You must be more clear.
When you compile, with the device connected, the apk file is automaticaly transfered to the device.
If you are using the Emulator, the apk file will be transfered to the Emulator.
Study up on your French and read the post above yours.
The generated APK gets put into the "Objects" subfolder of your project's folder.
If you want to build an APK and for some reason do not want to have it automatically transfer to your device, just build it without a device connected (wired or wirelessly).
