Android ant command Line compilation and APK signature detailed

Recently, when doing Android development, you need to refer to a third party code into the project, in general, directly under Eclipse to set the code to be imported to the library can be compiled, but a lot of code in eclipse to compile a lot of inexplicable errors. Therefore, you can only compile the code using command-line methods. The specific methods are as follows:

1. Install Java for compilation, install Android Platform-tools, install ant, set up all kinds of environment variables. Some Linux has been integrated by default, and Windows needs to be installed on its own.
2. Use the Android tool to update the compiled configuration of your code.
3. Using the Ant tool for compiling, you can compile the debug and release versions.
4. Generate the private key for code signing and sign the APK.
5. apk file alignment, for large file apk has a good effect.

Here's a reference to the bash code that you need to change, when executed, sudo bash xxx.sh can

The code is as follows

Copy Code

# 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 Keytool-genkey-alias Product.keystore-keyalg rsa-validity 40000 -keystore product.keystore-storepass password-keypass Password -dname "Cn=product ou=android team o=organization l=hongkong St=hongkong" # 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 # bin/product_signed.apk bin/product-release-unsigned.apk Product.keystore # Zip Align apk # zipalign-v 4 bin/product_signed.apk bin/product_final.apk

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

The code is as follows	Copy Code
# Update Current Project Android Update Project--path. #android Update Project--path./LIBRARY/LIB1 #android Update Project--path./library/lib2

KeyStore file for signature generation, description of several parameters
-genkey Generate secret Key certificate
-alias Alias
Computational algorithm of-KEYALG secret key
-validity Validity Period
-keystore secret key Library file path
-storepass secret key Library password
-keypass secret key Certificate password
-dname publisher Information
cn= Publisher name (personal 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	Copy Code
# Make Keystone Keytool-genkey-alias Product.keystore-keyalg rsa-validity 40000 -keystore product.keystore-storepass password-keypass Password -dname "Cn=product ou=android team o=organization l=hongkong St=hongkong"

Generate the Ant.properties file for Ant automatic compilation, set Key.store and Key.alias two variables, and automatically sign and align the generated apk when ant release

The code is as follows	Copy Code
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 Alias
-signedjar signature apk file, the first parameter is the target file, the second is unsigned apk

The code is as follows	Copy Code
# Sign APK Jarsigner-verbose-keystore Product.keystore-signedjar bin/product_signed.apk bin/product-release-unsigned.apk Product.keystore

To align apk manually

code is as follows	copy code
# Zip Align APK Zipalign-v 4 bin/product_signed.apk bin/product_final.apk
