Why would I want to have the Android Emulator? Well, I needed to test several custom Android Packages and also develop apps for Android. This meant, I could keep testing the Android Packages without having to install on a physical Android phone such as the Sony Ericsson X10 or Samsung S3.
I have written on this topic for Centos 64bits, before and seems like it still depends on 32bit libraries:
A good reference for everything Android is at http://developer.android.com/sdk/index.html
Here are steps for Centos 6.4 (64bits), open up a terminal as root;
Step 1: Install Java development kit (JDK)
# yum update
# yum install java-1.7.0-openjdk-devel.x86_64
Verify installation with following command:
# javac -version
Step 2a: Install library for 32bits
yum install glibc.i686 ncurses-libs.i686 libstdc libstdc++.i686 libzip.i686 SDL.i686 gegl.i686 mesa-libGL.i686
Note: Optional package to install:
Step 2: Install the Android SDK and ADT
Get the latest Android ADT from the Android Developer site or use following:
This will provide us with (Size if 440MB):
- Eclipse + ADT plugin
- Android SDK Tools
- Android Platform-tools
- The latest Android platform
- The latest Android system image for the emulator
Allow groups named devel to access development. Create the directory /opt/android and extract adt-bundle-linux-x86_64-20130729.zip
# mkdir /opt/android
# useradd -m devel
# chown devel.devel /opt/android
# chmod g+rwsx,+t /opt/android
# unzip -d /opt/android/ adt-bundle-linux-x86_64-20130729.zip
Step 3: Post installation.
What can we do after installation? Well, you can run the Eclipse IDE to develop application and there is also the Android Emulator (to test APK). Info on the Android Emulator can be found at http://developer.android.com/tools/devices/emulator.html
I suggest that you login as the devel user or a user with that group access to continue (Represented as $ in steps below).
Start Eclipse with
Starting with the emulator
1. Listing the available emulators
$ cd /opt/android/adt-bundle-linux-x86_64/sdk/tools
$ ./android list targets
Available Android targets:
id: 1 or "android-18"
Name: Android 4.3
API level: 18
Skins: WSVGA, WVGA800 (default), WVGA854, WQVGA432, WQVGA400, WXGA800, QVGA, WXGA720, HVGA, WXGA800-7in
ABIs : armeabi-v7a
Here it is called practiceandroid4.3 with the target id 1 (as above). Items in RED are optional. For further details see http://developer.android.com/tools/devices/managing-avds-cmdline.html
$ android create avd -n practiceandroid4.3 -t 1 --skin WVGA800
$ emulator -avd practiceandroid4.3
APK can be installed into the Android emulator
$ adb install bin/MyFirstApp-debug.apk
- If there is a problem running Eclipse or the Emulator, try the Step 2a above.
- For error "./emulator: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory", ensure the step 2a is done.
- When upgrade Centos 6.3 to Centos 6.4 on Virtualbox, it hangs at the boot progress bar. Fix is at http://bugs.centos.org/view.php?id=6306
