Android :: Get User Defined Environment Variables?

Sep 20, 2010

I would like to use self defined Environment variables in my source code.

I use System.getenv() to do this and the code line looks like this. Log.d("MyTest","== MyEnv " + System.getenv("AP") + " ANDROID_ASSETS:" + System.getenv("ANDROID_ASSETS"));

Before I execute my code I define my AP variable with export: export AP="12345" and the this is my output of set command

ANDROID_ASSETS=/system/app
ANDROID_BOOTLOGO=1
ANDROID_DATA=/data
ANDROID_PROPERTY_WORKSPACE=9,32768
ANDROID_ROOT=/system
AP=12345

Then I execute my code and I get this line from logcat

D/MyTest( 5363): == MyEnv null ANDROID_ASSETS:/system/app

The value for my defined Environment variable is null. Any suggestions on why it didn't work?

Android :: Development Mode And Maintaining Environment Variables

Nov 16, 2009

I'm building an Android application and would like to maintain a few environment variables that I can tweak depending on whether I'm in development mode or release mode. For example, I need to invoke a web service and the URL will be slightly different in either mode. I'd like to externalize this and other settings so I can change them easily based on my target deployment. Distinguishing development mode and release mode environment settings on Android. Are there any best practices or anything in the SDK to assist with this need?

Android :: User Defined Application Properties?

Aug 28, 2009

Where is the right place to specify general user-defined properties, like a host address or a service mail address ? The properties should be accessible from my activities.

I would like to specify such attributes within the AndroidManifest.xml, but there seems to be no elements available for user-defined properties. So the only way may be to put such properties into a resource file as strings or to hide them into the source code...

Android :: Saving ArrayList Of User Defined Objects

Aug 10, 2010

I am working on an application where I am saving the state of an application in an ArrayList. Now, to save this state, I tried to use Serialization. But, somewhere in the user defined object, I am using Button, which is not letting me serialize the entire object. I wanted to know, is there any other way of saving this array list between onPause and onResume? I even tried onSaveInstanceState, but it doesn't have support for Array List.

Android :: How To Check If User Defined Service Is Already Running

Sep 6, 2010

I have a service that is running within the context of my application. It gets invoked at the start of the activity and then gets update when new data is inserted or deleted from the database. The problem is that everytime I start the activity , it restarts the service. As you may have guessed - not a very intuitive design. Therefore I was wondering if there is a way to determine if the service is already running before starting it. I know I can bind to the service but I do not want that since the main activity needs to exits after the database operation is completed. I know for system services, you can get the service details from the application context. How do you do it for user defined service?

General :: Where Are User Defined Fields In Android Contacts

Apr 29, 2012

Have been a long time user of Outlook and Blackberry and store a lot of information in the User Defined Fields. Those fields seem to have been eliminated from all of the Android Contact Apps. I don't see them in Motorola Corporate Sync, Touch Down or Moxier Mail. Am I missing something, can't believe the developers of Android apps would just skip those fields. Any App that I can store and sync those fields. Google Contacts has the fields. I have just upgraded from a Blackberry Bold to a Verizon Droid Maxx. Love the big screen on the phone, struggling with the touch keyboard and really struggling with losing half of my contact information.

Android : Change Variables From Different Classes?

Jun 6, 2010

Before I delve into it, I'm very new to Android and I have just started learning Java last month. I've hit bumps while trying to develop my first simple app. Most of these hurdles were jumped thanks to random tutorials online. MY CODE IS VERY MESSY. Any tips are appreciated.

The question above is quite broad, but this is what I want to do: It's a essentially a blood alcohol content calculator / drink keeper-tracker. Basic layout: http://i.imgur.com/JGuh7.jpg

The buttons along the bottom are just regular buttons, not ImageButtons (had problems with that) Here's some example code ..

It outputs the following to the text view: "Your BAC is -0.017". This is the Bac value for if StandardDrinks was still 0, so obviously there is some problem communicating between the classes.

The other elements of the formula (weight, time spent drinking, and the alcohol %'s and such) are variables because I will ultimately allow the user to change those values in the settings.

I've heard around the water cooler that global variables are not good programming style, but this is the closest I've come to getting it to work..

Android :: Activity Lifecycle And Static Variables

Jul 14, 2009

I just ran into a situation where it looks like a static variable reference is persisted across activity sessions. I didn't expect that because I thought that when an activity exits, it's de-referenced and garbage collected. I am wondering if anyone can shed some (more) light on when the VM eliminates object references for Activities and Services and in particular when static variables get reset to default values?

Android :: Get Variables / Data From One Screen To Another In Phone?

Feb 27, 2010

In android: I'm trying to take data from one activity/screen to another.

Let's say I'm adding two numbers. I layout my first screen (xml) with 2 EditText views, a couple labels, and an 'OK' button. Now, I want to add the numbers that I've input into the EditText views. Let's say I input 2 and 2 (2 + 2 = 4).

Now, when I hit the 'OK' button, I want a new screen/activity to appear and simply show me the answer (4). Do I use global vars to do this?

Android :: Threads Cache Instance Variables?

Jul 3, 2010

I am starting to develop an Android App and have noticed the following behaviour in my test code (not yet designed the real app):

A thread that loops around doing Bluetooth IO accesses an instance variable that is declared in the enclosing class. That instance variable gets set to null by the GUI thread in the onBackPressed() method which also closes the Bluetooth socket which causes an exception in the IO thread (which is what I want).

The odd thing is that if I set the instance variable to null before I close the socket, the IO thread sees the null value, but if I close the socket first and then set the variable to null, the IO thread doesn't see the null value.

The instance variable is being used in a loop in the IO thread and it appears as if that variable is being cached while within the loop. So any changes to that variable by another thread are not visible. Is that possible? If so, is there a workaround to guarantee that the VM will read the value of the instance variable?

Android :: All Staticís Variables Retaining Values When Launching Again

Dec 1, 2009

I have been facing problems to manage statics variables used in my android application. If we exit the application against a particular event (touch or key event -which is must for my app), all the statics variables are retaining the values when I am launching it again. I am invoking Activity.finish() method for termination . I know there is a collection type class available called Bundle and we can use it to save the states of all the statics and get those back when again creating the same activity during relaunch, but it would be a hard task if we want to port some j2me applications to Android because of having thousands of statics variables. Is there any way to kill the application completely including all the statics variable used there?

I tried with System.exit(0) and it works well for Android G1 and G2 (tested in firmware 1.6). But in Android Robyn (prototype) the same causes a major defect ("Activity not responding" popup apears just after exit) and I came to know from android dev forum that calling System.exit(0) is not recommended for termination of an activity.

Android :: Parsing XML And Initializing Static Variables Of Some Class

Dec 21, 2009

I have an application that is driven by a configuration XML: various app properties are loaded at the app start-time by parsing the XML and initializing static variables of some class. The data read from this XML drives different Activities of the application. Presently, I have called the "parsing and the properties-initialization" from the onCreate() of my Main Activity. I have a few questions as regards this case/approach: Should I invoke the app initialization method from the Application Object or is the current approach correct?

What advantages/disadvantages do/would we get/have if I choose to invoke it from the Application object? Do we really need a static class to store app properties? Or can we have all the properties as a static Collection variable in the application object? Parsing a XML(~200 nodes) at app load time might take some time (not sure how long tho); How can I avoid the dreaded ANRs? I am using a Pull Parser.
