In the layout editor in Eclipse, I have created a custom view. For some reason, there are a few methods which cause NoSuchMethodError exceptions in the code. Here is the code in the initializer of the custom view:.............

System config is MacOSX with default JDK 1.5.0_16. Eclipse 3.4 The problem is I have a project in workspace that has been developed under JDK 1.6.I don't really want to switch back to 1.5 ( i' would have to clean up a LOT of @Override ) but if i work with this project, after couple of rebuilds - eclipse layout editor not able to display preview. Work around i found so far open android project that is in compliance with Java 1.5. Close everything else and rebuild workspace. But it's kind of annoying to do it every time.

View 3 Replies View RelatedI'm porting an app of mine to work better with API 1.5, and I'm having problems with the layout files where I'm using an AutoCompleteTextView (and, naturally, MultiAutoCompleteTextView). Whenever I have them present in a layout, the graphical representation of the layout disappears, and "NullPointerException: null" replaces it. Is there any way I can view a widget such as this in the Eclipse editor? It definitely worked in the 1.1 SDK, otherwise I wouldn't have used them.
View 2 Replies View RelatedIs there a (simple) way to completely and utterly disable all Java formatting in the Eclipse editor?
That is an Eclipse question, but I appreciate your indulgence because this problem is slowly driving me insane. I am spending a lot of time fixing code to make it look good again after it gets mangled by the automatic formatting. I thought I had removed all formatting keyboard shortcuts, but I missed something because my code keeps getting changed. I suspect the culprit to be the SourceFormat menu option because that can be triggered by Alt-S-F which is very close to Alt-F- S, the File/Save command.
So a little finger slip and code mangled. Unfortunately, the mangling is not always done where I am looking (since it is applied to the entire file), so I don't always know to undo it. Is it possible to disable or remove a menu item?
This is probably related to this question. I want to know if anyone else gets the same error as me and if there is a way to get around this. I did the following: Followed the instructions from this page. From the top, go to File -> Create a new project -> Android Project -> Create project from existing sample. Checked Android 2.2. From the drop-down menu picked SkeletonApp. Clicked finish. From the package explorer, went to SkeletonActivity -> res -> layout -> skeleton_activity.xml. In the tabs at the bottom of the editor area (editor area is the center of the screen) clicked on Layout. Then I got the error "ClassCastException: android.widget.EditText cannot be cast to andoid.text.ViewGroup". The full text of the error message is given below.

I'm new to Android & Eclipse. I've downloaded Eclipse and the Android ADT and created an ultra-simple "Hello World" app (has only auto-generated .java and .xml files). Eclipse CRASHES (closes after a very brief pause) when I do the following: In Package Explorer, select AppName/res/layout/main.xml Press, or double-click, or 'Open With' then 'Android Layout Editor' (The app runs OK in the Android emulator) My configuration is:
Android Development Tools 0.9.5.v200911191123-20404 com.android.ide.eclipse.adt.feature.group
Eclipse IDE for Java Developers 1.2.2.20100216-1730 epp.package.java
Windows XP
Can someone tell me what I'm doing wrong or what's wrong with my configuration? Any suggestions on what to check? For any non-trivial app development I need to be able to use the Layout Editor. More ... I can select main.xml and Right-Click and 'Open With' any of: XML Editor, XML Schema Editor, Text Editor -- with no problem. The problem is limited to Android Layout Editor.
Has anyone figured out how to scroll the contents of the Layout Editor when those contents overflow one "screen"? I'm talking about at design-time while using the ADT Layout Editor, not scrolling at run-time on a physical device (that works fine).
View 2 Replies View Related1. Can I call ADT Layout Editor in my java source file, not by XML file "open with" menu ?
2. When I click "add" button in the outline view of ADT Layout Editor , it will show such a list of UI components as "AbsoluteLayout AnalogClock AutoCompleteTextView Button ....." My question is where it gets this list? Can I config this path to get my customized UI components?
Why there is difference between the screen layout in eclipse in xml editor and in the emulator?

Maybe it is not an Eclipse problem but an problem of my project setup.

I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

View 2 Replies View RelatedI thought ADT should come with a visual editor for building GUI : http://stackoverflow.com/questions/851882/easy-way-to-build-android-ui However, I just cannot find it. I was wondering where is the Visual Editor for Eclipse with the ADT plugin. I can run HelloWorld application without problem. However, whenever I click on main.xml at the left navigation tree layout folder, here is what I get. What I wish to get is a WYSIWYG editor.
View 4 Replies View RelatedIs there an explanation of the ADT layout editor UI some place? I can't find anything on the Android web site about it. When I look at a layout in the design view, there are a number of fields at the top with labels like MCC, MNC, Lang, etc. I've noticed that I can change the contents of these fields, such as orientation, and it has an effect on the view. But a yellow warning triangle appears next to the field I've changed and the next time I open this view I see the unmodified field. For example, if I change to landscape orientation the view goes back to default next time. Is there documentation some place on what these fields mean and how they are supposed to be used?

I have an app that runs perfect on 2.2 and 2.2 but always getting VerifyError on 1.6 while startup, I don't think that my app cannot run under 1.6 because I don't call any APIs that don't support 1.6. I'm really confused, does anybody has the same issue?

I'm trying to add ScoreNinja, the global high score system, to my Android game, and it works fine when I load it on my phone, but when I release it into the wild, I got crash reports saying: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
Here is part of the call stack:
android.os.Handler.<init>(Handler.java:121)
android.app.Dialog.<init>(Dialog.java:99)

I thought the main thread had prepare() called automatically, and if not, why would it work fine for me but not anyone else?
I've got a strange problem here doing object de/serialization. In Java (JDK 1.6) I serialize some objects. In Android (SDK 1.1) I deserialize them. This work quite nice in general. In order to work with a server object (that uses Castor un/ marshalling) I do it like I always do. Same routines. Well, this time the file is only 172kb (my routines works pretty well with 2,4mb files) but the interlacing is quite deep. So it all starts with a class containing 2 ArrayLists. I tried de/serializing just ArrayList<String> and this works very well. But the XML file (which is unmarshalled with Castor and serialized in JDK) has 7000 lines. So I get this StackOverflowError....................
View 3 Replies View RelatedI'm getting this error: "Uncaught handler: thread main exiting due to uncaught exception java.lang.VerifyError" It's only happening on 1.6. Android 2.0 and up doesn't have any problems, but that's the main point of all. Can't catch the Error/Exception (VerifyError), and I know it's being caused by calling isInitialStickyBroadcast() which is not available in SDK 4, that's why it's wrapped in the SDK check. I just need this BroadcastReceiver to work on 2.0+ and not break in 1.6, it's an app in the market, the UNDOCK feature is needed for users on 2.0+ but obviously not in 1.6 but there is a fairly amount of users still on 1.6.
private BroadcastReceiver mUndockedReceiver = new BroadcastReceiver()
{
@Override
public void onReceive(Context context, Intent intent)
{
//FROM ECLAIR FORWARD, BEFORE DONUT THIS INTENT WAS NOT IMPLEMENTED
if (Build.VERSION.SDK_INT >= 5)
{
if (!isInitialStickyBroadcast()) {
int dockState = intent.getExtras().getInt("android.intent.extra.DOCK_STATE", 1);
if (dockState == 0)
{
finish();
}
}
}
}
};
I am trying to save the date of file parsing, so that when next time user, opens the application, the date can be checked against the last parsing date. I am using shared preference to save the data and retrieve it, but getting error. here is the code:

String today = new Date(System.currentTimeMillis()).toString();
SharedPreferences.Editor edit = settings.edit();
System.out.println("******** Today : " + today);
edit.putString("lastdate", today);
String fetch = settings.getString("lastdate", "0");
System.out.println("******** Fetch : " + fetch);
txtTest.setText(fetch);
but I am getting null pointer error. am I missing something?
I'm facing a recurrent problem that I don't know why it is happening. It happens all of a sudden. I didn't do anything different from what I was doing before. I'm using these tabs: http://developer.android.com/resources/tutorials/views/hello-tabwidget.html. When I open one of the three tabs (Class name = Tab1), this problem comes out. Before, this error came out after clicking all of the tabs.
A part of the stack trace: Could not find class 'org.android.catsMobile.packageName.Tab1$OrderAdapter', refereced from method org.android.catsMobile.packageName.Tab1.onCreate [...] threadid=3: thread exiting with uncaught exception (group=0x4000fe70) java.lang.VerifyError: org.android.catsMobile.packageName.Tab1.
I have one android project. I have one class file of about 6000 lines when i tried to add more code it shows the java.lang.verifyerror.
