Configure Gradle in Android studio to "generate the specified Versioncode from the command line prompt, Versionname, specify the package output path of the APK"

Demand:

1. Using Android Studio, build with Gradle

2. In actual development, we need to use Jenkins for packaging. We need to configure our Gradle script to support parameterization.

3. Want to obtain a configurable package script method, allow the configuration personnel to modify the server address as needed, versioncode, versionname, etc.

4. The configuration of the isolated source code, the user is configured in Jenkins.

Overview:

First show the parameters I 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

Parameter description:

2. The-P flag followed by the parameters, such as:

-pversion_code_para=101 means  passing in a Version_code_para parameter whose value is 101

The parameters here are all custom, I am here to participate in a number of parameters, there is versionname,versioncode, input file path, and the specified server address.


Realize:

Modify Versioncode and Versionname

In the above demo, we passed in the Gradle parameter, how to use it in Gradle? Here is the code I configured for Versioncode and Versionname, as shown in the following example:

 defaultconfig {minsdkversion  14 tar Getsdkversion  19 Signingconfig Signingconfigs.debug Buildconfigfield ("/ span> "String", "Api_host_user", "\" Http://10.0.1.232:9000\ "" ) Buildconfigfield ("/ span> "String", "Api_host_cabzoo", "\" http://10.0.1.232:9002\ "" ) Buildconfigfield ("/ span> "Boolean", "Is_check_version_update", "true" )  if  (Project.hasproperty (' Version_code_para '  if  (Project.hasproperty (' version_name_p ARA '  

All arguments passed through the command line or as properties of the project's built-in object determine whether the specified parameter name exists. How do I use parameters? You can use it directly, such as the following:
　　

Versioncode integer.parseint (Version_code_para)    note here, the transformation from string to int type

Use the same method as the normal variable. We also encounter the use of strings, which can be referenced using expressions, such as:
${parameter name}
Example:

FileName = Filename.replace (". apk", "-${android.defaultconfig.versionname}. apk")

By understanding the way variables (attributes, parameters) are read, we can encode them like normal code. Let's go back to our subject line. We need the Buildtypes node (Task)

Assemblebeta "Beta will call this our configured task, the demo code is as follows:

if (Project.hasproperty (' Api_host_user_para ') && project.hasproperty (' Api_host_cabzoo_para ')) {            beta {                true                signingconfig signingconfigs.debug                 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 ")            }        }

The name and storage path of the APK that controls the output

We continue to configure the directory of the APK output, which requires the configuration of the file name after compilation, how to get and set the input path? The code is as follows:

Android.applicationVariants.all {Variant    -----...    }}

I want to add the version name (versionname) to the output APK file name and write down the code:

if NULL {                = Filename.replace (". apk", "-${android.defaultconfig.versionname}.apk")            }

Adds the specified suffix to the APK file name you entered

if (Project.hasproperty (' Out_put_apk_suffix_para ')) {                = Filename.replace (". APK", "-${out_put_apk_ suffix_para}.apk ")            }

Increase the current date portion of the APK file name for the output

New Date (). Format (' yymmddhhmm ');             = Filename.replace (". apk", "-${today}.apk")

I also want to specify the APK storage directory:

if (Project.hasproperty (' Out_put_dir_para ')) {                = file ("${out_put_dir_para}");                 New File (Output_dir1, fileName)                " Output file Location: "+ output.outputfile                //}            

The sample code for this section is as follows:

Android.applicationVariants.all {variant-Variant.outputs.each {Output-def OutputFile=Output.outputfileif(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=NewDate (). Format (' YYMMDDHHMM '); FileName= Filename.replace (". apk", "-${today}.apk")            if(Project.hasproperty (' Out_put_dir_para ') ) {File Output_dir1= File ("${out_put_dir_para}"); Output.outputfile=NewFile (Output_dir1, fileName) println"Output File location:" +Output.outputfile//}}Else{output.outputfile=NewFile (outputfile.parent, fileName) println"Output File location:" +output.outputfile} }}}

My entire Gradle script, the Build.gradle file is as follows:
