Instead of using AsyncTask to download images from URL. You can use libraries such as Glide or Picasso to do it quickly just in one line. But if you don't want to use libraries than you could use DownloadManager to download it and save it in a file. You can check this tutorial or other tutorials on the web for the implementation of DownloadManager.

Android Apk which is downloaded programmatically from Google Drive, is not installing, says "Unable to parse package"

I'm working on sample project. I'm trying to download apk from Google drive (by sharable link) and trying to install an update to already existing application
This is my code to download and install the update:
class DownloadApkTask extends AsyncTask<Void, Void, Void>{
#Override
protected Void doInBackground(Void... params) {
InputStream input = null;
OutputStream output = null;
HttpURLConnection connection = null;
try {
URL url = new URL("https://drive.google.com/file/d/0B2U-9Im6jS66dHFXLTFIX0JQbnM/view?usp=sharing");
connection = (HttpURLConnection) url.openConnection();
connection.connect();
if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
String error = "Server returned HTTP " + connection.getResponseCode()
+ " " + connection.getResponseMessage();
}
// download the file
input = connection.getInputStream();
output = new FileOutputStream("/sdcard/tcr_update.apk");
byte data[] = new byte[4096];
long total = 0;
int count;
while ((count = input.read(data)) != -1) {
// allow canceling with back button
if (isCancelled()) {
input.close();
return null;
}
total += count;
output.write(data, 0, count);
}
} catch (Exception e) {
Log.d("TAG", "doInBackground: "+e.getMessage());
} finally {
try {
if (output != null)
output.close();
if (input != null)
input.close();
} catch (IOException ignored) {
}
if (connection != null)
connection.disconnect();
}
return null;
}
Below code is for opening the application installer
#Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
File apkFile = new File("/sdcard/tcr_update.apk");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");
startActivity(intent);
}

How to Update My Android app From My Server?

Please help me to add update code to my app to be update from my server thank you
nothing worked from net , i need complete guide

You can't install your app without users permission and root access but you can download your applications new version from server then ask users for install. Here is an example:
{
PackageManager manager = context.getPackageManager();
try {
PackageInfo info = manager.getPackageInfo(context.getPackageName(), 0);
version = info.versionName;
if (newversion.replace(".", "") < version.replace(".", "")) {
new DownloadFileFromURL().execute("http://exampl.com/Content/files/example.apk");
}
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}
private class DownloadFileFromURL extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
dialog = onCreateDialog();
}
#Override
protected String doInBackground(String... f_url) {
int count;
try {
File file = new File(Environment.getExternalStorageDirectory() + "/example.apk");
if (file.exists()) {
file.delete();
}
URL url = new URL(f_url[0]);
URLConnection conection = url.openConnection();
conection.connect();
int lenghtOfFile = conection.getContentLength();
pDialog.setMax(lenghtOfFile / 1024);
InputStream input = new BufferedInputStream(url.openStream(), 8192);
OutputStream output = new FileOutputStream(Environment.getExternalStorageDirectory() + "/example.apk");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
publishProgress(total / 1024 + "");
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
} catch (Exception ignored) {
}
return null;
}

And here is my async task
private void startDownloadall() {
String fileURL = dload_all;
fileURL = fileURL.replace(" ", "%20");
new DownloadFileAsync1().execute(fileURL);
Toast.makeText(getApplicationContext(), "Downloading...start all", Toast.LENGTH_LONG).show();
}
class DownloadFileAsync1 extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
//showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
#Override
protected String doInBackground(String... aurl) {
try {
String fileURL = dload_all;
fileURL = fileURL.replace(" ", "%20");
URL u = new URL(fileURL);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
String PATH = getDir("ebook", MODE_PRIVATE).toString();
String ebookfile = "";
//String filename = id[index];
String filename = id_all;
if(fileURL.endsWith("pdf"))
ebookfile = filename+".pdf";
else
ebookfile = filename+".epub";
bookfile = ebookfile;
Global.setBookfile(bookfile);
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, ebookfile);
FileOutputStream fos = new FileOutputStream(outputFile);
lenghtOfFilee = c.getContentLength();
InputStream in = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
long total = 0;
while ((len1 = in.read(buffer)) > 0) {
total += len1; //total = total + len1
//publishProgress("" + (int)((total*100)/lenghtOfFilee));
fos.write(buffer, 0, len1);
}
fos.close();
} catch (Exception e) {
// Log.d("Downloader", e.getMessage());
}
return null;
}
protected void onProgressUpdate(String... progress) {
// Log.d("ANDRO_ASYNC",progress[0]);
//mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}
#Override
protected void onPostExecute(String unused) {
Global.setBookfile(bookfile);
Toast.makeText(getApplicationContext(), "Downloading..."+lenghtOfFilee, Toast.LENGTH_LONG).show();
checkdownloadall();
//dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
}
}

An asynchronous task runs on a background thread, so you directly access variable dload_all in function doInBackground() that is not thread safe. Maybe you can try:
private void startDownloadall() {
//String fileURL = dload_all;
//fileURL = fileURL.replace(" ", "%20");
new DownloadFileAsync1().execute(dload_all, id_all);
Toast.makeText(getApplicationContext(), "Downloading...start all", Toast.LENGTH_LONG).show();
}
class DownloadFileAsync1 extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
//showDialog(DIALOG_DOWNLOAD_PROGRESS);
}
#Override
protected String doInBackground(String... aurl) {
try {
String fileURL = args[0];
fileURL = fileURL.replace(" ", "%20");
URL u = new URL(fileURL);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
String PATH = getDir("ebook", MODE_PRIVATE).toString();
String ebookfile = "";
//String filename = id[index];
String filename = args[1];
if(fileURL.endsWith("pdf"))
ebookfile = filename+".pdf";
else
ebookfile = filename+".epub";
bookfile = ebookfile;
Global.setBookfile(bookfile);
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, ebookfile);
FileOutputStream fos = new FileOutputStream(outputFile);
lenghtOfFilee = c.getContentLength();
InputStream in = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
long total = 0;
while ((len1 = in.read(buffer)) > 0) {
total += len1; //total = total + len1
//publishProgress("" + (int)((total*100)/lenghtOfFilee));
fos.write(buffer, 0, len1);
}
fos.close();
} catch (Exception e) {
// Log.d("Downloader", e.getMessage());
}
return null;
}
protected void onProgressUpdate(String... progress) {
// Log.d("ANDRO_ASYNC",progress[0]);
//mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}
#Override
protected void onPostExecute(String unused) {
Global.setBookfile(bookfile);
Toast.makeText(getApplicationContext(), "Downloading..."+lenghtOfFilee, Toast.LENGTH_LONG).show();
checkdownloadall();
//dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
}
}
