Ubuntu 14.04 Setup Android development environment

Preparing the Java Environment

This article only installs the SDK and does not install any IDE, because I only need to command line mode development.

Install OPENJDK 1.6 first. Then install Ant. This does not repeat.

Download SDK

Download the SDK for Linux 64bit version number here: Http://developer.android.com/sdk/index.html?hl=sk#download

wget http://dl.google.com/android/android-sdk_r23.0.2-linux.tgz

After downloading, unzip to local folder, for example/opt/folder, then environment variable setting, add three lines to ~/.BASHRC file

Export android_home=/opt/android-sdk-linuxpath= $PATH:/opt/android-sdk-linux/toolspath= $PATH:/opt/ Android-sdk-linux/platform-tools

Execute Android SDK Manager

Executes the android command. The SDK Manager dialog box will pop up to select the required package for installation

Installing Analog Devices

Android AVD

Official documentation for the detailed examination: http://developer.android.com/training/basics/firstapp/running-app.html

I created an analog device. The simulation device is finally executed.

Create a project

$ android Create Project--target android-10--name myfirstapp--path myfirstapp--activity mainactivity--package com.exa Mple.myfirstapp> Created Project Directory:myfirstappcreated Directory/home/dean/work/gitlab_cloud/android/ example/myfirstapp/src/com/example/myfirstappadded file myfirstapp/src/com/example/myfirstapp/ mainactivity.javacreated directory/home/dean/work/gitlab_cloud/android/example/myfirstapp/rescreated Directory/ Home/dean/work/gitlab_cloud/android/example/myfirstapp/bincreated directory/home/dean/work/gitlab_cloud/android /example/myfirstapp/libscreated directory/home/dean/work/gitlab_cloud/android/example/myfirstapp/res/ valuesadded file myfirstapp/res/values/strings.xmlcreated directory/home/dean/work/gitlab_cloud/android/example/ myfirstapp/res/layoutadded file myfirstapp/res/layout/main.xmladded file myfirstapp/androidmanifest.xmladded file myfirstapp/build.xmladded file Myfirstapp/proguard-project.txt[email protected]:~/work/gitlab_cloud/android /example$ Lsmyfirstapp readme[email protected]:~/work/gitlab_cloud/android/example$ CD MyFirstApp/[email  protected]:~/work/gitlab_cloud/android/example/myfirstapp$ lsandroidmanifest.xml Ant.properties bin Build.xml Libs L Ocal.properties proguard-project.txt project.properties Res src

Compile

Perform the following command compilation

Ant Debug

Suppose the following error is reported:

     [AAPT]/opt/android-sdk-linux/build-tools/19.0.3/aapt:error while loading shared libraries:libz.so.1:cannot open Shared object File:no such file or directory

Installation Library:

sudo apt-get install lib32z1

Deploying programs to Emulators

$ adb install bin/myfirstapp-debug.apk97 kb/s (4858 bytes in 0.048s) pkg:/data/local/tmp/myfirstapp-debug.apksuccess

The execution of the program is good, now you can execute the program in the simulator. Executes the program mainactivity. The following text is displayed:

Hello World, Mainactivity

The text is actually defined in the./res/layout/main.xml file:

<?xml version= "1.0" encoding= "Utf-8"?
><linearlayout xmlns:android= "http://schemas.android.com/apk/res/android"    android:orientation= " Vertical "    android:layout_width=" fill_parent "    android:layout_height=" fill_parent "    ><textview      android:layout_width= "fill_parent"     android:layout_height= "wrap_content"     android:text= "Hello World, Mainactivity "    /></linearlayout>

Define the application name

Suppose you want to change the name of an app in Android, not edit it in Pom.xml, but define it in Src/values/strings.xml, for example:

<?xml version= "1.0" encoding= "Utf-8"?><resources>    <string name= "App_name" >mvn_example1</ string>    <string name= "Edit_message" >enter a message</string> <string    name= "Button_send" >Send</string>    <string name= "action_settings" >Settings</string>    <string name= " Title_activity_main ">MainActivity</string></resources>
