libqi crash on android

[lenLRX]

I'm trying to build a app with libqi and it crash at the code below.
Application app = new Application(args);
I am using libqi-master libqi-java-master on Android 4.4.2 .
And the permissions are
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/> <uses-permission android:name="android.permission.READ_OWNER_DATA"/> <uses-permission android:name="android.permission.CLEAR_APP_CACHE"/> <uses-permission android:name="android.permission.WRITE_OWNER_DATA"/>

Then I found the tombstone

So I think that maybe some uncaught execption (boost::filesystem::filesystem_error) cause the crash.

I tried to read the code of libqi and i found there many function may throw an exception out of try{};

Maybe next step I should try to catch these excption in qimessaging-jni.so and rethrow them to the java side thus I can use System.out.println to show them on the log-cat.(is that possible to catch a exception in anothor library? )

Now I caught exception and is says that

boost::filesystem::status: Permission denied: "/sbin/java"

why does libqi want to access "/sbin/java"?
