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.

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!

I am looking for a simple app to remind me if I have a missed call with a notification sound configured to my preferences. In other works remind me ever X min with sound Y.
I have read a lot of issues with Missed Call so I haven't even tried that one. Anyone having any luck with this app?
I installed executive assistant which does the job very nicely but it also does a LOT more that I don't need/like. I just want something light weight and simple.

I recently got a samsung galaxy s4 mini with android 4.2 I noticed that if I have an alarm set for a specific time, and I happen to be on a phone call at that time, the alarm will not go off. Instead of vibrating and playing the required sounds, it will simply beep a couple times and that's it. I understand that it can't play any sounds while I'm on the phone, but is there any way to at least get it to vibrate at the time of the alarm?

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.
in my xml interface there is a text box in which the user will input a number (for example: 10). the id of this text box is "input1"
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?

I am having an annoying issue with my alarm while I'm on a call. If I'm on the phone and the alarm goes off, it totally disables the phone keypad and basically takes over the screen. It went off today while I was on a call and I couldn't dismiss it in order to get the phone keypad back. Is it my phone (a motorola photon) or something else?

I tried several alarm clocks on my droid, and they all seem to have a problem. if I set alarms for 6:30, 6:41, and 6:52 am. Each with a different sound. If i snooze alarm 1, alarm 2/3 never goes off. i thought all 3 would be seperate, but it seems only 1 can be active at a time. unless im doing something wrong. this happens on the default alarm clock and, better alarm clock.

1. Can I call ADT Layout Editor in my java source file, not by XML file "open with" menu ?
2. When I click "add" button in the outline view of ADT Layout Editor , it will show such a list of UI components as "AbsoluteLayout AnalogClock AutoCompleteTextView Button ....." My question is where it gets this list? Can I config this path to get my customized UI components?

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...

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...

I would like to be able to automatically remove spam callers from my call log and not be notified they called. I've set up a contact that goes directly to voice-mail. I'm using google voice, so I can set the contact as spam, so it will put any voice-mails in the inbox. That took care of the ringing and interuption, but I'd still like a little more opaqueness.
Is there an app that can remove a caller from the log, or at least clear the notification? I've checked out the various call blocker apps, but thus far, I haven't been able to confirm if any can clear the notification. They mainly seem to answer and hang up.

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