My original Android<\/strong> version of TXT-2-PARK has been in the Google Play Store<\/a> for a little over a week now. But it was only on Saturday that I decided to install the release version onto my phone from the store itself, and found a problem.<\/p>\n

<\/p>\n

The application would download just fine, but at the point at which it started installing the Play Store<\/strong> app would complain, reporting that the “Package is not signed correctly<\/em>“, or words to that effect, and refuse to install the app.<\/p>\n

This was puzzling since I had had no such problem with my previous published app (the Simple Battery Widget<\/a>). Not to mention that any issue with the signing of the app would surely have been identified when I uploaded the APK ?<\/p>\n

After a bit of digging I found a number of people had had similar issues.<\/p>\n

In some cases, where a dev\/debug build had previously been installed on a device (as in my case), the problem was resolved by clearing the Play Store<\/strong> app cache, in others it required clearing ALL<\/em><\/strong> the Play Store<\/strong> app data.<\/p>\n

Unfortunately this didn’t fix the problem for me.<\/p>\n

A little more digging threw up the fact that for some reason some devices – but not all – seem to have trouble validating app signatures if they have been signed with the Java 7<\/strong> or 8<\/strong> SDK’s. The suggested solution in that case is to revert to the Java 6 SDK<\/strong>.<\/p>\n

In my current Windows 8.1 VM<\/strong> where I do my RO Elements<\/strong> work, I had indeed replaced my previous Java 6 SDK<\/strong> with Java 7<\/strong>.<\/p>\n

So I installed the Java 6 SDK<\/strong>, updated the necessary references in the PATH<\/strong> and Visual Studio<\/strong> (Oxygene<\/strong>) settings, rebuilt my Android<\/strong> solution, re-submitted to the Play Store<\/strong> and… problem solved. \ud83d\ude42<\/p>\n

Which just leaves the question of why the Play Store<\/strong> validation process accepts the signature on an app which the Play Store<\/strong> app<\/em> then rejects.<\/p>\n

But whatever the reason, it seems that signing apps with jarsigner<\/strong> from the Java 6 SDK<\/strong> is the way to avoid this particular problem.<\/p>\n

NOTE:<\/strong> This is not an Oxygene<\/strong> issue but one that could affect the signing of any Android<\/strong> app using the Java SDK tools.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
