Android :: Implement Javascript SetTimeout Function In Java
Nov 1, 2010
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:.....................

I have put HTML document into a string variable and load it by using webView.loadDataWithBaseURL(null, htmlString, "text/html", "utf-8", null).
After that, I tried two ways and want to execute javascript function "exec()" by using
1. webView.loadDataWithBaseURL(null, "javascript:exec()", "text/ html", "utf-8", null) -> This will overlap the content of previous "htmlString" and shows "javascript:exec()" on the screen.
2. webView.loadUrl("javascript:exec()") -> There will be "Can't find variable: exec line: ..." in Logcat
I have tried to output "htmlString" to a file located in sdcard, and tried to use webView.loadUrl("file:///sdcard/xxx/a.xhtml") + webView.loadUrl("javascript:exec()").
And...it fails again! how to execute javascript function after loading html content by "loadDataWithBaseURL"?

I've been following a discussion on the apparent lack of JavaScript and Java on Android browsers. One of my hot button applications requires either JavaScript or at least the ability to run a .jar file in order to save data. No one in the other discussion has been able to find a Android browser capable of supporting this application (TiddlyWiki)..

I am writing a hybrid web/native app and ran into issue. My app downloads a music file via Java code, and needs to update a Javascript download progress bar in the WebView in real time.
My understanding is the only way to call Javascript from Java is via the WebView's loadUrl method.

I have found that there is a significant lack of documentation of WebView's ability to communicate with Java via WebView.addJavaScript() method. First, the debug document http://developer.android.com/guide/developing/debug-tasks.html#Debugg... appears to no longer work. Second, what object types should we expect when going to and from JavaScript. I have done some trial and error and it appears that complex types can cross the boundary, for example java.util.Vector. However when a Java method returns a byte array to JavaScript it has a type of undefined and I have been unable to coerce it to any other type. Finally, there is great potential with this interface and with some more attention we could go far.

Why below code is throwing nullPointer exception in last line (when accessing javaInterface.mValue) This line through NullPointer, so basically it is not being set. even though the javascript is correct and has been verified using FireBug that it returns expected string.
There are few lines above this code chunk but it is irrelevant this problem

I believe that it's possible to call Java methods from (PhoneGap) Javascript. Anyone knows how to do that?? (I know how to do it by changing the source code of PhoneGap, but I'd avoid that)

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!

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'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.
