Development tips

On android for the type it is required to request permissions to read/write. You can get more information in PermissionsAndroid section from react native or Request App Permissions from android documentation. Demo project provides an example how to implement it using Java, check the MainActivity.java and AndroidManifest.xml files.

Before trying type in demo project, open folder in and store some document that you want to render.

On iOS, when using resource you can specify where to look for the file with . If you do not pass any value, the component will lookup in two places. First, it will attempt to locate the file in the Bundle. If it cannot locate it there, it will search the Documents directory. For more information on the iOS filesystem access at runtime of an application please refer the official documentation. Note here that the resource will always need to be a relative path from the Documents directory for example and also do NOT put the scheme in the path (so no ).

You can find an example of both usage of the Bundle and Documents directory for rendering a pdf from on iOS in the demo project.

In demo project you can also run the simple server to serve PDF file. To do this navigate to and start the server . (Do not forget to set proper IP adress of the server in )
