我在下面的代码行中遇到了崩溃：
pkgMrg_global = getActivity().getPackageManager();
apps = pkgMrg_global.getInstalledApplications(0);
//GETTING CRASH AT LINE BELOW
Collections.sort(apps,
new ApplicationInfo.DisplayNameComparator(
pkgMrg_global));
我不明白Collections.sort如何导致Caused by: java.lang.SecurityException: Requires READ_PHONE_STATE: Neither user 10157 nor current process has android.permission.READ_PHONE_STATE？

根据谷歌文档here 说明说 注意：如果您的minSdkVersion和targetSdkVersion值都设置为3或更低，系统会隐式授予您的应用此权限。如果您不需要此权限，请确保您的targetSdkVersion为4或更高。
保护等级：危险
如果需要，您需要添加权限
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
常量值：“android.permission.READ_PHONE_STATE”

将此权限添加到您的Android清单
