In this Library, user can pick image from gallery and click image from camera

-set image into imageview

-get file to upload to server

To get a Git project into your build: Add it in your root build.gradle at the end of repositories:

	allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}

Add the dependency

    dependencies {
    	        implementation 'com.github.777665Abhi:ImageHandler:Tag'
    	}

Usage

To show image popup and select from either camera or gallery

ImageHandler(this).showImagePickerDialog()

To set image from camera

 ImageHandler(this).setImageByCamera()

To set image from gallery

   ImageHandler(this).setImageByGallery()

To set Image selected into imageview in onActivityResult method

      override fun onActivityResult(requestCode: Int, resultCode: Int, imageIntent: Intent?) {
           super.onActivityResult(requestCode, resultCode, imageIntent)
           // setting the image in image View
           ImageHandler(this).setImageInView(requestCode, resultCode, imageIntent, ivImage)

           if (resultCode == Activity.RESULT_OK) {
               // Get a file to upload to server
               var file = ImageHandler(this).returnFile(requestCode, resultCode, imageIntent)
           }
       }

We also need to override the onRequestPermissionsResult() to handle the permission automatically.

       override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<String>, grantResults: IntArray ) {
    ImageHandler(this).permissionResponse(requestCode, permissions, grantResults)
}

Get image file to upload to server in onActivityResult method

      if (resultCode == Activity.RESULT_OK) {
                         // Get a file to upload to server
                         var file = ImageHandler(this).returnFile(requestCode, resultCode, imageIntent)
                     }

You need to declare the File Provider in androidMainfest.xml as below

          <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="com.example.android.fileprovider.as"
        android:exported="false"
        android:grantUriPermissions="true"
        tools:replace="android:authorities">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"
            tools:replace="android:resource" />
    </provider>

here the android:authorities="com.example.android.fileprovider.as" must be same, as it is used in dependency.

We also need to declare the android:resource="@xml/file_paths" in project in xml folder under Res folder file_paths.xml

        <?xml version="1.0" encoding="utf-8"?>
      <paths xmlns:android="http://schemas.android.com/apk/res/android">
      <external-path name="my_images" path="." />
      </paths>
