Cannot install .apk on phone

Question

I've just knocked together my first app, have released and signed it and transferred to my phone, but cannot get it to install on my phone - after going through the screen saying 'Do you want to install this application' and clicking install, I just get a message saying 'Application not installed' with no further explanation. I had checked the signing using jarsigner -verify.

I have uploaded the .apk to http://ubuntuone.com/p/ESB/ and obtained the log using the LogCollector app on my phone. The relevant extract is reproduced below.

Log Collector version: 1.1.0
Device model: HTC Desire
Firmware version: 2.2

Many thanks for your help.

Edit 02/09/2010 I have modified the main.xml file again by removing pretty much all the whitespace. It still does not install but is not quite the same error: it's claiming there is a zip file error although I notice that certificates do appear further down the list. If this is not something I'm obviously doing wrong, would it be better if I raised on android developers mailing list?

Answer 1

I've seen corrupted .apks that won't load on a device, with weird IOExceptions. Following these steps in Eclipse seems to prevent the problems I've seen:

1. Make sure that Project -> Build Automatically is turned off (that is, unchecked)
2. Project -> Clean..., select "Clean All Projects", make sure the "Start a Build Automatically" checkbox is unchecked, and click OK.
3. Use File -> Export -> Android -> Export Android Application to create the APK
