I've exported an apk from eclipse. I am able to install it without any problem if I copy it to the phone's sd card.
When trying to download via phone's (Galaxy S) browser I get: "Download unsuccessful".
I have set mime type application/vnd.android.package-archive in the mime.types, restarted apache, still same result. Also tried :
<a href="downloads/my_apk.apk" type="application/vnd.android.package-archive">Download App</a>
Still no luck.
I am able to download and install applications from android market. I suspect that apache is not sending the mime type but this is just a shot in the dark. How can I fix the problem and be able to install APKs from my web server? (or at least to check if apache sends correct header with mime type)
Any help will be appreciated.

It is better if you add the .apk extension to the apache`s mime config. Take a look at this example:https://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
You can just find the "apk" record and copy the row to the file /etc/mime.types at your server: application/vnd.android.package-archive apk Also add this to /etc/apache2/mods-available/mime.conf : AddType application/vnd.android.package-archive .apk (There are some other AddType-s, put it after them for sure). From here on you don't have to put anything for the apk`s mime-type in the tag, the server will handle this. ;) UPDATE: fixed a bug in AddType line

After all I found the problem thanks in part to CommonsWare advise.
Directory where I put apks for downloads is protected by simpe auth. Phone's browser correctly asks (once) for username/password when browsing it but obviously forgets to send auth info when trying to download the file and that causes 401 Unauthorized. Solution: remove basic auth from that dir or use another unprotected dir for the apks.

Use
curl to test the Web server to make sure it is responding to the HTTP request and returning the proper MIME type. Also, example your server logs to see what error is being logged. |

안드로이드는 안드로이드 마켓분 아니라 여러 가지 경로로 어플리케이션을 설치할 수 있도록 지원합니다. 안드로이드 마켓 다음으로 쉽게 배포할 수 있는 방법으로 웹서버를 통한 배포방법이 있습니다. 웹서버 배포를 위해서는 웹서버의 Mime-Type만 설정해주고 파일을 업로드해두면 됩니다.
apk를 application/vnd.android.package-archive로 설정하면 됩니다.
CentOS, Fedora등 RedHat 계열의 리눅스에서는 /etc/mime.types 파일을 편집한후
application/vnd.android.package-archive apk
위 라인을 추가하고 apache를 재가동하면 적용됩니다.

이번 글에서는, 다음과 같은 과정을 기술한다.
1. apk 파일을 다운 받을 수 있는 WAS 구축(HTML의 a 태그를 이용한다.)
2. 안드로이드 웹뷰를 통한 웹페이지 접근
3. 웹뷰 클라이언트를 오버라이딩하여 apk 파일을 sd 카드 내에 다운 받기
4. 다운 받은 apk를 안드로이드 패키지 매니저를 통해 install 하기
1. apk 파일을 다운 받을 WAS 구축
WAS는 톰캣을 이용했다. 톰캣의 설치는 간단하므로 이 글에서는 제외한다. 참고로 난 우분투에서 만들었다. war을 톰캣 서버에 deploy할 때 다음과 같은 html을 추가했다.
- war 파일 내 경로 : test/
- 경로 내 포함된 파일 : test.html, HelloWorld.apk
1.1 test.html
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h2>
<a href="http:// ip 주소 :8180/rfidtest/test/HelloWorld.apk">click here to download apk file. </a>
</h2>
</body>
</html>
위의 소스를 보면 알겠지만, <a> 태그를 통해 apk 파일을 다운할 수 있도록 했다.
1.2. HelloWorld.apk : 다운로드될 apk 파일. TextView를 통해 HelloWorld 텍스트를 뿌리는 기본 app이다.
2. 안드로이드 웹뷰를 통한 웹페이지 접근
webView.loadUrl("http:// ip 주소/rfidtest/test/test.html"); // 웹뷰를 통해 웹페이지를 접근한다.
webView.getSettings().setJavaScriptEnabled(true); // 자바 스크립트를 enable한다. (이번 글 내용과는 상관 없다.)
webView.requestFocus(); // 웹뷰가 포커스를 가진다.(클릭 및 터치를 app 내에서 처리해야하므로 필요하다.
webView.setWebViewClient(new Callback()); // 웹뷰 클라이언트 등록( 3에서 자세히 설명)
3. 웹뷰 클라이언트를 오버라이딩하여 apk 파일을 sd 카드 내에 다운 받기
4. 다운 받은 apk를 안드로이드 패키지 매니저를 통해 install 하기
웹뷰를 통해 보여지는 페이지에서, <a> 태그로 이루어진 부분을 클릭(혹은 터치)하게 될 때 그 처리를 담당하는 곳이 shouldOverrideUrlLoading() 메서드이다. 코드는 다음과 같다.
private class Callback extends WebViewClient {
private void downloadFile(String fileUrl){
URL myFileUrl =null;
try {
myFileUrl= new URL(fileUrl);
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
HttpURLConnection conn= (HttpURLConnection)myFileUrl.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
// 다운 받는 파일의 경로는 sdcard/ 아래 이다. 단, sdcard에 접근하려면 uses-permission에 android.permission.WRITE_EXTERNAL_STORAGE을 추가해야한다.
String mPath = "sdcard/HelloWorld.apk";
FileOutputStream fos;
File f = new File(mPath);
if ( f.createNewFile() ) {
fos = new FileOutputStream(mPath);
int read;
while ( (read = is.read()) != -1) {
fos.write(read);
}
fos.close();
}
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(getApplicationContext(), "download complete", 0).show();
// 안드로이드 패키지 매니저를 통해 다운 받은 apk 파일을 처리하도록 한다.
File apkFile = new File(Environment.getExternalStorageDirectory()+ "/HelloWorld.apk");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType( Uri.fromFile(apkFile), "application/vnd.android.package-archive");
startActivity(intent);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, final String urlStr) {
// <a> 태그의 href 속성 값이 urlStr로 전달되므로, 파일을 다운로드 하면 된다.
downloadFile(urlStr);
return super.shouldOverrideUrlLoading(view, urlStr);
}
}

cocos2d-x 로 만든 다음에 안드로이드 apk 를 만들고 그동안 설치 하는건 문제가 없었는데요.
웹페이지를 통해서 apk를 다운 받고 다운로드상태창(?)에서 다운이 완료된 뒤 설치하려고 하면 실패하네요.
알림에 다운로드가 완료되었다고 나와서 설치하려고 클릭하면 "파일을 열 수 없습니다." 라고 나옵니다.
그러고 난 다음에 알림에서 사라집니다.
파일이 잘못된건가 싶어서 내파일에서 다운로드 폴더로 들어가서 설치하면 문제없이 설치가 됩니다.
웹에서 다운받을때 바로 설치하기 위한 옵션 같은게 있나요?
정확히 말하면 파일을 받고 나서 알림 화면에서 설치하기 위한 방법이요..
안드로이드나 앱은 초보라서 어떤 부분을 설명해야 할지도 잘 모르겠네요..

To download a file without the browser do sth. like this:
String apkurl = "http://your.url.apk"; InputStream is; try { URL url = new URL(apkurl); HttpURLConnection con = (HttpURLConnection) url.openConnection(); con.setRequestMethod("GET"); con.setDoOutput(true); con.connect(); is = con.getInputStream(); } catch (SSLException e) { // HTTPS can end in SSLException "Not trusted server certificate" } // Path and File where to download the APK String path = Environment.getExternalStorageDirectory() + "/download/"; String fileName = apkurl.substring(apkurl.lastIndexOf('/') + 1); File dir = new File(path); dir.mkdirs(); // creates the download directory if not exist File outputFile = new File(dir, fileName); FileOutputStream fos = new FileOutputStream(outputFile); // Save file from URL to download directory on external storage byte[] buffer = new byte[1024]; int len = 0; while ((len = is.read(buffer)) != -1) { fos.write(buffer, 0, len); } fos.close(); is.close(); // finally, install the downloaded file install(path + fileName);

Due to Android security model it is not possible to install Apk file automatically.

You can temp. download it to an sd card, install it with the package manager and then remove it again.
protected void install(String fileName) { Intent install = new Intent(Intent.ACTION_VIEW); install.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive"); startActivity(install); }

why not trying with a download manage and a broadcast receiver that would intercept when download is finished? Download manager works for ANDROID 2.3+ though
Example here: myWebView.setWebViewClient(new WebViewClient() { @Override public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { Log.d("WEB_VIEW_TEST", "error code:" + errorCode + " - " + description); } @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { // handle different requests for different type of files // this example handles downloads requests for .apk and .mp3 files // everything else the webview can handle normally if (url.endsWith(".apk")) { Uri source = Uri.parse(url); // Make a new request pointing to the .apk url DownloadManager.Request request = new DownloadManager.Request(source); // appears the same in Notification bar while downloading request.setDescription("Description for the DownloadManager Bar"); request.setTitle("YourApp.apk"); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { request.allowScanningByMediaScanner(); request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); } // save the file in the "Downloads" folder of SDCARD request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "SmartPigs.apk"); // get download service and enqueue file DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE); manager.enqueue(request); } else if(url.endsWith(".mp3")) { // if the link points to an .mp3 resource do something else } // if there is a link to anything else than .apk or .mp3 load the URL in the webview else view.loadUrl(url); return true; } }); Full answer here: user bboydflo Downloading a file to Android WebView (without the download event or HTTPClient in the code) Broadcast receiver to intercept when download has finished private BroadcastReceiver onDownloadComplete = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) { // toast here - download complete } } }; remember to recister recevier in the main activity like this: registerReceiver(onDownloadComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

Android DownloadManager Example
The Android DownloadManager introduced in Android 2.3. (API 9) is a system service which allows to handle long-running HTTP downloads in the background and notify the triggering application via a broadcast receiver once the download is finished.
Here is a little example for using the DownloadManager. The project will be called “de.vogella.android.downloadmanager” with the activity “DownloadManagerActivity” based on Android API9 or higher.
Change “main.xml” to the following.

Also add the permission to go to the internet to your app.
If you implemented this example you have an Android application which can download my picture (sorry for this ;-)) and allow you to switch to the download manager to see the finished downloads.
Hope this helps.
You find me also on Twitter.

DownloadManager
extends Object
| java.lang.Object | |
| ↳ | android.app.DownloadManager |
Class Overview
The download manager is a system service that handles long-running HTTP downloads. Clients may request that a URI be downloaded to a particular destination file. The download manager will conduct the download in the background, taking care of HTTP interactions and retrying downloads after failures or across connectivity changes and system reboots. Instances of this class should be obtained through getSystemService(String) by passing DOWNLOAD_SERVICE. Apps that request downloads through this API should register a broadcast receiver for ACTION_NOTIFICATION_CLICKED to appropriately handle when the user clicks on a running download in a notification or from the downloads UI. Note that the application must have the INTERNET permission to use this class.

I have a webview in my Android Application. When user goes to webview and click a link to download a file nothing happens.
URL = "my url"; mWebView = (WebView) findViewById(R.id.webview); mWebView.setWebViewClient(new HelloWebViewClient()); mWebView.getSettings().setDefaultZoom(ZoomDensity.FAR); mWebView.loadUrl(URL); Log.v("TheURL", URL); How to enable download inside a webview?? If I disable webview and enable the intent to load the url on broswer from application then download works seamlessly. String url = "my url"; Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(url)); startActivity(i); Can someone help me out here. The page loads without issue but the link to a image file in the html page is not working.... Thanks in advance for your time.

Have you tried?
mWebView.setDownloadListener(new DownloadListener() { public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) { Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(url)); startActivity(i); } });

I am currently building an Android app using HTML5. Inside my app, I am providing link to a HTML file available inside tomcat server on my machine.
<div><a href="http://localhost:8082/directDownload/sample.html">Beep</a></div> The HTML file "sample.html" has link to download a file in same file location, where the sample.html is placed. sample.html has this --> <a href="MyFirstOnMosync.apk">Click to download</a>The problem here is, when I run my app on an android mobile, the link stays dumb and it won't initiate the download from the given path. But, the same URL when I open in a web browser, the download starts. Could anyone let me know why this URL is not initiating the download inside my app?? I already enabled "Allow installation of non-Market applications" in the settings of my android device.

If you are using real device you must set your url with static ip of your machine like
192.168.0.10 and in emulator 10.0.0.2See this post.

Use 10.0.2.2 as IP for server running on the same machine as the Android emulator.
Check out following post with similar problem: Download File inside WebView Check out this link for setting up the mime type in tomcat. Copied for reference: In Tomcat 5.x and 4.x, the default mappings between MIME types and file extensions are stored in the file tomcat_home/conf/web.xml, where tomcat_home is the path under which Tomcat was installed on your server. The mappings specified there are applied to all web / WAP applications hosted on your Tomcat server. Application-specific mappings should be set in the WEB-INF/web.xml file under the directory of your web / WAP application. Each mapping is specified with the <mime-mapping>, <extension> and <mime-type> tags. Here is an example:<web-app> ... <mime-mapping> <extension>xhtml</extension> <mime-type>application/vnd.wap.xhtml+xml</mime-type> </mime-mapping> <mime-mapping> <extension>wml</extension> <mime-type>text/vnd.wap.wml</mime-type> </mime-mapping> <mime-mapping> <extension>wmls</extension> <mime-type>text/vnd.wap.wmlscript</mime-type> </mime-mapping> <mime-mapping> <extension>wbmp</extension> <mime-type>image/vnd.wap.wbmp</mime-type> </mime-mapping> ... </web-app>

안드로이드 프로그램에서 자기 자신이나 다른 어플의 apk를 설치시켜야 하는 경우가 존재할 수 있습니다. 이러한 경우 아래 코드를 사용하면 apk 를 설치할 수 있습니다.
File apkFile = new File(“/sdcard/ApkTest.apk”);
Uri apkUri = Uri.fromFile(apkFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType( Uri.fromFile(apkFile), “application/vnd.android.package-archive”);
startActivity(intent);
Uri apkUri = Uri.fromFile(apkFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType( Uri.fromFile(apkFile), “application/vnd.android.package-archive”);
startActivity(intent);
안드로이드에서 브라우저로 다운받은 apk 파일을 선택하여 설치하는 경우에도 위 코드와 동일한 방법으로 설치가 되는 것으로 파악하고 있습니다. 참고로 시스템 퍼미션으로 구동되는 시스템 애플리케이션에서는 다른 방법으로도 설치가 가능하다고 합니다.
또한 apk를 명령어로 설치, 삭제를 할 수 있는데 방법은 다음과 같습니다.
설치 : adb install apkfilename
삭제 : adb uninstall pakeagename
재설치 : adb install -r apkfilename
삭제 : adb uninstall pakeagename
재설치 : adb install -r apkfilename
adb는 sdk안에 tools 폴더에 있습니다. 그러므로 sdk를 다운로드 받아서 사용하셔야 합니다. 환경변수로 폴더를 설정해 두면 어디서나 위 명령어를 사용할 수 있으니 편하게 개발을 할 수 있습니다.
한가지 더 방법으로는 apk 파일이 인터넷에 올려져있다면 안드로이드 폰에 있는 인터넷 브라우저로 해당 url에서 파일을 다운로드 받아서 설치를 하는 것입니다. 다운로드 받은 파일을 클릭하게 되면 설치가 진행 될 것입니다.

I'm looking for a sample web page (html code) with a link that will install an apk file directly on my phone by clicking on the link.

Just link to the apk file in the HTML. It couldn't be any simpler.
<a href="path to my .apk file">link</a> You will have to have "install apps from unknown sources" enabled on your phone.

If you're using ASP.NET, then you'll need to insert the following in your web.config file:
<configuration> ... <system.webServer> <staticContent> <mimeMap fileExtension=".apk" mimeType="application/vnd.android.package-archive" /> </staticContent> </system.webServer> ... </configuration> Apart from that (as others have said), you just need a normal link: <a href="myAndroidApp.apk">Click here</a> and tell your users to enable the Security -> Unknown sources option in Settings.

In .Net this is what I did, I created an
.asmx page then a QR code that pointed to it other wise I kept getting a 404, then this on page load.protected void Page_Load(object sender, EventArgs e){ ViewState["PreviousPage"] = Request.UrlReferrer; string filepath = Server.MapPath("AcsMainMenu.apk"); FileInfo droidfile = new FileInfo(filepath); if (droidfile.Exists) { Response.ClearContent(); Response.AddHeader("Content-Disposition", "attachment; filename=" + droidfile.Name); Response.AddHeader("Content-Length", droidfile.Length.ToString()); Response.ContentType = "application/vnd.android.package-archive"; Response.TransmitFile(droidfile.FullName); Response.Flush(); Response.End(); Response.Redirect(ViewState["PreviousPage"].ToString()); } }

Interesting. I do wonder why it looks like there’s no UploadManager, feels like missing the “Yang” in “Yin and Yang”.
@Casper: Upload depends highly on the receiving side.
@Lars: POST payload vs. GET body and just some slightly different HTTP codes. I’d like if I could just invoke an upload service (picture upload to Flickr, Dropbox sync etc.) without having to handle this is my own heavyweight custom background service.
This code help me solve my download problem. Thank a lot!
Is there any class that i can use for earlier versions of android?
@Muneeb AFAIK you have to use HttpClient directly. For example in a Thread..
