So I basically have a List of URIs, each has a .jpeg file, and I want to show this list like a GIF file (not necessesary to make a gif, only to display).
So after a research I found the AnimationDrawble object, converted each URI into Drawable and added it as a frame to AnimationDrawable.
This is my code:
AnimationDrawable ad = new AnimationDrawable();
Drawable[] dr = new Drawable[position+1];
ProgressItem pi;
try {
for (int i = 0; i <= position; i++) {
pi = progress.get(i);
try {
dr[i] = drawableFromUrl(pi.getImage());
} catch (IOException ios) {
Toast.makeText(activity, ios.getMessage(), Toast.LENGTH_SHORT).show();
}
}
}
catch(Exception ex)
{
Toast.makeText(activity, ex.getMessage(), Toast.LENGTH_SHORT).show();
}
Intent i = new Intent(activity,ProgressImage.class);
DataWraper.setItems(dr);
drawableFromUrl:
public Drawable drawableFromUrl(String url) throws IOException {
Bitmap x;
HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
MyDownloadTask mdt = new MyDownloadTask();
try{
mdt.execute(connection);
}
catch(Exception ex)
{
Toast.makeText(activity, ex.getMessage(), Toast.LENGTH_SHORT).show();
}
InputStream input = mdt.getInputStream();
x = BitmapFactory.decodeStream(input);
return new BitmapDrawable(x);
}
The implementation part:
Glide.with(this)
.load(ad)
.into(progressImage);
When I'm trying to Glide the AnimationDrawble into the ImageView I get the following exception:
java.lang.IllegalArgumentException: Unknown type class android.graphics.drawable.AnimationDrawable.
This made me hesistate the way I'm trying to pull this off. Should this be this complicated?
If this is the right way, what am I doing wrong? maybe there's another way of doing so? I'd love to get some details. Thanks in advance!

Not sure if you're open to any 3rd party libraries, but i used this one for gifs before and it worked quite well for me
I have created a simple application which is supposed to download large zip files. After some R&D I came to the conclusion that I have to use Download Manager to achieve this. I want the download to resume automatically if the device is restarted or in case of unstable internet connectivity. Right now, the code is able to download large files as expected, but in case of internet connectivity fluctuations or system restart, it stops downloading.
The activity:
public class MainActivity extends ActionBarActivity {
String Download_path = "http://wickedbrains.com/map/mumbai.zip";
String Download_ID = "DOWNLOAD_ID";
SharedPreferences preferenceManager;
DownloadManager downloadManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
preferenceManager = PreferenceManager.getDefaultSharedPreferences(this);
downloadManager = (DownloadManager)getSystemService(DOWNLOAD_SERVICE);
Button btnDownload = (Button)findViewById(R.id.download);
btnDownload.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View arg0) {
// Locate storage location
String filepath = "";
File folder = new File(
Environment.getExternalStorageDirectory() + "/osmdroid");
boolean success = true;
if (!folder.exists()) {
success = folder.mkdir();
}
if (success) {
// Do something on success
filepath = Environment.getExternalStorageDirectory()
.getPath() + "/osmdroid";
// Deleting if zip file exists
File folder2 = Environment.getExternalStorageDirectory();
String fileName = folder2.getPath() + "/osmdroid/mumbai.zip";
File myFile = new File(fileName);
if(myFile.exists())
myFile.delete();
}
//Starting download manager to download file
Uri Download_Uri = Uri.parse(Download_path);
DownloadManager.Request request = new DownloadManager.Request(Download_Uri);
long download_id = downloadManager.enqueue(request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI |DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false)
.setTitle("Test")
.setDescription("Map Download")
.setDestinationInExternalPublicDir("/osmdroid","mumbai.zip"));
// long download_id = downloadManager.enqueue(request);
//Save the download id
Editor PrefEdit = preferenceManager.edit();
PrefEdit.putLong(Download_ID, download_id);
PrefEdit.commit();
}});
}
#Override

// TODO Auto-generated method stub
super.onResume();

}
#Override

// TODO Auto-generated method stub
super.onPause();
unregisterReceiver(downloadReceiver);
}
private BroadcastReceiver downloadReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(preferenceManager.getLong(Download_ID, 0));
Cursor cursor = downloadManager.query(query);
if(cursor.moveToFirst()){
int columnIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
int status = cursor.getInt(columnIndex);
int columnReason = cursor.getColumnIndex(DownloadManager.COLUMN_REASON);
int reason = cursor.getInt(columnReason);
if(status == DownloadManager.STATUS_SUCCESSFUL){
//Retrieve the saved download id
long downloadID = preferenceManager.getLong(Download_ID, 0);
ParcelFileDescriptor file;
try {
file = downloadManager.openDownloadedFile(downloadID);
Toast.makeText(MainActivity.this,
"File Downloaded: " + file.toString(),
Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(MainActivity.this,
e.toString(),
Toast.LENGTH_LONG).show();
}
}else if(status == DownloadManager.STATUS_FAILED){
Toast.makeText(MainActivity.this,
"FAILED!\n" + "reason of " + reason,
Toast.LENGTH_LONG).show();
}else if(status == DownloadManager.STATUS_PAUSED){
Toast.makeText(MainActivity.this,
"PAUSED!\n" + "reason of " + reason,
Toast.LENGTH_LONG).show();
}else if(status == DownloadManager.STATUS_PENDING){
Toast.makeText(MainActivity.this,
"PENDING!",
Toast.LENGTH_LONG).show();
}else if(status == DownloadManager.STATUS_RUNNING){
Toast.makeText(MainActivity.this,
"RUNNING!",
Toast.LENGTH_LONG).show();
}
}
}
};
}
Where am I going wrong? What should I do to enable the resume capability of the download?
Quoting from docs,
The download manager will conduct the download in the background, taking care of HTTP interactions and retrying downloads after failures or across connectivity changes and system reboots.
I guess Download Manager, by default takes cares of retries.
If you are having issues you can use DownloadManager.Query class and query for COLUMN_STATUS and COLUMN_REASON to get the download status
Edit:
Starting a download
dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
Request request = new Request( YOUR_DOWNLOAD_URL );
long enqueue = dm.enqueue(request);
enqueue is more like a download reqeust id. You can use that enqueue to fetch the download progress/status
Querying the download Status
Query query = new Query();
query.setFilterById(enqueue);
Cursor c = dm.query(query);
if (c.moveToFirst()) {
int downloadStatus = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));
if (DownloadManager.STATUS_SUCCESSFUL == downloadStatus) {
// download succeded
} else if (DownloadManager.STATUS_FAILED == downloadStatus){
String failedReason = c.getString(c.getColumnIndex(DownloadManager.COLUMN_REASON));
// handle failures
}
}
Haven't tested the code myself. But it should work.
I confirm that this problem still exists in 2020, when testing in an emulator and having WiFi enabled, this error consistently appears (even with Android 10).
Switching off WiFi in the emulator seems to solve the problem.
Try to get the reason for the failed download.
e.g does it work on network switch wifi->data
(If your error reason is 1008- there seems to be a reported bug here

How know that subject is well documented and I have read a lot on that issue, but I still have the following problem: when I take a picture with my app and click on "validate" button, nothing occur. The aime of what I am doing: passing to onActivityReult function not only the thumbnail, but the "whole" picture taken by the camera.
Here is the listener as defined for the "take a picture" button:
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "CameraTest");
mediaStorageDir.mkdir(); // make sure you got this folder
Log.i("Report",mediaStorageDir.toString());
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_"+ timeStamp + ".jpg");
try
{
//create directories and the file
mediaFile.getParentFile().mkdirs();
mediaFile.createNewFile();
} catch (IOException e) {
Log.e("Report", "create error for file "+mediaFile);
e.printStackTrace();
}
mFileUri = Uri.fromFile(mediaFile);
Log.i("Report","Uri: "+mFileUri);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);// this line causes issue - onActivityResult not called...
startActivityForResult(intent, CAMERA_PIC_REQUEST);
}
});
and here is the onActivityResult method... that is never called (and that is not declared in the onClickListener method):
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("Report", "1");
if (resultCode == Activity.RESULT_OK) {
if (requestCode == CAMERA_PIC_REQUEST) {
try {
String[] projection = {
MediaStore.Images.Thumbnails._ID, // The columns we want
MediaStore.Images.Thumbnails.IMAGE_ID,
MediaStore.Images.Thumbnails.KIND,
MediaStore.Images.Thumbnails.DATA };
String selection = MediaStore.Images.Thumbnails.KIND + "=" +
MediaStore.Images.Thumbnails.MINI_KIND;
String sort = MediaStore.Images.Thumbnails._ID + " DESC";
Cursor myCursor = this.managedQuery(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
projection, selection, null, sort);
Log.d("Report", "3");
long imageId = 0l;
long thumbnailImageId = 0l;
String thumbnailPath = "";
try {
myCursor.moveToFirst();
imageId = myCursor
.getLong(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));
thumbnailImageId = myCursor
.getLong(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));
thumbnailPath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
} finally {
myCursor.close();
}
String[] largeFileProjection = {
MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA };
String largeFileSort = MediaStore.Images.ImageColumns._ID
+ " DESC";
myCursor = this.managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
largeFileProjection, null, null, largeFileSort);
String largeImagePath = "";
try {
myCursor.moveToFirst();
// This will actually give yo uthe file path location of the
// image.
largeImagePath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
mImageCaptureUri = Uri.fromFile(new File(
largeImagePath));
} finally {
// myCursor.close();
}
Uri uriLargeImage = Uri.withAppendedPath(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
String.valueOf(imageId));
Uri uriThumbnailImage = Uri.withAppendedPath(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
String.valueOf(thumbnailImageId));
Bitmap thumbnail = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uriThumbnailImage);
Bitmap image = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uriLargeImage);
But, as said in the title, onActivityResult is not called. Could you please find out why? Because I have tried almost everything I have found on that subject but I should have missed something.
Thanks !
check if you have declared the right permissions in the AndroidManifest.xml
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and be sure the file you want to write into exists:
add this below puc_img = new File(photo,"Puc_Img.jpg");
try
{
//create directories and the file
puc_file.getParentFile().mkdirs();
puc_file.createNewFile();
} catch (IOException e) { }
It's not clear from your code but you could be declaring onActivityResult within your onClickListener. If that's true you need to move it.
Take a look at this answer:
OnActivityResult ()
Ok, to solve that issue, I used some "trick" detailed here:
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "CameraTest");
mediaStorageDir.mkdir(); // make sure you got this folder
Log.i("Report",mediaStorageDir.toString());
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_"+ timeStamp + ".jpg");
try
{
//create directories and the file
mediaFile.getParentFile().mkdirs();
mediaFile.createNewFile();
} catch (IOException e) {
Log.e("Report", "create error for file "+mediaFile);
e.printStackTrace();
}
tmpFilePath = mediaFile.getPath();
mFileUri = Uri.fromFile(mediaFile);
Log.i("Report","Uri: "+mFileUri);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);
startActivityForResult(intent, CAMERA_PIC_REQUEST);
}
});
So then, I am recovering the file stored in the tmpFilePath, by using that method in the onActivityResult function:
Bitmap image = BitmapFactory.decodeFile(this.tmpFilePath);
And... It's working fine. I still have some issues when sending the file to the WS but that very question have been solved by that piece of code. Thanks for the help, you put me on the track :)
i have an app with a gallery of images and i want that the user can save it into his own gallery.
I've created an option menu with a single voice "save" to allow that but the problem is...how can i save the image into the gallery?
this is my code:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.menuFinale:
imgView.setDrawingCacheEnabled(true);
Bitmap bitmap = imgView.getDrawingCache();
File root = Environment.getExternalStorageDirectory();
File file = new File(root.getAbsolutePath()+"/DCIM/Camera/img.jpg");
try
{
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bitmap.compress(CompressFormat.JPEG, 100, ostream);
ostream.close();
}
catch (Exception e)
{
e.printStackTrace();
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
i'm not sure of this part of code:
File root = Environment.getExternalStorageDirectory();
File file = new File(root.getAbsolutePath()+"/DCIM/Camera/img.jpg");
is it correct to save into the gallery?
unfortunately the code doesn't work :(
MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);
The former code will add the image at the end of the gallery. If you want to modify the date so it appears at the beginning or any other metadata, see the code below (Cortesy of S-K, samkirton):

Actually, you can save you picture at any place. If you want to save in a public space, so any other application can access, use this code:
storageDir = new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
),
getAlbumName()
);
The picture doesn't go to the album. To do this, you need to call a scan:
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
You can found more info at https://developer.android.com/training/camera/photobasics.html#TaskGallery
I've tried a lot of things to let this work on Marshmallow and Lollipop.
Finally i ended up moving the saved picture to the DCIM folder (new Google Photo app scan images only if they are inside this folder apparently)
public static File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
.format(System.currentTimeInMillis());
File storageDir = new File(Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + "/Camera/");
if (!storageDir.exists())
storageDir.mkdirs();
File image = File.createTempFile(
timeStamp, /* prefix */
".jpeg", /* suffix */
storageDir /* directory */
);
return image;
}
And then the standard code for scanning files which you can find in the Google Developers site too.
public static void addPicToGallery(Context context, String photoPath) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(photoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
context.sendBroadcast(mediaScanIntent);
}
Please remember that this folder could not be present in every device in the world and that starting from Marshmallow (API 23), you need to request the permission to WRITE_EXTERNAL_STORAGE to the user.
According to this course, the correct way to do this is:
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
)
This will give you the root path for the gallery directory.
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
You can create a directory inside the camera folder and save the image. After that, you can simply perform your scan. It will instantly show your image in the gallery.
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM).toString()+ "/Camera/Your_Directory_Name";
File myDir = new File(root);
myDir.mkdirs();
String fname = "Image-" + image_name + ".png";
File file = new File(myDir, fname);
System.out.println(file.getAbsolutePath());
if (file.exists()) file.delete();
Log.i("LOAD", root + fname);
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
MediaScannerConnection.scanFile(context, new String[]{file.getPath()}, new String[]{"image/jpeg"}, null);
Here's what worked for me:
private fun saveBitmapAsImageToDevice(bitmap: Bitmap?) {
// Add a specific media item.
val resolver = this.contentResolver
val imageStorageAddress = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY)
} else {
MediaStore.Images.Media.EXTERNAL_CONTENT_URI

put(MediaStore.Images.Media.DISPLAY_NAME, "my_app_${System.currentTimeMillis()}.jpg")
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpeg")
put(MediaStore.MediaColumns.DATE_ADDED, System.currentTimeMillis())
}
try {
// Save the image.
val contentUri: Uri? = resolver.insert(imageStorageAddress, imageDetails)
contentUri?.let { uri ->
// Don't leave an orphan entry in the MediaStore
if (bitmap == null) resolver.delete(contentUri, null, null)
val outputStream: OutputStream? = resolver.openOutputStream(uri)
outputStream?.let { outStream ->
val isBitmapCompressed =
bitmap?.compress(Bitmap.CompressFormat.JPEG, 95, outStream)
if (isBitmapCompressed == true) {
outStream.flush()
outStream.close()
}
} ?: throw IOException("Failed to get output stream.")
} ?: throw IOException("Failed to create new MediaStore record.")
} catch (e: IOException) {
throw e
}
}
Note: For Build.VERSION.SDK_INT < 29, the image has to be saved locally on disk first, which will increase the app size as the user saves more images. The user can delete the image later, in the Files app, but the local image has to sync with Google Photos or Amazon Photos in the cloud.
Saving the image to the cloud is accomplished by having the user open their Google Photos or Amazon Photos app after exporting and before deleting your app APK. If the user of < 29 deletes your APK before opening Google Photos or Amazon Photos, the photo will be lost.
This is a bug with Android Builds before Q (Level 29). Level 29 and later save directly to the Photo Library.

I come here with the same doubt but for Xamarin for Android, I have used the Sigrist answer to do this method after save my file:
private void UpdateGallery()
{
Intent mediaScanIntent = new Intent(Intent.ActionMediaScannerScanFile);
Java.IO.File file = new Java.IO.File(_path);
Android.Net.Uri contentUri = Android.Net.Uri.FromFile(file);
mediaScanIntent.SetData(contentUri);
Application.Context.SendBroadcast(mediaScanIntent);
}
and it solved my problem, Thx Sigrist. I put it here becouse i did not found an answare about this for Xamarin and i hope it can help other people.
In my case the solutions above did not work I had to do the following:
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(f)));
String filePath="/storage/emulated/0/DCIM"+app_name;
File dir=new File(filePath);
if(!dir.exists()){
dir.mkdir();
}
This code is in onCreate method.This code is for creating a directory of app_name.
Now,this directory can be accessed using default file manager app in android.
Use this string filePath wherever required to set your destination folder.
I am sure this method works on Android 7 too because I tested on it.Hence,it can work on other versions of android too.
Just you need to scan your Media After Saving finished.

MediaScannerConnection.scanFile(GenerateQRCodeActivity.this,new String[]{file.getPath()},new String[] {"image/jpeg"},null);
These code are same as everyone .If you try the bellow code after this it will work. You just need these one line of code:
MediaScannerConnection.scanFile(GenerateQRCodeActivity.this,new String[]{file.getPath()},new String[] {"image/jpeg"},null);
Boom!!! Yo can now get your saved image on your Gallery.
I'm working on an Android application that allows users to long-click on a button to save a sound as a ringtone. I am using the code below to do so. The code currently works to save the file in the list of ringtones to be used, however it does not automatically set the sound as the default ringtone. I have searched all around and not had much luck finding a clear guide on saving a sound as the default/active ringtone.
As of now, the user can long-click the button, then go into the Menu > Sounds > Phone Ringtone menu and select from the list, but that seems a bit inconvenient when I know that it is possible to have it simply set as the active ringtone straight away.
Any insight as to what I am missing? Much appreciated!

Not sure if you figured this one out, but I just did recently. Replace your Insert Database line with this:
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" + k.getAbsolutePath() + "\"", null);
Uri newUri = getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(
YOURACTIVITYNAME.this,
RingtoneManager.TYPE_RINGTONE,
newUri
);
