ios和Android更新检测

一ios软件更新提示

1)服务器接口，

通常的做法是在自己的服务器上记录最新版本号，从iOS客户端请求，与本地版本号比较，不同则提示更新。这种做法简单，缺点是需要单独的服务器支持。

2)Appstore的接口？

不需要另外的服务器支持,方法最优

①

NSString *version = @"";

NSURL *url = [NSURL URLWithString:@"https://www.360docs.net/doc/e112676752.html,/lookup?id="];

versionRequest = [ASIFormDataRequest requestWithURL:url];

[versionRequest setRequestMethod:@"GET"];

[versionRequest setDelegate:self];

[versionRequest setTimeOutSeconds:150];

[versionRequest addRequestHeader:@"Content-Type" value:@"application/json"];

[versionRequest startSynchronous];

//Response string of our REST call

NSString* jsonResponseString = [versionRequest responseString];

NSDictionary *loginAuthenticationResponse = [jsonResponseString objectFromJSONString];

NSArray *configData = [loginAuthenticationResponse valueForKey:@"results"];

for (id config in configData)

{

version = [config valueForKey:@"version"];

}

//Check your version with the version in app store

if (![version isEqualToString:[itsUserDefaults objectForKey:@"version"]])

{

ProAlertView *createUserResponseAlert = [[ProAlertView alloc] initWithTitle:@"New Version!!" message: @"A new version of app is available to download" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles: @"Download", nil];

[createUserResponseAlert show];

[createUserResponseAlert release];

}

②

- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

// the user clicked one of the OK/Cancel buttons

if (buttonIndex == 1)

{

NSString *iTunesLink = @"itms-apps://https://www.360docs.net/doc/e112676752.html,/WebObjects/MZStore.woa/wa/viewSoftwareUpdate?id=&mt=8";

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];

}

}

二android版本升级提示

步骤：

1.检测当前版本的信息AndroidManifest.xml-->manifest-->android:versionName。

2.从服务器获取版本号（版本号存在于xml文件中）并与当前检测到的版本进行匹配，如果不匹配，提示用户进行升级，如果匹配则进入程序主界面。

3.当提示用户进行版本升级时，如果用户点击了确定，系统将自动从服务器上下载并进行自动升级，如果点击取消将进入程序主界面。

效果图：

1.获取当前程序的版本号

/*

* 获取当前程序的版本号

*/

private String getVersionName() throws Exception{

//获取packagemanager的实例

PackageManager packageManager = getPackageManager();

//getPackageName()是你当前类的包名，0代表是获取版本信息

PackageInfo packInfo = packageManager.getPackageInfo(getPackageName(), 0);

return packInfo.versionName;

}

2.获取服务器端的版本号

/*

* 用pull解析器解析服务器返回的xml文件 (xml封装了版本号)

*/

public static UpdataInfo getUpdataInfo(InputStream is) throws Exception{ XmlPullParser parser = Xml.newPullParser();

parser.setInput(is, "utf-8");//设置解析的数据源

int type = parser.getEventType();

UpdataInfo info = new UpdataInfo();//实体

while(type != XmlPullParser.END_DOCUMENT ){

switch (type) {

case XmlPullParser.START_TAG:

if("version".equals(parser.getName())){

info.setVersion(parser.nextText()); //获取版本号

}else if ("url".equals(parser.getName())){

info.setUrl(parser.nextText()); //获取要升级的APK文件

}else if ("description".equals(parser.getName())){

info.setDescription(parser.nextText()); //获取该文件的信息

}

break;

}

type = parser.next();

}

return info;

}

3.从服务器下载apk

public static File getFileFromServer(String path, ProgressDialog pd) throws Exception{ //如果相等的话表示当前的sdcard挂载在手机上并且是可用的

if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){ URL url = new URL(path);

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setConnectTimeout(5000);

//获取到文件的大小

pd.setMax(conn.getContentLength());

InputStream is = conn.getInputStream();

File file = new File(Environment.getExternalStorageDirectory(), "updata.apk");

FileOutputStream fos = new FileOutputStream(file);

BufferedInputStream bis = new BufferedInputStream(is);

byte[] buffer = new byte[1024];

int len ;

int total=0;

while((len =bis.read(buffer))!=-1){

fos.write(buffer, 0, len);

total+= len;

//获取当前下载量

pd.setProgress(total);

}

fos.close();

bis.close();

is.close();

return file;

}

else{

return null;

}

}

4.匹配、下载、自动安装

/*

* 从服务器获取xml解析并进行比对版本号

*/

public class CheckVersionTask implements Runnable{

public void run() {

try {

//从资源文件获取服务器地址

String path = getResources().getString(R.string.serverurl);

//包装成url的对象

URL url = new URL(path);

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setConnectTimeout(5000);

InputStream is =conn.getInputStream();

info = UpdataInfoParser.getUpdataInfo(is);

if(info.getVersion().equals(versionname)){

Log.i(TAG,"版本号相同无需升级");

LoginMain();

}else{

Log.i(TAG,"版本号不同 ,提示用户升级 ");

Message msg = new Message();

msg.what = UPDATA_CLIENT;

handler.sendMessage(msg);

}

} catch (Exception e) {

// 待处理

Message msg = new Message();

msg.what = GET_UNDATAINFO_ERROR;

handler.sendMessage(msg);

e.printStackTrace();

}

}

}

Handler handler = new Handler(){

@Override

public void handleMessage(Message msg) {

// TODO Auto-generated method stub

super.handleMessage(msg);

switch (msg.what) {

case UPDATA_CLIENT:

//对话框通知用户升级程序

showUpdataDialog();

break;

case GET_UNDATAINFO_ERROR:

//服务器超时

Toast.makeText(getApplicationContext(), "获取服务器更新信息失败", 1).show();

LoginMain();

break;

case DOWN_ERROR:

//下载apk失败

Toast.makeText(getApplicationContext(), "下载新版本失败", 1).show();

LoginMain();

break;

}

}

};

/*

*

* 弹出对话框通知用户更新程序

*

* 弹出对话框的步骤：

* 1.创建alertDialog的builder.

* 2.要给builder设置属性, 对话框的内容,样式,按钮

* 3.通过builder 创建一个对话框

* 4.对话框show()出来

*/

protected void showUpdataDialog() {

AlertDialog.Builder builer = new Builder(this) ;

builer.setTitle("版本升级");

builer.setMessage(info.getDescription());

//当点确定按钮时从服务器上下载新的apk 然后安装

builer.setPositiveButton("确定", new OnClickListener() {

public void onClick(DialogInterface dialog, int which) {

Log.i(TAG,"下载apk,更新");

downLoadApk();

}

});

//当点取消按钮时进行登录

builer.setNegativeButton("取消", new OnClickListener() {

public void onClick(DialogInterface dialog, int which) {

// TODO Auto-generated method stub

LoginMain();

}

});

AlertDialog dialog = builer.create();

dialog.show();

}

/*

* 从服务器中下载APK

*/

protected void downLoadApk() {

final ProgressDialog pd; //进度条对话框

pd = new ProgressDialog(this);

pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

pd.setMessage("正在下载更新");

pd.show();

new Thread(){

@Override

public void run() {

try {

File file = DownLoadManager.getFileFromServer(info.getUrl(), pd);

sleep(3000);

installApk(file);

pd.dismiss(); //结束掉进度条对话框

} catch (Exception e) {

Message msg = new Message();

msg.what = DOWN_ERROR;

handler.sendMessage(msg);

e.printStackTrace();

}

}}.start();

}

//安装apk

protected void installApk(File file) {

Intent intent = new Intent();

//执行动作

intent.setAction(Intent.ACTION_VIEW);

//执行的数据类型

intent.setDataAndType(Uri.fromFile(file),

"application/vnd.android.package-archive");

startActivity(intent);

}

/*

* 进入程序的主界面

*/

private void LoginMain(){

Intent intent = new Intent(this,MainActivity.class);

startActivity(intent);

//结束掉当前的activity

this.finish();

}

5.Updatainfo

public class UpdataInfo {

private String version;

private String url;

private String description;

public String getVersion() {

return version;

}

public void setVersion(String version) {

this.version = version;

}

public String getUrl() {

return url;

}

public void setUrl(String url) {

this.url = url;

}

public String getDescription() {

return description;

}

public void setDescription(String description) {

this.description = description;

}

}
