I wrote an IntentService that dose both the things together with progress :
Add following Service class to your Application (also declare it in your app’s Manifest file) :
import android.app.IntentService;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.os.Handler;
import android.os.Looper;
import android.os.Parcel;
import android.os.Parcelable;
import android.os.ResultReceiver;
import android.util.Log;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URL;
import java.net.URLConnection;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;

Sample use case :
String serverFilePath = "http://www.colorado.edu/conflict/peace/download/peace_problem.ZIP";
String path = FileUtils.getDataDir(context).getAbsolutePath();
String fileName = "sample_download";
File file = new File(path, fileName);
String localPath = file.getAbsolutePath();
String unzipPath = FileUtils.getDataDir(context, "ExtractLoc").getAbsolutePath();
FileDownloadService.DownloadRequest downloadRequest = new FileDownloadService.DownloadRequest(serverFilePath, localPath);
downloadRequest.setRequiresUnzip(true);
downloadRequest.setDeleteZipAfterExtract(false);
downloadRequest.setUnzipAtFilePath(unzipPath);
FileDownloadService.OnDownloadStatusListener listener = new FileDownloadService.OnDownloadStatusListener() {
@Override
public void onDownloadStarted() {
}
@Override
public void onDownloadCompleted() {
}
@Override
public void onDownloadFailed() {
}
@Override
public void onDownloadProgress(int progress) {
}
};
FileDownloadService.FileDownloader downloader = FileDownloadService.FileDownloader.getInstance(downloadRequest, listener);
downloader.download(context);
Also you can use (if required)
FileUtils.java
import android.content.Context;
import java.io.File;
public class FileUtils {
public static File getDataDir(Context context) {
String path = context.getFilesDir().getAbsolutePath() + "/SampleZip";
File file = new File(path);
if(!file.exists()) {
file.mkdirs();
}
return file;
}
public static File getDataDir(Context context, String folder) {
String path = context.getFilesDir().getAbsolutePath() + "https://stackoverflow.com/" + folder;
File file = new File(path);
if(!file.exists()) {
file.mkdirs();
}
return file;
}
}
