Why do I get java.lang.ClassCastException when I tried to cast back an array of custom object that implements Parcelable?
Here is the custom class:

I am writing a adapter for a specific app, the problem I met is:
I have only 1 listview in main.xml, and the row style is defined in file_row.xml. If I simply use list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); where items is a ArrayList<String>, everything works well.
But if I use my custom Adapter, say, list.setAdapter(new MyOwnListAdapter(this, filename)); and in the class of MyOwnListAdapter, the code has been simplified as
CODE:................
But I always met the problem which is:
CODE:.........
I thought the self-defined Adapter class actually has only one line of valid execution, which is super(context, R.layout.file_row, R.id.file_name, filename_list); It's essentially identical to direct calling of list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); Then why I always got this error if I call my own Adapter?
I've run into an early problem with developing for android. I've made my own custom View (which works well). In the beginning i just added it to the layout programmatically, but i figured i could try putting it into the XML layout instead (for consistency).
So what i got is this:
main.xml:
CODE:..........
(Theres obviously more, but you get the point)
Now, this is the stacktrace:
CODE:...........
Why cant i cast my custom view? I need it to be that type since it has a few extra methods in it that i want to access. Should i restructure it and have another class handle the logic, and then just having the view being a view? I'd really like this to work though.
Java packages like Java.io, Java.Lang etc used in android, are they different from Java packages in windows ? means specially made for android ?
View 2 Replies View RelatedI'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. 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; ....

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?
View 18 Replies View RelatedI have the following code which gets call in my main activity's onCreate method
public static ErrorReporter getInstance(){
if (instance == null){
instance = new ErrorReporter();
}
return instance;
}
Only on android 1.5 calling the above method causes java.lang.VerifyError. I am not able to figure out why this is happening.
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)
android.app.AlertDialog.<init>(AlertDialog.java:65)
android.app.AlertDialog.<init>(AlertDialog.java:61)....
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:
SharedPreferences settings = getPreferences(0);
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.

I am using custom listadapter for ListActivity, but half adapter is getting built and then throws "java.lang.StackOverflowError". When I ran the same code on sdk1_1r1 it works perfect. When do i try to run on sdk1_5r3, gives this error. Generally java.lang.StackOverflowError when happens if the some function caught in infinite recursion, but if this is case then why does it working on sdk1.1r1 perfectly. I tested the appl on sdk1_5r3 both emulators default AVD(96 RAM) and custom AVD(523 RAM). For all try it gives the same error.

The icon for the program is present in my emulator, and I have added android.permission.ACCESS_CHECKIN_PROPERTIES to my Manifest.

I'm getting this crazy error on multiple projects, even when I revert back to prior versions that compiled just fine. Unknown Error - java.lang.NullPointerException Android Packaging Problem Path is blank Location is Unknown. 1 - Project -> Clean -> All 2 - Deleting .metadata folder 3 - reimporting projects into the eclipse 4 - reverting my projects back to prior working versions using git. I just can't get anything to compile now, and I've searched for solutions here and on eclipse forums.
