I. Prepare ant and android
1. Decompress ant and android downloaded from the official website to your local device.
2. Set ANT_HOME and ANDROID_HOME in environment variables, such as: F: \ software \ apache-ant-1.9.3, F: \ android \ adt-bundle-windows-x86-20140321 \ sdk
3. Add % ANT_HOME % \ bin and % ANDROID_HOME % \ bin to path
Note: ANT_HOME and ANDROID_HOME must be configured, because we will use build. xml
2. Add an ant environment for a project (such as the Project name WebView)
Run the doscommand to enter the project root path, for example, cd F: \ workspace_android \ WebView. Run the following command:
Android update project -- name WebView-t 2-p F: \ workspace_android \ WebView
After this command is run, build. xml is added to the project path.
-- Name must be available, followed by the Project name
-P indicates the project path
-T indicates the target version, that is, the target id of android. Run the "android list target" command to view the target id:
Id: 1 or "android-18"
Name: IOS 4.3
...
Id: 2 or "android-19"
...
We can see that id 2 represents the android-19 version.
3. Release a project
You can run the ant release or ant clean release command (recommended). If you do not run the clean command to directly release ant release, the release may fail.
This command will be based on the ant. properties to find the key. If ant is not found. properties to publish an unsigned apk file, but the unsigned apk cannot be installed on the mobile phone.
So we need to create the ant. properties file with the following content:
Key. store = android. keystore
Key. alias = android. keystore
Key. store. password = 123456
Key. alias. password = 123456
This content is for android. if there is no keystore key, we need to create it first. Google recommends that this key be created only once, because data sharing may be required for multiple apps we develop.
The command to generate the keystore is as follows:
Keytool-genkey-alias android. keystore-keyalg RSA-validity 20000-keystore android. keystore
Then, enter the key password and organization information:
Enter the keystore password: 123456
Enter the new password again: 123456
What is your first name and last name?
[Unknown]: zhang biao
What is the name of your organization?
[Unknown]: **
What is your organization name?
[Unknown]: **
What is the name of your city or region?
[Unknown]: shenzhen
What is the name of your province/city/autonomous region?
[Unknown]: guangdong
What is the dual-letter country/region code for this unit?
[Unknown]: CN
CN = zhang biao, OU = aisaw, O = aisaw, L = shenzhen, ST = guangdong, C = CN is correct?
[No]: y
In this way, android. keystore is generated, and you do not need to create it again later. copy the file to the project path.
In this case, if the subscription succeeds, we can see that the binfile of the project contains webview_release.apk, which is an application that has been signed.
Note that if our project is dependent on other projects, we also need to create those projects ant environment, such as android applications will generally rely on android-support-v7-appcompat, at this time, we need to run the second step of the command on cd to this project, and we can see that there is a build. xml. Otherwise you may see the following error: build failed f: \ android \ adt-bundle-windows-x86-20140321 \ sdk \ tools \ ant \ build. xml: 471: Invalid
File: F: \ android \ adt-bundle-windows-x86-20140321 \ sdk \ extras \ android \ support \ v7 \ appcompat \ build. xml and other errors, This is intended in the appcompat Project No ant Environment
