I would be really grateful for some urgent advice:- I was merrily building my apps (using eclipse) for Android platform 2.2. Everything all working lovely and ready to upload to the marketplace. I thought I would try to install Google Play Licensing and in the process, I was told to download the LVL but that was not available in my SDK download list - and I read I had to updrage my SDK and ADT to the latest. So I did, I now have: ADT 17.0.0 along with ANDROID DDMS, hierarchy viewer and Traceview at 17.0.0 with Eclipse IDE 1.4.2 And I also upgraded my SDK Android 2.2 stuff to the latest. Now:- I have no errors in my app workplaces on Eclipse. But now when I run the apps, they build but force close straight away upon loading. This includes the app I was working on (and working perfectly before) and all the other apps I have ever made. Every app now force closes and I dont know what to do. Been up all night and was ready to upload them to the market place... :( Any help!? Thanks! Please!
