Release Note 7.1-r4


The Android-x86 project is glad to announce the release of 7.1-r4, the fourth stable release for Android-x86 7.1 (nougat-x86). The prebuilt images are available in the following sites as usual:

Key Features

The 7.1-r4 is mainly a bugfixes release of 7.1-r3. It based on Android 7.1.2 Nougat MR2 security updates (android-7.1.2_r39). Some features are back-ported from 8.1 release including the newer graphical stack (mesa 18.3.6). We encourage users of 7.1-r3 or older release upgrade to this release.

Released Files

This release contains these files. Except the images built with kernel 4.9 as before (the first four files), we also provide experimental images built with kernel 4.19 (the last two files). If you have newer devices not supported by kernel 4.9, you may try the kernel 4.19 version. Most modern devices should be able to run the 64-bit ISO. For older devices with legacy BIOS, try the 32-bit ISO.

To use an ISO file, Linux users could just dump it into a usb drive to create a bootable usb stick like :

dd if=android-x86-7.1-r4.iso of=/dev/sdX

where /dev/sdX is the device name of your usb drive.

Windows's users can use the tool Win32 Disk Imager to create a bootable usb stick.

In doubt, try the 32-bit files for legacy BIOS devices and 64-bit files for UEFI devices. Please read this page about how to install it to the device.

Except the traditional ISO files, we also package android-x86 files into a Linux package rpm. It allows Linux users to easily install the release into an existing Linux device with a standalone ext4 root partition. On an rpm based device (Fedora/Red Hat/CentOS/SUSE...), just install it like a normal rpm package:

sudo rpm -Uvh android-x86-7.1-r4.x86_64.rpm

This will update your older installation like 6.0-r3 or 7.1-r3 if you have.

On a deb based device (Debian/Ubuntu/LinuxMint/...), please use the alien tool to install it:

sudo apt install alien
sudo alien -ci android-x86-7.1-r4.x86_64.rpm

All files will be installed to the /android-7.1-r4/ subdirectory and boot entries will be added to grub2 menu. Reboot and choose android-x86 item from the menu to boot Android-x86. Alternatively, you can launch Android-x86 in a QEMU virtual machine by the installed qemu-android script:

sudo qemu-android

Note Android-x86 running in QEMU and the real machine (after rebooting) share the same data sub-folder.

To uninstall it :
sudo rpm -e android-x86
or (on Debian/Ubuntu/LinuxMint/...)
sudo apt-get remove android-x86
