Android :: Android / Java - Call Function In Separate *.java File?

Aug 16, 2010

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!

Android :: How To Call Java Methods From C++ In JNI?

Oct 10, 2010

So I'm writing an Android app which uses a large c++ library. I have everything working so that the java app can call the c++ delegation methods, but I'm finding myself wishing I could log messages from c++ to the Android log. This is easy from java, but I'm at a loss as to how to call a java method from c++. My searches found methods for opening a jvm from c++, which is not at all what I want to do. Ideally, I'd like to pass a log method pointer to c++, which could then be used whenever I wanted. Of course, java doesn't support method pointers.

Making a simple app for my android.

how do I call the value of input1 in Java and then perform a calculation on it?

For example...

suppose input1 = x

x + 5 or x*2

and for that matter, how do I have the resulting value appear as constantly updated text output in a specified place on the UI?

Android :: Why AlarmManagerService.java Call - Remove - First In A Set - Alarm

Jul 13, 2010

It was a bit baffling (Probably there is a good reason, and it doesnt take much to baffle me)

AlarmManager am; ... PendingIntent pi;

am.set(pi, ...) at 11pm am.set(pi,...) at 2pm

Same "pending intent" with the same intent and request code, in otherwords they resolve to same intent on equals.

Although I know what happens (being the latest one takes precedence), I would have expected my broadcast receiver to be called twice.

I thought something funny is happening in the PendingIntent.

However when I looked at the AlarmManagerService.java I have noticed that the "set.." methods are calling a "remove" using the PendingIntent that is passed in, essentially cancelling the one before.

Android :: Service Unable To Call Java Class Methods / Way To Fix?

Jun 22, 2010

Hi, custom classes which are part of a framework, so nothing graphical. One of those (singleton) classes is a Logging class which send logs to my server. I noticed that even though I can call the classes methods in my service it actually won't be logging anything... In my specific example it's osmething like : Logger.getInstance().log("Whatever I want to Log"); Obviously the getInstance is a static method so it can be accessed from anywhere within my project right away.. I was wondering though why this method for example isn't getting called ? Also how do I debug a Service ? Btw I am using of IPC from one of my Activities which gets bound to the service and can start/stop the music for example...

Android : Program Crashes When I Call A Class From Another Java File

Oct 26, 2010

I am new at android development and java programming, but I have decided to program a drinking game app in android. This app basically simulates a deck a cards, a player clicks a button to draw a card then based on the card thats drawn the player plays a drinking game (ie takes 1 drink, takes 2 drinks ect).

I have the main program in one java file, and the code that shuffles the card deck and puts the card sequence in an array in other java file. My problem is that whenever a class from the other java file (classicMode.java) is called from the main program (fubar.java), my android program crashes and gives the error : "The application Drinking Game - FUBAR (process com.games.dg) has stopped unexpectedly. Please try again". Code...

Android :: Way To Store XML Data In A Java Object From A SAX Parser

Jun 21, 2010

I have created a class with 3 sub classes in Java. The 3 sub classes contain variables to store information from my XML document. I am able to store in the first two for there are only single instances of the data in the XML. The third class contains variables that repeat multiple times. I want to store an object of "third class" objects. I also have a SAX parser class. I am doing this within an Android environment (1.6).

Does this make enough sense without displaying any code?

Android :: Java Reflection To Call Higher API Level Function / Abstract Class

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:......................
