Question

我在我的应用程序中使用Facebook Conceal v2.0.1库，有时当我尝试解密图像时，我得到以下本机崩溃：

我有没有办法在Android端捕获该异常？

进入他们的代码似乎他们试图发送一个Android异常，但它在第一行崩溃。

#ifndef FBJNI_NO_EXCEPTION_PTR
local_ref<JThrowable> getJavaExceptionForCppException(std::exception_ptr ptr) {
  FBASSERT(ptr);  <------- CRASHES OVER HERE
  local_ref<JThrowable> previous;
  auto func = [&previous] (std::exception_ptr ptr) {
    auto current = convertCppExceptionToJavaException(ptr);
    if (previous) {
      current->initCause(previous);
    }
    previous = current;
  };
  denest(func, ptr);
  return previous;
}
#endif

我确实遵循了逻辑，似乎只有在发布时，有时库无法加载。因此经过大量的挖掘和测试后发现，我的问题的当前解决方案是添加到发布proguard文件-keep class com.facebook.** { *; }。有关here的更多信息。
