HTML5 video tag in my Phone gap Android application


Here I am successfully running HTML5 <video> tag in my Phone gap Android application…
First thing here I succeeded in Android 3.2 version

There are two ways for running video by using <video> tag




1)      By using StrobeMediaPlayer

2)      Without any Player 

1)      Using StrobeMediaPlayer

For that I followed these steps.

1)      Download the StrobeMediaPlayer from the internet
2)      Findout the lib folder in ur downloaded zip file, that lib folder contains two folders (jquery , jscolor) and required js and css files
3)      Then add the lib folder in ur www folder



Required js files:
1)Profiles.js(Required)
2)devicedetection.js(Required)

3)jquery-1.5.1.min.js(Required)

4)jquery-ui-1.8.14.custom.min.js(optional) it displays video time

5)jquery.strobemediaplaybackhtml5.js(Required)

6)StrobeMediaPlayer.js(Required)

Observe above xml file addded android:hardwareAccelerated="true"  attribute in ur < application> tag



1) Without any Player


Here I don’t want to use any player for running html5 video tag for that I do the following steps

1)change the androidManifest.xml file

a)      In androidManifest.xml file i added the android:hardwareAccelerated=”true” for <application> tag
b)      Added code for doing PluginState True in Java file
The following code is added in java file after the super.loadUrl();

WebSettings settings = appView.getSettings();
settings.setPluginState(PluginState.ON);

When i opened  configure Tomcat  it showing "access denied unable to open the service tomcat7" error






I would suggest you to follow these simple steps for the easy solution.
1.Use tomcat7w.exe to always start as an administrator. 2.Right click on the tomcat7w.exe which is in'bin' folder of the tomcat installation. 3.Select 'Properties', then in 'Compatibility' tab under 'Privilege Level'. 4.Select 'Run this program as an administrator'.
Hope this helps thanks.

Resolution for “No buffer space available (maximum connections reached?): JVM_Bind” issue

I hit this issue recently which occurred on only one windows 7 host. The error was caused by this hard to guess reason (http://support.microsoft.com/kb/196271). The default number of ephemeral TCP ports is 5000. Sometimes this number may become less if the server has too many active client connections due to which the ephemeral TCP ports are all used up and in this case no more can be allocated to a new client connection request resulting in the below issue (for a Java application):
