当我尝试在Pushwoosh库中更新pushwoosh应用程序时出现错误。我已在Gradle中更新了它。

我收到错误

        Pushwoosh.getInstance().registerForPushNotifications();

1 个答案:

答案 0 :(得分:0)

在此处复制Pushwoosh Github的回复:

这不是Pushwoosh SDK的错误。这是Android应用环境中多处理器应用程序的特性。

当您集成LeakCanary,AppMetrica等分析工具时,这些库会为自己启动一个新流程。在此过程中创建了一个新的应用程序实例。但是你不需要在这个单独的过程中监听推送,所以默认情况下你不应该在registerForPushNotifications()内调用Application.onCreate()

因此有两种可能的解决方案:

  • 不要在registerForPushNotifications

  • 内拨打Application.onCreate()
  • 如果要在Application.onCreate()中调用registerForPushNotifications,则应该检查应用程序的主进程:

List < ActivityManager.RunningAppProcessInfo > runningAppProcesses = ((ActivityManager) getSystemService(Context.ACTIVITY_SERVICE)).getRunningAppProcesses(); if (runningAppProcesses != null && runningAppProcesses.size() != 0) { for (ActivityManager.RunningAppProcessInfo runningAppProcessInfo: runningAppProcesses) { boolean isCurrentProcess = runningAppProcessInfo.pid == android.os.Process.myPid(); boolean isMainProcessName = getPackageName().equals(runningAppProcessInfo.processName); if (isCurrentProcess && isMainProcessName) { Pushwoosh.getInstance().registerForPushNotifications(...); break; } } }
