Good day! I'm trying to install downloaded apk.I've uploaded it to
http://w194442.open.ge.tt/1/files/........?download
I download it by this code:
downloadUrl = urlStringChooser(myURL);
String downloadCompleteIntentName = DownloadManager.ACTION_DOWNLOAD_COMPLETE;
IntentFilter downloadCompleteIntentFilter = new
IntentFilter(downloadCompleteIntentName);
context = getApplicationContext();
context.registerReceiver(downloadCompleteReceiver, downloadCompleteIntentFilter);
String servicestring = Context.DOWNLOAD_SERVICE;
downloadmanager = (DownloadManager) getSystemService(servicestring);
Uri uri = Uri.parse(downloadUrl);
DownloadManager.Request request = new DownloadManager.Request(uri);
downloadID = downloadmanager.enqueue(request);
After that I get a broadcast signal from system that file downloaded :
private BroadcastReceiver downloadCompleteReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
long id = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, 0L);
if (id != downloadID) {
private BroadcastReceiver downloadCompleteReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
long id = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, 0L);
if (id != downloadID) {
Toast toast = Toast.makeText(getApplicationContext(), "downloadID FAIL", Toast.LENGTH_LONG);
toast.show();
return;
}
DownloadManager downloadManager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(id);
Cursor cursor = downloadManager.query(query);
if (!cursor.moveToFirst()) {
Toast toast = Toast.makeText(getApplicationContext(), "cursor.moveToFirst FAIL", Toast.LENGTH_LONG);
toast.show();
return;
}
int statusIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL != cursor.getInt(statusIndex)) {
Toast toast = Toast.makeText(getApplicationContext(), "cDownloadManager.STATUS_SUCCESSFUL != cursor.getInt(statusIndex)", Toast.LENGTH_LONG);
toast.show();
return;
}
int uriIndex = cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI);
String downloadedPackageUriString = cursor.getString(uriIndex);
uri = Uri.parse(downloadedPackageUriString);
if(uri != null) {
Toast toast = Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_LONG);
toast.show();
installUpdate(uri);
}
}
};
return;
}
DownloadManager downloadManager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(id);
Cursor cursor = downloadManager.query(query);
if (!cursor.moveToFirst()) {
Toast toast = Toast.makeText(getApplicationContext(), "cursor.moveToFirst
FAIL", Toast.LENGTH_LONG);
toast.show();
return;
}
int statusIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL != cursor.getInt(statusIndex)) {
Toast toast = Toast.makeText(getApplicationContext(),
"cDownloadManager.STATUS_SUCCESSFUL != cursor.getInt(statusIndex)",
Toast.LENGTH_LONG);
toast.show();
return;
}
int uriIndex = cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI);
String downloadedPackageUriString = cursor.getString(uriIndex);
uri = Uri.parse(downloadedPackageUriString);
if(uri != null) {
Toast toast = Toast.makeText(getApplicationContext(), "Success",
Toast.LENGTH_LONG);
toast.show();
installUpdate(uri);
}
}
};
Works fine for now. Then I call installUpdate(uri); to install it.
Intent promptInstall = new Intent(Intent.ACTION_VIEW);
promptInstall.setClass(context, MyActivity.class);
promptInstall.setDataAndType(goodUri,"application/vnd.android.package-archive");
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Log.d(TAG, "Before startActivity ");
startActivity(promptInstall);
And nothing happens. Logcat is
09-23 05:30:07.531 9492-9492/regulatory.securitycode.com.vpnupdate D/Updater﹕ Before

What do I do wrong?
Have you checked the "Install from Unknown sources" option in the Security Settings?

how can i implement Pause/Resume for my downloads? WITHOUT a library?
is it possible trough Download manager itself or i should use some other methods?
You can send message to the DownloadService you created, and invoke the DownloadManager to do the pause and resume action.
When DownloadManager enqueue a download task, you will get a id (long)
DownloadManager keep the download info in the ContentProvider, just update the ContentProvider info with the given id (long), if the network or other conditions satisfied the action will execute.
You can extends DownloadManager and create a pair of methods like below.
Pause Download
/**
* pause download
*
* #param ids the IDs of the downloads to be paused
* #return the number of downloads actually paused
*/
public int pauseDownload(long... ids) {
if (ids == null || ids.length == 0) {
// called with nothing to remove!
throw new IllegalArgumentException("input param 'ids' can't be null");
}
ContentValues values = new ContentValues();
values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_PAUSED);
values.put(Downloads.Impl.COLUMN_STATUS, Downloads.Impl.STATUS_PAUSED_BY_APP);
if (ids.length == 1) {
return mResolver.update(ContentUris.withAppendedId(mBaseUri, ids[0]), values,
null, null);
}
return mResolver.update(mBaseUri, values, getWhereClauseForIds(ids),
getWhereArgsForIds(ids));
}
Resume download
/**
* resume download
*
* #param ids the IDs of the downloads to be resumed
* #return the number of downloads actually resumed
*/
public int resumeDownload(long... ids) {
if (ids == null || ids.length == 0) {
// called with nothing to remove!
throw new IllegalArgumentException("input param 'ids' can't be null");
}
ContentValues values = new ContentValues();
values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_RUN);
values.put(Downloads.Impl.COLUMN_STATUS, Downloads.Impl.STATUS_RUNNING);
if (ids.length == 1) {
return mResolver.update(ContentUris.withAppendedId(mBaseUri, ids[0]), values,
null, null);
}
return mResolver.update(mBaseUri, values, getWhereClauseForIds(ids),
getWhereArgsForIds(ids));
}
I am always getting COLUMN_STATUS as STATUS_SUCCESSFUL even it fails due to insufficient space:
#Override
public void onReceive(Context context, Intent intent) {
if (intent == null) {
Utils.log(TAG, "Intent is NULL");
return;
}
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(intent.getAction())) {
DownloadManager downloadManager = (DownloadManager)
context.getSystemService(Context.DOWNLOAD_SERVICE);
long referenceId = intent.getLongExtra(
DownloadManager.EXTRA_DOWNLOAD_ID, -1L);
if (downloadManager != null) {
DownloadManager.Query dmQuery = new DownloadManager.Query();
dmQuery.setFilterById(referenceId);
try (Cursor cursor = downloadManager.query(dmQuery)) {
if (cursor != null && cursor.getCount() > 0) {
// The error is here
int columnIndex =cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (cursor.moveToFirst() && cursor.getInt(columnIndex) == DownloadManager.STATUS_SUCCESSFUL) {
} else {
Log.e(TAG, "fail");
}
}
} catch (Exception exception) {
Log.e(TAG, exception);
}
}
}
}
If your connection timeouts, you will get FAILED.
If it fails due to insufficient space, check the query columns COLUMN_TOTAL_SIZE_BYTES and COLUMN_BYTES_DOWNLOADED_SO_FAR to check if equal.
int bytes_total = cur.getInt(cur.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES));
int bytes_downloaded = cur.getInt(cur.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
I am using DownloadManager to download the following url:
http://dj-videos.us/Music/XclusiveSinGleTrack/320%20Kbps/November%202013/Yo%20Yo%20Honey%20Singh%20-%20Blue%20Eyes-[DJKANG.Com].mp3
But the downloading is failed. I even hit the url on browser and it works properly. Is it the problem of url parsing?

But I still need to know which format to use to parse url for DownloadManager.
The IllegalArgumentException occurs when the URL contains illegal characters such as [ ]. As mentioned in the comments, you need to encode such characters using URLEncoder.
I implemented it this way in my code -
private String checkUrl(String url) {
if(url.contains("[")) {
String[] a = url.split("\\[");
String b = "[" + a[1]; //contains text after [ e.g. [DJKANG.Com].mp3
url = a[0] + URLEncoder.encode(b, "UTF-8"); // encodes illegal characters
}
return url;
}
I am trying to download an Android app from a server using the DownloadManager class, install it and then detect when the installation is completed. I am using two receivers: one to detect the download process and the other to detect the install process. The first receiver works properly, but the second doesn't. What I am doing wrong?
DownloadManager dm = (DownloadManager) DownloadApplicationActivity.this.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request req = new DownloadManager.Request(Uri.parse(MY_LINK));
req.setTitle(MY_TITLE)
.setDescription("Downloading ....")
// download the package to the /sdcard/downlaod path.
.setDestinationInExternalPublicDir(
Environment.DIRECTORY_DOWNLOADS,
MY_PATH);
long enqueue = dm.enqueue(req);
BroadcastReceiver receiver= new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
Query query = new Query();
query.setFilterById(enqueue);
Cursor c =dm.query(query);
if (c.moveToFirst()) {
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c.getInt(columnIndex)) {
// show a notification bar.
NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,"",System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.flags |= Notification.FLAG_NO_CLEAR;
Intent i = new Intent(Intent.ACTION_VIEW);
// when the notification is clicked, install the app.
i.setDataAndType(Uri.fromFile(new File(Environment
.getExternalStorageDirectory() + APP_PATH)),"application/vnd.android.package-archive");
PendingIntent pendingIntent = PendingIntent.getActivity(
activity, 0, i, 0);
notification.setLatestEventInfo(activity, MY_TEXT, MY_TEXT,pendingIntent);
notification.number += 1;
notificationManager.notify( 0, notification);
//i want to detect the app's installation, I register a ne receiver
registerReceiver(installReceiver,new IntentFilter(Intent.ACTION_PACKAGE_ADDED));
}
}
};
BroadcastReceiver installReceiver= new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {
Uri data = intent.getData();
String packageName = data.getEncodedSchemeSpecificPart();
Log.i("The installed package is: ", "" + packageName);
}
}
};
I solved my problem, I added
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
intentFilter.addAction(Intent.ACTION_PACKAGE_INSTALL);
intentFilter.addDataScheme("package");
before the line :
registerReceiver(installReceiver, intentFilter);
You can try the code below. This way you can get all activities that can be called by an intent and if you know the activity name and it is present in list retrieved by queryIntentActivities()..you know it is installed.
public void callQrScan()
{
Intent intent1 = new Intent("com.google.zxing.client.android.SCAN");
if(isCallable(intent1)== true){
Context context = getApplicationContext();
CharSequence text = "Scan Niet Gelukt";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
else{
Context context = getApplicationContext();
CharSequence text = "Scan Niet Gelukt";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
Button tempbutton = (Button)findViewById(R.id.Button03);
tempbutton.setOnClickListener(new OnClickListener()
{
public void onClick(final View v)
{
callQrScan();
}
});
}
private boolean isCallable(Intent intent1) {
List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent1,
PackageManager.MATCH_DEFAULT_ONLY);
if(list.size() > 0)
return true ;
else
return false;
}
Hope it helps :)
I use DownloadManager for getting status of downloading, but it still doesn't work, it never jumps to condition if(c.moveToFirst()) and I don't know why. Could anybody help me, please?
private final BroadcastReceiver myReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(Intent.ACTION_SCREEN_OFF.equals(action)) {
DownloadManager downloadMgr = (DownloadManager)getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterByStatus(DownloadManager.STATUS_FAILED|DownloadManager.STATUS_PENDING|DownloadManager.STATUS_RUNNING|DownloadManager.STATUS_SUCCESSFUL);
Cursor c = downloadMgr.query(query);
if(c==null) {
//
}
else {
if(c.moveToFirst()) {
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
int status = c.getInt(columnIndex);
if(status == DownloadManager.STATUS_RUNNING){
//do something
}
}
}
}
}
};
Here are few link refer it.

sample code is below::
DownloadManager.Query query = null;
Cursor c = null;
DownloadManager downloadManager = null;
downloadManager = (DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
query = new DownloadManager.Query();
if(query!=null) {
query.setFilterByStatus(DownloadManager.STATUS_FAILED|DownloadManager.STATUS_PAUSED|DownloadManager.STATUS_SUCCESSFUL|
DownloadManager.STATUS_RUNNING|DownloadManager.STATUS_PENDING);
} else {
return;
}
c = downloadManager.query(query);
if(c.moveToFirst()) {
int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));
switch(status) {
case DownloadManager.STATUS_PAUSED:
break;
case DownloadManager.STATUS_PENDING:
break;
case DownloadManager.STATUS_RUNNING:
break;
case DownloadManager.STATUS_SUCCESSFUL:
break;
case DownloadManager.STATUS_FAILED:
break;
}
}
This is how I do it
//broadcastReceiver
private val receiver = object : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
val id = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1)
//call notify off NotificationManager passing in the id & notification
notificationManager.apply {
notify(NOTIFICATION_ID, createNotification())
}
//DownloadManager.Query() is used to filter DownloadManager queries
val query = DownloadManager.Query()
query.setFilterById(id)
val cursor = downloadManager.query(query)
if (cursor.moveToFirst()){
val status = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS))
when (status) {
DownloadManager.STATUS_SUCCESSFUL ->{
}
DownloadManager.STATUS_FAILED -> {
}
}
}
}
}
