Android of mucchin Senki

Felt about the appeal to self-introduction and Android

I currently have a SE of software application system Web.

Was an opportunity that was asked that I learned of the existence Android (Android) I started, the company's sales now, "I work seems to have mobile app called Android,? Or interesting" and.

I, by the company before now, so the PG which had been built-in mobile phone, and business, if I would know, I have been listening.

But, at that time I did not know quite what that Android.

Much, but Hashori, I thought that was examined, the presence or become a competitor of iPhone!

I thought.

So, maybe I should try to study and application of the iPhone, Android, either?

Was considered.

Variously thought, I thought from the following points, trying to study for Android.

Android, unlike the iPhone, there is a possibility of Android OS smartphones will be released from many manufacturers!

To that point, I was attracted.

iPhone does not come out only from the company Apple · · ·.

After simple calculation was, as a number should be higher than Android!

Android application development is done in Java.

I (self-styled) good at Java.

app on the iPhone, Objective C · ·?

Well transient.

To publish your app, Google have to pay about $ 25 registration fee, can register to the Android Market almost without examination.

This is also attractive.

The registration of paid apps can also commission is likely to be taken 30%, as a sideline or not it Now!

So, I started to study the development of Android apps.

Have to study for Android, and I Na was also easy, but difficult Mecha!

There are some places I thought, this site, and for its own memorandum, posted as they are about to go, etc. The solution to the problem that I ran.

How to resolve the Debug certificate expired on ...: Error generating final archive

Suddenly one day: how to resolve the error message "Error generating final archive Debug certificate expired on ..." is displayed, you can no longer compile the Android app?

Everyone, suddenly appears out the above error message, can suddenly no longer compile Android app! How will that experience there is.
I thought let's try to even an extra feature of the Android application he had made, launching the Eclipse a long time fine, if you try to compile the app, was no longer possible to compile out the above error message suddenly It was insanely impatience.

If you look, as a result, this experience is that it was years have elapsed since a happily begun studying Android, but is a happy event a sense, if you can not resolve, can not compile Android app So, I'll a problem.
In this case, I would like to introduce you how to deal with the above error occurs.

I think that if you read the error message calmly, that the certificate has expired or is some kind of imagination who can also be folded.
That's right, has expired and the certificate of some kind, this error has come out.
I called that something is a file in the directory below.
Directory: C:. \ Documents and Settings \ \ (Windows user name) android
File: debug.keystore
(I think if Windows XP, but located in the directory above, if Windows 7 and Vista, and how to be a little different directory to be precise.)

The solution is simple.
It just removes the debug.keystore above.

Then, just to be sure, a good idea to recompile the whole project is.
The simplest procedure is OK the following procedure be carried out using the Eclipse.
Is OK in the> "Clean" - menu -> "Project".
Something like the following is to explain the image.
