paypal payment with cordova plugin

I'm trying to use paypal payment in my cordova application.
For that I used this Paypal cordova plugin. I followed all the instructions mentioned there, but I get these errors:
01-13 05:18:06.650: E/PluginManager(2112): Uncaught exception from plugin

Can any one help me to figure out this problem?

I resolved the problem.
In the process of installation of the plugin there was a problem.
So that I referenced the file cdv-plugin-paypal-mobile-sdk.js in the paymnt.html page and it works now.

Phonegap 3.2.0 "Unfortunately, AppName has stopped." dialog when closing app

When I close my app, I get a dialog box saying "Unfortunately, MyApp has stopped." and an OK button. By closing, I mean pressing the back button from the first screen. The app does close fine, but then this dialog appears a few seconds later.
I'm using PhoneGap 3.2.0. It didn't happen prior to updating to 3.x.x. I'm not sure exactly which version after this is the culprit.
The LogCat in Eclipse puts out this when it happens:

Any ideas?
Until now, I've always been using the line
navigator.app.exitApp();
to close the app if I detect that I'm on the index.html page when the back button is pressed.
I tried instead to remove the backbutton listener and restore the default behaviour when the back button was pressed. It still results in the same problem.
Here's some shortened code snippets:
$(document).ready(function ()
{
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady()
{
document.addEventListener("backbutton", backButton, false);
});
function backButton()
{
var currentLocation = window.location.href.substr(window.location.href.lastIndexOf("/")+1);
switch (currentLocation) {
case 'index.html':
navigator.app.exitApp();
break;
}
Update 2014/01/13 16:00:
Not sure if it is any help, but I've noticed that it doesn't give any errors if I comment out the script src="cordova.js" from index.html.

In the file Device.java replace the content of OnDestroy with this
if( this.telephonyReceiver != null )
this.cordova.getActivity().unregisterReceiver(this.telephonyReceiver);
Warning: This is hiding the original problem where the BroadcastReceiver isn't being registered properly from what I got from the logcat. Adding the permission to the AndroidManifest.xml like suprnova said should've worked.
But if you don't need to know the phone state, ie, if you're getting a call, or something like that, and you need a quick fix.
Warning 2: When the next phonegap version comes out, this may get overridden.

Judging by your LogCat, the problem lies in the Device.java file, and looking at the source here, the class registers a BroadcastReceiver to check the phone state.
Make sure you have added:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
to your AndroidManifest.xml.

this is the cause.

UI cant be updated from doInBackground
You should provide the code as well , specifically for the relevant part.
Here is an example of an approach that can be used
private class SaveProfile extends AsyncTask<String, Void, Boolean>{
#Override
protected Boolean doInBackground(String... params) {
//---------- so your stuff here.... non ui related
Log.v("response from saving",response);
if(response.equals("1")){
return true;
}else{
return false;
}
}
protected void onPostExecute(Boolean result) {
if(result) {
//------ UPDATE UI HERE
Toast.makeText(ProfileCompanyActivity.this, "profile saved", 2500).show();
}else{
Toast.makeText(ProfileCompanyActivity.this, "an error occured", 2500).show();
}
}
}

First you must Understand the Concept of AsynTask in android...
1) you cannot update or change your UI element in backGround thread i.e doInBackGround()
2) use onPreExcecute() or onPostExcecute() to change or update your UI element
And to be Sure you are accessing UI element into doInBackGround
Check out this Example to Understant how the Methods work
Hope this could help....

Set brightness of flash in Android

In my program I tested this:
try {
FileWriter mWriter = new FileWriter("/sys/class/leds/flashlight/brightness");
mWriter.write(125);
mWriter.flush();
} catch (Exception e) {
Log.e(TAG, "setFlashlightEnabled failed", e);
}
I have this in the log :

I have tested in ADB Shell this :
echo 125 > /sys/class/leds/flashlight/brightness
It works in root but not in normal mode.
What is the solution to change the flash output without being root?

It belongs to system and is being protected by system, so you must be a root to access.Also all Android devices dont have the same flashlight design in structure, sample like: in HTC device, it supports API for handling 3 different brightness level, but others don't...
