前回の投稿のコードではisReacheableの挙動が変（いつもfalseとかtrueとか）になって、実用時に問題が起きたのでHttpでチェックするコードを書きました。実行速度的にはイマイチですがまあしかたないです。

private static boolean checkNetworkByHttp() {

BufferedReader br = null;

boolean result = false;

URL rssurl = null;

try {

rssurl = new URL(”http://どこかIPで指定した方が早いかも”);

br = new BufferedReader(new InputStreamReader(rssurl.openStream(),

“UTF-8″));

String buf = “”;

while ((buf = br.readLine()) != null) {

result = true;

break;

};

} catch (Exception e) {

} finally {

if (br != null)

try {

br.close();

} catch (IOException e) {

}

}

return result;

}

//外に出れたらtrue

public static boolean checkNetwork(Context ctx) {

ConnectivityManager cm = (ConnectivityManager) ctx

.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo ni = cm.getActiveNetworkInfo();

if (ni != null) {

if (!cm.getActiveNetworkInfo().isConnected()) {

return false;

}

} else {

return false;

}

String addressText = “www.google.com”; //ここは自社サイトとかにしましょう

InetAddress address;

try {

address = InetAddress.getByName(addressText);

return address.isReachable(2000);

} catch (UnknownHostException e) {

return false;

} catch (Exception e) {

return false;

}

}

if (status.equals(Environment.MEDIA_MOUNTED)) {
try {
File path = Environment.getExternalStorageDirectory();
StatFs stat = new StatFs(path.getPath());
long blockSize = stat.getBlockSize();
long totalBlocks = stat.getBlockCount();
long availableBlocks = stat.getAvailableBlocks();

// free/total memory in the SD card
tvFlashCardCapacity.setText(”SD card: ”
+ formatMemorySize(availableBlocks * blockSize) + ” / ”
+ formatMemorySize(totalBlocks * blockSize));
} catch (IllegalArgumentException e) {
// this can occur if the SD card is removed, but we haven’t
// received the
// ACTION_MEDIA_REMOVED Intent yet.
status = Environment.MEDIA_REMOVED;
}
} else {
tvFlashCardCapacity.setText(”SD card: unavailable”);
}

File path = Environment.getDataDirectory();
StatFs stat = new StatFs(path.getPath());
long blockSize = stat.getBlockSize();
long totalBlocks = stat.getBlockCount();
long availableBlocks = stat.getAvailableBlocks();

// free/total memory in the internal memory
tvInternalMemoryCapacity.setText(”Internal memory: ”
+ formatMemorySize(availableBlocks * blockSize) + ” / ”
+ formatMemorySize(totalBlocks * blockSize));
}

思い当たる節はSDKを2.0対応にしたこと・・・ま、まさか！

確かに2.0にしてからサインしたことなかったよなと思いながら、とりあえずEclipsを再起動したり、Windowsを再起動したりしましたがだめです。

キーファイルの破損も疑ったのですが、別の1.5r3から上げていない環境でコンパイル＆サインができたのでとりあえず一安心。

さらに別の2.0環境ではちゃんとサインできることも確認。てことはこいつだけなんかおかしくなってること確定。
一番最初から使ってたからJREのバージョンとかが2.0SDKのお気に召さなかったのかなと思って、JREを最新に上げて再トライ・・・だめです。じゃあADK&SDKを再インストール・・・だめです。おいおい！！

んーと困ったあげく、”いいや、Eclips入れ直しても１５分だし。”ということでEclipsから入れ直しました。
当然（？）ちゃんとサインできるようになりました。

念のため（？？）元のEclipsでサインしてみると・・・やっぱりだめです。
’やっぱなんかよれてるんだな。よしよし。今度の勉強会でネタにしよう。’と思った刹那、ふと’eclipse.exe -clean.cmdしたらどうなんだろ？’という考えが頭をよぎりました。
：
やってみました・・・動きました、サイン。

 今日の教訓： Eclipsが変な挙動をしたら、まずeclipse.exe -clean.cmd！あわててEclips入れ直したりJavaをバージョンアップしない。おちつけ自分。

AsyncTaskがまともに動作するようになった。困った。
1.6だと同時実行数が５個までに増加した（1,5は１個！）。それ以上は1.5同様キューイングされる。

SDK1.6よりよりSDカード書き込みのパーミッションが必要
<uses-permission android:name=“android.permission.WRITE_EXTERNAL_STORAGE”/>

そんなときは（手前味噌ですが）Adownというアプリを使ってみてください。

このアプリは動画や音楽、画像、HTMLページなどをダウンロードできるアプリです。

使い方は簡単です。ソースコードを見たいページをブラウザで開き、メニューからページを共有とするだけです。
するとAdownがそのページをダウンロードしてくれるので、あとはそのファイルをFileViewerとかで見ればOK.
cssとか画像は一緒にダウンロードしないのは仕様です（すみません）。

このアプリのコメントや要望は

までよろしくお願いします。

ダウンロードはマーケットからどうぞ！
