android tips/notes

APK = Java (src,gen) + Resources (res)

R.java = glue between Java and Resources



make a project command-line compileable :
enter project workspace directory
> android update project --name --path .
> ant install ( will fail if no device to run on)
> ant debug (should succeed, as it only compiles a debug version)


info for android virtual machines located in ~/.android/avd/

adb (add sdk/platform-tools to PATH)

adb shell

adb devices, adb -s

To get nexus one working : edit /etc/udev/rules.d/51-android.rules and add
SUBSYSTEM=="usb", ATTR{idVendor}=="18D1", MODE="0666", GROUP="plugdev".

then unhook phone, and restart everything, then allow debugging on phone, and hook it in
and then start eclipse .... that seemed to do the trick

18D1 is the vendor code, i believe for google - don't use the htc one.                             


Services : code that runs in the background (no UI)
Content Providers : share content with applications across application boundaries, e.g. contacts


LOGCAT
from project folder :
> adb logcat StatusActivity:* *:s

apparently, android sdk 11 and higher doesn't allow potentially long-running things to happen in the foreground thread because it could lead to the dreaded "application not responding...or w/e" error.  From that I'll get a StrictMode exception - use a lower target version of android OR put the faulty code in an async task in the background.... reference : http://stackoverflow.com/questions/6976317/android-http-connection-exception
