【中文标题】创建动态链接时，Android 上的 Firebase C++ SDK 因 SIGSEGV 故障地址 0x0 而崩溃

【英文标题】：Firebase C++ SDK on Android Crashes with SIGSEGV fault addr 0x0 when creating dynamic link

【问题描述】：

我们正在为我们的 ios 和 android 游戏使用 Firebase C++ SDK。在 iOS 上，创建动态链接非常有效，但在 Android 上，我们遇到了崩溃，即使经过无数小时的各种尝试，我们也无法解决。

这是导致崩溃的代码：

  std::string appBundleId = getAppBundleIdentifier();

   firebase::dynamic_links::IOSParameters ios_parameters(appBundleId.c_str());

   firebase::dynamic_links::AndroidParameters android_parameters(appBundleId.c_str());

   firebase::dynamic_links::DynamicLinkComponents components(
           "https://example.com/", "abc123.app.goo.gl");
   components.android_parameters = &android_parameters;
   components.ios_parameters = &ios_parameters;

   // This log shows that the app is not nullptr
   MLLOG("Firebase Instance %s", firebase::App::GetInstance()->name());

   // The next line crashes
   firebase::dynamic_links::GeneratedDynamicLink longLink = firebase::dynamic_links::GetLongLink(components);

这是堆栈跟踪，我们通过 adb logcat 获得：

以防万一这可能是问题的一部分，我们的 firebase 应用似乎已成功创建 - 我们通过 onCreate 的本机调用来完成：

JNIEXPORT void JNICALL Java_org_cocos2dx_cpp_AppActivity_onCreate(JNIEnv* env, jclass, jobject aMainActivity)

    MLLOG("java_org_cocos2dx_cpp_AppActivity_onCreate called");
     firebase::AppOptions appOptions;
    _firebaseApp = firebase::App::Create(appOptions, env, aMainActivity);
    auto app = firebase::App::GetInstance();

    // Both log the same pointer here
    MLLOG("FIREBASE APP INIT %p AppGetInstance %p", _firebaseApp, app);

【参考方案1】：

您是否尝试过使用初始化您的应用程序

::firebase::dynamic_links::Initialize(app, null);

在调用 GetLongLink 之前？
