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>Beep</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 --> Click to download
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 10.0.0.2
See 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>

I have a Xamarin app and localhost API. I'm trying to connect to the API from the app, but it could not be found. I edited my applicationhost.config file and I tried localhost, 10.0.2.2 and my IP address in the call, but it was not working.
So, how do I configure simple API access? (The API itself is working well)
There is simple workaround to connect Emulator & Simulator to localhost API.
Download third party software NgRok for Windows at any specific location of your PC. It just contains one executable file called ngrok.exe (you not need to install it).
Now execute your service on your preferred browser. Than follow below steps.
Open your ngrok.exe file path in command prompt
Keep your service url (take from your browser) with prefix ngrok http --host-header=rewrite and hit enter.
Now go to your browser where you have executed your service open new tab and type localhost:4040 than press enter -->Go to status there you will find your public url which you can use in your mobile application.
Note: Url structure should be like this public const string BaseUri = "https://8c56892f.ngrok.io/"; followed by / in last. Try not to append unnecessary /.
Benifits
You can debug services from one Visual Studio to another.
Your url will be active until you close command prompt.
In browser or command prompt track your requests status like Ok, Not found etc.

Hope it help you.
That 10.0.2.2 address is used for the Google emulators. For the Microsoft emulator you want to use 169.254.80.80. If that doesn't work then it must mean you have the firewall on and it's blocking the traffic. That can be solved by adding a new incoming rule for the program or port.
i want to have a URL like this one (https://www.ooklnet.com/files/381/381489/video.mp4) where when you click it and itll play the video. Thing is this isnt my website or video. i tried my URL which i thought was corrct (http://54.XXX.XXX.238/srv/ProductVideos/lazar108#hotmail.com/s/s_7s.MP4) and it gives me this error:
The requested URL /srv/ProductVideos/lazar108#hotmail.com/s/s_7s.MP4 was not found on this server.
I know for a fact that theres a video in the file path on my server. Proof:
(I need this URL for my android app so i can display the video in the app.)
How can i create a link like this one (https://www.ooklnet.com/files/381/381489/video.mp4)?
I have a Ubuntu 14.04.4 server with AWS EC2!
Any help would be appreciated!!
Thank you!
1) your EC2 has to have security groups open to allow any access to port 80 from the Internet
2) your EC2 has to be running some web server software such as apache
3) apache needs to be configured to serve files, check the document root
4) apache needs to be configured to correctly send mp4 with the right mime type headers see this answer Apache not serving .mp4 files correctly - shows the contents of the file rather than a download prompt
If it is apache ( and not nginx or another web server) you are using check the access log file /var/log/apache2/access.log and the default error log /var/log/apache2/error.log
I am testing facebook app from android mobile/emulator. For this I added a domain like,

"Reason : The URL could not be found."
How to access local domains from android webview or browser without using IP address. I cannot give IP address in facebook domain name fields.

I created a worklight application. I tried running that application on android emulator and i am getting the following error.
[http://localhost:8080/apps/services/api/MyFirstApp/android/query] Host is not responsive.
Try to manually access the URL through the android emulator browser to verify connectivity
So i tried to enter the same url in the emulator browser, i got the following text:
/*-secure-
{"WL-Authentication-Failure": {"wl_remoteDisableRealm":{"reason":"Login Failed}}} */
Can someone help me with this?
I am using Android OS version: 4.2.2, API level: 17
I haven't changed any application settings myself..
I am trying to go to a basic login page with the url "https://jazz.net/jazz/auth/j_security_check"
This is my adapter XML:
<wl:adapter xmlns:wl="worklight.com/integration"; xmlns:http="worklight.com/integration/http"; xmlns:xsi="w3.org/2001/XMLSchema-instance"; name="RQMAdapter">
<displayName>RQMAdapter</displayName>
<description>HTTP type Worklight Adapter for jazz server</description>
<connectivity>
<connectionPolicy xsi:type="http:HTTPConnectionPolicyType">
<protocol>https</protocol>
<domain>jazz.net</domain>
</connectionPolicy>
<loadConstraints maxConcurrentConnectionsPerNode="2" />
</connectivity>
<procedure name="loginToRQM" />
</wl:adapter>
This is my scenario:
I have a requirement where I need to read information about the projects from jazz.net for a user. They are all available on the jazz server within an XML file. I need to process it to a mobile device to make it available on hand held device... So, now I am told that i will have to download some of the files from the server, so i need to have file IO on my app. I learned that we need to write this part using a Cordova plug-in in Worklight.
please let me know what else is needed for the solution... thank you
Make sure to place the actual IP address of your server machine:
Change the value for worklightServerRootURL in the file
application-descriptor.xml (located at: yourProject\apps\yourApp)
Build and deploy
Right-click on the generated Android project >> Run As >> Run application
If you are using using Worklight 5.0.5, make sure to upgrade to 5.0.6, where a fix is available when only API Level 17 is installed.
As for going to that URL, you need to explain where exactly you're trying to go to it from, and how... you need to be more descriptive. It sounds to me like you haven't gone through the Getting Started material. Please do.
I had the same problem.
I have solved it by using the real IP address of the server in the WL app instead of using localhost:
When the emulator is running your app, press the Menu button.
Select to change your server URL
Remove "localhost" and use the IP address.
Accept and try again.
This fixed my problem.
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 :
Download App
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.
Sometimes you have no access to apache configuration files like /etc/mime.types, especially on the shared servers. You can create file .htaccess (or open if it already exists) in your root directory and add the following string:
AddType application/vnd.android.package-archive .apk
Hope it helps.
