昨天我设置了目标并将sdk编译为23 API级别。当我使用预览Android M(MPA441)在Nexus 9上启动应用程序时,该应用程序崩溃并出现以下 SecurityException :

当我通过Android Studio安装应用时,有人知道为什么默认情况下对新安装的应用禁用了权限吗?避免这种崩溃的正确方法是什么,也许有办法检查启用或不启用目标权限,并且只有在启用时,应用程序应该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,我发现此mention与此问题相关1,但我没有找到任何明确的解释:Android M中的错误或开发人员无法理解以安全的方式使用权限!?此外,我已经阅读了这个post,但是当用户进入设置并启用应用看起来很奇怪而且不方便用户的权限时,我会采用这种做法。我想如果用户从Google Play安装应用程序,一切都会好的,因为他明确要求申请权限,但我需要确认。
答案 0 :(得分:8)
您可以在此处找到如何在运行时请求权限。
