    <p>In my understanding, the NDK simply allows you to program games (and apps if you wanted to) in C/C++ for Android. The code is compiled to Android machine code, not converted into Java in some way. It's questionable whether there's really a huge performance difference on modern phones however.</p> <p>The big advantage of the NDK that hasn't been mentioned here is that it allows you to utilize OpenGL ES 2.0 on older Android versions rather than being stuck with 1.1 if you use Java. OpenGL ES 2.0 has been included in the Java SDK in <del>Gingerbread</del> <em><strong>EDIT: Actually it's Froyo not Gingerbread, as Leif Andersen pointed out in the comments</strong></em>, but at least at the moment, <del>Gingerbread is not widely available</del> Froyo is only on about 60% of Android phones (though that will continue to grow in the next few months).</p> <p>The other huge advantage to the NDK is the ability to port iOS games (and games from some other platforms) that are written in C/C++.</p> <p>If you're fine with using OpenGL ES 1.1, or want to use 2.0 but are fine targeting <del>Gingerbread</del> Froyo and above, and you aren't doing any iOS or other platform ports, then Java is going to almost definitely be the best solution for you. That is unless you're a seasoned C/C++ programmer, then you may be more comfortable programming using the NDK.</p> <p>Also, another advantage to programming in Java is that if there are eventually x86 devices or other chips running Android, your game will still play fine. With NDK it would have to be specially compiled to run on those different chips.</p>

    1. CO"or want to use 2.0 but are fine targeting Gingerbread and above", actually, it's froyo or above, but does require an NDK hack, as demonstrated by this google io talk: http://www.google.com/events/io/2011/sessions/3d-graphics-on-android-lessons-learned-from-google-body.html . Also, I believe the latest version of the NDK (r5) can compile to x86 as well.

    2. COYou are absolutely correct, somehow I got it in my head that it was Gingerbread, but it is in fact Froyo. And regarding the NDK and x86, I didn't mean it couldn't be compiled for other architectures, I just meant that if you compile and upload it for ARM, then if other architectures are used in the future it would need to be recompiled for them rather than just working out of the box. Or are you saying it makes come kind of universal ARM/x86 binary?

    3. COWell, it's not universal in the sense of being some magical bytecode that all three platforms can understand, I'm not sure how that would work. But it does store a version of the library for all three platforms, and if it doesn't happen by default the line: "APP_ABI := armeabi armeabi-v7a x86" in the Application.mk file should trigger it, according the the docs: http://developer.android.com/sdk/ndk/index.html , although admittedly the library I'm currently working on vomits when I do that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
