Question

У меня есть ошибка в Android-проекте для WebRTC.

E / AndroidRuntime: FATAL EXCEPTION: main Процесс: com.audiocodes.mv.webrtcclient, PID: 2551 java.lang.RuntimeException: невозможночтобы начать действие ComponentInfo {com.audiocodes.mv.webrtcclient / com.audiocodes.mv.webrtcclient.Activities.SplashActivity}: java.lang.NullPointerException: попытка вызвать виртуальный метод 'java.util.ArrayList com.audiockv.m..useragent.AudioCodesUA.getSessionList () 'для ссылки на пустой объект в android.app.ActivityThread.performLaunchActivity (ActivityThread.java:2325) в android.app.ActivityThread.handleLaunchActivity (ActivityThread.java:2387) в android.read.Activity.access $ 800 (ActivityThread.java:151) на android.app.ActivityThread $ H.handleMessage (ActivityThread.java:1303) на android.os.Handler.dispatchMessage (Handler.java:102) на android.os.Looper.loop(Looper.java:135) в android.app.ActivityThread.main (ActivityThread.java:5254) в java.lang.reflect.Method.invoke (Native Method) в java.lang.reflect.Method.invoke (Method.java:372) в com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run (ZygoteInit.java:903) в com.android.internal.os.ZygoteInit.main (ZygoteInit.java:698) Вызывается: java.lang.NullPointerException: попытка вызвать виртуальный метод 'java.util.ArrayList com.audiocodes.mv.webrtcsdk.useragent.AudioCodesUA.getSessionList ()' для нулевого объектана com.audiocodes.mv.webrtcclient.General.ACManager.getActiveSession (ACManager.java:139) на com.audiocodes.mv.webrtcclient.General.ACManager.isAllredyInActiveCall (ACManager.java:1dioct).General.NotificationUtils.createAppNotification (NotificationUtils.java:33) в com.audiocodes.mv.webrtcclient.Activities.BaseAppCompatActivity.onCreate (BaseAppCompatActivity.java:34) в com.audiocodes.mv.wc.java: 29) на android.app.Activity.performCreate (Activity.java:5990) на android.app.Instrumentation.callActivityOnCreate (Instrumentation.java:1106) at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:2278)

Я думаю, что ошибка здесь. Но я не знаю. Это код.
