Signing in Release Mode
When your application is ready for release to other users, you must:
- Obtain a suitable private key
- Compile the application in release mode
- Sign your application with your private key
- Align the final APK package
发布release版本要有4步
官方说明： http://developer.android.com/tools/publishing/app-signing.html#releasecompile 平时通过Eclipse生成在bin目录下的apk文件，都是debug版的，如何创建release版的软件呢？ 其实还是挺简单的。 1. 通过java自带的keytool工具，创建release版的keystore keytool -genkey -v -keystore keystore_name.keystore -alias alias_name -keyalg RSA -validity 10000
keystore_name.keystore：要创建的release版keystore的文件名 alias_name：别名？取个好记点的名字吧，后面还要用到的 （填写配置文件)-keyalg RSA：通过RSA算法生成 -validity 10000：有效期，单位是天 如果java环境配置正常，输入命令后会出现下列信息 Enter keystore password:（keystore的密码） Re-enter new password:（确认keystore的密码） What is your first and last name? [Unknown]: （姓名，用自己喜欢的名字吧，不知道会显示在哪里） What is the name of your organizational unit? [Unknown]: （组织单位） What is the name of your organization? [Unknown]: （组织，不知道和上面那个有什么区别） What is the name of your City or Locality? [Unknown]: （城市） What is the name of your State or Province? [Unknown]: （州，省，县） What is the two-letter country code for this unit? [Unknown]: CN Is CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=CN correct? [no]: yes （确认输入的信息） Generating 1,024 bit RSA key pair and self-signed certificate (SHA1withRSA) with a validity of 10,000 days for: CN=Unknown, OU=Unknown, O=Unknown, L=Unknown, ST=Unknown, C=CN Enter key password for <alias_name> (RETURN if same as keystore password):（alias的密码，如果和keytore密码一致，直接回车） Re-enter new password:（确认alias的密码） [Storing my-release-key.keystore]
2.发布Release版本
Signing in Release Mode
When your application is ready for release to other users, you must:
- Obtain a suitable private key
- Compile the application in release mode
- Sign your application with your private key
- Align the final APK package
官方的步骤有4步，编译release版本的应用程序
2.1 Eclipse导出在Eclipse中，右键要发布的项目，依次选择Android Tool -> Export Signed Application Package... 然后就是step-by-step了，选择刚才生成的release版keystore，输入密码，选择alias，输入alias密码，生成release版的apk。
2.2 采用ANT命令行形式$ ant release
By default, the build script compiles the application APK without signing it. The output file in your project bin/ will be <your_project_name>-unsigned.apk. Because the application APK is still unsigned, you must manually sign it with your private key and then align it using zipalign. 默认编译出来的版本是没有证书的
<your_project_name>-unsigned.apk ，需要手动添加证书和对齐
To specify your keystore and alias, open the project ant.properties file (found in the root of the project directory) and add entries for key.store and key.alias. For example: 我们可以在
ant.properties文件中指定证书位置和对齐
# This file is used to override default values used by the Ant build system.
#
# This file must be checked into Version Control Systems, as it is
# integral to the build system of your project.
# This file is only used by the Ant script.
# You can use this to override default values such as
# 'source.dir' for the location of your java source folder and
# 'out.dir' for the location of your output folder.
# You can also use it define how the release builds are signed by declaring
# the following properties:
# 'key.store' for the location of your keystore and
# 'key.alias' for the name of the key to use.
# The password will be asked during the build when you use the 'release' target.
#我的证书在上一级目录下
#alias是创建证书时填写的alias_name
key.store=../keystore_name.keystore
key.alias=alias_name
接下来的步骤很easy了
Save your changes. Now you can build a signed .apk in release mode:
- Open a command-line and navigate to the root of your project directory.
- Use Ant to compile your project in release mode:
ant release
- When prompted, enter you keystore and alias passwords.
Caution: As described above, your password will be visible on the screen.
This creates your Android application .apk file inside the project bin/ directory, named<your_project_name>-release.apk. This .apk file has been signed with the private key specified inant.properties and aligned with zipalign. It's ready for installation and distribution.
ant release后会生成一个
<your_project_name>-release.apk的版本
啊，世界清静了~~~ 最后就是安装了。 由于使用了新的签名，必须先卸载原来安装的程序才可以安装。 /////////////////////////////////////////////////////////////////////////////////////////////////////////////
常见问题：
生成的debug和release有什么区别 大小差不多
Support for a true debug build. Developers no longer need to add the android:debuggable attribute to the tag in the manifest — the build tools add the attribute automatically. In Eclipse/ADT, all incremental builds are assumed to be debug builds, so the tools insert android:debuggable="true". When exporting a signed release build, the tools do not add the attribute. In Ant, a ant debug command automatically inserts the android:debuggable="true" attribute, while ant release does not. If android:debuggable="true" is manually set, then ant release will actually do a debug build, rather than a release build.
