[SOLVED] Android: Handling gzipped content while downloading

On file download you can check the content type and if its gzipped - unzip it on the fly:

URLConnection connection = url.openConnection();
InputStream stream = connection.getInputStream();
if ("gzip".equals(connection.getContentEncoding())) {
stream = new GZIPInputStream(stream));
}

[SOLVED] Android: Get an string array from an array.xml resource

Here you can see how to retrieve values from array.xml

Log.i("test",getImageQualityAsString(1));

array.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="image_export_list_preference">
        <item>480x320</item>
        <item>800x480</item>
        <item>1024x768</item>
    </string-array>
    <string-array name="entryvalues_image_export_list_preference">
        <item>0</item>
        <item>1</item>
        <item>2</item>
    </string-array>
</resources>

Function:

private String getImageQualityAsString(int sizeItem){

        try {
            String[] bases = getResources().getStringArray(R.array.image_export_list_preference);

            return bases[sizeItem];

        } catch (Exception e) {
            return "";
        }

[SOLVED] Share log via Browser

This guide assumes you have a remote server, called loghost.example.org that you are going to use to avoid any firewall issues.

First make sure you have netcat-openbsd and NOT netcat traditional installed.

sudo apt-get install netcat-openbsd

Then to ensure your system is working try the following basic netcat tip.

Now to share my logging output I run on my laptop:

tail -f /var/log/syslog | ssh loghost "nc -v -l 8000"

Now to share my log with a remote collegue, he simply runs:

curl http://loghost.example.org.org:8000

or http://loghost.example.org:8000 in a browser

[SOLVED]Building CSS sprites with Bash & Imagemagick

If you want to automatically generate image sprites - css file just use this script

$ spriteit.sh button button '*.png'

Output:

Generating sprite file...
executing: convert button_disabled.png button_hover.png button.png button_selected.png -append button/button-sprite.png
Sprite complete! - Creating css & test output...
        #1 done
        #2 done
        #3 done
        #4 done

Complete! - 4 sprites created, css written & test page output.

Script source:

#!/bin/bash

# uses imagemagick to stich together all images in a folder and
# then writes a css file with the correct offsets along with a
# test html page for verification that its all good

if [ $# -gt 0 ]
then

    if [ 'x' != 'x'$4 ]
    then
        ext2=.$4; # the extension to iterate over for input files
    else
        ext2=".png"; # the extension to iterate over for input files
    fi

    if [ 'x' != 'x'$3 ]
    then
        #ext="."$3; # the extension to iterate over for input files
        ext=$3; # the extension to iterate over for input files
    else
        ext=".gif"; # the extension to iterate over for input files
    fi

    name=$1; # output will be placed in a folder named this

    if [ $2 ]
    then
