dependencies {
  compile 'com.wajahatkarim3.LongImageCamera:LongImageCamera:1.0.1'
}

Or add LongImageCamera as a new dependency inside your pom.xml

<dependency>

Launch Camera Activity

Start the camera from any Activity with this code:

// Launches camera in Vertical Merge Mode (Captured image will be long)
LongImageCameraActivity.launch( myActivity );

// Launches Camea in Horizontal Merge Mode (Captured image will be wide)
LongImageCameraActivity.launch( myActivity, LongImageCameraActivity.ImageMergeMode.HORIZONTAL );

and then you will get the result image in onActivityResult() method like this:

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

        if (resultCode == RESULT_OK && requestCode == LongImageCameraActivity.LONG_IMAGE_RESULT_CODE && data != null)
        {
            String imageFileName = data.getStringExtra(LongImageCameraActivity.IMAGE_PATH_KEY);
            Log.e(TAG, "onActivityResult: " + imageFileName );
        }
    }

Launch Image Viewer Activity

This library comes with a built-in image viewer including support of pinch/fling gestures for zoom/move/roate etc. You can launch image viewer with this code:

Intent ii = new Intent(myActivity, PreviewLongImageActivity.class);
ii.putExtra("imageName", myImagePath);
startActivity(ii);

You can use customized ImageView with support of gestures for zoom/move/rotate etc like this:

<com.wajahatkarim3.longimagecamera.TouchImageView
        android:id="@+id/imageView1"
