需要依赖：
"rxpermissions2" : "com.github.tbruyelle:rxpermissions:0.10.2", "rxerrorhandler2" : "me.jessyan:rxerrorhandler:2.1.1",
注意：
同一时间多次调用无效，如果需要申请多个权限，需要如下public static void all(RequestPermission requestPermission, RxPermissions rxPermissions, RxErrorHandler errorHandler) { requestPermission(requestPermission, rxPermissions, errorHandler, Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.READ_PHONE_STATE, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA); } 如果多个权限申请，
onRequestPermissionFailureWithAskNeverAgainonRequestPermissionFailureonRequestPermissionSuccess可以通过，
if (!permissions.contains(Manifest.permission.WRITE_EXTERNAL_STORAGE))
判断权限是否通过
