I want to use the native code(NDK) to capture the camera data, so I use the function openCameraHardware() to create a new CameraHardwareInterface, Create Instance OK, but when InitParameter it returns error, the logcat like this :

V/QualcommCameraHardware( 840): openCameraHardware: call createInstance V/QualcommCameraHardware( 840): createInstance: E V/QualcommCameraHardware( 840): constructor EX V/QualcommCameraHardware( 840): setParameters: E params = 0xbeedc298 V/QualcommCameraHardware( 840): requested size 480 x 320 V/QualcommCameraHardware( 840): actual size 480 x 320 V/QualcommCameraHardware( 840): initCameraParameters: E V/QualcommCameraHardware( 840): loading libqcamera V/QualcommCameraHardware( 840): waiting for REX to initialize.

Load PDF file from the assets directory

Is there any way to load a PDF file from the assets directory programmatically?
