Efter en “hej-verden” sag i emulatoren, er næste logiske skridt at overføre programmet til mobilen. Eclipse kompilerer automatisk til debug mode. Teoretisk set burde man kunne overføre .apk-filen via USB.

.apk-filen kan overføres til skrivebordet – eller hvor man nu vil have den via drag’n-drop.

Via USB til hardware

Herefter var det kun et spørgsmål om at overføre filen til mobilen via USB. Jeg lagde den i mappen Download. Telefonen fandt .apk filen, og spurgte om programmet skulle installeres. Og det skulle det jo.

Efter nogle sekunders installation kørte programmet (der ikke kan noget endnu…) på mobilen.

Eclipse Users

If you are developing in Eclipse/ADT (and have set up Keytool and Jarsigner as described above in Basic Setup for Signing), signing in debug mode is enabled by default. When you run or debug your application, ADT signs the .apk with the debug certificate, runs zipalign on the package, then installs it on the selected emulator or connected device. No specific action on your part is needed, provided ADT has access to Keytool.

via Signing Your Applications | Android Developers.

Once the .apk is built, it must be signed with either a debug or release key before it can be installed to a device.

Eclipse outputs an .apk file automatically to the bin folder of the project, so you do not have to do anything extra to generate the .apk.
