Unity应用在前台，点击来自同一应用程序创建的通知时崩溃

Question

我正在开发一款Unity应用。当应用在前台运行时，用户点击来自通知栏的通知视图并触发待处理意图时，应用会崩溃。在logcat中没有明确的堆栈跟踪可用，但可以看到应用程序崩溃时的情况如下：

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

当用户点击通知时，下面是logcat的片段：

调试你的代码并检查崩溃的原因。仅通过检查日志我们无法提供帮助。 - Maveňツ

嗨，Maven，谢谢您的考虑。但是您能帮我解决如何调试Unity应用程序以检查导致上述问题的原因吗？ - Aman Kumar Aggarwal

Answer 1

我已经解决了问题并使其可行。以下是我现在为通知使用的pendingIntent。

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

当使用Unity时，AndroidManifest.xml中提到了一个已弃用的Launcher，请停止使用它。

com.unity3d.player.UnityPlayerProxyActivity

相反，使用以下条目在AndroidManifest中使其正确。

<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在其onCreate()方法中有以下内容，因此无论您在pendingIntent中添加什么标志都无关紧要。这个代理活动将忽略一切。

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();
    }
