System application upgrade and system app versions?

 Hi,
I am having a scenario where I want to upgrade a preinstalled
application (let's say version 1.0). AFAIK, the new version (1.1) will
be installed on /data and will shadow the one in the system image.

However, if a new system image upgrade woudl contain a newer version
again (2.0), would Android run the 1.1 from /data or the 2.0 from the
new system image?

Another question - is there a <uses-sdk
android:maxSdkVersion="integer" /> tag that lets me specify that I do
not want to run on newer versions of the SDK, in case these wil
introduce unwanted behaviour and incompatible changes?

Cheers

1. Any sample code for using AccountManager to authenticate users?

I would like to use Google (or facebook) to authenticate my users. It
seems like I should be able to use the account manager to do this but
the documentation is a bit inadequate (the sample of writing your own
authenticator really isn't what I want). Is there any sample code out
there showing how to do this?

2. Android OS Problem: Left-to-right alphabets are rendered incorrectly

Hello,

Android's textView does not correctly input characters when left-to-
right Unicode characters, such as those of Hebrew or Arabic, are used.
For languages such as Arabic, morph transformation is also required
that is not done correctly either (or at all!).

This is also obvious when using Facebook App on Android to read posts
in LTR languages, which is completely messed up and totally illegible.

Can someone from Android OS address this?

I would like to extend our patented virtual keyboard (MessagEase) for
Entering Hebrew, Persian, and Arabic, among other languages, but
currently it's impossible to do so.
