API missing from PackageManager
<p>It's weird I found PackageManager has public APIs like installPackage(...)/deletePackage(...) although in the comment it's marked as <strong>Hide</strong>, here <a href="http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.2_r1.1/android/content/pm/PackageManager.java#PackageManager.deletePackage%28java.lang.String%2Candroid.content.pm.IPackageDeleteObserver%2Cint%29" rel="nofollow">http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.2_r1.1/android/content/pm/PackageManager.java#PackageManager.deletePackage%28java.lang.String%2Candroid.content.pm.IPackageDeleteObserver%2Cint%29</a>, but the reference page google provides hide this API.</p>

<p>So my question is how can I access such APIs?</p>

<p>Thank you all very much for help.</p>

<p>Kindest regards,
Nessus.</p>
