How to send the correct order of information to webservice?

Question

I have some videos files in a Android directory and I want execute each one using Intent. So far no problem, however I need save which video is running (log) in my webservice, so that, I make a asynchronous request, using retrofit 1.9.0, after startActivity(intent). My problem is: the log is not save in the right order. All logs are save with the same hour.

This is my function:

    File sdCardRoot = Environment.getExternalStorageDirectory();
    Intent intent = new Intent(Intent.ACTION_VIEW);

    for (int i = 0; i < videoListFromDevice.size(); i++) {

        if (isFileInDirectory(videoListFromDevice.get(i).name)) {

            File file = new File(Environment.getExternalStorageDirectory() + "/Videos/" + videoListFromDevice.get(i).name + ".mp4");
            intent.setDataAndType(Uri.fromFile(file), "video/mp4");
            intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
            getContext().startActivity(intent);

            getPresenter().sendLogVideo(MainPresenter.DEFAULT_NAME, videoListFromDevice.get(i).name);

        }
    }

Where videoListFromDevice is a local list of videos.

Can someone help me?

Thanks.

Logs are executed in a task sequence execution, You should use the Log.v(), Log.d(), Log.i(), Log.w(), and Log.e() methods to Write/Trace logs. You can then view the logs in logcat.

For ex, Declare a TAG constant in your class:

private static final String TAG = "VideoActivity";

and use that in subsequent calls to the log methods.

Something like this: Log.d(TAG, "videoName=" + video);

For more info see Log | Android Documentation

EDIT:

You can fetch logcat data as follows:

Process process = Runtime.getRuntime().exec("logcat -d");
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));

StringBuilder log = new StringBuilder();
String data;
while ((data= bufferedReader.readLine()) != null) {
     log.append(data);
   }
TextView textView = (TextView) findViewById(R.id.textViewlog);
textView.setText(log.toString());

Don't forgot to add permission:

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

To get data for particular TAG: replace logcat -d with logcat -d -s YourTag
