この単純なダウンロードを取得して画像を保存しようとしていますが、接続タイムアウト例外が発生し続けます。
私の知る限り、Webアドレスは機能するはずです
new DownloadImageTask();
private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
protected Bitmap doInBackground(String... urls) {
String urldisplay = "http://masterzangetsu.eu/Apps/BandWallpapers/Blink182/1_thumbnail.png";
Bitmap bitmap = null;
try {
InputStream in = new java.net.URL(urldisplay).openStream();
bitmap = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return bitmap;
}
@Override
protected void onPreExecute() {
}
@Override
protected void onProgressUpdate(Void... values) {
}
protected void onPostExecute(Bitmap bitmap) {
File sdCardDirectory = Environment.getExternalStorageDirectory();
File image = new File(sdCardDirectory, "test.png");
boolean success = false;
// Encode the file as a PNG image.
FileOutputStream outStream;
try {
outStream = new FileOutputStream(image);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream);
/* 100 to keep full quality of the image */
outStream.flush();
outStream.close();
success = true;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Image saved with success",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during image saving", Toast.LENGTH_LONG).show();
}
}
}
そして、ここに出力があります
