Requirements:
1. Build with Android Studio and Gradle 2. In actual development, we need to use Jenkins for packaging. We need to configure our Gradle scripts to support parameterization. 3. Want to get a configurable package script method that allows the configuration personnel to change the server address, versionCode, versionName, etc. 4. Isolated source code configuration, user configuration in Jenkins.
Summary:
Show me the parameters I have configured, which can be executed at the command prompt, as follows:
Gradle assembleBeta - PVERSION_CODE_PARA = 101 - PVERSION_NAME_PARA = fd21.0 - POUT_PUT_DIR_PARA = / Users/zhangyunfei/Desktop/yyy - PAPI_HOST_USER_PARA = http://10.0.1.245:9000 - PAPI_HOST_CABZOO_PARA = http://10.0.1.245:9002 - POUT_PUT_APK_SUFFIX_PARA = 245 AssembleBeta, where Beta is my configured build task, 2. -P indicates that the following content is the parameter, such as: -PVERSION_CODE_PARA=101 Indicates that a VERSION_CODE_PARA parameter is passed with a value of 101Copy the codeThe parameters here are all custom, I entered multiple parameters here, including versionName,versionCode, input file path, and the specified server address.
Implementation:
Change the versionCode and versionName
In this example, we passed in gradle parameters. How do we use them in Gradle? Here is my code for configuring versionCode and versionName as shown in the following example:
defaultConfig { minSdkVersion 14 targetSdkVersion 19 signingConfig signingConfigs.debug buildConfigField("String", "API_HOST_USER", "\" http://10.0.1.232:9000\ "") buildConfigField (" String", "API_HOST_CABZOO", "\" http://10.0.1.232:9002\ "") buildConfigField (" Boolean", "IS_CHECK_VERSION_UPDATE", "true") if (project.hasProperty('VERSION_CODE_PARA')) { versionCode Integer.parseInt(VERSION_CODE_PARA) } if (project.hasProperty('VERSION_NAME_PARA')) { versionName VERSION_NAME_PARA } }Copy the codeWe need to configure the defaultConfig node to read the value of the parameter passed above as versionCode or versionName. When reading a parameter, we first check if the parameter exists, using this code:
Project.hasproperty (' parameter name ')Copy the codeAll arguments passed through the command line are either properties of the project built-in object, and we check whether the specified parameter name exists. How do you use parameters? Use it directly, for example:
VersionCode Integer.parseInt(VERSION_CODE_PARA) Notice that a transformation has been made from a string to an int versionName VERSION_NAME_PARACopy the codeIt’s the same as normal variables. We will also encounter situations where we can use expressions to refer to strings, such as:
${parameter name}Copy the codeExample:
fileName = fileName.replace(".apk", "-${android.defaultConfig.versionName}.apk")
Copy the codeKnowing how variables (attributes, parameters) are read, we can code like normal code. Let’s go back to our subject line. We need to add a custom packaging under the buildTypes node (task), such as a configuration named beta. Beta is my custom. We saw the use of this parameter at the beginning. The beta in “gradle assembleBeta” will call the task we have configured.
if (project.hasProperty('API_HOST_USER_PARA') && project.hasProperty('API_HOST_CABZOO_PARA')) {
beta {
debuggable true
signingConfig signingConfigs.debug
minifyEnabled false
buildConfigField("String", "API_HOST_USER", "\"" + API_HOST_USER_PARA + "\"")
buildConfigField("String", "API_HOST_CABZOO", "\"" + API_HOST_CABZOO_PARA + "\"")
buildConfigField("Boolean", "IS_CHECK_VERSION_UPDATE", "false")
}
}
Copy the codeControls the name and location of the APK output
We continue to configure the apK output directory configuration, this needs to obtain the compiled file name configuration, how to obtain and set the input path? The code is as follows:
android.applicationVariants.all { variant -> variant.outputs.each { output ->{ ....... }}Copy the codeI want to add the versionName to the output APK file name, writing the code:
if (android.defaultConfig.versionName ! = null) { fileName = fileName.replace(".apk", "-${android.defaultConfig.versionName}.apk") }Copy the codeAdds the specified suffix to the entered APK file name
if (project.hasProperty('OUT_PUT_APK_SUFFIX_PARA')) {
fileName = fileName.replace(".apk", "-${OUT_PUT_APK_SUFFIX_PARA}.apk")
}
Copy the codeAdds the current date part to the output APK file name
def today = new Date().format('yyMMddHHmm');
fileName = fileName.replace(".apk", "-${today}.apk")
Copy the codeI also want to specify the directory where APK is stored:
if (project.hasProperty('OUT_PUT_DIR_PARA')) { File output_dir1 = file("${OUT_PUT_DIR_PARA}"); OutputFile = new File(output_dir1, fileName) println "outputFile location:" + output.outputFile //}}Copy the codeExample code for this section is as follows:
android.applicationVariants.all { variant -> variant.outputs.each { output -> def outputFile = output.outputFile if (outputFile ! = null && outputFile.name.endsWith('.apk')) { def fileName = outputFile.name; if (android.defaultConfig.versionName ! = null) { fileName = fileName.replace(".apk", "-${android.defaultConfig.versionName}.apk") } if (project.hasProperty('OUT_PUT_APK_SUFFIX_PARA')) { fileName = fileName.replace(".apk", "-${OUT_PUT_APK_SUFFIX_PARA}.apk") } def today = new Date().format('yyMMddHHmm'); fileName = fileName.replace(".apk", "-${today}.apk") if (project.hasProperty('OUT_PUT_DIR_PARA')) { File output_dir1 = file("${OUT_PUT_DIR_PARA}"); OutputFile = new File(output_dir1, fileName) println" "+ output.outputFile //}} else {output.outputFile = new File(outputFile. Parent, fileName) println" " + output.outputFile } } }Copy the code}
My entire Gradle script,build.gradle file is as follows: apply plugin: ‘Android’
