How to create google map with drag marker to get user location with auto correct location edit text ...


For drag and drop with user location You have to create a google map fragment activity

below are the xml code of google map xml

<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".GetUserLocationActivity">

                fullAdress.setText("...");
            }
        }
    }
}




for this you need following depandancy 




below are the depandancy :




implementation 'com.google.code.gson:gson:2.3.1'


implementation 'com.google.android.gms:play-services-maps:17.0.0'


implementation 'com.github.delight-im:Android-SimpleLocation:v1.0.1'


implementation 'com.google.android.gms:play-services-places:17.0.0'implementation 'com.google.android.libraries.places:places:2.0.0'

how to create chat gpt app in android with java code




























  I'd be happy to provide you with some sample Java code for a chat GPT app in Android, however it is important to note that creating a complete and functional app requires a solid understanding of Android development, Java and OpenAI API, and also the code I provide here is just a skeleton or a sample of what it would look like in practice. You would need to import the OpenAI API library and configure it with your API key. Here is an example of how you might use the OpenAI Java client library to send user input to the GPT-3 model and receive the generated response: import openai.OpenAI;  public class ChatGPT {     private OpenAI openai;     private String apiKey = "YOUR_API_KEY";          public ChatGPT() {         openai = new OpenAI(apiKey);     }          public String generateResponse(String input) {         String response = "";         try {             response = openai.completions().create()                     .engine("text-davinci-002")     ...
