Android :: Global Settings Variable For Application
Nov 3, 2010Is there a way to have an global settings variable for an android application, which is accessable as well from any help java classes without giving them context?
I try to explain what I mean.
I have an application version as string value in strings.xml I can get its value from every android activity, but not from help java classes withought giving context What I do now, is saving it in a static variable of my first activity, but it seems, that sometimes it will be erased and set to null.
Android :: Android.app.Application Global Application Variable Store
Feb 1, 2009I want to create a global variable store for a list of user defined objects. I have a LinkedList of Feed (a user defined object) that I need to be made available to a new Activity that is created. This list is displayed using a ListView and so when an item of the ListView is clicked, I need the correct Feed index to be 'passed' to the new Activity. I have no problem doing this as I create an Intent and then pass the id of the selected row. I need the new Activity to have access to the LinkedList of Feed objects.
There are different ways to do this (explained here - http://code.google.com/android/kb/framework.html). I want to use the option (quoted from link above): The android.app.Application class The android.app.Application is a base class for those who need to maintain global application state. It can be accessed via getApplication() from any Activity or Service. It has a couple of life- cycle methods and will be instantiated by Android automatically if your register it in AndroidManifest.xml.
I want to use the above method as I could then fill the LinkedList at application start and then use it throughout without any duplicates etc. Does anyone know how the android.app.Application class can be used as a global variable store that can be accessed from other classes? I cannot find any more information on this method of passing information between Activities within a single application. Any information regarding passing user defined objects would be useful and specifically how to get the above idea to work.
Android :: Changing Variable Affects Indirect Variable (value Vs Reference)
Sep 26, 2010Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

Mar 16, 2010I have a preferences.xml that looks like this:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference android:name="Sample" android:enabled="true"
android:persistent="true" android:summary="Sample" android:defaultValue="3.0"
android:title="Sample" android:key="sample" /> </PreferenceScreen>
When I do sp.getString("sample", "3.0"), it works fine and returns a string, but it shouldn't be a string, it should be a float. Running sp.getFloat("sample", 3.0f) throws a ClassCastException because it is a string. What should I put in the XML so that the preference is stored as a float?

Jun 29, 2010A few days ago I was struggling to find a way to use custom intents for my alarms. Although I got clear answer that I have to customize the Intents based on some unique ID eg. setAction() still have some problems.This can happen more than once for a contact. And when the second message is generated, the notification is raised well (message is fine there) but the intent when the user actions the notification it uses old data, so previous message is passed and not the brand new message.So someway the intent is caching and reusing previous extras. How can I make it unique per contact and per action?

Activity A / B - Where To Declare Keys Of Bundles
Jan 27, 2012I have a little doubt, I spend data from Activity A to B with a bundle in the intent.Where I should declare the keys? In Activity A or B? Only to avoid confusion, I'm talking about the string that defines the data that will be set in the Bundle.Ex: public static final String KEY = "MyKey";
I declare always in the Activity A, but I think that if I could let all the keys in a file would be better, like keys.java or something like that.Obviously, this is nothing that is generating errors, just a doubt about convention, a thing that I consider very important in software development.

View 2 Replies View RelatedAndroid :: Excessive JNI Global References Seen On 1.5 But Not 2.1
Aug 11, 2010There's a bug in my network code so that when the server's not available the Android client tries over and over to connect. On 1.5 (emulator) this results, within a minute, in an "Excessive JNI global references" error where the leaked object is a small (20 byte) boolean array. The same code on emulated 2.1 runs for as long as my patience lasts. Is there any possibility the leak is in my code and not an Android bug that's been fixed since 1.5?

Jun 26, 2010I'm getting null pointer exceptions when I try to initialize Button and EditText objects in global scope, can't figure it out. I've commented out everything but the bare minimum for the app to display my layout, but this still causes a crash: private EditText addmoney = (EditText)findViewById(R.id.addmoney);
R.id.addmoney definitely, definitely exists. So what the heck? Is it impossible to declare EditText in global scope? I need to be able to call it from both onCreate and onPause in a class extending Activity, is there maybe another way I should be doing this

View 3 Replies View RelatedAndroid :: Use SWIG With Droid NDK - Weak Global References
May 11, 2010I'm currently working on Android NDK, porting my libs, and I'm using SWIG (Simplified Wrapper and Interface Generator) that is a great tool to generate JNI code around my C/C++ headers for Java.
However, there is a big issue using it on Android, 'cause of incomplete JNI support : 'Weak Global References' are missing. Unfortunatly, SWIG is waiting for a full compatible Oracle/Sun JVM, and use this feature with its 'director' option (for proxy class creation).
For now, I comment each time, in a (kind of) bad way, the use of weak global references in my generated C/C++ wrapper files (4 lines in my case). I think it is really a shame that we can't use (one of) the best wrapper with Android NDK just for one missing feature.
I read that Google Team will add it in future release : "NewWeakGlobalRef and DeleteWeakGlobalRef are not implemented. The VM supports weak references, but not JNI "weak global" references. These will be supported in a future release." (http://android.git.kernel.org/?p=platform/ dalvik.git;a=blob_plain;f=docs/jni-tips.html;hb=HEAD)
So my question is, does anybody know when 'Weak Global References' will appear in Android NDK ?
