Interacting with Java from the Native Side

IT

http://www.math.uni-hamburg.de/doc/java/tutorial/native1.1/implementing/index.html

Call Java class methods

jmethodID mid = (env)->GetMethodID(cls, “callback”, “()V”);
if (mid == 0) {
return (env)->NewStringUTF(buff);
}
(env)->CallVoidMethod(thiz, mid);

 Make a Jclass global reference, lifetime == app life

cls = (*env)->NewGlobalRef(env, cls1);
        if (cls == 0) {
            ... /* error */      
        }

Remember to free the reference when finish DeleteGlobalRef

Android Wear Developer Preview

IT

Thank you for signing up for the Android Wear Developer Preview.

 

To begin developing on Android Wear, you’ll need the Preview Support library and the Android Wear Preview app for your mobile device. Follow these steps:

 

  • Download the Preview Support library and samples.

  • Opt-in to become a tester of the Android Wear Preview app in the Google Play Store. After opt-in, it could take up to 24 hours for the Android Wear Preview app to be accessible to you in Google Play. Make sure the opt-in user account is the same user signed in to Google Play.

 

Refer to the Android Wear Developer Get Started page for details. Since this is a preview release, please do not publicly distribute apps built with the Preview library. Also note that the APIs are potentially subject to change and you will need to modify your apps when they are released out of preview.

 

Share your experiences and ask questions by joining the Android Wear Developers Google+ Community. We look forward to seeing how your apps take advantage of these new APIs to provide innovative new user experiences!

<uses-sdk android:minSdkVersion=”9″ />

  • Native Code CPU Architecture Used Compatible Android Platform(s)
    ARM, ARM-NEON Android 1.5 (API Level 3) and higher
    x86 Android 2.3 (API Level 9) and higher
    MIPS Android 2.3 (API Level 9) and higher

    These requirements mean you can use native libraries produced with the NDK in applications that are deployable to ARM-based devices running Android 1.5 or later. If you are deploying native libraries to x86 and MIPS-based devices, your application must target Android 2.3 or later.

  • To ensure compatibility, an application using a native library produced with the NDK must declare a <uses-sdk> element in its manifest file, with an android:minSdkVersion attribute value of “3” or higher. For example: 
    <manifest>
  <uses-sdkandroid:minSdkVersion="3"/>
  ...
</manifest>

Want to share Web pages that have content to myself and edit (comment, reorgnize it)

When post a photo, should allow small size photo right to phone size, and allow add comment, links.

Why do peope who want to edit it must register? I can share it with anyone, and they can freely edit it they way they want. but I will keep my version, and I can see other’s version.
