HttpHostConnectExceptionユーザーがインターネットに接続せずにデータを送信しようとしたときに処理したい。サーバーに接続する RestClient クラスで次のようにします。
catch (HttpHostConnectException e) {
client.getConnectionManager().shutdown();
try {
throw new NoInternetException();
} catch (NoInternetException e1) {
inetError = true;
e1.printStackTrace();
}
e.printStackTrace();
}
例外をキャッチしたときのアクティビティで：
catch(NoInternetException e) {
this.cancel(true);
editor.clear();
editor.commit();
finish();
startActivity(getIntent());
Toast.makeText(LoginActivity.this, "You've lost internet connection. You should try later.",Toast.LENGTH_LONG)
.show();
e.printStackTrace();
}
この例外を処理し、ユーザーが最後に使用した現在のアクティビティを再起動し、「接続がありません」などのトーストを表示したいと考えています。しかし、強制終了ボタンで例外ポップアップが表示されます。表示したくありませんが、アクティビティをリロードして、メッセージでトーストを表示したいです。どうすればこれを実装できますか?
