我有一個致命的例外：AsyncTask＃1，同時嘗試將圖像上傳到網絡服務器從Android應用程序。我使用Bitmap和BitmapFactory來編碼圖像。Android HttpClient致命例外：AsyncTask＃1使用BitmapFactory
@Override
protected Void doInBackground(Void... params) {
Bitmap bitmapOrg = BitmapFactory.decodeFile(this.path);
ByteArrayOutputStream bao = new ByteArrayOutputStream();
if (bitmapOrg == null)
{
return null;
}
bitmapOrg.compress(Bitmap.CompressFormat.JPEG, 90, bao);
byte[] data = bao.toByteArray();
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost("http://192.168.20.162/sse_server/up.php");
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
//Set Data and Content-type header for the image
entity.addPart("file", new ByteArrayBody(data, "image/jpeg", "file"));
postRequest.setEntity(entity);
try {
HttpResponse response = httpClient.execute(postRequest);
//Read the response
String jsonString = EntityUtils.toString(response.getEntity());
Log.v("RequestInformation", "after uploading file " + jsonString);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
這裏是logcat的錯誤堆棧：
