ワイヤレス接続が利用可能になると、FTP サーバーにデータをアップロードするアプリに取り組んでいます。問題は、デバッグ モードの場合にのみデータがアップロードされることです。
if (sharedpreferences.getBoolean("autoupload",false)){
// Do your work.
String directory = context.getFilesDir().getAbsolutePath() + File.separator + "Messdaten";
File f = new File(directory);
File[] files = f.listFiles();
if (files.length != 0 ){
for (int i = 0; i < files.length; i++) {
String filepath = files[i].toString();
FTPupload FTPu = new FTPupload(filepath);
FTPu.execute();
Toast.makeText(context, "BikeLog Daten werden hochgeladen", Toast.LENGTH_SHORT).show();
}
}
}
トースト メッセージが表示されるので、他のすべてにも到達するはずです。しかし、デバイス エクスプローラーでデータを確認すると、アップロード後に削除する必要がありますが、まだそこにあります。
class FTPupload extends AsyncTask<Void, Void, String> {
String path;
ProgressDialog uploading;
public FTPupload(String filepath) {
path = filepath;
}
@Override
protected String doInBackground(Void... params) {
FTPSClient con = null;
try {
con = new FTPSClient();
con.connect("XXXXXXXX");
if (con.login("XXXXXXXXXX", "XXXXXXXXXXX")) {
con.enterLocalPassiveMode(); // important!
con.setFileType(FTP.BINARY_FILE_TYPE);
FileInputStream in = new FileInputStream(new File(path));
String filename = path.substring(path.lastIndexOf("/") + 1);
boolean result = con.storeFile(filename, in);
in.close();
if (result) {
Log.v("upload result", "succeeded");
File file = new File(path);
boolean deleted = file.delete();
}
con.logout();
con.disconnect();
}
} catch (Exception e) {
e.printStackTrace();
}
return path;
}
}
クレイジーなことに、コンピューターに接続して FTP 接続にブレークポイントを設定すると、すべてが計画どおりに機能し、データがサーバーに送信されます。
何が間違っているのかを理解するのを手伝ってもらえますか? どんなヒントでもいいです！
