Android :: Make Adapter Class To Choose .Java File Depending On Firmware Version

Sep 1, 2010

What I did was create two .java files. One that can compile and run on a 1.5 phone (SDK3) and then one that works on 2.0(SDK5) So for this example i'll call the 1.5 file ExampleOld and the new one Example. I was wondering if i just made activity like this if it would work sort of like a "portal" and pick the activity to load depending on the SDK so there is no crash or compile errors. Are there any changes I should make to my code? Maybe anyone out there that's had to do this before.

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

Android :: Does The Dalvik File Format - .dx - Support More Instructions Than Java .class File

Apr 17, 2010

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?

As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

Android :: Possible To Put Each Class Into It's Own Java File In Eclispe?

Apr 20, 2010

I'm coming over from C# where I can make a namespace and then have each class placed into its own .cs file if I want, but in all of the examples I've seen for android all of the methods and classes are all in one big java file.

Is it possible to put my classes in to their own java files and then import those classes into a main program java file as needed like I do in C#?

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 :: Thread Class In SDK LunarLander And JetBoy Examples Not Each In Separate Java File / Why Is So?

Sep 9, 2010

Is there a reason why the Thread class in the SDK LunarLander and JetBoy examples are not each in a separate java file, rather than being inside the View file?

It would make things a bit clearer, IMHO. Am I missing something?

Android :: Code Depending On Version Of API?

Nov 24, 2010

In Android I get the version of the SDK easily (Build.VERSION.SDK) but I need to use LabeledIntent only if the platform is newer than 1.6 (>Build.VERSION_CODES.DONUT) I suppose that Reflection is necessary (I have read this link but it is not clear for a class or to me). This is the code but it gives me an exception because in my Android 1.6, the compiler verifies if the package exists even if the condition is not applied:

Intent theIntent=....;
if(Integer.parseInt(Build.VERSION.SDK) > Build.VERSION_CODES.DONUT)
{
try{
Intent intentChooser = Intent.createChooser(intent,"Choose between these programs");
Parcelable[] parcelable = new Parcelable[1];
parcelable[0] = new android.content.pm.LabeledIntent(theIntent, "", "Texto plano", 0);
intentChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, parcelable);
activity.startActivity(intentChooser);
}
catch(Exception e)
{
activity.startActivity(theIntent);
}
} else
{
activity.startActivity(intentMedicamento);
}

Android : Class Generator For Data Classes Used In Java / Droid From Existing Wsdl File?

Apr 3, 2010

Is there any class generators to process web services in Android/Java? I may have to write my own to generate classes against WSDL but I'm trying not to. Also is there one for REST services as well?

If not providing me with discovery service suggestions like disco/wsdl are good enough.

General :: Fujitsu STYLISTIC M532 - Editing Firmware Update File Version Info

Nov 26, 2012

Quick question: Where in the .pkg update package is the information on the build and the version of the update? I sort of screwed up my tablet, I can boot into stock recovery but not much more. ADB won't work, and AFAIK nobody knows how to enter fastboot mode on this thing. Hence, I figured that the only way to reinstall the ROM is to trick recovery into installing an update package that's already installed.

The tablet is Fujitsu STYLISTIC M532.

Android :: In Java, What Does A Reference To Class.class Do?

Jul 20, 2010

I'm building a small Android application, but this is more of a Java question than an android question. Looking through the tutorials there are lines that look like: startService(new Intent(this, MyService.class));

What exactly does the "MyService.class" field represent? Is that just a reference to the class for a template?

For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

Android :: How End User Upgrade Firmware Version?

Oct 7, 2009

I'm trying to understand how end-users will upgrade their device firmware from Android ver. X to X+1. A new build of Android contains system.img and userdata.img (among others). system.img is read-only, so I don't see any problem with simply replacing the user's existing copy. However, simply overwriting userdata.img with a newer version would destroy all of an end-users application data (wouldn't it?).

I'm trying to understand how this process will work for our Android- based device. It seems that the designers of Android must have had a plan for doing this without the user losing all of their data, but I can't find any documentation about this. Googling for this information yields lots of pages containing hacker- level instructions (e.g. adb commands) -- still no idea how this process was envisioned to work for average end-users.
