Is there any built-in function available in java for removing contents (ex: white space) between XML tags: <student> <name>miya</name> <number>12</number> </student> I want to convert the above document as: <student><name>miya</name><number>12</number></student> by removing the white space?

View 2 Replies View RelatedI want to write an application for Android devices that interacts with the surface and I need to be able to have the Android device display Microsoft Surface Identity Tags. I was able to create a class to draw the Byte Tags using the Byte Tag documentation but all I could find for the Identity Tags was this MSDN documentation and it doesn't include any information about how to draw them. Can anyone point me to some documentation on how to generate Identity Tags programmatically?
View 2 Replies View RelatedI do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!
I have had a problem with no matter what android phone I have. This has been doing it for quite some time but I dealt with it but last night I lost 12 GB of music so here it is:
Whenever I move music in these situations, it will erase all ID3 Tag information (Artist, Album, etc) and all it has is the file name. I had 2000 songs with artist names and all, but when moved it all became unknown artist. Here are the situations:
Galaxy S3: Moving Music from one folder to another (Like from a Download folder to my music folder on external SD). Or from moving music from internal to external or vice versa.
Optimus G: Moving music from one folder to another on the internal storage (Again, like from a download to music folder).
Evo 4G: Just moving from folder to folder.
All this is done with ES. File explorer. I tried other but they do it too. It can not be device specific because it happens on almost any android. All songs are in MP4/MP3 format and maybe some .wma.
In an Android app, I am looking for the functionality of the .NET string function [Trim('aaa')] which will trim off the text "aaa" off a string. I don't think this is natively available in Java and I haven't seen that functionality in Android Java textutil library. Is there an easy way to have a Java app trim a set of characters from the string?

View 2 Replies View RelatedI'm very new to java and am working on my first Android app. I am using the webview demo as a template. I am trying to generate a random integer between 1 and 12 and then call a certain javascript function based on the result. Here's what I have:
int number = 1 + (int)(Math.random() * ((12 - 1) + 1));
number = (int) Math.floor(number);
String nextQuote = "javascript:wave" + number + "()";
mWebView.loadUrl(nextQuote);
So mWebView.loadUrl(nextQuote) will be the same as something like mWebView.loadUrl("javascript:wave1()") I just want to know if what I have here is correct and will work the way I think it will. The application isn't responding as expected and I suspect this bit of code is the culprit.

I am currently trying to integrate a live search functionality in android. I use a customized Autocomplete widget. The widget itself provides me with a threshold to only start a query after a certain amount of characters have been typed in. But what I also want is that a query only starts, say if a user has stopped typing for 2 seconds.
As I load my contents with a AsyncTask I tried blocking the doInBackground function by calling Thread.sleep() right at the beginning. If the user would then continue typing the program would look after an existing task, cancel it and start a new one. This was my idea. But it doesn't quite work the way I expected. Sometimes it sends out queries even if the user is still typing, sometimes queries are canceled after the users stopped typing. Do you have any ideas on this or maybe a better way to solve this? Here are the code snippets:.....................

Is there a built-in intent which will let you pass it the path of an image (png or jpg) and show it full-screen with panning / zooming controls? Basically the same controls WebView has, but only for a single image. I saw that iPhone has something like this, just wondering if there's already something like this on android before writing a new one.

View 2 Replies View RelatedI know I can set DEBUG in Android's ADB by typing:
adb shell setprop log.tag.MyTag DEBUG
What I'm wondering is if there is a way to set debug for all my classes that do logging instead of having to type the above multiple times:
adb shell setprop log.tag.MyTag1 DEBUG
adb shell setprop log.tag.MyTag2 DEBUG
adb shell setprop log.tag.MyTag3 DEBUG
adb shell setprop log.tag.MyTag4 DEBUG
Something like:
adb shell setprop log.tag.* DEBUG
I'm using Eclipse for developing, but I'm currently setting the DEBUG through the command line adb.
Hopefully this will be a simple question for you guys as for the life of me i cant find how to delete tags from shazam on HTC Hero.
