当我尝试更新Pushwoosh库中的Pushwoosh应用程序时，我收到错误。我已经在 Gradle 中更新了它。

我在哪里得到错误
Pushwoosh.getInstance().registerForPushNotifications();
从Pushwoosh Github 复制响应：
这不是Pushwoosh SDK的错误。这是Android应用程序环境中多处理器应用程序的特殊性。
当您集成分析工具(如LeakCanary，AppMetrica等)时，这些库会为自己启动一个新过程。在此过程中创建应用的新实例。但是您不需要在这个单独的进程中侦听推送，因此默认情况下您不应该在Application.onCreate()中调用registerForPushNotifications()。
因此，有两种可能的解决方案：
不要在里面打电话给
registerForPushNotificationsApplication.onCreate()如果要在 Application.onCreate() 中调用 registerForPushNotifications ，则应在应用程序的主进程中执行检查：
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;
}
}
