  How to Integrate or Work with Open Street Map (OSM) in an Android App (Kotlin) What is OSM? OpenStreetMap is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace it from aerial imagery, and also from other freely licensed geodata sources. OpenStreetMap (OSM) is a collaborative mapping project that aims to create a free and editable map of the world. It is built by a community of contributors who collect, verify, and update geographic data using GPS devices, aerial imagery, and local knowledge. Here’s an explanation of how OpenStreetMap works, with an example: Data Collection : OpenStreetMap relies on volunteers to collect data. Contributors can use GPS devices to record tracks while walking, cycling, or driving, or they can trace features from satellite or aerial imagery.

Sort a HashMap in Kotlin in ascending order but the first element is not used in sorting

-
  In Kotlin, you can arrange a HashMap’s values in ascending order while preserving the first element’s original position. This can be achieved by utilizing the toList() function in conjunction with sortedBy and toMap. Let’s take a look at an example: fun main () { val originalMap = hashMapOf( "Key1" to 35 , "Key2" to 28 , "Key3" to 12 , "Key4" to 18 , // ... (add more key-value pairs as needed) ) // Sort the HashMap by values in ascending order, excluding the first element val sortedMap = originalMap.toList().drop( 1 ).sortedBy { it.second }.toMap() // Create the final sorted map with the first element val resultMap = linkedMapOf(originalMap.toList().first()) + sortedMap // Print the sorted map resultMap.forEach { (key, value) -> println( " $key : $value " ) } } Code Review originalMap.toList()  converts them  HashMap  to a list of pairs. .d...

  Read the Exif tag from the Image and also Read the location The ExifInterface class in Android development is widely utilized to store metadata, including camera settings, orientation, and even geographical coordinates, within image files using the Exchangeable image file format (Exif). If you require programmatic extraction of this information in your Android application, the ExifInterface class offers a convenient approach to accessing Exif metadata. Certainly! Here is an illustration showcasing the utilization of the metadata-extractor library in an Android application to extract metadata, including Exif data, from an image file. Step 1:  Dependency Inclusion In the build. gradle file of your app, you add the metadata-extractor library as a dependency. dependencies { // Other dependencies implementation ("com.drewnoakes:metadata-extractor: 2.18 . 0 ") } Step 2:  Permissions The AndroidManifest.xml file of the application contains the required permission to ac...
