I want it to be something like this.

editButton.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent goEdit;
            goEdit = new Intent(PreviewActivity.this, CropImage.class);
            goEdit.putExtra("image-path", path);
            goEdit.putExtra("scale", true);
            goEdit.putExtra("fileName", nameFromPath);
            //finish();
            checkEdit = true;
            startActivityForResult(goEdit,0);

        }
});

EDIT I use this button listener to call into the cropImage file by calling to the class CropImage activity. This is a custom intent not the crop feature inside android but I think is the copy of it so that make it support for all versions but when I call into it the selected area isnt brighten and I donno where is the problem can anyone guide me? Thanks This is the library I'm using drioid4you crop image

Can you use default android Crop functionality?

Here is my code

private void performCrop(Uri picUri) {
    try {
        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        // indicate image type and Uri
        cropIntent.setDataAndType(picUri, "image/*");
        // set crop properties here
        cropIntent.putExtra("crop", true);
        // indicate aspect of desired crop
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        // indicate output X and Y
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);
        // retrieve data on return
        cropIntent.putExtra("return-data", true);
        // start the activity - we handle returning in onActivityResult
        startActivityForResult(cropIntent, PIC_CROP);
    }
    // respond to users whose devices do not support the crop action
    catch (ActivityNotFoundException anfe) {
        // display an error message
        String errorMessage = "Whoops - your device doesn't support the crop action!";
        Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
        toast.show();
    }
}

declare:

final int PIC_CROP = 1;

at top.

In onActivity result method, writ following code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PIC_CROP) {
        if (data != null) {
            // get the returned data
            Bundle extras = data.getExtras();
            // get the cropped bitmap
            Bitmap selectedBitmap = extras.getParcelable("data");

            imgView.setImageBitmap(selectedBitmap);
        }
    }
}

It is pretty easy for me to implement and also shows darken areas.

This library: Android-Image-Cropper is very powerful to CropImages. It has 3,731 stars on github at this time.

You will crop your images with a few lines of code.

1 - Add the dependecies into buid.gradle (Module: app)

compile 'com.theartofdev.edmodo:android-image-cropper:2.7.+'

2 - Add the permissions into AndroidManifest.xml

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

3 - Add CropImageActivity into AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
 android:theme="@style/Base.Theme.AppCompat"/>

4 - Start the activity with one of the cases below, depending on your requirements.

// 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 (DO NOT use `getActivity()`)
CropImage.activity()
.start(getContext(), this);

5 - Get the result in onActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
    CropImage.ActivityResult result = CropImage.getActivityResult(data);
    if (resultCode == RESULT_OK) {
      Uri resultUri = result.getUri();
    } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
      Exception error = result.getError();
    }
  }
}

You can do several customizations, as set the Aspect Ratio or the shape to RECTANGLE, OVAL and a lot more.
