Please Help me how can i upload image from Android Application to Mysql database...

Answer 1

You can upload pic using Gotev Upload Service

In gradle dependencies

dependencies {  
   implementation "net.gotev:uploadservice:3.4.2"
}

Then in Activity

public void uploadMultipart(final Context context) {    
    try {  
        String uploadId =  
                new MultipartUploadRequest(context, "your URL here")  
                        .addFileToUpload("data.getData() here", "user_pic")                           
                        .addParameter("user_name", "param value") 
                        .addParameter("user_email", "param value") 
                        .addParameter("user_city", "param value") 
                        .addParameter("user_area", "param value") 
                        .addParameter("username", "param value")  
                        .addParameter("password", "param value")        
                        .setNotificationConfig(new UploadNotificationConfig())  
                            .setMaxRetries(2)  
                            .startUpload();  

        } catch (Exception exc) {  
            Toast.makeText(context, "Exception: "+exc.getMessage(), Toast.LENGTH_SHORT).show();  
        }  
    }
