If you are in the unfortunate situation where you think that your spouse is having an affair, an Android GPS app is a useful tool to finding out the truth. By using an Android tracking app, you can easily track the location of your spouse, and verify that they are where they said they are.
Gone are the days of expensive GPS tracking devices that you attach to your spouse's car, using an Android GPS app, you can easily track your spouse by installing the Android tracking app directly on their Android device versus having to install a piece of hardware somewhere on their car.
We all carry our phones wherever we go, so having a way to track your spouse's Android cell, is by far the best way (both in terms of cost and ease of use) to track a cheating spouse and gather the evidence you need to find out if they really are cheating. Whey spend hundreds of dollars on expensive GPS tracking hardware.
ANDROID GPS APP > How do they work?
The way an Android tracking app works is you install it directly on the Android device that you want to track. Once installed, the tracking app will transmit GPS coordinates to an online account that you set up at time of purchase. This enables you to log into your account and view both historical and real time GPS coordinates of your spouse.
To view where the GPS coordinates are on a map, you simply click on the GPS coordinates and you will be directed to Google Maps, where the coordinates will appear on the map giving you an exact location of where your spouse was at that point in time. Since the app uses Google Maps to show your spouses location, you can take advantage of all the features offered by Google Maps such as zooming in or out, changing the type of map shown to a street or terrain view, find out local landmarks & businesses, and even get driving directions to the location.
Android tracking software is a fantastic way to track any Android cell phone and find out where your spouse is going. You will not find an easier way to keep an eye on your spouse and track their location in real time.
ANDROID GPS APP > Where to buy?
There are a variety of apps that enable you to track an Android phone. In fact if you do a search on Google for 'Android tracking' or 'Android spy' you will see 20-30 of these kind of apps. The best advice I can give is to determine what your budget is, and what features you want in an Android tracking app, then tailor your purchase based on what your budget and needs are.
One thing to keep in mind is that you can go with a "visible" or "hidden" tracking app.  Make sure you know which one the Android app is that you purchase.
For example, you might want to be open with your spouse and let them know you are tracking them for "safety" reasons.  Others might want to secretly track an Android, and need software that is completely hidden, and therefore you definitely should go for Android spy software. (MobiStealth @ www.mobistealthSPY.com makes some of the best)
Regardless which type of Android GPS app you purchase, just make sure you know exactly what features you want prior to making your decision. This will prevent you from having to go back and spend more money on more software. It's better to do the research right the first time, and get an Android tracking app that matches your budget and needs.

As with many new HTC units, an integrated 5 mega pixel digital camera is provided as standard, which operates at a pixel resolution of 2592x 1944 pixels.  This results in high quality and clarity of the still images.  A number of image enhancing features are provided as standard such as Autofocus, smile detection and an LED flash.  Therefore, even low lighting conditions are not an issue of the camera and great quality still images can still be taken.  Geo-tagging is also included which operates thanks to GPS and automatically records the location at which a photo was taken.  As an alternative method of image capture, the camera can also shoot video footage.
The Wildfire is relatively compact for an HTC handset.  It measures 106.8x 60.4x 12 mm and weighs in at an impressively light weight 118 g.  Its compact dimensions and light weight make it a pocket friendly handset which is a pleasure to use with one hand.  In comparison to other phones from the manufacturer, the appearance of the Wildfire could be described as chunky, with aesthetic appeal coming from its simple lines and the availability of a number of colour variants including black, brown, white and red.  Therefore it offers aesthetic appeal to style conscious users who also view their phone as a fashion statement.

Thanks to a long list of applications and features, the HTC Wildfire boasts a high level of everyday versatility.  Entertainment features include a versatile internal media player as well as a number of pre-installed games and a stereo FM radio player with RDS.  Social networkers are catered for with Facebook, twitter and Flickr integration which allows them to communicate with friends and family and share their thoughts in a matter of seconds.  GPS with A-GPS support is provided which allows features such as the aforementioned geo-tagging and a digital compass to function, as well as Google maps.  YouTube, Google talk and Picasa all boast dedicated applications within the HTC Wildfire.
Connection to cellular networks is provided courtesy of class 10 versions of both EDGE and GPRS.  This provides it with connections in all but the most isolated of locations.  In order to access the Internet, the handset initially relies on 3G coverage, whereby an HSDPA connection provides access to the Internet at speeds of up to 7.2 mega bytes per second.  A faster Internet connection can be attained however thanks to integrated Wi-Fi Technology which senses the signals provided by wireless Internet routers where available, and utilises these to provide an enhanced browsing experience.  Both Bluetooth and micro USB connections allow users to carry out a number of tasks by connecting the handset both wirelessly and directly to other compatible hardware devices such as other mobile phones and computers.
HTC could be described as something of a veteran and it comes to the manufacture and design of Smartphones.  With handsets like the Wildfire, it is easy to see the level of expertise.

A Guide To Installing APK Apps On Your Google Android Phone
Because the Android operating system is a relative newcomer to the mobile phone market, a strong and cohesive Android Internet support community appears to be lacking. Without an adequate Android support system in place, many Android users are left in the dark when it comes to many tricky tasks, like installing third party applications to their Android mobile phones. In order to install third party applications to your Android phone, you need to install APK, or Android Package, files. In this article, we will cover the two ways you can install APK files to your Android phone and show you how to take advantage of the wide variety of third party Android applications currently available.

Installing Applications Through the Android Market

The Android Market is essentially Android's answer to Apple's iPhone App Store. As of September 2009, the Android Market already offered well over 10,000 applications, and this number has only continued to grow. In addition to the applications the Android Market offers, you can also use it to install other downloaded third party applications.

1. Copy the APK file to your Android's memory card and insert the card into your phone.
2. Download and install the Apps Installer application from the Android Market
3. Once installed, the Apps Installer will display the APK files on the memory card.
4. Click and install your APK files.

Installing Applications With Android SDK

It is possible to install APK files without utilizing the Android Market, although the process is more difficult and complex. To avoid the Android Market, you need to use Android SDK.

1. Download and install the Google Android SDK program and the Android USB drivers. The download links are as follows:http://code.google.com/android/intro/installing.html
2. http://dl.google.com/android/android_usb_windows.zip
3. You need to modify your Android's settings to allow the installation of applications from other sources. Under "Settings," select "Application Settings" and then enable "Unknown Sources." Also under "Settings," select "SD Card" and "Phone Storage," and finally enable "Disable Use for USB Storage"
4. This last step is easy. Open Command Prompt and type the following: adb install <1>/<2>.apk
5. However, when you type the command, replace <1> with the path to your APK file and replace <2> with the name of the APK file.
6. You're done! Your application is now ready for your use and enjoyment.

Android spy app is a mobile monitoring, tracking, and spying software application which is utilized to spy on Android cell phones using the Android OS, such as the Motrola Droid, Nexus One phones.

The way Android spy apps work, is that a individual should download the Android spy app directly into the Android device. This can be accomplished via the cell phone's internet browser.

Immediately after the Android spy app is downloaded and set up, the Android app becomes undetectable and straight away starts to secretly records a range of information (call logs, SMS messages, GPS locations), and then anonymously uploads all the info to an world-wide-web account. All of this happens in the background, while the person is using their phone.

The individual that installed the software, can now log into their account, and view all the activity recorded on the Android cell phonephone.

The following is a list of the most typical capabilities found on Android spy apps

• Listen To Calls - Using an Android spy app, you can secretly listen to calls made from the Android phone you are monitoring.

• Remote Monitoring - Some Android spy apps also enable you to secretly listen in on the surroundings of the Android phone.

• Stealth GPS Tracking - With Stealth GPS tracking, it is possible to secretly monitor the GPS coordinates of the person you are spying on. Areas are captured and uploaded in fifteen minute intervals, giving you a obvious image exactly where the Android user is. Locations are then shown using Google Maps.

• View Photos - This Android spy app feature enables you to secretly view photos stored on the Android device.

• Secretly Read Text Messages - All SMS messages which are received or sent from the Android cell are secretly recorded. Full contents of each message are recorded along with the time and date sent.

• View Call History Logs - This Android spy app feature will enable you to secretly read all incoming/outgoing call details of the cellular cellphone. In addition to the call information, the name stored in the phone's contact list / address book that is assocated to the number in the call logs will be shown. This will give you some insight into the name they are assigning that number.

What are the reasons why someone would want to use Android spy phone apps? Here are a some of the most well known reasons.

* Catch A Suspected Cheating Spouse: The most common reason why somebody purchases Android spy apps, is to spy on their spouse or partner. With Android Spy phone software, a concerned spouse can easily find out the truth and determine if their partner is indeed being faithful. The great thing about Android spy apps is it enables a suspicious spouse to not only track their cheating spouse, but also listen to their calls, surroundings, and read their text messages.  If their spouse is indeed having an affair, an Android spy app will uncover the truth.  It's not "if" they will get caught, it's "when" it will happen.  There is no way a cheating spouse can escape the powerful spy features found on an Android spy app.
Other features include....

* Monitor Children Cell Use: For parents who are concerned about their teen's cellular use, or need a way to monitor their children, an Android spy app is a perfect choice. Maybe they are worried their teen is involved in a prohibited activity or they want to make sure that their teen is where they are supposed to be, with Android spy phone software, all of this is possible.

* Worker Monitoring: Android spy apps could also be used to watch cell use on company provided telephones. In certain industries, more buyer communiction is occuring on cell telephones through texts. Without knowing what is being said and / or not being able to have a record of the communication might be in violation of compliance rules and  laws. Also, in the event of a potential suit, not having records of particular customer communication may put the company in peril. With this type of software installed on company provided cell phones, bosses can keep records of such activity.

Final Thoughts

In summary, Android spy phone software is really a cell phone monitoring & tracking application that's used for a range of reasons to observe a person using an Android cellphone. Even though not everyone will agree with some of the reasons for wanting to spy on an Android cell phone, it's up to the individual who purchases the software program to choose the best use.

 A unique application, Ghost radar to detect the existence of ghosts.

From the http://spudpickles.com/node/34

Ghost Radar is a portable application designed to detect paranormal activity. Currently supported portable devices include the iPhone, iPod touch, iPad, BlackBerry and Android devices. Ghost Radar attempts to detect paranormal activity by using various sensors on the device on which it is running. Like traditional paranormal detecting equipment Ghost Radar employs sensors that measure electromagnetic fields, vibrations, and sounds. However, traditional paranormal equipment can be easily fooled when simple mundane bursts of normal electromagnetic fields, vibrations and sounds occur. Ghost Radar sets itself apart by analyzing the readings from sensors giving indications only when interesting patterns in the readings have been made.

Ghost Radar employs a proprietary algorithm to analyze the quantum flux. This application does NOT detect EMF nor gravity. Readings for various sensors are analyzed to detect QUANTUM Fluctuations. Interpretations of the sensor readings are displayed graphically as blips on the radar along with numeric and textual readouts on the VOX. Use your Ghost Radar to hunt for odd changes in the flux. Hunters of all types may find anomalous areas of their environment where readings simply can't be explained. You be the judge. Are the results of your hunting evidence of paranormal activity?
