Question

I’m just having a new problem. All my Android applications, which are perfectly functional in the emulator, alsofail to install on my phone.

A few weeks ago, I had no problem deploying these applications. The only thing changed in the meantime is the Java version (I have updated to 1.7).

I have tried to :
– re-create my keystore,
– uninstall the previous version from the phone before trying to install the new one

but the problem still remains…

Any idea?

Thanks in advance for the time you will spend trying to help me.

Answer 1

I think that Android SDK still does not support java 7. Try to change project properties so it compiles against java JDK 5 or 6.

1. Right click on your project and select “Propertie”,
2. Then select “Java Compiler”
3. Check “Enable project specific settings”
4. Select 1.5 or 1.6 from “Compiler compliance settings”.

Hope that this helps.
