Android app kod
Senaste videon, EM-kval i bakgrunden så man var lite ofokuserad.

Ni behöver SendToPhp.java, STRINGS.XML och MAIN.XML i erat projekt.
Zippade hela min projektmapp, hoppas det funkar, APK filen är den färdiga filen redo att installeras på Androidluren.
För att appen vill använda Internet så måste ni lägga till:
Kod: Markera allt
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
I eran AndroidManifest.xml fil.
Snippen ska ligga
ovanför <uses-sdk>
SendToPhp.java
Ganska mycket kod, men det är många funktioner oxå
Den börjar med att importera allt nödvändigt.
Kom ihåg att den första raden package send.toPHP är ditt projekt namn i Eclipse.
Nu använder jag mig inte av PHP längre men skitsamma.
