如何在自助服务终端模式/锁定任务模式下将安装程序包列入白名单？

Question

I have created an kiosk application it has update functionality for other application within the device but the installer package is blocked. How to whitelist installer package?

I have tried whitelisting this installer package but it is not working. Maybe I'm missing an additional application to whitelist.

...//My other whitelisted apps
private static String INSTALLER_PACKAGE = "com.google.android.packageInstaller";
private static String[] APP_PACKAGES = { ..., INSTALLER_PACKAGE};
...
dpm.setLockTaskPackages(cn, active ? APP_PACKAGES : new String[]{});

If you are setting FLAG_ACTIVITY_NEW_TASK flag on the ACTION_INSTALL_PACKAGE intent it will generally tell you "Unpinning is not allowed" when trying to invoke the PackageInstaller to update.

For instance, in this example (AppCenter)

Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
intent.setData(fileUri);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // <-- giving me grief
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

I have found through my investigations that HockeyApp, Microsoft AppCenter and TestFairy is setting this flag, so I was unable to use their out-of-the-box in-app update solution when pinned (task locked). I'm also running android:launchMode="singleTask" for what it's worth.

I was however able to change HockeyApp's library to my liking. This was my initial inquiry https://github.com/bitstadium/HockeySDK-Android/issues/368
