Android :: Loading String Values From File Instead Of List In Class
Nov 1, 2010I think I have a pretty easy problem to solve, but I have been beating my head against the wall for hours trying to get past it! I have an adapter that loads a list of URLS:
adapter=new MyAdapter(this, lStrings);
list.setAdapter(adapter);
The list of URLS looks like this:
private String[] lStrings={
"http://www.domain.com/file1.jpg",
"http://www.domain.com/file2.jpg",
"http://www.domain.com/file3.jpg",
};
What I want instead is to load these values from a text file that lies on the SD card. For that matter, I would be okay with loading the values from a text file into a String, and then load the String into the list as I imagine that would be the "cleaner approach". However, all attempts to do this have failed. For instance, I replaced the above snippet with this:
private String[] lStrings=
{ MainActivity.this.getString(R.string.myurllist) };
but then I get a Forced Close on loading.
I'm a bit new to Java, Android, and development in general.
Android :: Loading Layout From XML Inside Of Derived Class
Mar 4, 2010Right now I have a class that extends LinearLayout and builds the view inside of the constructor using a series of addViews. I wanted to move this into an XML file, so I have the same view defined there. My problem is that I can't figure out how to load the XML file in the constructor of the derived class. I looked up the LayoutInflater stuff, but I wasn't entirely sure how to use it in that context. Do I need to call addView() with the result of the LayoutInflater? Is this even possible? The other issue is that the context object that is passed in doesn't have the LayoutInflater methods. I'm not sure if I need an instance of Activity to do that.

Aug 20, 2010I would like to make a single Android app for multiple Android versions (possibly every one of them)
My problem is that I want to check what is the version of Android the app is currently running on, and dynamically load a class which is version dependent. This part should be ok.
I just wonder how I can achieve that without compilation errors in my Eclipse project. I mean, the project is configured for a particular target (1.5, 2.1 ...), so if a class in my project is not compatible wich the selected target, it will result in errors.
Is there a way to export this classes even if they are not fit for the platform (I thought about a separated lib, but then again : how to compile theses classes into a lib without compilation pbs?) ? This should be ok since they won't be loaded until I ask them to after having checked Android version.
Android :: Does The Dalvik File Format - .dx - Support More Instructions Than Java .class File
Apr 17, 2010Is 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 :: Class Initialization Issues Loading Java.util.logging.LogManager In Dalvik VM
Mar 18, 2010I've done changes in an Android native library and installed a new system.img file but am now getting an unrelated Error on startup. I can get past it by swallowing the error but I wanted to know if anyone can explain what the issue is.
The Android implementation of Logger.java claims that it is Forcing the LogManager to be initialized since its class init code performs necessary one-time setup. But this forced initialization results in a NoClassDefFoundError. I'm thinking that it has something to do with the class not having been preloaded by Zygote yet but am not that familiar with the whole class loaders and VM business.

Android :: Loading From Compiled XML File
Jun 30, 2010I have some xml files with a custom format (based on the scxml specifications) that I want my program to read. I've already written the code to read it, but I'm running into problems actually reading the file itself. I want the file to be compiled with the apk, as it will not be changed at all during run time. So I put the file (test.xml) in the res/xml/ folder, and got the inputstream by using:
getResources().openRawResource(R.xml.test);
But when I read in this inputstream it is complete jibberish, which makes me suspect it is being read in binary, as openRawResource() is often used for binary files like images, if I am correct. What is the correct way to do this?

Android :: Loading APK File On Device For QA / Testing
Sep 7, 2010I'd love to get some ideas on best practices for testing our Android software, especially for AT&T devices. We're using a Samsung Captivate, on AT&T. As you know, AT&T disables sideloading (no Unknowns Sources option in Settings->Applications). We need to have our QA team load our apk file onto these devices as part of our testing and validation process. We're willing to install the SDK if needed, and upload the apk file via USB. We are not willing to root the phone.

Android :: Dynamic Loading Of Complete Layout File
Jul 1, 2010I'm dealing with a problem you guys might not have faced earlier. I'm having a use-case in my Android application where the actual screen that I want to show to user is not stored in any layout file of my application. The layout of the of the screen is designed by server in this case, based on selection made by user on first screen.
Let me elaborate here,
1st Screen : List of check box with different biller names. (Imagine I've selected 2 billers from this screen)
2nd Screen : (The screen that server has decided how it should look like)
* Header,
* 1st Biller name (Label)
* Amount for 1st Biller TextBox
* Image (a Separator image)
* 2st Biller name (Label)
* Amount for 2st Biller TextBox.
* Here there can be a checbox/radio/another TextBox anything.
* Image (a Separator image)
* Button (to submit above form back to server)
I hope makes some sense in what I'm planning to design. The current issues I'm dealing with are as below.
1). How to draw this dynamic widgets?
2). How to fetch user Inputs from this dynamically created widgets?

Android :: Eclipse Class File Metadata
Jun 7, 2010In Visual Studio, I can obtain a succinct list of public methods/members exposed in a class for which I do not have the source (i.e. bundled inside a DLL) by pressing F12 (GoToDefinition).
Similarly, I am learning the Android API - in Eclipse. Jumping to an Android framework method definition produces decompilation output which is not intuitive to read, and is very verbose. To mimic results like Visual Studio, I am considering several options:
How can I format the decompilation output to be 'cleaner' - I have looked through Eclipse's preferences menus and have not found a way to do this.
How do I 'add corresponding source files' once Google provides it, so that jumping to definition yields the actual definition?
Is there a plugin that does this already? I looked into Jadclipse, but that project has not been updated in several years, and is still a decompiler.

Android :: Multiple Versions Of Same Class File For Different SDK Targets?
Nov 5, 2009This is for an Android application but I'm broadening the question to Java as I don't know how this is usually implemented. Assuming you have a project that targets a specific SDK version. A new release of the SDK is backward incompatible and requires changing three lines in one class. How is this managed in Java without duplicating any code(or by duplicating the least amount)?
I don't want to create two projects for only 3 lines that are different. What I'm trying to achieve in the end is a single executable that'll work for both versions. In C/C++, you'd have a #define based on the version. How do I achieve the same thing in Java?
