# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName

When programming apps for Android, you usually want to test them on real Android devices.
This little gist describes how to do so using Ubuntu 14.

First, you need to download and install the Android development IDE (http://developer.android.com/sdk/index.html) and create an Android project which you want to debug.

Next, you need to setup the debugging mode on your Android device. Starting in Android 4.2 you need to enable the developer options first: 1) Go to settings 2) Go to About Phone 3) Tap the build number 10 times (or more, not sure ;)) and you will get the notification that you enabled it.

Then go to the developer settings and enable the debug mode for your phone. 

Now you think you can just plug it into your USB mode? - Nope.

Cache file name

• Just an md5 of the cache key
• Therefore not possible to identify key name from file name - md5 is one way

Cache directory name

• Level 1 - First 2 characters of filename
• Level 2 - Next 2 characters of filename

<?php

foreach (Cache::getMemory() as $cacheKey => $cacheValue)
{
    if (strpos($cacheKey, 'mypackage') !== false)
    {
        Cache::forget($cacheKey);
    }
