某些Samsung APK文件无法安装，因为它们被AASAParser阻止。
例如：
07-19 11:03:38.631 1468 1720 I AASAASKS: list is removed : com.sec.android.app.sbrowser

我在APK文件中找到了这些属性。
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<TOKEN>
<MODE TYPE="0"/>
<PACKAGE name="com.samsung.android.app.notes"/>
<DIGEST value="040f3e0051c717b9da7a0666850fc9d3150d998a9e4e6f1f38edc0d7b0689354"/>
<CREATE date="20180607"/>
<VERSION value="18448835"/>
<INDEX value="1.1"/>
</TOKEN>
将它们与未被阻止的APK文件进行比较后，我观察到以下内容：
if MOD TYPE = 0, then PackageManager blocks the apk.
if MOD TYPE = 1, then PackageManager does not block it.
三星为什么要这样做？
谢谢。
