android 升级包检测并更新实现

android 升级包检测并更新实现
实现步骤：
1.获取当前android程序的包名或版本代码

public class Version {public int getCode() {              //android.content.ContextWrapper.getPackageManager()PackageManager packageManager = app.getPackageManager();int code = -1;try {code = packageManager.getPackageInfo(Package.name, 0).versionCode;}catch (PackageManager.NameNotFoundException e) {e.printStackTrace();}return code;}public String getName() {PackageManager packageManager = app.getPackageManager();String name = null;try {name = packageManager.getPackageInfo(Package.name, 0).versionName;}catch (PackageManager.NameNotFoundException e) {e.printStackTrace();}return name;}}

上面的版本代码是我们在AndroidManifest.xml配置的

<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.test.mobile" android:versionCode="100000100"android:versionName="1.0.1">

2.启动软件时从远程服务器端获取版本代码

versionName = app.server.getContent("/dist/version.txt").trim();

3.当前程序版本代码与远程获取的比对，不同则升级

if (currentVersionName.equals(versionName) || StrFuncs.isEmpty(versionName)) {return false;}

4.启动线程下载远程应用
a.获取android手机安装apk路径和相关权限

apkFilePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/temp/test_android.apk";apkFile = new File(apkFilePath);if (apkFile.exists()) {apkFile.delete();}

b.下载安装包apk

handler = new Handler();new Thread() {@Overridepublic void run() {app.server.download("/dist/test_android.apk", apkFilePath);handler.post(new Runnable() {public void run() {progressDlg.cancel();}});Intent intent = new Intent(Intent.ACTION_VIEW);intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");fromActivity.startActivity(intent);fromActivity.finish();}}.start();

在AndroidManifest.xml配置的权限

<uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
