Phonegap native android plugin
i try to get my native android plugin on phonegap / cordova 3.0.0 running but i does not work,
the error from ripple: Uncaught ReferenceError: torch is not defined
the call from the index.html
<button onclick="torch.shine(200);">dummy</button>
the plugin.xml
<!-- android -->
<platform name="android">
<config-file target="res/xml/config.xml" parent="/*">
<feature name="Torch">
<param name="android-package" value="org.holzi.torch.Torch"/>
<param name="onload" value="true" />
</feature>
</config-file>
<js-module src="www/torch.js" name="Torch">
<clobbers target="torch" />
</js-module>
<source-file src="src/android/Torch.java" target-dir="src/org/holzi/torch" />
<config-file target="AndroidManifest.xml" parent="/manifest">
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.CAMERA"/>
</config-file>
</platform>
the torch.js in the www folder of the plugin
var exec = require('cordova/exec');
/* constructor */
function Torch() {}
Torch.shine = function() {
exec(
function(result){ alert('ok: '+reply); },
function(err){ alert('Error: '+err); }
, "Torch", "shine", ['200']);
}
var torch = new Torch();
module.exports = torch;
and the Torch.java
/*
*/
package org.holzi.torch;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;
import android.content.Context;
import android.os.Vibrator;
import android.hardware.Camera;
import android.hardware.Camera.Parameters;
public class Torch extends CordovaPlugin {
Camera camera;
Camera.Parameters Parameters;
public Torch() {
}
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
if (action.equals("shine")) {
this.shine(20);
}
else {
return false;
}
// Only alert and confirm are async.
callbackContext.success();
return true;
}
public void shine(int time) {
//Torch torch = (Torch) this.cordova.getActivity().getSystemService(Context.VIBRATOR_SERVICE);
//torch.shine(time);
camera = Camera.open();
Parameters p = camera.getParameters();
p.setFlashMode(Parameters.FLASH_MODE_TORCH);
camera.setParameters(p);
}
}
i solved it, here the code if anyone else have the same problem:
the index with the javascript
<!DOCTYPE html>
<html>
<head>
<title>Notification Example</title>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is ready
function onDeviceReady() {
// Empty
}
function shine(torchOn) {
navigator.notification.shine(torchOn);
}
function alertTorchError(message) {
alert(message);
}
</script>
</head>
<body>
<p> </p>
<p> </p>
<p><a href="#" onclick="shine(true); return false;">AN</a></p>
<p> </p>
<p> </p>
<p><a href="#" onclick="shine(false); return false;">AUS</a></p>
</body>
</html>
the js file with the exec
var exec = require('cordova/exec');
module.exports = {
shine: function(turnOn) {
exec(null, function(error) { alertTorchError(error); }, "Torch", "shine", [turnOn]);
},
};
and the java file
package org.apache.holzi.torch;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;
import android.content.Context;
import android.hardware.Camera;
import android.hardware.Camera.Parameters;
import android.content.pm.PackageManager;
/**
* This class provides access to the Torch on the device.
*/
public class Torch extends CordovaPlugin {
Camera camera;
Camera.Parameters Parameters;
boolean hasFlash;
/* Constructor */
public Torch() { }
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
if (action.equals("shine")) {
hasFlash = this.cordova.getActivity().getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH);
if (!hasFlash) { callbackContext.error("no torch found"); }
else { this.shine(args.getBoolean(0));
}
}
else {
return false;
}
return true;
}
//--------------------------------------------------------------------------
// LOCAL METHODS
//--------------------------------------------------------------------------
public void shine(boolean turnOn) {
if (camera == null) { camera = Camera.open(); }
if (turnOn) {
Parameters p = camera.getParameters();
p.setFlashMode(Parameters.FLASH_MODE_TORCH);
camera.setParameters(p);
}
else {
Parameters p = camera.getParameters();
p.setFlashMode(Parameters.FLASH_MODE_OFF);
camera.setParameters(p);
}
}
}
I don't know my answer could help you or not ,but I encounter this error many times.The following is my code use cordova1.7.0 one years ago, this error not in your java code.
var Music = function() {};
Music.prototype.exec = function(action, args, successCallback,errorCallback) {
if (typeof successCallback !== "function") {
console.log("GetResource: successCallback is not a function");
return;}
console.log("JS function execute --OK");
if (errorCallback && (typeof errorCallback !== "function")) {
console.log("GetResource: errorCallback is not a function");
return;}
PhoneGap.exec(successCallback, errorCallback, "MusicPlugin", action, args);
};
navigator.music=window.music = new Music();
then, register the plugin in the XML file like this:
--your plugin package--
<plugin name="MusicPlugin" value="***.***.***.MusicPlugin"></plugin>
finally,you should invoke this variable after the doucument's 'deviceready' event.
document.addEventListener('deviceready',function());
