In some implementations, a computing device can be configured with a hybrid application that includes a native layer and a web view. The native layer can provide access to native features of the computing device while the web view can provide web client features, such as graphical user interfaces and server communication functionality. When the computing device is offline and the hybrid application is invoked, the native layer can load from local storage a resource bundle including the web code needed to present the web view graphical user interface, and/or facilitate communication with the web server. Similarly, when the computing device is offline, the hybrid application can load previously stored content items into the web view from local storage through the native layer so that the user can work with the content items offline. ## Claims ### Claim 1 A method, comprising: executing, by a computing device, a native component of a software application stored in memory of the computing device, wherein the native component is generated using technology native to the computing device and wherein the software application includes a resource bundle having non-native web code defining a web view for the software application; loading, by the computing device, the non-native web code from the resource bundle into the native component to generate the web view; determining, by the computing device, that a network connection to a server device that provides digital assets for the software application is unavailable; obtaining, by the computing device, a digital asset for presenting the web view from local storage on the computing device when the network connection is unavailable, wherein the digital asset comprises web code defining the web view for the software application; and presenting, by the computing device, the web view using the digital asset. ### Claim 2 (depends on 1) The method of claim 1, wherein loading, by the computing device, the non-native web-code from the resource bundle into the native component to generate the web view, comprises: generating a global variable for sending one or more messages between the native component and the web view. ### Claim 3 (depends on 1) The method of claim 1, further comprising: obtaining, by the computing device, a content item list identifying content items locally available; and presenting, by the computing device, the content item list via the web view. ### Claim 4 (depends on 1) The method of claim 1, further comprising: receiving, by the computing device via the web view, user input selecting a content item; obtaining, by the computing system, the content item from the local storage; and presenting, by the computing system, the content item via the web view. ### Claim 5 (depends on 1) The method of claim 1, wherein the digital assets include one or more resources associated with the resource bundle. ### Claim 6 (depends on 1) The method of claim 1, wherein the digital assets include one or more content items associated with the software application. ### Claim 7 (depends on 1) The method of claim 1, wherein the digital assets include web code defining the web view for the software application previously received from the server device. ### Claim 8 A non-transitory computer readable medium including one or more sequences of instructions that, when executed by one or more processors, cause the processors to perform operations comprising: executing, by a computing device, a native component of a software application stored in memory of the computing device, wherein the native component is generated using technology native to the computing device and wherein the software application includes a resource bundle having non-native web code defining a web view for the software application; loading, by the computing device, the non-native web code from the resource bundle into the native component to generate the web view; determining, by the computing device, that a network connection to a server device that provides digital assets for the software application is unavailable; obtaining, by the computing device, a digital asset for presenting the web view from local storage on the computing device when the network connection is unavailable, wherein the digital asset comprises web code defining the web view for the software application; and presenting, by the computing device, the web view using the digital asset. ### Claim 9 (depends on 8) The non-transitory computer readable medium of claim 8, wherein loading, by the computing device, the non-native web-code from the resource bundle into the native component to generate the web view, comprises: generating a global variable for sending one or more messages between the native component and the web view. ### Claim 10 (depends on 8) The non-transitory computer readable medium of claim 8, further comprising: obtaining, by the computing device, a content item list identifying content items locally available; and presenting, by the computing device, the content item list via the web view. ### Claim 11 (depends on 8) The non-transitory computer readable medium of claim 8, further comprising: receiving, by the computing device via the web view, user input selecting a content item; obtaining, by the computing system, the content item from the local storage; and presenting, by the computing system, the content item via the web view. ### Claim 12 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the digital assets include one or more resources associated with the resource bundle. ### Claim 13 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the digital assets include one or more content items associated with the software application. ### Claim 14 (depends on 8) The non-transitory computer readable medium of claim 8, wherein the digital assets include web code defining the web view for the software application previously received from the server device. ### Claim 15 A system comprising: one or more processors; and a non-transitory computer readable medium including one or more sequences of instructions that, when executed by one or more processors, cause the processors to perform operations comprising: executing, by a computing device, a native component of a software application stored in memory of the computing device, wherein the native component is generated using technology native to the computing device and wherein the software application includes a resource bundle having non-native web code defining a web view for the software application; loading, by the computing device, the non-native web code from the resource bundle into the native component to generate the web view; determining, by the computing device, that a network connection to a server device that provides digital assets for the software application is unavailable; obtaining, by the computing device, a digital asset for presenting the web view from local storage on the computing device when the network connection is unavailable, wherein the digital asset comprises web code defining the web view for the software application; and presenting, by the computing device, the web view using the digital asset. ### Claim 16 (depends on 15) The system of claim 15, wherein loading the non-native web-code from the resource bundle into the native component to generate the web view, comprises: generating a global variable for sending one or more messages between the native component and the web view. ### Claim 17 (depends on 15) The system of claim 15, wherein the instructions further cause the processors to perform operations comprising: obtaining a content item list identifying content items locally available; and presenting the content item list via the web view. ### Claim 18 (depends on 15) The system of claim 15, wherein the instructions further cause the processors to perform operations comprising: receiving, via the web view, user input selecting a content item; obtaining the content item from the local storage; and presenting the content item via the web view. ### Claim 19 (depends on 15) The system of claim 15, wherein the digital assets include one or more resources associated with the resource bundle. ### Claim 20 (depends on 15) The system of claim 15, wherein the digital assets include one or more content items associated with the software application.
