I haven't found anything useful so far that suited my needs. I also needed that the upload got handled in the

background and in the most efficient way on Android. More than that, I also needed to show upload status in the

Android Notification Center.

So, after some research on the web I found that the best way to do this is to implement an IntentService and notify

status with broadcast intents. This way the logic is decoupled from the UI and it's much more reusable. By using an

have to deal with the nightmare of concurrency. Also, an IntentService is much more efficient than an AsyncTask, it

gets executed in the background and it's completely detached from the UI thread. If you need to show status in your UI,

read further and you'll discover how to do it very easily.

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.WAKE_LOCK" />

</ application>

add the following:

<service

<action android:name="com.alexbbb.uploadservice.action.upload"/>

</intent-filter>

</service>

In the <b>examples</b> folder you will find:

* a demo server-side php script that handles multipart form upload

To be able to compile and deploy the demo application, you also need to have <b>appcompat_v7</b> library. You may need to change the path to that library in the demo application's properties.

For detailed explanation of each parameter, please check JavaDocs.

public void upload(final Context context) {

"http://www.yoursite.com/yourscript");

/*

* Pass "uploaded_file" if you're using the test PHP script

*

* E.g. value of $_FILES["uploaded_file"]["name"] of the test PHP script

*/

"parameter-name",

"custom-file-name.extension",

"content-type"));

//and parameters

request.addParameter("parameter-name", "parameter-value");

//If you want to add a parameter with multiple values, you can do the following:

request.addParameter("array-parameter-name", "value1");

request.addParameter("array-parameter-name", "value2");

request.addParameter("array-parameter-name", "valueN");

//or

String[] values = new String[] {"value1", "value2", "valueN"};

request.addArrayParameter("array-parameter-name", values);

//or

List<String> valuesList = new ArrayList<String>();

valuesList.add("value1");

"upload completed successfully text"

"upload error text",

false);

try {

//Start upload service and display the notification

UploadService.startUpload(request);

} catch (Exception exc) {

//You will end up here only if you pass an incomplete UploadRequest

Log.e("AndroidUploadService", exc.getLocalizedMessage(), exc);

}

}

an abstract broadcast receiver has been implemented for you and you just need to extend it and add your custom code.

So to listen for the status of the upload service in an Activity for example, you just need to do the following:

public class YourActivity extends Activity {

private static final String TAG = "AndroidUploadService";

...

new AbstractUploadServiceReceiver() {

@Override

public void onProgress(String uploadId, int progress) {

+ uploadId + " is: " + progress);

}

@Override

public void onError(String uploadId, Exception exception) {

+ exception.getLocalizedMessage(), exception);

}

@Override

public void onCompleted(String uploadId,

String serverResponseMessage) {

+ ", " + serverResponseMessage);

}

};

@Override

protected void onResume() {

super.onResume();

uploadReceiver.register(this);

}

@Override

protected void onPause() {

super.onPause();

uploadReceiver.unregister(this);

}

}

If you want to monitor upload status in all of your activities, then just implement the BroadcastReceiver in your base activity class, from which all of your activities inherits and you're done.

For security reasons, the library doesn't accept self-signed certificates by default when using HTTPS connections, but you can enable them by calling:

AllCertificatesAndHostsTruster.apply();

before starting the upload service.

Let me know, and I'll be glad to include a link in the following list :)
