相信很多项目都有这样的需求，给请求头添加用户当前应用版本的信息，直接上代码如下：
一，获取当前应用版本名 （versionName）
/**
*得到版本名manifest.vml version Name
*@paramcontext
*@return
*/
public static String getVersion(Context context){
String versionName ="";
try{
PackageManager packageManager = context.getPackageManager();
//得包名
String packageName = context.getPackageName();
//包的信息，一个包有多少个activity,
PackageInfo packageInfo = packageManager.getPackageInfo(packageName,0);
versionName = packageInfo.versionName;
}catch(PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return versionName;
}
二、获取当前App版本号
/**
*获取本地apk版本号
*@return
*/
public static int getVerCode(Context context) {
intverCode =0;
try{
PackageManager packageManager = context.getPackageManager();
//得包名
String packageName = context.getPackageName();
//包的信息，一个包有多少个activity,
PackageInfo packageInfo = packageManager.getPackageInfo(packageName,0);
verCode = packageInfo.versionCode;
L.e(verCode+"code");
}catch(PackageManager.NameNotFoundException e) {
L.e(e.getMessage());
}
return verCode;
}
三、我们将获取版本信息封装成工具类 VersionUtil
public class versionUtil {
/**
*得到版本名manifest.vml version Name
*@paramcontext
*@return
*/
public static String getVersion(Context context){
String versionName ="";
try{
PackageManager packageManager = context.getPackageManager();
//得包名
String packageName = context.getPackageName();
PackageInfo packageInfo = packageManager.getPackageInfo(packageName,0);
versionName = packageInfo.versionName;
}catch(PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return versionName;
}
/**
*获取本地apk版本号
*@return
*/
public static int getVerCode(Context context) {
intverCode =0;
try{
PackageManager packageManager = context.getPackageManager();
String packageName = context.getPackageName();
PackageInfo packageInfo = packageManager.getPackageInfo(packageName,0);
verCode = packageInfo.versionCode;
L.e(verCode+"code");
}catch(PackageManager.NameNotFoundException e) {
L.e(e.getMessage());
}
return verCode;
}
}
请求头添加应用版本信息用法：
Request request = new Request.Builder().addHeader("App-Version",versionUtil.getVerCode(getApplicationContext()).build();
