Just after creating the new Android Application Project, I get the error "R cannot be resolved to a variable" in my MainActivity.java file
Why am I getting this problem if the app was created by Eclipse choosing all the default options? How can I fix this issue?

I've got a project I'm learning with to test connecting to the flickr api and simply displaying recent images. I'm at the point now where I want to parse the JSON received from flickr. I've downloaded gson 1.4 and added the zip to the java build path through "add external jars." It's successfully loaded and I can see google-gson under referenced libraries in the package explorer. My problem is, when I try to use it, I simply get an error.
Gson gson = new Gson();
It highlights Gson and says that "Gson cannot be resolved to a type." What am I missing here? It worked once and has since stopped. I've tried removing the jars, cleaning the project and re-adding the jars but it still doesn't work.
I keep getting this error... should I just make "id" a field?

I want to implement my own Tokenizer base on the file
"MultiAutoCompleteTextView.java",
but I encounter an error "com.android.internal.R cannot be resolved" when I try to
import "MultiAutoCompleteTextView.java" to my project.

I haven't research any solutions to resolve this problem.How to correct "com.android.internal.R.attr.autoCompleteTextViewStyle" my own attr?
Is 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?

View 1 Replies View RelatedI updated to 1.5 SDK pre, together with the ADT. I followed the instruction to select Android 1.5 as target by right clicking on the project, Preferences>Android. In this window there are 3 options, Android 1.1 Android 1.5 Google APIs
I selected Android 1.5 and Apply, clicked OK. Application compiled nicely.
If I go back to the same Preferences and select Android 1.1, Apply, I can no longer compile my application successfully. I get hundreds of the same error R cannot be resolved
Then I try to open this project in another computer that I have not updated the SDK yet. I get the same error. I'm trapped until the new SDK is out.

I am using android-sdk-windows-1.1_r1 as my android SDK,and didn update this from 1.0 instead i installed it freshly.
I guess there might be some problem with the SDK.
If I don't import R, I get "id cannot be resolved or is not a field" (R.id.mainanim); And if I import R, the id error is gone, but I get "main and mainanim cannot be resolved or is not a field". They're my xml files! Also here is ALL my code... maybe there is an error I didn't see?

Everything was working fine earlier. I then happened to add a new xml file to my layouts. now, one of my classes is giving an error when setContentView points to (R.layout.menu). Eclipse is telling me that R.layout.menu cannot be resolved. I can't figure out why; I have a layout called menu defined in my layout folder.

I'm having "The project cannot be built until build path errors are resolved" after each Project->clean in eclipse. I have two projects with one referencing another. The error appears in the project referencing the another one. When the error appears I go to the 'configure build path' and then remove and re-add the referenced project and then magically the build is done fine.

I've been following the View tutorials included in the android developer site. When testing hte HelloGallery view, I get this compile- time error.
I searched for this error on this group but is wasn't answered. Can anyone help.
The problem reference occurs in the imageAdapter class that is appended after the onCreate() method in the HelloGallery class:
CODE:...................
Strangely enough, when I insert this lines into the onCreate() method at the start of the package, there is no problem. It seems that the android.R class is not known.
When working on the Hello, Gallery tutorial/sample app, after following the instructions on the site, Eclipse reported that R.styleable cannot be resolved. What is the reason for this error, and how can it be fixed or worked around?
View 3 Replies View RelatedI would like to setup a boolean called dFlag in the main.class of my program and reference it in another class.
I already have it setup to work locally just hitting a snag on how to do it.
Code:
public class Main extends Activity {
boolean dFlag; ///Debug flag, true=enabled | false=disabled
}
public class Other extends Activity {
if(dFLag = true) {
///Output debug message
}
}
Or is there an easier way to do what I want without having to re-invent the wheel so to speak?

View 2 Replies View RelatedI am working to set a countdown timer. I have successfully (borrowed) a number picker (spinner) and set up the dialog box for the user to set the time. This is in a class called timepickactivity and the variables are hour and mins (R.id.hour and R.id.mins). I want to call the set values (R.id.hour and R.id.mins) from the dialog (timepickeractivity) to the actual countdown class (countdown) but I can't figure out how to get the values.

View 4 Replies View RelatedI have some xml files, and I keep them in raw folder. Now, the problem is that I have to use them with variable name according to my application condition. But I don't know how to fetch them. The main thing is that I am not getting that how to give the path of my xml file in application.
For example:
My file application.xml is stored in the raw folder and I have to access it with a variable name.
String xmlName= application.xml;
How can I fetch my xml through xmlName variable?
I'm trying to use a Condition Variable to control the execution sequence of two threads. I can create a Condition Variable in one thread and block on it. But I would like to be able to access it from another Thread and unblock it from that thread.. ? Blocked Thread i am planning to keep as GUI thread and it should update the messages which are sent by b/g thread on the screen during its block state and will be unblocked by b/g thread in the end by calling open(); method.
View 3 Replies View RelatedI have this code:
hubSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parentView,
View selectedItemView, int position, long id) {
final MediaPlayer mp2 = MediaPlayer.create(Textbox.this, R.raw.hero);
mp2.start(); } public void onNothingSelected(AdapterView<?> parentView) {
} } );
(The code basically runs when a new item is selected of a spinner and then plays a song, which later will be a variable based on what was picked, but I'm fine as it is for now). And I want to be able to use 'mp2' out of this public void, (I want a button which pauses it). How can I do this?
Anyone know of an audio player that will speed up the playback? It would be nice if it could keep the pitch the same but sped up is the goal. I used TCPMP on the Treo. This is great for listening to podcasts in a fraction of the time. Depending on the original audio, I can generally make everything out up to +25%.

View 4 Replies View RelatedI have noticed in my application(s) that after a call to Activity.finish() that the static variables that I declared in my classes still hold the values that they were changed to during the activity's life cycle. Upon the re-launch of the activity, the program does not re-instantiate the variables as declared or set them to the default java behavior. Is there something that I can do to cause this to happen, other than re-setting every static variable in my application?
View 3 Replies View RelatedI am doing an app related to football. I have a list view that will have various rows representing teams. In my custom array adapter I want to write some code that will present an icon for the team represented by the row. I have a drawable resource for each team (for instance for Indianapolis, Ind.png). In my code I can't refer to "R.drawable. Ind" because the Ind part is dynamic. That value would be in an array, like TeamArray[position]. As I expected, I certainly can't use R.drawable.TeamArray[position] because it won't even compile, it expects a literal name from the drawable folder. Is there a way to do this?
