public string Uploadfile()
{
string msg = "";
try
{
HttpPostedFile file = HttpContext.Current.Request.Files["file"];
string saveFile = file.FileName;
//code to save the file

Please tell me where I am missing in my code...

This code works for me...

{
if (file == null)
return uploadedfile ;
//response = Request.CreateResponse(HttpStatusCode.NotFound, "");
int count; int sum = 0;
byte[] buffer = new byte[file.ContentLength];
int length = (int)file.InputStream.Length;
buffer = new byte[length];
while ((count = file.InputStream.Read(buffer, sum, length - sum)) > 0)
sum += count;
FileVM fileObj = new FileVM();
NameValueCollection parameters = HttpContext.Current.Request.Params;
if (parameters.Keys.Count > 0)
{
fileObj.fileId = "";
fileObj.fileName = file.FileName.ToString();
fileObj.fileType = file.ContentType;
fileObj.filedata = "";
fileObj.LastDownLoad = parameters.GetValues("LastDownLoad")[0];
ServicecltClients srv = new ServicecltClients();
uploadedfile.FileId = srv.InsertDocumentAndRelatedClient(fileObj, buffer);
uploadedfile.FileType = fileObj.fileType;

Best method to send image and a text from android to wcf service

I need to send an image and text from android to wcf service, tried with http client with multipart but no luck, kindly suggest.
send image using multipartBuilder and send text separately as json via http url connection, the below code for sending image to wcf service is this
Android code
public String postFiless( byte[] imgbyt, String urlString) throws Exception {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(urlString);
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
byte[] data = imgbyt;
String fileName = String.format("File_%d.jpg",new Date().getTime());
ByteArrayBody bab = new ByteArrayBody(data, fileName);
builder.addPart("image", bab);
final HttpEntity entity = builder.build();
post.setEntity(entity );
HttpResponse response = client.execute(post);
Log.e("result code", ""+response.getStatusLine().getStatusCode());
return getContent(response);
}
public static String getContent(HttpResponse response) throws IOException {
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String body = "";
String content = "";
while ((body = rd.readLine()) != null)
{
content += body + "\n";
}
return content.trim();
}

I am not able to copy it to any folder location in sdcard.
I would like to save the file to a pre-mentioned folder location in sdcard with the same name as the original file name was uploaded from my html page.

1)Not able to get correct location of temp file.
2)Not getting original filename that the form was posted with

} catch (IOException ioe) {
return getResponse("Internal Error IO Exception: " + ioe.getMessage());
} catch (ResponseException re) {
return new Response(re.getStatus(), MIME_PLAINTEXT, re.getMessage());
}
}
uri = uri.trim().replace(File.separatorChar, '/');
if (uri.indexOf('?') >= 0) {
uri = uri.substring(0, uri.indexOf('?'));
}
// Other implementation goes here...
if ("/uploadfiles".equalsIgnoreCase(uri)) {
String filename, tmpFilePath;
File src, dst;
for (Map.Entry entry : parms.entrySet()) {
if (entry.getKey().toString().substring(0, 8).equalsIgnoreCase("filename")) {
filename = entry.getValue().toString();
tmpFilePath = files.get(entry.getKey().toString());
dst = new File(mCurrentDir, filename);
if (dst.exists()) {
return getResponse("Internal Error: File already exist");
}
src = new File(tmpFilePath);
if (! copyFile(src, dst)) {
return getResponse("Internal Error: Uploading failed");
}
}
}
return getResponse("Success");
}
return getResponse("Error 404: File not found");
}
private boolean deleteFile(File target) {
if (target.isDirectory()) {
for (File child : target.listFiles()) {
if (! deleteFile(child)) {
return false;
}
}
}
return target.delete();
}
private boolean copyFile(File source, File target) {
if (source.isDirectory()) {
if (! target.exists()) {
if (! target.mkdir()) {
return false;
}
}
String[] children = source.list();
for (int i = 0; i < source.listFiles().length; i++) {
if (! copyFile(new File(source, children[i]), new File(target, children[i]))) {
return false;
}
}
} else {
try {
InputStream in = new FileInputStream(source);
OutputStream out = new FileOutputStream(target);
byte[] buf = new byte[65536];
int len;
while ((len = in.read(buf)) > 0) {

To allow multiple file upload:
<input type="file" name="filename" multiple>
The same issue existed in the 2.2.1 branch. Following the same logic, I fixed the same function with a few lines of code change.
Add a counter pcount at the beginning of the function:
private void decodeMultipartFormData(String boundary, String encoding, ByteBuffer fbuf, Map<String, String> parms, Map<String, String> files) throws ResponseException {
int pcount = 1;
try {
Then use the counter to update the keyname if filename is not empty:
while (matcher.find()) {
String key = matcher.group(1);
if ("name".equalsIgnoreCase(key)) {
part_name = matcher.group(2);
} else if ("filename".equalsIgnoreCase(key)) {
file_name = matcher.group(2);
// add these two line to support multiple
// files uploaded using the same field Id
if (!file_name.isEmpty()) {
if (pcount > 0)
part_name = part_name + String.valueOf(pcount++);
else
pcount++;
}
}
}
Maybe late, but just for latecommers just like me.
Explained before, the client use okhttp upload a file just like the follow code:
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
//sourceFile is a File as you know
.addFormDataPart("image_file_1", "logo-square1.png", RequestBody.create(MediaType.parse("image/png"), sourceFile))
.build();
Request request = new Request.Builder()
.url(url)
.post(requestBody)
.build();
Response response = client.newCall(request).execute();
The follow code is what you want
#Override
public Response serve(IHTTPSession session) {
Method method = session.getMethod();
// ▼ 1、parse post body ▼
Map<String, String> files = new HashMap<>();
if (Method.POST.equals(method) || Method.PUT.equals(method)) {
try {
session.parseBody(files);
} catch (IOException ioe) {
return getResponse("Internal Error IO Exception: " + ioe.getMessage());
} catch (ResponseException re) {
return newFixedLengthResponse(re.getStatus(), MIME_PLAINTEXT, re.getMessage());
}
}
//after the body parsed, by default nanoHTTPD will save the file to cache and put it into params( "image_file_1" as key and the value is "logo-square1.png");
//files key is just like "image_file_1", and the value is nanoHTTPD's template file path in cache
// ▲ 1、parse post body ▲
// ▼ 2、copy file to target path xiaoyee ▼
Map<String, String> params = session.getParms();
for (Map.Entry<String, String> entry : params.entrySet()) {
final String paramsKey = entry.getKey();
if (paramsKey.contains("image_file_1")) {
final String tmpFilePath = files.get(paramsKey);
final String fileName = paramsKey;
final File tmpFile = new File(tmpFilePath);
final File targetFile = new File(mCurrentDir + fileName);
LogUtil.log("copy file now, source file path: %s,target file path:%s", tmpFile.getAbsoluteFile(), targetFile.getAbsoluteFile());
//a copy file method just what you like
copyFile(tmpFile, targetFile);
//maybe you should put the follow code out
return getResponse("Success");
}
}
// ▲ 2、copy file to target path xiaoyee ▲
return getResponse("Error 404: File not found");
}

What is the function of "Intent.ACTION_PRE_BOOT_COMPLETED"?

I want to know the exact functionality of Intent.ACTION_PRE_BOOT_COMPLETED. Currently, my requirement is to complete the task before the completion of booting of the device, i.e. before the call of Intent.ACTION_BOOT_COMPLETED.
Can anyone guide me on how to proceed to fulfill the requirement? Any help in this regard will be well appreciated.
ACTION_PRE_BOOT_COMPLETED is sended in ActivityManagerService.java::systemReady.
But to received it, the uid of your application must be system(1000).
for (int i=ris.size()-1; i>=0; i--) {
if ((ris.get(i).activityInfo.applicationInfo.flags
&ApplicationInfo.FLAG_SYSTEM) == 0) {
ris.remove(i);
}
}
Further more, this broadcast could only be received once in each upgrade( not very sure here, maybe should be each wipe data).
Note code below, if the target is in lastDoneReceivers, it will be removed.
ArrayList<ComponentName> lastDoneReceivers = readLastDonePreBootReceivers();
final ArrayList<ComponentName> doneReceivers = new ArrayList<ComponentName>();
for (int i=0; i<ris.size(); i++) {
ActivityInfo ai = ris.get(i).activityInfo;
ComponentName comp = new ComponentName(ai.packageName, ai.name);
if (lastDoneReceivers.contains(comp)) {
ris.remove(i);
i--;
}
}
lastDoneReceivers is read from file /data/system/called_pre_boots.dat.
private static File getCalledPreBootReceiversFile() {
File dataDir = Environment.getDataDirectory();
File systemDir = new File(dataDir, "system");
File fname = new File(systemDir, "called_pre_boots.dat");
return fname;
}
static final int LAST_DONE_VERSION = 10000;
private static ArrayList<ComponentName> readLastDonePreBootReceivers() {
ArrayList<ComponentName> lastDoneReceivers = new ArrayList<ComponentName>();
File file = getCalledPreBootReceiversFile();
FileInputStream fis = null;
try {
fis = new FileInputStream(file);
DataInputStream dis = new DataInputStream(new BufferedInputStream(fis, 2048));
int fvers = dis.readInt();
if (fvers == LAST_DONE_VERSION) {
String vers = dis.readUTF();
String codename = dis.readUTF();
String build = dis.readUTF();
if (android.os.Build.VERSION.RELEASE.equals(vers)
&& android.os.Build.VERSION.CODENAME.equals(codename)
&& android.os.Build.VERSION.INCREMENTAL.equals(build)) {
int num = dis.readInt();
while (num > 0) {
num--;
String pkg = dis.readUTF();
String cls = dis.readUTF();
lastDoneReceivers.add(new ComponentName(pkg, cls));
}
}
}
} catch (FileNotFoundException e) {
} catch (IOException e) {
Slog.w(TAG, "Failure reading last done pre-boot receivers", e);
} finally {
if (fis != null) {
try {
fis.close();
} catch (IOException e) {
}
}
}
return lastDoneReceivers;
}
There is no such action as ACTION_PRE_BOOT_COMPLETED. I think that you normally can't fill your requirement. May be there is some mechanism for system signed apps to do that.

Read HTML file from assets

I have an html file in assets, aaa.html.
I want to read the contents of html file and replace it from another string.
Is this way is right or is there any other option.
my code:
File f = new File("file:///android_asset/aaa.html");
FileReader fr = new FileReader(f);
BufferedReader br = new BufferedReader(fr);
But its giving file not found, where as loading in web view loads the file.
InputStream is = getAssets().open("aaa.html");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
String str = new String(buffer);
str = str.replace("old string", "new string");
If you want to load file in webview then use this
mWebView.loadUrl("file:///android_asset/myfile.html");
you want to replace content inside Html file tags so the solution class code is here..
public class CardDetail {
public static String newHtmlString = "";
// private Context context;
#SuppressWarnings("rawtypes")
public String getNewHtmlString(String htmlString, HashMap hm) {
try {
StringTokenizer st = new StringTokenizer(htmlString, "##");
CardDetail.newHtmlString = "";
while (st.hasMoreTokens()) {
String token = st.nextToken();
CardDetail.newHtmlString += token;
if (st.hasMoreTokens()) {
String token2 = st.nextToken();
if (token2.equals("NAME") || token2.equals("POSITION") || token2.equals("COMPANY") || token2.equals("PHOTOURL"))
CardDetail.newHtmlString += hm.get(token2);
if (token2.equals("SKYPE_CONTAINER1")
|| token2.equals("TWITTER_CONTAINER1")
|| token2.equals("PHONENUMBER_CONTAINER1")
|| token2.equals("EMAIL_CONTAINER1")
|| token2.equals("ADDRESS_CONTAINER1")) {
String replaceString = st.nextToken();
String tokenMiddle = (String) hm.get(st.nextToken());
if (!tokenMiddle.equals("")) {
replaceString += tokenMiddle;
CardDetail.newHtmlString += replaceString + st.nextToken();
st.nextElement();
} else {
st.nextElement();
st.nextElement();
}
}
}
}
// Log.i("convertedHTMLString", newHtmlString);
return CardDetail.newHtmlString;
// htmlString = "<img src='" + hm.get("PHOTOURL") + "' width=80 height=80>";
// return htmlString;
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
return null;
}
#SuppressWarnings("unchecked")
public HashMap<?, ?> getProfileHashMap(JSONObject jsonObject) {
#SuppressWarnings("rawtypes")
HashMap hm = new HashMap();
jsonObject = (new JSONConverterClass()).convertJsonObjectToCardDetail(jsonObject);
try {
hm.put("EMAIL", jsonObject.getString("email"));
hm.put("NAME", jsonObject.getString("firstname") + " " + jsonObject.getString("lastname"));
hm.put("COMPANY", jsonObject.getString("company_name"));
hm.put("POSITION", jsonObject.getString("position"));
hm.put("WEBSITE", jsonObject.getString("website"));
hm.put("PHONENUMBER", jsonObject.getString("phonenumber"));
hm.put("PHOTOURL", jsonObject.getString("picture_url"));
hm.put("SKYPE", jsonObject.getString("skype_username"));
hm.put("TWITTER", jsonObject.getString("twitter_username"));
hm.put("ADDRESS", jsonObject.getString("generic_location"));
} catch (Exception e) {
e.printStackTrace();
}
return hm;
}
}
convertJsonObjectToCardDetail this class just replace string with values from Json
hope this solves your problem ....
