Can I upgrade an untrusted app from Android Market?
<p>I have a version 1.0 App installed using "adb install". I have the same App with version 2.0 in the market. Can we upgrade the application automatically?</p>

<p>My test results are:</p>

<p>if an App is installed by "adb install" or untrusted source, we cannot see it from "My App" menu item in Market App. Now I have the same App with version 2.0 in the market, I can use Market App search feature to find the app in the Market. But is shows open button not upgrade button as I expected. Based on my test results, it seems we cannot upgrade the application automatically in our case. Even I tried manually to upgrade the App, I have to remove the app installed by adb install or untrusted source first, then install new version from the market. </p>

<p>My question is do we have a way to upgrade the app automatically if the app to be upgraded is from untrusted source and new version App is in Android Market? or at least, the Market app UI should display upgrade button not open button.</p>
