    Hi, I've got keytool sitting in the jdk, and it works when I use
    eclipse to automatically sign an application package. However, I'm
    struggling to run keytool to get an MD5 Fingerprint. When I go to the
    jdk bin folder and try to run keytool, a command prompt window opens
    and then closes after a second. It's probably something really simple
    I'm missing. Could I have some help please? I'm using Windows.

    Open a command prompt window, and run the keytool command
    (with appropriate parameters) from there. It's a command line utility,
    so if you just double-click it, it will display a usage message and
    exit, closing the command prompt window.

    you're probably using network location which gives you the illusion of a
    quicker GPS fix. Switch that off, then start the camera app, and see how
    long it takes to get a real GPS fix. We're talking tens of seconds here.

    Hi James,
    I think I have fixed the problem. The following may answer your
    In the onCreate() in my ContentProvider, I was leaving the database
    public boolean onCreate()
    UKMPGDataProvider.init(getContext(), Constants.DATABASE_NAME);
    return (UKMPGDataProvider.getWritableDatabase() == null) ? false :
    (In my defence, this was copied from a tutorial on the net.)
    In my test, the addVehicle() would result in a call the
    getWriteableDatabase() on SQLiteOpenHelper, which looks like this
    (shortened for clarity):
    public synchronized SQLiteDatabase getWritableDatabase() {
    if (mDatabase != null && mDatabase.isOpen() && !
    mDatabase.isReadOnly()) {
    return mDatabase; // The database is already open for
    //lots more initialisation here, omitted
    int version = db.getVersion();
    if (version != mNewVersion) {
    try {
    if (version == 0) {
    } else {
    onUpgrade(db, version, mNewVersion);
    } finally {
    //omitted code again
    As I had left the database open, execution would not get passed the
    first if statement and the onCreate(db) line would never be reached.
    In my code, I would close the database after inserting a vehicle, so
    next call to getWriteableDatabase() (getVehicles()) would get passed
    the first if statement and execute the onCreate(db).
    It doesn't really explain why the first insertion was successful
    though. And it doesn't explain why the test passed in 'run' mode. I
    added some logging to the onCreate() in my ContentProvider and
    SQLiteOpenHelper and in run mode the ContentProvider onCreate() is
    called twice.
    I don't know if this made the difference or not... If anyone can shed
    any light on what the difference is between run and debug when unit
    testing, I'd be interested to learn more.

    OK, OK, I shall look at it. May be it can simplify some of my tasks.
    You see there are always so many things to look into it that ends up
    looking a few things only.
    Java alone has so large a library it will probably take quite a while to
    get acquited with them, or at least read them very quickly just leave an

    I have done some pretty simple socket programing with C/C++. In this case,
    with pointers I have quite a free hand to encode my data using a scheme
    onto a memory buffer. At the receiving end once I get socket data into a
    memory buffer I can easily decode the data.
    As of now, I am just not certain how to encode my data onto a bytearray
    with java tools. For example given an integer, with C, just obtain a
    pointer to the integer then pack the 4 bytes one by one onto my buffer. In
    java, I think, as of now, I have to use the 'shift' operator and be
    careful with the sign bit.
    For you info, the file I/O and byte stream features in java are
    bewildering to a new comer. For one with a lot time they are no much of a
    problem. Thus advice help of gurus are essential to cut down learning time.

    What do you mean it "asks you to typecast 'this' " ?
    What is "this"?
    Is it an OnGroupClickListener?

    Posting the crash would help.

    I mean Eclipse suggests that as a fix.
    There is an example for using the onChildClick and in onCreate the
    line getExpandableListView().setOnChildClickListener(this); is
    included so if I want to also have onGroup click I assumed that I need
    getExpandableListView().setOnGroupClickListener(this); but that causes
    an error the suggestion in Eclipse is to change it to
    I am after any item click if there is another way, the code that I
    want to run onClick is the same for Group or Child. I can see in the
    parent class there is an event but I don't know how to use it, I am
    new to this.
    Thanks again

    OK. Then read this whole thing and try again:
    You still didn't explain what "starched" means and I, for one, have no idea
    what you're getting at.

    proguard is some type of 3rd party file for version checking or
    I normally ignore them or just delete them.


    al <achim.leubner@googlemail.com> Dec 31 01:20AM -0800  

    Proguard is a tool to shrink and obfuscate apps. For details, see
    http://proguard.sourceforge.net/#FAQ.html . The proguard documentation
    is very good. You might want to take a look.

    Maybe it's a 4.0.2 vs 4.0.3 problem. You could try it in an emulator
    and if it's a regression in 4.0.3, create a bug report.

    I'd say so.

    How about using publishProgress() and onProgressUpdate() to notify the
    user? You may already be using it to keep the user updated to the progress
    of the download, but seems to me you could use it to let them know about
    post-download processing too.

    I guess you gave the obvious answer yourself: Don't hardcode the name.
    Use a variable, maybe a system setting or something from a config file
    that can be accessed by all your apps and put an if/else block in your
