On some Android 2.3.X phones(e.g. my Acer Liquid Metal S120, WIFI proxy settings are missed in WIFI settings. The work around are below:

Option1: Use Opera Browser

Open the Opera browser app, in the URL field, type opera:config, at this time the Preferences Editor should have opened in your screen.
Scroll down to proxy menu, in the HTTP Server and HTTPS Server, enter your proxy setting with the following format <Proxy IP>:<Port>. E.g. 192.168.1.1:3128

Options 2: Install "HTTP proxy settings" app in Google play. (It may not work on some phones.)

To fix it, turn off the phone and then press and hold the Power + Volume Down + Home buttons. Wait till you see the droid with the progress bar under it then release the buttons.

在分配能力的时候，不要将点数分配到陆指此能力，然後再询问确定时连按两次“否”，这时游标会停留在陆指的地方，然後按方向键的←，如果画面上出现数字的话，就按方向键的↑两次、L，然後剩馀的点数就会增加，然後我们就可以创造一个全能力满点的新君主了。但是要注意，点数刚好就可以，不要按过头了，要不然会无法结束分配能力的画面。

2011-12-03T19:25:00.001-08:00

Droidhen Defender is an free Android game.

Prerequisites:

Root your device. Do not how to root your device? google + root
Install a root file manager app: super manager (free) or root explorer (non-free)

The game saves files at /data/data/com.droidhen.defender/shared_prefs, named: save0.xml save1.xml save2.xml

The save file is in the following format:

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<int name="magicStone" value="6" />
<string name="magicStonecheckValue">1e0e72ebd00ab9e2535db46431d29e93</string>
<int name="singleRetry" value="0" />
<int name="stage" value="2" />

<string name="goldcheckValue">a1a566f1d427b549f7b7c8dac5f0cb36</string>
<int name="hardMode" value="0" />
</map>

To change the values of gold and magic stone, we need to not only change the value of gold and magicStone, but also goldcheckValue and magicStonecheckValue. How to calculate the checkValue? Use the following fomula:

checkValue = md5(value+"checkChar")

To calculate the checkValue for value 100000000:

If you are using Mac, run
```
md5 -s 100000000checkChar
```
in the Terminal window.
If you are using Linux run
```
echo -n 100000000checkChar | md5sum
```
in the terminal window
Or you can open this web page and type 100000000checkChar and click Calculate MD5 button

You should get the checkValue for 100000000,

4293191e6b63499927db54f204f7eb30

You can copy the file, e.g. save0.xml, to /mnt/sdcard/ using your root file manager: super manager.
Edit it with text editor
- Modify the gold and magicStone to 100000000
- Modify the goldcheckValue and magicStonecheckValue to 4293191e6b63499927db54f204f7eb30

You modified save0.xml looks like below:

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<int name="magicStone" value="100000000" />
<string name="magicStonecheckValue">4293191e6b63499927db54f204f7eb30</string>
<int name="singleRetry" value="0" />
<int name="stage" value="2" />
<int name="gold" value="100000000" />
<string name="goldcheckValue">4293191e6b63499927db54f204f7eb30</string>
<int name="hardMode" value="0" />
</map>

Copy the modified save0.xml file back to /data/data/com.droidhen.defender/shared_prefs
Start the game and load the saved file, you can now use the gold and magic stone to buy and upgrade anything.
