“找不到MyFirstApp.apk！”错误

Question

I don't understand really what's going on. I followed the basic android "Hello World" program tutorial on Google's website. I made basically no alteration to any code... I just ran it... and it's not running. The following occurs in the console each time I run the program:

[2013-05-27 11:44:46 - MyFirstApp] ------------------------------
[2013-05-27 11:44:46 - MyFirstApp] Android Launch!
[2013-05-27 11:44:46 - MyFirstApp] adb is running normally.
[2013-05-27 11:44:46 - MyFirstApp] Could not find MyFirstApp.apk!

So, what am I supposed to do? Did I not install something correctly? I thought I did, but it's a complicated installation so I'm not certain how to go about this.

If someone could just explain what the error message means... that could help a ton.

Answer 1

Your project is probably the library project.

Unselect "Is Library" in project's properties Android section.

Answer 2

It is because there is no MyFirstApp.apk that the adb can upload in the simulator or device. Just clean the application and build it again from Project>Clean and then Project>Build All . The MyFirstApp.apk will be created.

And then try to run your application.
