Android上架app版本检测更新app

1：请求接口返回如果有新版本则

/*** date:2020/9/22 0022* author:wsm (Administrator)* funcation:有市场打开。没有打开浏览器*/
public class AppUpdateUtils {public static void dialogUpdateVersion(Context context) {int index = 0;//获取应用市场的代码ArrayList<String> installedMarketPkgs = getInstalledMarketPkgs(context);for (int j = 0; j < installedMarketPkgs.size(); j++) {if (installedMarketPkgs.get(j).equals("com.tencent.android.qqdownloader") || installedMarketPkgs.get(j).equals("com.oppo.market") ||installedMarketPkgs.get(j).equals("com.xiaomi.market") || installedMarketPkgs.get(j).equals("com.bbk.appstore")) {Intent intent = new Intent("android.intent.action.VIEW", Uri.parse("market://details?id=这里是你的app应用的包名"));context.startActivity(intent);index = 1;break;}}if (index != 1) {Intent intent = new Intent();intent.setAction("android.intent.action.VIEW");
//            Uri download_url = Uri.parse(url);Uri download_url = Uri.parse("http://a.app.qq.com/o/simple.jsp?pkgname=这里是你的app应用的包名");intent.setData(download_url);context.startActivity(intent);}}/*** 获取当前手机上的应用商店数量** @param context* @return*/public static ArrayList<String> getInstalledMarketPkgs(Context context) {ArrayList<String> pkgs = new ArrayList<>();if (context == null)return pkgs;Intent intent = new Intent();intent.setAction("android.intent.action.VIEW");intent.addCategory(Intent.CATEGORY_DEFAULT);intent.setData(Uri.parse("market://details?id="));PackageManager pm = context.getPackageManager();// 通过queryIntentActivities获取ResolveInfo对象List<ResolveInfo> infos = pm.queryIntentActivities(intent,0);if (infos == null || infos.size() == 0)return pkgs;int size = infos.size();for (int i = 0; i < size; i++) {String pkgName = "";try {ActivityInfo activityInfo = infos.get(i).activityInfo;pkgName = activityInfo.packageName;} catch (Exception e) {e.printStackTrace();}if (!TextUtils.isEmpty(pkgName))pkgs.add(pkgName);}return pkgs;}}

2：判断是否有新版本，更新则调用跳转应用市场更新

 //立即更新AppUpdateUtils.dialogUpdateVersion(MainActivity.this);

另一种更新方式为app内部请求服务器地址apk更新
app内部服务器地址更新
