在前景中的Unity应用程序崩溃，并点击从相同的应用程序创建的通知

Question

我正在一个Unity应用程序。当它处于前台并且用户从通知栏中点击通知视图并且正在触发挂起的意图时，它会崩溃。应用程序崩溃，logcat中没有明确的堆栈跟踪可用。

什么程序崩溃的过程中，我可以看到的是如下

I/WindowState: WIN DEATH: Window{26cb4ca u0 com.aman.unitytest/com.unity3d.player.UnityPlayerProxyActivity} 
10-14 16:28:57.234 1796-2360/? 

下面是logcat的一块，当用户点击通知：

得到了问题，并使其可行。以下是现在用于pendingIntent通知的内容。

launchIntent.setFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED | Intent.FLAG_ACTIVITY_NEW_TASK); 

而在使用unity时，它们是AndroidManfiest.xml中提到的不推荐使用的Launcher，如下所示。停止使用它了。

com.unity3d.player.UnityPlayerProxyActivity 

请改用您的AndroidManifest中的以下条目以使其正确。

<activity 
      android:name="com.unity3d.player.UnityPlayerActivity" 
      android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" 
      android:label="@string/app_name" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 

由于ProxyActivity下面在其的onCreate（）。因此，无论您在pendingIntent中添加的任何标志都没有关系。此代理活动将忽略所有内容。

paramBundle = new String[] { "com.unity3d.player.UnityPlayerActivity", "com.unity3d.player.UnityPlayerNativeActivity" }; 
    copyPlayerPrefs(this, paramBundle); 
    try 
    { 
     int i = Build.VERSION.SDK_INT >= 9 ? 1 : 0; 
     paramBundle = Class.forName(paramBundle[0]); 
     (paramBundle = new Intent(this, paramBundle)).addFlags(65536); 
     Bundle localBundle; 
     if ((localBundle = getIntent().getExtras()) != null) { 
     paramBundle.putExtras(localBundle); 
     } 
     startActivity(paramBundle); 
     return; 
    } 
    catch (ClassNotFoundException localClassNotFoundException) {}finally 
    { 
     finish(); 
    }
