Always got Latitude 0.0, longitude 0.0, altitude 10.0, when sending coordinates with the Location Controls tool.

To correct this bug (coming from the locals of your machine, simply add this line to your eclipse.ini file :

-Duser.language=en

Enjoy

When I was binding my Activity to a Service with a ServiceConnection, I did this, and always got this error:

bindService(new Intent(this, PlayerService.class), this.psc, Context.BIND_AUTO_CREATE);

To resolve that, I asked for more debug :

bindService(new Intent(this, PlayerService.class), this.psc, Context.BIND_DEBUG_UNBIND);

Then this error disappeared !

Seriously, what happened ? I have no idea, but I’m happy my application doesn’t crash anymore after the user just closed it…

No, I’m not.

First, I used PHP before falling in love with Ruby. Secondly, I’m just a simple user. Users don’t care about technologies, only about solutions, and this one works fine for me !

So I merged my “portfolio” and my previous blog, to one central place.

Hurray for the new site ! Hurray !

By default, ruby 1.8.7 came with my mac. But I could not update rubygems, I just got this error:

	  /usr/bin aren't both writable.

To resolve that, you have to install XCode. Right after this step, things are easier :

• sudo gem update
• sudo gem install rails –include-dependencies

That’s it !

So here’s how to block the application on the “Portrait” layout:

Set the attribute “screenOrientation” to the value “portrait” into your main Activity in AndroidManifest.xml:

<activity android:name=".activities.OxydroidActivity"
    android:label="@string/app_name"
    android:screenOrientation="portrait">
</activity>

Thanks to Evan JIANG !

Here is the code to add something like in this image : a dialog (pop-up) with buttons in Android.

Normally, the user may come back to your application with the “back” button. I wanted it to be a dead-end dialog. My aim was to close the application if there is no Internet connexion at all.

In this example, I set a modal AlertDialog with a title, a message, and an “OK” button, which will close the application (my current activity and a service).

What makes it modal, which means the user can not go back to the application without pushing the “OK” button, is the setCancelable(boolean) function.

AlertDialog alertDialog = new AlertDialog.Builder(this).create();
alertDialog.setTitle("No connection");
alertDialog.setMessage("Oxydroid a besoin d'une connexion à Internet. Veuillez vérifier vos paramètres.");
alertDialog.setCancelable(false);
alertDialog.setButton("OK",new OnClickListener() {
	public void onClick(DialogInterface dialog, int which) {
		stopService(new Intent(Oxydroid.this, PlayerService.class));
		Oxydroid.this.finish();
	}
});
alertDialog.show();

Here’s how to compare:

• Get the encrypted_password
• Get the not_encrypted_password
• Compare the passwords by encoding the not_encrypted_password using the two first characters of the encrypted_password as salt for the crypt method.

In Ruby language, this means coding something like this:

not_encrypted_password.crypt(encrypted_password[0,2]) == encrypted_password

return true if passwords are maching. Youpi !

I did this article to never forget this… Hoping it would be helpful for someone else !
