昨天我设置了目标并将编译SDK设置为23 API级别。当我在带有预览版Android M(MPA441)的Nexus 9上启动应用程序时,应用程序崩溃,并显示以下“SecurityException”:

有人知道为什么通过Android Studio安装应用程序时,默认情况下禁用权限吗?避免这种崩溃的正确方法是什么,也许有一种方法可以检查目标权限是否启用,只有在启用时应用程序才能使用某些特定的设备API(读取电话状态、联系人和其他权限)?在互联网上,我只找到了与此问题相关的mention 1,但我没有找到任何清晰的解释:这是Android M中的错误还是开发人员不能理解如何以安全的方式使用权限!?我也阅读了这个post,但是要求用户进入设置并启用应用程序的权限的方法看起来很奇怪,不太友好。我猜如果用户从Google Play安装应用程序,一切都会很好,因为他明确地申请了所请求的权限,但我需要确认一下。
