Set Android development environment in Ubuntu 14.04

Prepare the Java environment

This article only installs the sdk and does not install any IDE, because I only need to develop it in command line mode.

First install openjdk 1.6 and then install ant.

Download SDK

Download SDK for Linux 64bit from here: http://developer.android.com/sdk/index.html? Hl = sk # download

After the download, decompress the package to the local directory, such as the/opt/directory, set the environment variables, and add three lines ~ /. Bashrc File

export ANDROID_HOME=/opt/android-sdk-linuxPATH=$PATH:/opt/android-sdk-linux/toolsPATH=$PATH:/opt/android-sdk-linux/platform-tools

Run Android SDK Manager

Run the android command. The SDK Manager dialog box is displayed, from which you can select the required package for installation.

Install a simulated Device

android avd

For more information, see the official documentation: http://developer.android.com/training/basics/firstapp/running-app.html

I created a simulated device for my moto680 instance. Finally, run the simulated device.

Create project display targets

Create a project

$ android create project --target android-10 --name MyFirstApp \--path MyFirstApp --activity MainActivity --package com.example.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.txtdean@dean-Aspire-V7-481G:~/work/gitlab_cloud/android/example$ lsMyFirstApp  READMEdean@dean-Aspire-V7-481G:~/work/gitlab_cloud/android/example$ cd MyFirstApp/dean@dean-Aspire-V7-481G:~/work/gitlab_cloud/android/example/MyFirstApp$ lsAndroidManifest.xml  ant.properties  bin  build.xml  libs  local.properties  proguard-project.txt  project.properties  res  src

Compile

Run the following command to compile

ant debug

Deploy the program to the simulator

$ adb install bin/MyFirstApp-debug.apk97 KB/s (4858 bytes in 0.048s)pkg: /data/local/tmp/MyFirstApp-debug.apkSuccess

After running the program, you can run the program in the simulator. Run the MainActivity program to display the following text:

Hello World, MainActivity

This 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>
