NullPointerException: onTouchEvent() HERE Maps Android SDK

Question

我的崩溃报告系统报告了许多NullPointerExceptions，这似乎与 HERE Maps Android SDK 有关。它没有从我的代码中给我任何特定的行号，所以我不确定如何调试和解决问题。我无法在我自己的设备上复制它。有人有什么建议吗？

建议您联系 HERE 地图支持。这是 SDK 代码中的一个错误。

Answer 2

我之前也遇到过同样的问题。我的问题是在android5.0之前没有错误系统会在android6.0之后挂起。应用检测到android6.0权限是动态的后，问题解决后我在代码中添加了动态应用权限。不知道这个方案对你有用吗？
