Impossible to launch any SDK Demos APP on Android

[lbstephane]

Hi,

I'm trying to implement your SDK and to learn how it works, I try to use demos, i say i try cos :

- NDK compilation seems to be ok
- importing the project in eclipse work
- Entering the trial serial number in WrapPDFFunc.java is done
- copying the readme.pdf in /mnt/sdcard on my device is ok

Build, when I launch the app on my device, the app crash.

Lauching adb logcat in a terminal command return this :

E/AndroidRuntime(17661): Process: com.foxitsample.view_navigation, PID: 17661

Dear Stephane,

Go to FoxitEmbeddedSDKforAndroid2.1.23354.1092.101412.17 12_enu\examples\demos\demo_view_navigation\src\Fox itEMBSDK\EMBJavaSupport.java

and locate

static{
System.loadLibrary("fpdfembedsdk");
}

and add the following line to load stlport_shared.

static{
System.loadLibrary("stlport_shared");
System.loadLibrary("fpdfembedsdk");
}

Note: make sure Application.mk file defines APP_STL := stlport_shared when building the ndk layer.

Sincerely,
Huy
