Question

我为Android Studio（Google Android项目）构建了Unity项目。我在Android Studio中打开了这个。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.

我该如何解决？

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。 Unity取代了Firebase的UncaughtExceptionHandler实例。 Unity通过添加有关Unity版本的信息来修改Throwable。它会以某种方式破坏堆栈跟踪。在此Throwable传递给先前注册的异常处理程序（Firebase）之后。您可以看到invalid stacktrace消息。

此处有解决方法：

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Android Studio项目中：

<强> 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：

无效的崩溃堆栈跟踪或小型转储
