Support 64bit platforms such as arm64-v8a

[GoogleCodeExporter]

ndk-build jni files with android-ndk-r10d on MacPro 10.10.
with APP_ABI := all,but [arm64-v8a] complains error:
chackerskeyboard/java/jni/jni/org_pocketworkstation_pckeyboard_BinaryDictionary.
cpp:53:19: error: cast from 'latinime::Dictionary*' to 'jint {aka int}' loses 
precision [-fpermissive]
     return (jint) dictionary;

seems to cast 64bit pointer to 32bit pointer.

I also encountered this problem when I tried to build the native code. I'm 
using Eclipse Juno and android-ndk-r10e on a Windows 7 (64 bit) machine.

Indeed, the code assumes 32bit pointers.

I've just submitted an untested patch that attempts to fix this by upgrading 
the opaque pointer type to "long", can you give this a try and let me know if 
it works?

Thanks for the speedy reply.

Yep that worked. I no longer have errors during build.  However, suggested 
words are still not displaying. In the version I downloaded from the PlayStore, 
HK pops up suggested words when I start typing. It doesn't happen with my 
built-from-source HK. Thanks in advance.

Can you check if it logs any warnings on startup, i.e. via "adb logcat"? It 
should log "loaded jni_pckeyboard" and "Loaded dictionary, len=..." on success.

There's "loaded jni_pckeyboard" but there's no "Loaded dictionary, len=..." No 
warnings.

Do you have the English dictionary downloaded?

Building from source doesn't include the defalt English dictionary. I intend to 
not include it by default, but have not removed it yet from published builds to 
avoid surprises for people upgrading it.

I didn't download any dictionary. I'm just curious how come I have words being 
suggested to me (PlayStore HK) opposed to my self-compiled that didn't. 
Anyways, thank you for your help. Even without a dictionary, your keyboard is 
still the best there is. Thanks again and keep up the good work.

The Play Store version of Hacker's Keyboard embeds the English dictionary to 
maintain backwards compatibility with earlier versions, while other languages 
still need to be downloaded separately.

If you build your own, the build won't include any dictionary, so you need to 
download the English dictionary to make it work.

Hi, sorry for the super late reply. Anyways, I tried your suggestion (custom HK 
+ English dictionary from PlayStore) and it worked perfectly in my devices. 
Thank you so much for your help and looking forward to more enhancements for 
this amazing keyboard. :)
