Android :: .NET Trim Function In Java?
Aug 8, 2010
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?

I 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!

A while ago I tried to work out how to checksum a function at runtime. As I remember, I failed due to some missing functionality of the class loader from vanilla java. Has anyone managed to do this ?

I'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:.....................

We are converting apps to Android from .NET
Is there a Java equivalent of the .NET Path.Combine() function?
Currently we check the / on each folder etc before building paths.

My point is to be able to call a 2.1 API if it exists, while the application should be able to run in 1.5
Specifically, I am making a GPS application which would like to call android.location.LocationManager.addNmeaListener if available. My problem is that this call takes as parameter an abstract class (GpsStatus.NmeaListener) which I cannot pass directly to Class.GetMethod (or my application won't work in 1.5). What I am currently trying is a) to create a wrapper class for GpsStatus.NmeaListener:......................

I am calling a method of another .apk file dynamically at runtime in my application. I can execute it successfully if method does not contain any variable which is defined outside of that method.
But if I am using the variables which are defined outside that method ( in the same activity or same .apk) then my application throws "java.lang.reflect.InvocationTargetException" at runtime.
For e.g. if method defines as ,

Is there a way to remove specific entries in the default phone book on the Dinc? If you have multiple phone numbers entered for a contact, all of them appear as as option for sending a text message. I would like to remove the "send message" entry for all non-mobile numbers. I see that there is a default phone number option for each contact. Is the same option to pick a default number for messaging? If so, that would help the mobile number for sms stand out in the list. I have sent a few texts to home or work phone numbers accidentally and I am trying to idiot proof my contact lists.

I'm using a galaxy note 10.1 2013 edition, and was wondering if there are any apps that allow the same functions of the 4.3 trim (clearing cache). If there aren't any, I don't mind having to manually clear cache, but is it possibly to do it without rooting?

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

I was going through the code for Activity.java and ApplicationContext.
Both these classes define many functions of Context Interface. Take for example startActivity.java
Activity Class has its own implementation of startActivity ApplicationContext class also has an implemenetaion of startActivity.
Now there are 2 observations...
CODE:..........
Questions: 1. Who uses ApplicationContext class? 2. Does Activity class ever deal with ApplicationContext class (as given in the javadoc comments of ApplicationContext.java).
