Android: Using Google maps app to show places in your application

By -
When we are developing android application with maps functionality normally developers tries to use Google maps API for this. But if your requirement is simple it may be more easy and effective to use existing maps application by a intent. In this application I'm going to show how to show the nearest hospital in your application.

Note- To make this work your app and emulator must be created using Google APIs not android APIs. (Both are the same but if you are not using Google maps API map application functionality is not available to you).

Here is the code,

LocationManager  locMgr  = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Location recentLoc = locMgr.getLastKnownLocation(LocationManager.GPS_PROVIDER);
double lat = recentLoc.getLatitude();
double lon = recentLoc.getLongitude();
String geoURI = String.format("geo:%f,%f?q=hospital", lat, lon);
Uri geo = Uri.parse(geoURI);
Intent geoMap = new Intent(Intent.ACTION_VIEW, geo);
startActivity(geoMap);


In the geoURI string you can change the hospital in to any other place. If you just wan't to center the map to your location do not include the question mark and latter part in geoURI .

This is how my application shows the nearest hospital to my location.

If you test this in Android emulator you have to send your location to the emulator using DDMS in eclipse because. Otherwise it will throw a null pointer exception. You can find articles on how to do this in internet.

    A good detox shampoo removes all dirt, drug metabolites, and toxins from your hair and scalp without harming your hair or scalp's health. Here are some additional general guidelines for selecting the best drug detox for you: Natural ingredients that are gentle on your scalp and hair, such as green tea extract and apple cider vinegar, should be included in the product. Look for botanical extracts like lemon, mint, and sage in the product. These items keep your hair and scalp healthy while also ensuring that it smells good. Some detox shampoos are harsh on your hair, making it look and feel even worse. If your hair is already in bad shape, a complex shampoo could exacerbate the problem.

Create new Java Class files at runtime

By -
When we write programs usual method is to write all the code compile it and run. But when we try to complex things some times we may want to generate a new class and use it at runtime. As an example I wanted to create a class which parse a xml message and create a new Java object from that data. This is used in web server. So that result object varies according to the web service which is deployed. The solution was to inspect the service at deployment time and create a new parser class according to that in the service deployment time. It has to be noted that this parser had to be generated as a .class file and dynamically added to the classpath. So the result was to use a bytecode manupulation library. There are few bytecode manuplulation libraries available as ASM and JavaAssist . I used JavaAssist for this. The reason for using JavaAssist is it is simple to create a new class from the scratch using JavaAssit. When we create new class files using JavaAssit we have to create all t

Using iReport plugin for Jasper Reports in Netbeans

Jasper reports is a very useful frame work for genarating reports, saving them as PDF,etc. iReport make it more easy because we can design reports using graphical methods from it. Also it is available as a plugin for NetBeans. You can download iReport Netbeans plugin from here . there are for files in the Zip folder. You can install them by at one by selecting all of them when you select the plugin to install from Netbeans (If you don't know how to install a plugin for Netbeans search for a tutorial). To use Jasper Reports in your application you have to add some libraries. But the problem is these libraries are heavily coupled with each other. So downloading each one is a very difficult task because there are problems like versions don't match, some libraries are outdated, etc.etc. There is a easy method. After installing the plugin Netbeans will automatically add the Jasper Reports library to its library collection. But it is missing one important library. So you have t
