We know android-x86 support Houdini, so we will download Houdini files from android-x86 page. We just need to inherit nativebridge.mk in our emulator device.mk to add libnb to ourĮmulator system, as following showing: $(call inherit-product-if-exists,device/generic/common/nativebridge/nativebridge.mk)
System/bin, setting native bridge abi list, and etc.īin contains a script called enable_nativebridge, and it will be executed when user Natibridge.mk defines the product definition for Houdini, such as copying enable script to The system can work without libhoudini and with libhoudini, it creates the module libnb When the user enables it, it will trigger init toĭownload Houdini from its download page, and mount it to system to use it. The Android.mk and src defines the module libnb, what is the wrapper of libhoudini.Īndroid-x86 doesn’t provide Houdini in its source code, and it provides a switch button in device/ibm/thinkpad/ OEMBlackList OEMWhiteList ThirdPartySO bin nativebridge.mk src Add the following line to $AOSP/device///system.prop (e.g. git apply -v /libhoudini-patch-and-binaries/jb-houdini.patchĦ. Copy the contents of /libhoudini-patch-and-binaries/system/lib to $AOSP/out/target/product//system/libĥ. Download and unarchive libhoudini-patch-and-binaries.tgz.ģ.

Have the AOSP project source code download and the build environment all setup. I just test against a branch based on the 4.2.2 tree so I can't say how well it'll work on other versions.ġ.
ANDROID X86 ARM EMULATOR HOW TO
So on to the fun stuff, the instructions on how to get libhoudini installed and configured on Android x86. That work was done by the BuilDroid project which seems to have changed names to AndroVM and now Genymotion (a great online Android Emulator that allows you to choose a range of device types, resolution types, Android versions etc). Intel must've provided their binaries to Lenovo for release. From what I gather the original libhoudini libraries were ripped from a Lenono K900 device that runs x86 hardware. The information on the internet is really sparse and there's a lot of broken links so I'm hoping this blog article will stay around for a while and be helpful to some. libhoudini is a Binary Translator (translates ARM ABI to x86 ABI) developed by Intel and is close sourced. This is done with a little library called Houdini. critical/normal programs run fast) and the code that is only available in ARM compiled binaries is translated real-time into instructions your x86 CPU can understand. With Android x86, most of the code is executed natively (i.e. From what little research I've done into the Android Emulator itself, I believe the entire OS is ARM based so there's a tonne of constant emulation that needs to be done, hence the major performance cost. So where does that leave us? You emulate ARM architecture on your x86 hardware. Many developers maybe unaware of this feature, and I'm sure some developers are just not aware that x86 versions of Android devices are emerging more and more.

Google Play does apparently allow you to have a separate APK for each architecture so you won't need to worry about having a few useless-to-the-many MBs of x86 code in the APK that your ARM users install. Most will at least compile for ARM but in the interest of cutting down on the size of the APK a lot skip x86 and others (MIPS etc). When developers prepare an app for release they can choose what architecture(s) to compile their native library binaries for. But the fact is a lot of apps also have native libraries built into them (compiled using the NDK and written usually in C or C++). The majority of apps will function fine as well, at least if they're 100% written in Java.

Yes, that's right - you can run native Android on your PC or Mac! No more horrendously slow Android Emulator.Īndroid x86 runs super fast on most bits of Intel hardware. For those of you who don't know it's a project to get Android running on various Intel x86 architecture based platforms based of the vanilla Android Open Source Project from Google. These past few months I've being playing with a customized flavour of Android x86 and virtualization (I'm loving OpenStack!). It's been a busy one at that! Feel free to skip to the bottom if you just want the instructions on how to get libhoudini running on Android x86.
