请求权限READ_SMS后,包安装程序在Android M中崩溃

概述我有一个试图访问的Login Fragment(TelephonyManager)getActivity().getSystemService(Context.TELEPHONY_SERVICE);这适用于Lollipop 5.1之前的设备.当我在Marshmallow 6.01中尝试它时,它显示了安全性异常.所以我从 android docs添加了代码来请求运行时权限.这是代码 int perm 我有一个试图访问的Login Fragment(TelephonyManager)getActivity().getSystemService(Context.TELEPHONY_SERVICE);这适用于Lollipop 5.1之前的设备.当我在Marshmallow 6.01中尝试它时,它显示了安全性异常.所以我从 android docs添加了代码来请求运行时权限.这是代码

int permissionCheck = ContextCompat.checkSelfPermission(getActivity(),Manifest.permission.READ_SMS);    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {        // Should we show an explanation?        if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),Manifest.permission.READ_SMS)) {            // Show an expanation to the user *asynchronously* -- don't block            // this thread waiting for the user's response! After the user            // sees the explanation,try again to request the permission.        } else {            // No explanation needed,we can request the permission.            ActivityCompat.requestPermissions(getActivity(),new String[]{Manifest.permission.READ_SMS},REQUEST_SMS);            // REQUEST_SMS is an            // app-defined int constant. The callback method gets the            // result of the request.        }    }else {        tMgr = (TelephonyManager) getActivity().getSystemService(Context.TELEPHONY_SERVICE);    }

现在我的应用程序启动,很快我的软件包安装程序崩溃了.这是日志

我认为当应用程序尝试显示用于请求权限的UI时,程序包安装程序会崩溃.
我已经添加了< uses-permission androID：name =“androID.permission.READ_SMS”/>在我的清单中

解决方法 您已将READ_SMS清单权限限制为API 22及更低版本.

<uses-permission androID:name="androID.permission.READ_SMS" androID:maxsdkVersion="22" />

正如我在评论中提到的,除了运行时请求之外,Marshmallow及以上版本仍然需要此清单权限.从权限元素中删除maxsdkVersion属性.
