+Call this method to run CropImage activity
+```java
+private void runCropImage() {
+
+    // create explicit intent
+    Intent intent = new Intent(this, CropImage.class);
+
+    // tell CropImage activity to look for image to crop 
+    String filePath = ...;
+    intent.putExtra(CropImage.IMAGE_PATH, filePath);
+
+    // allow CropImage activity to rescale image
+    intent.putExtra(CropImage.SCALE, true);
+
+    // if the aspect ratio is fixed to ratio 3/2
+    intent.putExtra(CropImage.ASPECT_X, 3);
+    intent.putExtra(CropImage.ASPECT_Y, 2);
+
+    // start activity CropImage with certain request code and listen
+    // for result
+    startActivityForResult(intent, REQUEST_CODE_CROP_IMAGE);
+}
+```
+
+Waiting for result
+```java
+@Override
+protected void onActivityResult(int requestCode, int resultCode, Intent data) {
+
+    if (resultCode != RESULT_OK) {
+
+        return;
+    }  
+
+    switch (requestCode) {
+
+        case REQUEST_CODE_CROP_IMAGE:
+
+            String path = data.getStringExtra(CropImage.IMAGE_PATH);
+
+            // if nothing received
+            if (path == null) {
+
+                return;
+            }
+
+            // cropped bitmap
+            Bitmap bitmap = BitmapFactory.decodeFile(mFileTemp.getPath());
+
+            break;
+    }
+    super.onActivityResult(requestCode, resultCode, data);
