How To Generate And Use Variables In Different Switch Statements

Jan 29, 2012

I'm trying to encrypt a text with DES algorithm using Bouncy Castle library. I have written the following code:

Code:

try{
KeyGenerator kg=KeyGenerator.getInstance("DES");
SecretKey key=kg.generateKey();

[Code]....

Then depending on the user selection, inputText is encrypted or encText is decrypted in the switch statement. Both encryption and decryption blocks share the same "keySpec" and "Cipher" variables generated in the above code snippet. However, the compiler says that keySpec and Cipher cannot be resolved which I understand is that the keySpec and Cipher generated cannot be seen by the statements inside the switch blocks. How can I make it work?

Android :: Switch Statements In Android

Oct 13, 2010

the idea is that once if/else determines that the onTouch event was caused by clash and the switch statement then determines what to do based on the action. i don't know if the problem is that the switch statements are not returning true and that may be related to the problem. when i add a return, eclipse says that the code is unreachable which i don't understand. i was under the impression that you can't break out of a switch without break. what's actually happening is that the first sound will loop but the code never seems to detect the action up when the button is released and so the sound plays forever.

Android :: How To Get Debugging Statements In Eclipse

Apr 20, 2010

I've read the lame documentation, and checked other answers.I'd like my Android app to print some debug statements in the logcat window of Eclispe. If I use the isLoggable method on the various types of debug levels on the Log class, I find that WARN and INFO are returning true and Log.i do not produce any output.Does anyone know which gotchas I've missed?And just to vent, why should this be hard? I've published apps for iphone and bberry and while appreciate the use of java, the platform is reeking of too many "genuiuses" being involved. I suppose Activities and Intents are very flexible, but why? I just want to put up some screens, take some input and show some results. The bberry pushscreen and popscreen is a lot less pretentious.

HTC EVO 4G :: EVO Under Sprint Family Plan - Call And Internet History Online And In Statements

Jul 16, 2010

Is there any way to secure call history for one of the phones in family plan, or will the primary account allways have access to every call any phone makes via the statements or online access?

Also, How much browser and download history information is available in statements and online for all phones on the family plan?

So is anybody doing seamless VIOP from the EVO on 3g? If so how? will VOIP calls show up in any logs outside the phone?

Any ETA on when it will get Skype without some third party? How about true multitasking while on Sprint Voice Call? I honestly can't believe it does not offer those two, I'm sure millions will jump when those come in.

BTW, I tested tethering with PDANet on 3g last night .. It worked great - not crazy fast, but good enough in a pinch.

I'm still waiting for 4g in the big city I live in.

For me, these are the monster items I've been waiting for.. Fast tethering, Voip Video and voice client , multitasking with voice.

One cool feature I will use tons is Voice command and Voice Typing.. they work awsome.

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 :: 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 :: All Static’s 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.

General :: ADB Can't Open Files From Folder Used In System Variables

Feb 13, 2014

I have installed ADB and the whole Android SDK to root my asus transformer infinity (tf700t). I have taken all the steps every forum on the web describes: installing everything trough the manager, adjusting the path in the System Variables, and finally it getting it to work together with my tablet. However, when I try to flash/copy/install files from my folder (yes these files are in the same folder as adb.exe and fastboot.exe, which is the folder I used in the System Variables) It can't either find these files or it cannot open these files. When i put in the command 'path' however. I does give me the path where the files can be found.

Android :: Sharing Global Variables Across Activities - Problem When Using Webview

Jun 23, 2010

I'm sharing some variables accross activities by using a class like this :

CODE:..........

Then I'm using these variables anywhere across my multiple activites with ...if (Globals.hint2_stockview_valuation == false) {....}

Pretty basic and it was working fine untill ...

I introduced some webview stuff like this:

CODE:...........

And here's the News_Webview.class:

CODE:............

The problem now is that, when it "comes back" from this Activity, it looks like my Globals variables have disappeared ?

if (Globals.hint2_stockview_valuation == false) {

fires an error :

06-23 12:14:03.443:
ERROR/AndroidRuntime(2611): Caused by:
java.lang.NullPointerException

2 Questions then:

Should I use something else than this "Global" class to share variables across activities ? Is it just bad practice to do this ?? I know that I can use the preferences but I thought it was quicker to do it this way (no need to "read" the preferences everytime I start a new activity ...Should I "get back" my savedInstanceState in some way when my activity returns from the News_Webview.class ?

Android :: Previous Set Instance Variables Null When Activity Resumed

Apr 20, 2010

I am using an Application object to store app-wide instance data--data that I need to remain in existence for the entire lifetime of the app, so the Application class seems like the proper place to put it. I have just finished reading this thread http://groups.google.com/group/android-developers/browse_thread/threa... that goes into pretty good detail and receives confirmation from Googler hackbod as to how the Application class performs--and from that info it seems this strange behavior I am receiving should not be happening...

Basically, every once in a while when I resume my app in any of its Activities (it is still running in memory so onCreate is not called) I get NullPointerExceptions because instance variables in my Application class are returning null when I request them from my Activity (via a getter method in my custom Application class). It seems as if sometimes Android saves the states of my Activities but deletes all my instance variable data... This can't be an Android problem--there must be something wrong with my code.

Has anyone else ever ran into an issue of this kind? Any ideas as to what may be causing this? I'm not going to post my code here as that won't help anyone, but hopefully someone can point me in some helpful directions.
