我正在将 Skobbler 更新到 2.5.2 版以修复 libpng Google Play 警告（我也尝试更新到 3+ 版），但更新后导航停止正常工作。
在onRouteCalculationCompleted之后，我使用SKRouteManager.getInstance().getAdviceList()检查建议列表 并接收有效建议。
SKRouteAdvice [adviceID=0, timeToDestination=261, distanceToDestination=1234, timeToAdvice=0, distanceToAdvice=0, streetName=Rua Barao do Abiaí, visualAdviceFile=/data/user/0/myapp/files/SKMaps//Advisor/Visual/104962/1.png, advicePosition=[-35.886744260787964,-7.215477737837522], adviceInstruction=Now turn left then turn right , audioFilePlaylist=[now, turn_left, then_open, turn_right], currentStreetType=RESIDENTIAL, currentStreetFCClass=FC3, streetDirection=DIRECTION_LEFT]
但是，在导航时，建议是无效的，如下所示：
onUpdateNavigationState SKNavigationState [adviceID=-1, currentSpeed=5.304781188371101E-58, currentSpeedLimit=0.0, countryCode=, lastAdvice=false, showSignPost=false, currentAdviceCurrentStreetName=, currentAdviceNextStreetName=, currentAdviceCurrentOsmStreetType=UNDEFINED, currentAdviceNextOsmStreetType=UNDEFINED, currentAdviceDistanceToAdvice=-738480304, currentAdviceTimeToDestination=-738962832, currentAdviceDistanceToDestination=-738480656, currentAdviceVisualAdviceFile=, currentAdviceAudioAdvices=[None], currentAdviceExitNumber=, nextAdviceCurrentStreetName=, nextAdviceNextStreetName=, nextAdviceDistanceToAdvice=-738854288, nextAdviceVisualAdviceFile=, nextAdviceCurrentOsmStreetType=UNDEFINED, nextAdviceNextOsmStreetType=UNDEFINED, distanceToDestination=0.0, firstCrossingDescriptor=SKCrossingDescriptor [crossingType=0, routeAngle=0.0, turnToRight=false, directionUK=false, allowedRoutesAngles=null, forbiddenRoutesAngles=null], secondCrossingDescriptor=SKCrossingDescriptor [crossingType=0, routeAngle=0.0, turnToRight=false, directionUK=false, allowedRoutesAngles=null, forbiddenRoutesAngles=null], adviceInstruction=, viaPointsInfo=null, isLastVisualAdvice=false, currentStreetDirection=DIRECTION_INVALID, nextStreetDirection=DIRECTION_INVALID]
为了检查建议列表是否仍然有效，我在开始导航之前添加了一个日志代码，应用程序崩溃并出现以下错误：

PS：我的代码与 Skobbler 的演示项目非常相似。
其他人有同样的问题吗？
