我的错误
05-22 21:22:41.615: WARN/DownloadManager(262): Aborting request for download 15: http error 416
这是我的onCreate代码
super.onCreate(savedInstanceState);
//cek koneksi internet
cd = new ConnectionDetector(this);
IsConnected = cd.isConnectingToInternet();
Bundle b = getIntent().getExtras();
konteksCocok = b.getString("kts_cocok");
Log.d("konteks datang", "data: " + konteksCocok);
if(IsConnected) {
new downloadFile().execute(urlBerkas);
} else {
showAlertDialog(this, "Koneksi Gagal", "Tidak ada koneksi internet", false);
}
这是我的json和下载管理器代码
class downloadFile extends AsyncTask<String, String, String> {
int count;
@Override
protected void onPreExecute() {
super.onPreExecute();
progress = new ProgressDialog(unduhBerkas.this);
progress.setMessage("Mengambil data...");
progress.setIndeterminate(false);
progress.setCancelable(false);
progress.show();
}
@Override
protected String doInBackground(String... xUrl) {
// TODO Auto-generated method stub
//mendapatkan data dari database berupa detail berkas
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("konteks", konteksCocok));
Log.d("konteks kirim", "data: " + konteksCocok);
JSONObject json = jParser.makeHttpRequest(url_webservice, "POST", params);
Log.d("data: ", json.toString());
//menampilkan data lokasi POI
try {
int sukses = json.getInt(TAG_SUCCESS);
if(sukses == 1) {
POI = json.getJSONArray(TAG_BERKAS);
for(int i = 0; i < POI.length(); i++) {
JSONObject c = POI.getJSONObject(i);
nama = c.getString(TAG_NAMA_PENGGUNA);
konteks = c.getString(TAG_KONTEKS_BERKAS);
urlBerkas = c.getString(TAG_URL_BERKAS);
namaBerkas = c.getString(TAG_NAMA_BERKAS);
Log.d("namaDB", "data: " + nama);
Log.d("ktsDB", "data: " + konteks);
Log.d("urlDB", "data: " + urlBerkas);
Log.d("berkasDB", "data: " + namaBerkas);
}
try {
dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
String url = "http://10.0.2.2/locRemService/berkas/" + urlBerkas;
Request request = new Request(Uri.parse(url));
enqueue = dm.enqueue(request
.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)

BroadcastReceiver receiver = new BroadcastReceiver() {

if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
long downloadId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, 0);
Query query = new Query();
query.setFilterById(enqueue);
Cursor c = dm.query(query);
if (c.moveToFirst()) {

}
}
}
}
};

} catch (Exception e) {

}
} else {

@Override

Toast.makeText(getApplicationContext(), "Unduh Berkas...", Toast.LENGTH_LONG).show();
}
@Override
