集合.sort导致java.lang.SecurityException:需要READ_PHONE_STATE

Question

我在下面的代码行看到崩溃:

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

我不明白的是Collections.sort是如何导致Caused by: java.lang.SecurityException: Requires READ_PHONE_STATE: Neither user 10157 nor current process has android.permission.READ_PHONE_STATE的?

Answer 1

按照这里的谷歌文档纸条上写着注意:如果你的minSdkVersion和targetSdkVersion的值都设置为3或更低，系统会隐式地授予你的应用程序这个权限。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，您需要添加权限

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

常量值:"android.permission.READ_PHONE_STATE"

Answer 2

将此权限添加到android manifest

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