+ *    file="app/src/main/AndroidManifest.xml"
+ *    mode="merge"
+ *    target="/manifest/application">
+ *    <application android:largeHeap="true" />
+ *  </edit-config>
+ * </platform>
+ * ```
+ *
+ * @usage
+ * ```typescript
+ * import { Chooser } from '@ionic-native/chooser';
+ *
+ *
+ * constructor(private chooser: Chooser) { }
+ *
+ * ...
+ *
+ *
+ * this.chooser.getFile()
+ *   .then(file => console.log(file ? file.name : 'canceled'))
