ROM Manager and Clockwork Recovery Image

ROM Manager is a Android front end to the Clockwork Recovery image.

Features of the recovery image include Nandroid backup, adb shell, mount USB storage, advanced update.zip options (ignore asserts and signature checks), and file browser (so you can place your zips in subdirectories and organize them).


The easiest way, by far, to install the recovery is by downloading ROM Manager off the market. But for those that would prefer a manual installation, you can grab the APK and recovery image below.

And of course, all the source can be found on Github.

Working Vendor Configuration for Motorola Sholes (Droid)

I had a spare Droid (two actually) sitting on my desk at work, so I spent some time hacking up a working vendor configuration for the phone. Took me a few days, but it all worked! I ended up flashing Android 2.1r2 to it.

Happy Hacking! Head on over to my sholes-open Github repository.

Klaxon 4.0 for Android

Klaxon for Android has gone through another rigorous update! This time, I integrated the new Desk Clock from Eclair (Nexus One) into the application. The result is the customizability of Klaxon that users have come to love, with a brand spanking new and polished UI.

For those of you curious how to get the Weather widget on your desk clock, Google “genie widget” for the third party application found on the Nexus One.

 

Android.dll

Picture above represents the results of 3 sleepless nights. No, I didn’t rewrite the Android framework. I generated a bunch of proxy classes to access them from Mono though. Rough idea of how it works:

1. Java application reflects through Android framework SDK jar and outputs an XML file that represents the object model.
2. C# application generates thousands of code files of said object model. (This is similar to jni4net, but that doesn’t work on anything but Windows).
3. Tag all the methods with the [MethodImpl(MethodImplOptions.InternalCall)] attribute.
4. Implement the method calls at runtime with a combination of dynamically created expression tree delegates and mono_add_internal_call.

The class contents actually have no code, so the total dll size is pretty small (800k). Here’s what the LinearLayout “implementation” looks like:

    public class LinearLayout : android.view.ViewGroup
    {
