I have tried 3 diffrent methods for sending a image from my Android to PHP.
All three gives the message "Missing inp_image name". I am thinking that I maybe am not sending the image as an image, but rather as some text ?
I am using this http request class in Android: https://github.com/kevinsawicki/http-request
Method 1 with encoding it to base64:
//String selectedFilePath = FilePath.getPath(context, imageUri);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;
Bitmap bm = BitmapFactory.decodeFile(destImage,options);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG,40,baos);
byte[] byteImage_photo = baos.toByteArray(); // bitmap object
//generate base64 string of image
String encodedImage = Base64.encodeToString(byteImage_photo,Base64.DEFAULT);
// Send image
HttpRequest request = HttpRequest.post(apiUrl);
request.part("inp_image", encodedImage);
stringResponse = request.body();
Method 2 - sending a input stream of image
HttpRequest request = HttpRequest.post(apiUrl);
request.part("inp_image", in); // sending input stream
stringResponse = request.body();
Method 3 - sending file:
String sourceFilename= FilePath.getPath(context, imageUri);
HttpRequest request = HttpRequest.post(apiUrl);
request.part("inp_image", new File(sourceFilename)); // sending input stream
stringResponse = request.body();

i also make sure that my android manifest is correct
I have Spent Day and Night trying to solve this problem, Browsed through numerous pages on the topic, Tried different codes of my own.
And it still happens. I am a beginner in Android. And please, please do help me. Is there no possible way to solve my problem?
this is my logcat
LogCat
Firstly, you should include your logcat in text form as a part of your question!
However, from what I can read from your screenshot the issue is in the onLocationChanged() method. Perform a check on "location" to see if it is null before trying to read it.
#Override
public void onLocationChanged(Location location) {
if(location != null){
double longitude = location.getLongitude();
double latitude = location.getLatitude();
textView.setText("Longitude:" + longitude + "\n" + "Latitude:" + latitude);
}
else{
Log.e(TAG, "onLocationChanged -- location is null!");
}
}
Note:
Just in case you didn't know the "TAG" is generally added to the beginning of most Android class like this:
public class MainActivity extends AppCompatActivity implements LocationListener {
private static final String TAG = MainActivity.class.getSimpleName();
Why MainActivity.class.getSimpleName() instead of just "MainActivity"? Because if you ever refactor your code, then the name will automatically be changed.
EDIT:
Have you added the necessary permissions in your manifest file?
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-feature android:name="android.hardware.location.gps"/>

Now your layout:

android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Multiple File Upload from CoderzHeaven"
/>
<Button
android:id="#+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get First File">
</Button>
<Button
android:id="#+id/Button02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get Second File">

<Button
android:id="#+id/upload"
android:layout_width="wrap_content"

/>
<TextView
android:id="#+id/res"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

</LinearLayout>
of course, include the internet permission in your manifest:
<uses-permission android:name="android.permission.INTERNET" />

I am using volley to download file using an asynchronous task.I want to show the progress with percentage while the file is being downloaded. But the problem is that the async task is started when the response has come. I can't find any way to track the progress before final response has completely come.
I didn't find any method in JsonRequest that can be used for this.
Below is the onResponse method of request class that extends JsonRequest that i am using.
protected Response<T> parseNetworkResponse(NetworkResponse response) {
if (response.statusCode >= 200 && response.statusCode <= 299) {
// If the status is correct, we return a success but with a null object, because the server didn't return anything
return Response.success(null, HttpHeaderParser.parseCacheHeaders(response));
}
else {
try {
if (downloadFlag) {
DownloadFileAsyncTask downloadFileAsyncTask = new DownloadFileAsyncTask(mContext, fileNameAndExtn,mNotifyManager,mBuilder,mDownloadNotificationUniqueId);
downloadFileAsyncTask.execute(response.data);
} else if (isResponseByteArr) {
return (Response<T>) Response.success(response.data, HttpHeaderParser.parseCacheHeaders(response));
} else {
String json = null;
if (isGzipped(response)) {
json = gzipDecompress(response.data);
} else {
json = new String(response.data,HttpHeaderParser.parseCharset(response.headers));
}
T parsedObject = gson.fromJson(json, clazz);
return Response.success(parsedObject, HttpHeaderParser.parseCacheHeaders(response));
}
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JsonSyntaxException e) {
return Response.error(new ParseError(e));
} catch (IOException e) {
e.printStackTrace();

not sure you can do this with volley but easy solution for you as you are already using AsyncTask. Here is a link http://www.androidhive.info/2012/04/android-downloading-file-by-showing-progress-bar/ he did the same thing which you are looking.
I solved this problem by creating the notification as soon as the user clicks on download and then the async task notifies after the download is completed but i was not able to show the exact progress while downloading.
I am developing an app to uploading ,displaying and downloading files from G Drive. Unfortunately When downloading I am getting
com.google.api.client.http.HttpResponseException: 401 Unauthorized.
Please help me to solve this problem.

Nowhere in your code are you setting the Authorization header.
You need something like
setRequestProperty("Authorization", "OAuth " + "***ACCESS_TOKEN***");
For any 401/403 errors it's well worth getting your request working on the Oauth. Try this out

I have recently implement wifi direct into my project,my aim is pass string value between two wifidirect connected devices when some of my app condition satisfies.right now i have listed all peers and also made connection between the selected peer.what my idea is to pass a json file between the devices.so before try to execute that idea i try to pass a image file between two devices.i followed the steps from the android wifidirect tutorial.listing peers and the connection between the peers is success full but i cant pass the data between the devices.the follwing is my code.

These are files used in my code .form the tutorial i have found that
new FileServerAsyncTask(getApplicationContext())
.execute();
where the the incomming data is begin accepted so when i need to execute this asyn thread,so anyone help me in which portion i have made the mistake.how can i transfer the file between devices .
The android code from the demo wifi direct project is able to pass file is unidirectional. ie. you can send file from client to server only. You need furthur modifications to make it work in both direction.
EDIT 2:
For that you need to know the IP address of both connected peers. Use the following function which I made following various sources with my modifications wherever appropriate.
public static String getIpAddress() {
try {
List<NetworkInterface> interfaces = Collections
.list(NetworkInterface.getNetworkInterfaces());
/*
* for (NetworkInterface networkInterface : interfaces) { Log.v(TAG,
* "interface name " + networkInterface.getName() + "mac = " +
* getMACAddress(networkInterface.getName())); }
*/
for (NetworkInterface intf : interfaces) {
if (!getMACAddress(intf.getName()).equalsIgnoreCase(
Globals.thisDeviceAddress)) {
// Log.v(TAG, "ignore the interface " + intf.getName());
// continue;
}
if (!intf.getName().contains("p2p"))
continue;
Log.v(TAG,
intf.getName() + " " + getMACAddress(intf.getName()));
List<InetAddress> addrs = Collections.list(intf
.getInetAddresses());
for (InetAddress addr : addrs) {
// Log.v(TAG, "inside");
if (!addr.isLoopbackAddress()) {
// Log.v(TAG, "isnt loopback");
String sAddr = addr.getHostAddress().toUpperCase();
Log.v(TAG, "ip=" + sAddr);
boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr);
if (isIPv4) {
if (sAddr.contains("192.168.49.")) {
Log.v(TAG, "ip = " + sAddr);
return sAddr;
}
}
}
}
}
} catch (Exception ex) {
Log.v(TAG, "error in parsing");
} // for now eat exceptions
Log.v(TAG, "returning empty ip address");
return "";
}
public static String getMACAddress(String interfaceName) {
try {
List<NetworkInterface> interfaces = Collections
.list(NetworkInterface.getNetworkInterfaces());
for (NetworkInterface intf : interfaces) {
if (interfaceName != null) {
if (!intf.getName().equalsIgnoreCase(interfaceName))
continue;
}
byte[] mac = intf.getHardwareAddress();
if (mac == null)
return "";
StringBuilder buf = new StringBuilder();
for (int idx = 0; idx < mac.length; idx++)
buf.append(String.format("%02X:", mac[idx]));
if (buf.length() > 0)
buf.deleteCharAt(buf.length() - 1);
return buf.toString();
}
} catch (Exception ex) {
} // for now eat exceptions
return "";
/*
* try { // this is so Linux hack return
* loadFileAsString("/sys/class/net/" +interfaceName +
* "/address").toUpperCase().trim(); } catch (IOException ex) { return
* null; }

I think the way you initialize client makes the problem.
You need to call this
new FileServerAsyncTask(getApplicationContext()).execute();
after the connection is established and check if it's a client.
Now you are creating a client socket only if it is a server(group owner) and always when you call to get a MAC address.
So on the client side you are not intializing the socket and so not able to receive the file.
Once check the WifiDirect sample demo provided in the SDK, you may get more idea.
