Save picture to storage using Glide
Basing on Akshay Nandwana answer I used that code to write to internal memory:
Glide.with(context)
.asBitmap()
.load(url)
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(Bitmap resource,Transition<? super Bitmap> transition) {
write(fileName, resource);
}
});
And here is the write
method:
public void write(String fileName, Bitmap bitmap) {
FileOutputStream outputStream;
try {
outputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
outputStream.close();
} catch (Exception error) {
error.printStackTrace();
}
}
Update
1.Permissions in manifest file
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
- Need Coroutine to do some background work
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.9'
- Glide to get the image as a bitmap
CoroutineScope(Dispatchers.IO).launch {
saveImage(Glide.with(this@MainActivity)
.asBitmap()
.load("https://i.imgur.com/4HFRb2z.jpg") // sample image
.placeholder(android.R.drawable.progress_indeterminate_horizontal) // need placeholder to avoid issue like glide annotations
.error(android.R.drawable.stat_notify_error) // need error to avoid issue like glide annotations
.submit()
.get())
}
- Save the image in a newly created folder with the specific name
private fun saveImage(image: Bitmap): String? {
var savedImagePath: String? = null
val imageFileName = "JPEG_" + "FILE_NAME" + ".jpg"
val storageDir = File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
.toString() + "/YOUR_FOLDER_NAME"
)
var success = true
if (!storageDir.exists()) {
success = storageDir.mkdirs()
}
if (success) {
val imageFile = File(storageDir, imageFileName)
savedImagePath = imageFile.getAbsolutePath()
try {
val fOut: OutputStream = FileOutputStream(imageFile)
image.compress(Bitmap.CompressFormat.JPEG, 100, fOut)
fOut.close()
} catch (e: Exception) {
e.printStackTrace()
}
// Add the image to the system gallery
galleryAddPic(savedImagePath)
//Toast.makeText(this, "IMAGE SAVED", Toast.LENGTH_LONG).show() // to make this working, need to manage coroutine, as this execution is something off the main thread
}
return savedImagePath
}
- Add the image to the gallery and do send broadcast (not mentioning much about as it's out of the question)
private fun galleryAddPic(imagePath: String?) {
imagePath?.let { path ->
val mediaScanIntent = Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE)
val f = File(path)
val contentUri: Uri = Uri.fromFile(f)
mediaScanIntent.data = contentUri
sendBroadcast(mediaScanIntent)
}
}

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

2.Glide to download the image as a bitmap
Glide.with(mContext)
.load("YOUR_URL")
.asBitmap()
.into(new SimpleTarget<Bitmap>(100,100) {
@Override
public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
saveImage(resource);
}
});
- Save the bitmap into your memory
private String saveImage(Bitmap image) {
String savedImagePath = null;
String imageFileName = "JPEG_" + "FILE_NAME" + ".jpg";
File storageDir = new File( Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
+ "/YOUR_FOLDER_NAME");
boolean success = true;
if (!storageDir.exists()) {
success = storageDir.mkdirs();
}
if (success) {
File imageFile = new File(storageDir, imageFileName);
savedImagePath = imageFile.getAbsolutePath();
try {
OutputStream fOut = new FileOutputStream(imageFile);
image.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.close();
} catch (Exception e) {
e.printStackTrace();
}
// Add the image to the system gallery
galleryAddPic(savedImagePath);
Toast.makeText(mContext, "IMAGE SAVED", Toast.LENGTH_LONG).show();
}
return savedImagePath;
}
private void galleryAddPic(String imagePath) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(imagePath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
}
SimpleTarget<Bitmap>
is now deprecated, use CustomTarget<Bitmap>
, your Glide request now becomes
kotlin
Glide.with(context)
.asBitmap()
.load(url)
.into(object: CustomTarget<Bitmap>() {
override fun onLoadCleared(placeholder: Drawable?) {
}
override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
}
})
Java
Glide.with(context)
.asBitmap()
.load(url)
.into(new CustomTarget<Bitmap>() {
@Override
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
}
@Override
public void onLoadCleared(@Nullable Drawable placeholder) {
}
});
