Issue while publishing Android app: "This application is available to over 0 devices" <p>Hello: I note this question has been answered at <a href="http://stackoverflow.com/q/8212956/936042">http://stackoverflow.com/q/8212956/936042</a> but I hope y'all will entertain my question since I am not able to reproduce the solution.</p> <p>When I upload my APK to the Android market, the message says "available to over 578 devices" (this is before activation). As soon as I begin to make other changes (such as changing the contact email address) the message changes to "This application is available to over 0 devices". I use Eclipse's Export option to created the final, signed APK.</p> <p>My Android app uses 3 external JARs (http://code.google.com/p/javamail-android/downloads/list). I add them to the project using Project/Properties/Java Build Path/Libraries/Add External JARs.</p> <p>The solution posted at the link above implicates the use of external JARS, and their being embedded into the APK in some inappropriate manner, as the cause for this issue:</p> <blockquote> <p>my mistake was that I included .jar files in order to add some external libraries and not the respective external class folders. When I removed the .jar files and I just added the class folder then devices became over 700 again.</p> </blockquote> <p>I don't quite follow the above explanation. If someone (especially the original author) could lay it out in greater detail, I'll be very obliged.</p> <p>Thanks!</p> <p>PVS</p>
