问题:

i try to use this plugin and followed the instruction given in the readme.md file.

1)here's my html file

<!DOCTYPE HTML> <html> <head>     <title>TryMakan Video</title>     <link rel="stylesheet" href="style.css" /> <script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script>     <script type="text/javascript" charset="utf-8" src="video.js"></script>     <script type="text/javascript"> function playVideo(){             window.plugins.videoPlayer.play("http://www.trymakan.my/wp-content/uploads/2011/09/NASI-AYAM-BEREMPAH-KAJANG.mp4");         }  </script> </head> <body> <a href="#" onClick="playVideo();">play</a> </body></html>

2) here's my plugins.xml which is located in xml folder

<?xml version="1.0" encoding="utf-8"?> <plugins>     <plugin name="VideoPlayer" value="com.phonegap.plugins.video.VideoPlayer"/> </plugins>

3) i've also copied the VideoPlayer.java into this folder src\com\phonegap\plugins\video

4) additionally, some said I also need to add the plugin into AndroidManifest.xml file, so this is a snippet of it

<application         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/AppTheme" >         <activity             android:name=".MainActivity"             android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale"             android:label="@string/title_activity_main" >             <intent-filter>                 <action android:name="android.intent.action.MAIN" />                 <action android:name="com.phonegap.plugins.video.VideoPlayer"/>                 <category android:name="android.intent.category.LAUNCHER" />             </intent-filter>         </activity>     </application>

but still, when I click on 'play', log cat will return this error

08-08 04:54:15.823: I/Web Console(309): Error: Status=2 Message=Class not found at file:///android_asset/www/cordova-2.0.0.js:938

update1: here's where the VideoPlayer.java is located

here

I don't see the VideoPlayer.java under Gen folder, does that means it's not compiled? Could this be the problem? If yes, how to solve it?

update2: I checked bin folder, and there VideoPlayer.class under bin\classes\com\phonegap\plugins\video so the VideoPlayer.java is actually compiled

回答1:

the problem is your plugins.xml.

it appears in one of the recent PhoneGap release, the plugins.xml has been removed and you have to add the line in res/xml/config.xml instead.

so try adding the tag <plugin name="VideoPlayer" value="com.phonegap.plugins.video.VideoPlayer"/>

to res/xml/config.xml not to plugins.xml

回答2:

If the error shown in the log is

Class not found at file:///android_asset/www/cordova-2.0.0.js:938

The best way is to check which class is causing the error. For those who still get this error message, try the following trick.

Open cordova-2.0.0.js in an editor.
Replace code on Line 938 i.e.

console.log("Error: Status="+v.status+" Message="+v.message);

with

console.log("Error: Status="+v.status+" Message="+v.message+" service="+service+" action="+action);
Run the app again and check the console for the above error. You can see the plugin which causes the error in service=XYZ where XYZ is the plugin name.
Check if the section in your config.xml file has any entry for the XYZ plugin.
Add the XYZ plugin if not found.

I have had this error because of a missing plugin. I Added

<plugin name="Device" value="org.apache.cordova.Device"/>

to the config.xml file and it fixed it.
