Abstract: Techniques to bypass system context checks to facilitate opening shared-object libraries are disclosed herein. In at least one implementation, a copy of a header of a shared-object library loaded by a runtime system is created. The header of the shared-object library loaded by the runtime system is patched with code configured to call an open function, wherein the code patched into the header of the shared-object library executes and calls the open function from the shared-object library loaded by the runtime system, the call to the open function is recognized as within a context of the runtime system, and the shared-object library is allowed to be opened. A pointer to the shared-object library opened in memory is received, and the header of the shared-object library is restored to an original version using the copy of the header of the shared-object library.

Abstract: Techniques to facilitate prevention of just-in-time (JIT) translations of application functions are disclosed herein. In at least one implementation, a JIT translation function of an operating system is modified in memory to redirect the JIT translation function to execute alternative code when the JIT translation function is called. When the JIT translation function is called for an application function, the alternative code is executed to determine whether the application function has been modified. When the alternative code determines that the application function has been modified, the JIT translation function is prevented from translating the application function into a native machine code version. When the alternative code determines that the application function has not been modified, the JIT translation function is allowed to translate the application function into the native machine code version.

Abstract: Techniques to facilitate provision of different user experiences to different groups of users of a mobile application are disclosed herein. In at least one implementation, a manifest provided by an application development and optimization platform is received that defines a plurality of user segments and a plurality of feature variants individually associated with the plurality of user segments. The manifest is processed to determine a segment of the plurality of user segments associated with a user of the mobile application along with a feature variant of the plurality of feature variants associated with the segment of the user. Execution of the mobile application is monitored for an occurrence of an event that triggers a default feature of the mobile application, and responsive to the event, the default feature is replaced with the feature variant associated with the segment of the user.

Abstract: Techniques to facilitate modification of content displayed in a webview embedded into a mobile application are disclosed herein. In at least one implementation, webview modification instructions provided by an application development and optimization platform are received that indicate modified webview content associated with a uniform resource identifier (URI) accessed by the mobile application in the webview. Execution of the mobile application is monitored for an occurrence of an event that triggers loading of the URI in the webview of the mobile application. Responsive to the event, the webview modification instructions are executed to present the modified webview content in the webview of the mobile application.

Abstract: Techniques are described herein for enhancing software application development and software design-for-test (DFT) technology by facilitating dynamic management and control of embedded dynamic test features via an application development and optimization platform. In some embodiments, an application development and optimization platform is described that can track, manage and rollout features of native mobile applications without the need to wait for public app store releases.
