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));

On one of my device, the following code can't make my video appear in Gallery:
File file = new File(path);
Uri uri = Uri.fromFile(file);
Intent scanFileIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri);
activity.sendBroadcast(scanFileIntent);
So I use scanFile explicitly:
android.media.MediaScannerConnection.scanFile(activity, new String[]{file.getAbsolutePath()},
new String[]{"video/" + mMimeType}, null);
When my video is xxx.mpeg4, the value of mMimeType is mp4, the result is that the video can appear in MediaStore but I can't get the duration later(the returned value is always 0). Need help on this.
public static long[] getVideoDetail(Context context, Uri uri) {
long[] result = new long[] {DEFAULT_VIDEO_FRAME_WIDTH, DEFAULT_VIDEO_FRAME_HEIGHT, -1};
if(uri == null || (!ContentResolver.SCHEME_CONTENT.equals(uri.getScheme()))) {
return result;
}
String[] projection = new String[] {MediaStore.Video.Media.RESOLUTION, MediaStore.Video.VideoColumns.DURATION};
Cursor cursor = null;
boolean success = false;
try {
cursor = context.getContentResolver().query(uri, projection, null, null, null);
if (cursor.moveToFirst()) {
String resolution = cursor.getString(0);
if(!StringUtils.isEmpty(resolution)) {
int index = resolution.indexOf('x');
result[0] = Integer.parseInt(resolution.substring(0, index));
result[1] = Integer.parseInt(resolution.substring(index + 1));
if(result[0] != 0 && result[1] != 0) {
success = true;
}
if(result[0] > result[1]) {
swap(result, 0, 1);
}
}
result[2] = cursor.getLong(1);
if(result[2] >= 0 && success) {
success = true;
} else {
success = false;
}
}
if (null != cursor) {
cursor.close();
}
}
catch (Exception e) {
// do nothing
} finally {
try {
if (null != cursor) {
cursor.close();
}
} catch (Exception e2) {
// do nothing
}
}
if (!success) {
try {
ContentResolver contentResolver = context.getContentResolver();
String selection = MediaStore.Images.Media._ID + "= ?";
String id = uri.getLastPathSegment();
String[] selectionArgs = new String[]{ id };
cursor = contentResolver.query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, projection, selection, selectionArgs, null);
if (cursor.moveToFirst()) {
String resolution = cursor.getString(0);
if(!StringUtils.isEmpty(resolution)) {
int index = resolution.indexOf('x');

try {
if (cursor != null) {

}
} catch (Exception e) {
// do nothing
}
}
}
if(result[0] <= 0) {
result[0] = DEFAULT_VIDEO_FRAME_WIDTH;
}
if(result[1] <= 0) {
result[1] = DEFAULT_VIDEO_FRAME_HEIGHT;
}
return result;
}
As I see in your code you are requesting duration in your projection
String[] projection = new String[] {MediaStore.Video.Media.RESOLUTION, MediaStore.Video.VideoColumns.DURATION};
now you just need to retrieve it from the cursor like shown below:
long timeInMs = cursor.getLong(cursor.getColumnIndex(MediaStore.Video.VideoColumns.DURATION));
get help from MediaPlayer :
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(context, Uri.parse(uri));
} catch (IOException e) {
Log.d("-MS-","Cannot parse url");
e.printStackTrace();
}
int duration= mp.getDuration();
String[] projection = new String[] {MediaStore.Video.Media.RESOLUTION,duration};
I always get Duration by MediaPlayer.
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

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