Hy !!ProgressDialogが見えない
プログレス・ダイアグラムに問題があります。
私の使用コード：

finish();
}
else

}
}

Toast toast ;
toast = Toast.makeText(getApplicationContext(), e.getMessage(), 500);
toast.show();
}
}
private String md5(String in) {
MessageDigest digest;
try {
digest = MessageDigest.getInstance("MD5");
digest.reset();
digest.update(in.getBytes());
byte[] a = digest.digest();
int len = a.length;
StringBuilder sb = new StringBuilder(len << 1);
for (int i = 0; i < len; i++) {
sb.append(Character.forDigit((a[i] & 0xf0) >> 4, 16));
sb.append(Character.forDigit(a[i] & 0x0f, 16));
}
return sb.toString();
} catch (NoSuchAlgorithmException e) { e.printStackTrace(); }
return null;
}
}
エラーなしでのDalvikデバッグモニタで発生します。
私はこのような場合のためにAsyncTaskを使用することをお勧めします
