我为 Android Studio(Google Android 项目)构建了 Unity 项目。我在 Android Studio 中打开了它。包括Firebase 崩溃。进行测试以检查异常。在日志中:

Error sending crash report
bkz: Server did not receive report: Origin Error message: Invalid crash stacktrace or minidump.

我如何解决它?

最终我找到了这个问题的最初原因并解决了它。

在 logcat 中我们可以看到 Firebase 初始化在 Unity 之前进行。UncaughtExceptionHandlerUnity 用它自己的替换了 Firebase 的实例。UnityThrowable通过添加有关 Unity 版本的信息进行修改。它以某种方式破坏了堆栈跟踪。在此之后Throwable传递给先前注册的异常处理程序(Firebase)。你可以看到invalid stacktrace消息。

这是解决方法:

在您的第一个场景中,使用以下代码添加脚本:

void Awake() {
    #if UNITY_ANDROID && !UNITY_EDITOR
    using (AndroidJavaClass helper = new AndroidJavaClass ("com.yourcompany.UncaughtExceptionHelper")) {
        helper.CallStatic ("restore");
    }
    #endif
}

然后将此类添加到您的 Android Studio 项目中:

UncaughtExceptionHelper.java

package com.yourcompany;

import android.util.Log;

import java.lang.reflect.Field;

public class UncaughtExceptionHelper {
    private static final String LOG_TAG = UncaughtExceptionHelper.class.getSimpleName();

    public static void restore() {
        try {
            Thread.UncaughtExceptionHandler defaultHandler = Thread.getDefaultUncaughtExceptionHandler();

            if (defaultHandler.getClass().getName().startsWith("com.unity3d.")) {
                for (Field f : defaultHandler.getClass().getDeclaredFields()) {
                    f.setAccessible(true);

                    Object possibleHandler = f.get(defaultHandler);
                    if (possibleHandler instanceof Thread.UncaughtExceptionHandler) {
                        Thread.setDefaultUncaughtExceptionHandler((Thread.UncaughtExceptionHandler) possibleHandler);

                        Log.i(LOG_TAG, "restore " + possibleHandler + " instead of " + defaultHandler);
                        return;
                    }
                }
            }
        } catch (Throwable ex) {
            Log.wtf(LOG_TAG, ex);
        }
    }
}

一起构建它,现在发现logcat输出:
