Im writing an Android App. This App should upload some pictures to my server via POST. It is working if I use picture smaller then 1MB. But if i use larger images the log says me that the image was uploaded but the image is not on the server. The post_max_size is 4MB
My Method is from a stackoverflow solution and should work but it doesnt and I dont know why.
// http post
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("c_user_id", params[1]));
nameValuePairs.add(new BasicNameValuePair("c_task_id", params[2]));
nameValuePairs.add(new BasicNameValuePair("c_comment", params[3]));
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(phpPath + "insert_task.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
} catch (Exception e) {
Log.e("log_tag", "Error in http connection" + e.toString());
this.cancel(true);
}
String Tag = "UPLOADER";
String urlString = phpPath + "upload_task.php?user_id=" + params[1]
+ "&task_id=" + params[2];
HttpURLConnection conn = null;
String exsistingFileName = params[0];
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
try {

Log.e(Tag, "Inside second Method");
FileInputStream fileInputStream = new FileInputStream(new File(
exsistingFileName));
