相信很多項目都有這樣的需求，給請求頭添加用戶當前應用版本的信息，直接上代碼如下：
一，獲取當前應用版本名 （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，一個包有多少個activity,
PackageInfo packageInfo = packageManager.getPackageInfo(packageName,0);
versionName = packageInfo.versionName;
}catch(PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return versionName;
}
二、獲取當前App版本號
/**
*獲取本地apk版本號
*@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，一個包有多少個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、我們將獲取版本信息封裝成工具類 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;
}
/**
*獲取本地apk版本號
*@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;
}
}
請求頭添加應用版本信息用法：
Request request? = new Request.Builder().addHeader("App-Version",versionUtil.getVerCode(getApplicationContext()).build();
