Select Image From Gallery

1. Select Single Image from Gallery / Storage

• To take image from gallery into android app we can use already available library

GitHub - ArthurHub/Android-Image-Cropper: Image Cropping Library for Android, optimized for Camera / Gallery.

Image Cropping Library for Android, optimized for Camera / Gallery. - GitHub - ArthurHub/Android-Image-Cropper: Image Cropping Library for Android, optimized for Camera / Gallery.

1. Include the library

dependencies {
    api 'com.theartofdev.edmodo:android-image-cropper:2.8.+'
}

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Using Activity

1. Add CropImageActivity into your AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
  android:theme="@style/Base.Theme.AppCompat"/> <!-- optional (needed if default theme has no action bar) -->

1. Start CropImageActivity using builder pattern from your activity

// start picker to get image for cropping and then use the image in cropping activity
CropImage.activity()
  .setGuidelines(CropImageView.Guidelines.ON)
  .start(this);

// start cropping activity for pre-acquired image saved on the device
CropImage.activity(imageUri)
 .start(this);

// for fragment 
CropImage.activity()
  .start(getContext(), this);

1. Override onActivityResult method in your activity to get crop result
• Deperecated in java

@Deprecated("Deprecated in Java")
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)

        if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
            val result = CropImage.getActivityResult(data)
            if (resultCode == AppCompatActivity.RESULT_OK) {
                val resultUri = result.uri

//            set action to perform on image 

            } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
                val error = result.error
            }
        }
    }

1. Select Image from gallery using intent

1. Using deprecated method

binding.image.setOnClickListener {
        val intent = Intent(Intent.ACTION_GET_CONTENT)
        intent.type = "image//*"   only use one slash
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), 100)
    }


// on class level 
@Deprecated("Deprecated in Java")
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (resultCode == RESULT_OK) {
            if (requestCode == 100) {
                val selectedImageUri = data!!.data
                binding.image.setImageURI(selectedImageUri)

            }
        }
    }

binding.image.setOnClickListener {
      val intent = Intent(Intent.ACTION_GET_CONTENT)
      intent.type = "image//*"   only use one slas
      imageLauncher.launch(intent)
  }

// on class level
private val imageLauncher =
    registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
        if (it.resultCode == RESULT_OK) {
            if (it.data != null) {
                val selectedImageUri = it.data!!.data
                binding.image.setImageURI(selectedImageUri)
            }
        }
    }

2. Select Multiple Images from gallery

// define numbers of images to be selected
private val REQUEST_CODE= 5

// put this on some button 
val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.setType("image/*")    */ //  define type to be selected 

// Important Line to select images 
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true)

startActivityForResult(
  Intent.createChooser(intent, "Select Picture"),
  REQUEST_CODE
)

• Selected File will be get in onActivityResult function

• Now if our REQUEST_CODE match than we can process on data

@Deprecated("Deprecated in Java")
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == REQUEST_CODE) {
            if (resultCode == RESULT_OK) {
                if (data?.clipData != null) {
                    val count = data.clipData!!.itemCount 
											//evaluate the count before the for loop --- otherwise, the count is evaluated every loop.
                    imageUriArray.clear()
                    imageStringArray.clear()
                    for (i in 0 until count) {
                        val imageUri = data.clipData?.getItemAt(i).uri

                        //do something with the image 
												//(save it to some directory or whatever you need to do with it here)
                    }
                }
            } else if (data?.data != null) {
                val imagePath = data.data?.path
                //do something with the image (save it to some directory or whatever you need to do with it here)
            }
        }
    }
