Collections.sort造成java.lang.SecurityException异常：要求READ_PHONE_STATE

我得到下面的崩溃在这行代码：Collections.sort造成java.lang.SecurityException异常：要求READ_PHONE_STATE

pkgMrg_global = getActivity().getPackageManager(); 
apps = pkgMrg_global.getInstalledApplications(0); 
//GETTING CRASH AT LINE BELOW 
Collections.sort(apps, 
         new ApplicationInfo.DisplayNameComparator(
           pkgMrg_global));

什么我不明白是怎么Collections.sort导致这个Caused by: java.lang.SecurityException: Requires READ_PHONE_STATE: Neither user 10157 nor current process has android.permission.READ_PHONE_STATE？

上添加权限你的清单文件。 – MetaSnarf

错误的原因是代码 – MetaSnarf

上的'.getInstalledApplications（0）;'或new'ApplicationInfo.DisplayNameComparator（pkgMrg_global）'是的，但我不明白为什么必须这样做。我没有使用任何电话功能（只是对应用程序列表进行排序），所以不应该需要它。从用户的手机得到这个报告，所以不能再现自己。 – user1406716

此权限添加到您的Android清单

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

按照谷歌文档here 票据上写着：注：如果同时你的minSdkVersion和targetSdkVersion值设置为3或更低时，系统会隐式授予您的应用程序此权限。如果您不需要此权限，请确保您的targetSdkVersion为4或更高。

防护等级：危险

如果是这样，你需要添加的权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

常数值： “android.permission.READ_PHONE_STATE”
