Comment

This post show how to Download and install Android Studio 3.0 Canary 1 on 64-bit Ubuntu 17.04, over Windows 10/Oracle VirtualBox,

Firstly, Install Ubuntu 17.04 on Windows 10/Oracle VirtualBox.

Before install Android Studio on 64-bit Ubuntu 17.04, install 32-bit libraries:
$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386

(details refer to Fix "Unable to run mksdcard SDK tool" when install Android Studio on Linux)

Download Android Studio 3.0 Canary, visit https://developer.android.com/studio/preview/index.html
Unpack the ZIP file, to any directory you want.

Setup for debugging on real device:

On Ubuntu/Linux, to debug on real device, you have to set up your system to detect your device.
(referencec: https://developer.android.com/studio/run/device.html#setting-up)

Edit/Create /etc/udev/rules.d/51-android.rules
$ sudo nano /etc/udev/rules.d/51-android.rules

Add the code:
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"

Where 00b4 is the vendor ID, replace it to match your device. For my Samsung device, replace with 04e8.

You can check your USB vendor ID here: https://developer.android.com/studio/run/device.html#VendorIds.

or try to find it using lsusb command.

Fix "Unable to run mksdcard SDK tool" when install Android Studio on Linux

Comment

If you install Android Studio on 64-bit Linux and reported with error:
Unable to run mksdcard SDK tool

Most probably some 32-bit libraries are missed.

If you are running a 64-bit version of Ubuntu, you need to install some 32-bit libraries with the following command:
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 lib32bz2-1.0

If you are running 64-bit Fedora, the command is:
sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686

reference: Troubleshoot Android Studio - Linux libraries

When I try to install the 32-bit libraries on Ubuntu 16.04.2 LTS (64-bit) on VirtualBox with the command:

$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 lib32bz2-1.0

The errors reported:
E: Unable to locate package lib32bz2-1.0
E: Couldn't find any package by glob 'lib32bz2-1.0'
E: Couldn't find any package by regex 'lib32bz2-1.0'

To fixed it, add 32 bit architecture with the command:

$ sudo dpkg --add-architecture i386

$ sudo apt-get update

Re-install with the command

$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386

Done:

Android Studio.how to PdfRenderer

IOException: not create document. Error

Comment

When I prepare the example "Display PDF in assets folder (inside APK)", I face with the error of "java.io.IOException: not create document. Error". It should be generated by the code:

pdfRenderer = new PdfRenderer(fileDescriptor);

Somebody commented it's caused by new version of Gradle (ref: https://github.com/googlesamples/android-PdfRendererBasic/issues/1), so I edit dependencies of buildscript in build.gradle (Project: ...), use gradle:2.1.2 to solve this problem.
