Install Android Studio 2 on Apricity Linux

I want to reinstall android studio on my apricity linux box and as always I need to write the process for my future reference.

Android Studio 2

I use yaourt :

yaourt -S android-studio

Java in Apricity

By default android studio will install openjdk 7 so I ended with 3 version of Java after install Oracle JDK :

yaourt -S jdk

ls /usr/lib/jvm

default  default-runtime  java-7-openjdk  java-8-jdk  java-8-openjdk

Make Oracle JDK for Android Studio as it always give me warning :


“System Health
OpenJDK shows intermittent performance and UI issues. We recommend using the Oracle JRE/JDK.”

Set environment :

sudo nano /etc/environment

and this line :


save. For more detail explanation of switching you can refer to this.

Update :

Java Compiler aka javac

I just realized that javac command return an error :

javac -version

zsh: command not found: javac

Woot 🙂

ls -al /usr/bin | grep javac

lrwxrwxrwx 1 root root 30 Nov 2 2014 javac -> /usr/lib/jvm/default/bin/javac

quick resolv :

sudo rm /usr/bin/javac

sudo ln -s /usr/lib/jvm/java-8-jdk/bin/javac /usr/bin/javac

Testing javac version

javac -version

javac 1.8.0_102

Step by step guide create apk for your ionic framework project

Programmer Gamer Classic White Coffee Mug

I just learn to use ionic framework and I like it since I can use my knowledge in html and css a bit. The process also push me to learn about angular js. As the process getting fun each day I got litttle problem with create apk process (part of publishing). Specially in sign step. I try to recreate it by make simple ‘blank’ project.

Here’s my environment :

$ ionic info

Your system information:

Cordova CLI: 5.3.1
Gulp version:  CLI version 3.9.0
Gulp local:
Ionic CLI Version: 1.6.5
Ionic App Lib Version: 0.3.9
OS: Distributor ID:    Peppermint Description:    Peppermint Five
Node Version: v4.0.0

Create the project

$ ionic start test blank

$ cd test/

$ ionic platform add android

Start process build apk

$ cordova plugin rm cordova-plugin-console

$ cordova build –release android





Total time: 13.138 secs
Built the following apk(s):

Generate Private Key

I use this convention :

keytool -genkey -v -keystore appname.keystore -alias appnamekey -keyalg RSA -keysize 2048 -validity 10000

$ keytool -genkey -v -keystore test.keystore -alias testkey -keyalg RSA -keysize 2048 -validity 10000
Enter keystore password:
Re-enter new password:
What is your first and last name?

What is the name of your organizational unit?
[Unknown]:  digitalfusi
What is the name of your organization?

What is the name of your City or Locality?
[Unknown]:  palembang
What is the name of your State or Province?
[Unknown]:  sumsel
What is the two-letter country code for this unit?
[Unknown]:  id
Is CN=alamsyah rasyid, OU=digitalfusi, O=digitalfusi, L=palembang, ST=sumsel, C=id correct?
[no]:  yes

Sign apk file

1st error :

$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore test.keystore android-release-unsigned.apk test
Enter Passphrase for keystore:
jarsigner: Certificate chain not found for: test.  test must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.

note : I don’t use absolute path for this command.

2nd error :

$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore /home/alamsyah/test/test.keystore android-release-unsigned.apk testkey
Enter Passphrase for keystore:
jarsigner: unable to open jar file: android-release-unsigned.apk

note : I type the command not in the same location of .apk file

$ cd platforms/android/build/outputs/apk/

retype the command

$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore /home/alamsyah/test/test.keystore android-release-unsigned.apk testkey

Optimize apk with zipalign

zipalign is part of jdk. In my case I already install it in /opt

$ pwd
[email protected] /opt/android-sdk/build-tools/23.0.1 $ ls
aapt  arm-linux-androideabi-ld  dexdump  i686-linux-android-ld  jill.jar  llvm-rs-cc      mainDexClasses.rules     NOTICE.txt  split-select
aidl  bcc_compat                dx       jack.jar               lib       mainDexClasses  mipsel-linux-android-ld  renderscript   zipalign

So the correct command is :

$ /opt/android-sdk/build-tools/23.0.1/zipalign -v 4 android-release-unsigned.apk  test.apk
Verifying alignment of test.apk (4)…
50 META-INF/MANIFEST.MF (OK – compressed)

2333704 resources.arsc (OK)
2337101 classes.dex (OK – compressed)
Verification succesful.

That is good sign that apk successfully optimize and ready for google play 🙂

Trying Eclipse on Ubuntu 13.04

I want to try Eclipse on my Ubuntu 13.04 . Installation process is quite straight perhaps useful for me in future use.

Checking Java

I already install Java before, check it first :

$ java -version

java version “1.7.0_25”
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2)
OpenJDK Server VM (build 23.7-b01, mixed mode)

Get nearest mirror from Eclipse website

As I’m from Indonesia I got mirror from University of Indonesia.

$ wget -c

Checking md5 sum against :

bd98e1ac83cbc95909a3c856d3ced8a6  eclipse-standard-kepler-SR1-linux-gtk.tar.gz

$ md5sum eclipse-standard-kepler-SR1-linux-gtk.tar.gz
bd98e1ac83cbc95909a3c856d3ced8a6  eclipse-standard-kepler-SR1-linux-gtk.tar.gz

Good packet.

$ tar xvzf eclipse-standard-kepler-SR1-linux-gtk.tar.gz

Installing Android SDK on Ubuntu Desktop 13.04

I want to learn about Android application and heard about phonegap. Android SDK is a must have before proceed to next step. Here my documentation for install android SDK on my Ubuntu Desktop 13.04 :

Get latest SDK Tools, minimalist is better. I pick SDK Tools only.

After get the link via firefox I decide to use wget :

$ wget -c
$ mv android-sdk_r22.3-linux.tgz /home/alamsyah/
$ cd /home/alamsyah/
$ tar xvzf android-sdk_r22.3-linux.tgz

update path ::

$ export PATH="$HOME/android-sdk-linux/tools:$HOME/android-sdk-linux/platforms:$PATH"

$ echo $PATH


install jdk and  ant

$ sudo apt-get install openjdk-6-jdk ant


Click Install 9 Packages button to continue and get rid of “missing platform tools” error message.


After install remaining packages then the path need to adjust :

Last one need to install related to Android SDK is : android debug bridge
$ sudo apt-get install android-tools-adb

Enough 🙂
