HB Blog 23: Step By Step Guide How To Root Mobile Device.

What is Rooting Android Devices? Heard as, "device should be rooted". 

Rooting is a process that allows you to attain root access to the Android operating system code (the equivalent term for Apple devices id jail breaking). It gives you privileges to modify the software code on the device or install other software that the manufacturer wouldn’t normally allow you to.

I will show a very basic tutorial for rooting the android mobile device. But, before that I prefer to clear out the advantages as well as disadvantages for rooting the device.

Advantages:-

1. Install Custom ROM on your device to add themes and change look and feel.
2. Backing up device data using Apps such as Titanium backup, Astro, etc.
3. Access Apps and Games that requires root support.
4. Removing unwanted Apps and Games.
5. Install Applications on SD Card.

Disadvantages:-

1. It may result into bricking(damaging/corrupting) the software of the device. Solution - Sp tools is a tool with which you can flash new firmwares or recoveries. Or fix your Phone if it is soft bricked. 
2. It will void your warranty. Solution - You can always get your warranty back by unrooting your device.
3. Malware can easily breach your mobile security.
   Solution -  Have a good paid anti-virus. Thats all, I can say on this.

Step By Step Guide How To Root Mobile Device:-

Step 1 : Plug in and connect your android device to your computer via USB and it will initiate driver installation for the device. Install them. Skip this if you have done this already before.

Step 2 : Unplug and re-connect, but this time select "Charge only" to sure that your phone’s SD Card in not mounted to your PC during the rooting process.

Step 3 : Put your android into USB Debugging mode. Go to Settings > Applications > Development and enable USB Debugging. This will enable SuperOneClick to root your android device by running the exploit from your PC while connected via USB.
Check all the steps. All drivers should be installed. You SD card must be un-mounted and USB Debugging must be enabled 
Step 4 : Download superoneclick software from below link,
Download SuperOneClick
Step 5 : Open the superoneclick folder you’ve downloaded and run SuperOneClick.exe file. You will see the window (below). Click on the "Root" button. And if everything goes well you will get OK messages a lot.

 Step 6 : It takes just a minute. And after its done you will see a "Running a Su test Success!" which means the rooting process is completed. Go to your phone app drawer and you will see Superuser icon which means you now have root access. (reboot the phone if you don’t see it).

Superuser is a small utility that manges access to the root permissions, kind of like a gate keeper. It makes sure that applications can’t make changes to your device without asking you first.

Its done, enjoy the hack. :)

HB Blog 21: Google Map Geo-Fencing Android [Tutorial].

    There are many places on Internet where you can find how to integrate Google Map using Android Api. You can try out few below links that can guide you to start it.

http://developer.android.com/google/play-services/maps.html
http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/
http://www.tutorialspoint.com/android/android_google_maps.htm
http://www.vogella.com/tutorials/AndroidGoogleMaps/article.html

But,in this tutorial I would like to move on with it. This tutorial will explain how to integrate geo-fencing in Google map.

Firstly, Integrate Google map - that you can using above few links.
In short, you need

Google Map - Activity file to create an object of GoogleMap and get the reference of map from the xml layout file.

Google Map - Layout file to add the map fragment.

Google Map - AndroidManifest file to add some permissions along with the Google Map API key.

Secondly, add marker and addCircle as below code snippets,

1 2 3 4 5 6 7 8 9 10

Marker stopMarker = googleMap.addMarker(new MarkerOptions() .draggable(true) .position(new LatLng(latitude, longitude)) .title(title) .icon(BitmapDescriptorFactory .fromResource(R.drawable.ic_launcher))); googleMap.addCircle(new CircleOptions() .center(new LatLng(latitude, longitude)).radius(radius) .fillColor(Color.parseColor("#B2A9F6")));

Finally, add your api key in android manifest.I hope you added during map integration. Now, you can run your app and hope you try out other google map attributes as well.
