* Android's drawable folder.
|
|
*
|
|
* However, keep in mind that React Native Packager does not guarantee that the
|
|
* image exists. If the image is missing you'll get an empty box. When adding
|
|
* new images your app needs to be recompiled.
|
|

|
|
* Prefer Static Image Resources system which provides more guarantees,
|
|
* automates measurements and allows adding new images without rebuilding the
|
|
* native app. For more details visit:
