我爲Android Studio(Google Android項目)構建了Unity項目。我在Android Studio中打開了它。包括Firebase崩潰。進行測試以檢查異常。在原木中:無效的崩潰堆棧跟蹤或小型轉儲

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

我該如何解決?

我有同樣的問題:Unity +本機Firebase庫。我已通過此表單報告了此錯誤:https://firebase.google.com/support/contact/bugs-features/我建議您也這樣做。這就是我們現在可以做的。 –

最終我找到了這個問題的最初原因並解決了它。

在logcat中,我們可以看到Firebase初始化在Unity之前。 Unity會自行替換Firebase的UncaughtExceptionHandler實例。 Unity會通過添加關於Unity版本的信息來修改Throwable。它以某種方式破壞堆棧跟蹤。在此之後Throwable傳遞給先前註冊的異常處理程序(Firebase)。你可以看到invalid stacktrace消息。

這裏的解決方法:

在你的第一個場景該代碼添加腳本:

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

然後將該類添加到您的Android Studio項目:

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); 
     } 
    } 
} 

建立在一起,現在發現logcat輸出:
