This article Wheat College and small partners to share in detail about the android Ant command-line compilation and the APK signature details some of the implementation methods, this is a friend in the development of their own Android wrote, I hope to be helpful to everyone.

Recently in the development of Android, you need to refer to a third-party code into the project, under normal circumstances, directly under Eclipse to set the code to import the compiled output for the library, but a lot of code compiled under eclipse there will be a lot of inexplicable errors. Therefore, you can only compile the code using the command line method. Here's how:

1. Install the compiled Java, install android platform-tools, install ant, set up various environment variables. Some Linux under Ant has been integrated by default and needs to be installed by itself under Windows.

2. Use the Android tool to update the compilation configuration of your code.

3. Compile with the Ant tool to compile the debug version and release version.

4. Generate the private key for the code signing and sign the APK.

5. To align the apk file, the big file apk has a good effect.

The following is a reference to the bash code, which can be changed by itself, and when executed, sudo bash xxx.sh can be

The code is as follows

# Setup Java Home

Java_home = "/system/library/java/javavirtualmachines/1.6.0.jdk/contents/home"

# Setup Android Home

Android_home= "~/android-sdk-macosx"

# Setup Path

PATH = "$ANDROID _home/tools: $JAVA _home/bin: $PATH"

# Update Current Project

Android Update Project--path.

#android Update Project--path./LIBRARY/LIB1

#android Update Project--path./library/lib2

# Remove KeyStore

Rm-f Product.keystore

# Make Keystone

-keystore product.keystore-storepass password-keypass Password

-dname "Cn=product ou=android Team o=organization l=hongkong st=hongkong C=china"

# clean

Ant Clean

# Remove Ant.properties

Rm-f ant.properties

# Make Ant.properties

echo "Key.store=product.keystore" > Ant.properties

echo "Key.alias=product.keystore" >> ant.properties

# Build APK

Ant Release

# sign APK

# Jarsigner-verbose-keystore Product.keystore-signedjar

Description

Update your Android's ant compilation configuration, if the structure of your code changes, if your code contains referenced third-party library code, you need to update the code separately.

The code is as follows

# Update Current Project

Android Update Project--path.

#android Update Project--path./LIBRARY/LIB1

#android Update Project--path./library/lib2

Generate signature with KeyStore file, description of several parameters

-genkey Generating a secret key certificate

-alias aliases

Calculation algorithm of-KEYALG secret key

-validity Validity

-keystore KeyStore File path

-storepass secret key Vault Password

-keypass secret key Certificate password

-dname Issuer Information

cn= Issuer Name (individual name or product name)

ou= organizational unit name (team name)

o= Organization name (company name)

L= City/region

st= State/Province

C= Country Code

The code is as follows

# Make Keystone

Keytool-genkey-alias Product.keystore-keyalg rsa-validity 40000

-keystore product.keystore-storepass password-keypass Password

-www.maiziedu.com-keypass Password

-dname "Cn=product ou=android Team o=organization l=hongkong st=hongkong C=CN"

Build an ant auto-compiled ant.properties file, set Key.store and Key.alias two variables, and automatically sign and align the generated apk when ant release

The code is as follows

echo "Key.store=product.keystore" > Ant.properties

echo "Key.alias=product.keystore" >> ant.properties

Manual code signing, description of several parameters

-verbose Display Output

-keystore KeyStore Aliases

-signedjar signature apk file, the first parameter is the target file, the second is unsigned apk

The code is as follows

# sign APK

Jarsigner-verbose-keystore Product.keystore-signedjar bin/product_signed.apk bin/product-release-unsigned.apk Product.keystore

To align the apk manually

The code is as follows

# Zip Align apk

Zipalign-v 4 bin/product_signed.apk bin/product_final.apk
