到了intent中：（
