I am downloading photos to smartphone. For versions lower than Oreo, there's no problem. But for Oreo, my code isn't not working. I tried this code in Emulator:
I implemented a function to save an image to external storage.
private void saveImageToExternalStorage(Bitmap finalBitmap,String name) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/xx");
myDir.mkdirs();
String fname = name + ".jpg";
File file = new File(myDir, fname);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(this, new String[] { file.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
}
I am requesting permissions with dexter library.
Dexter.withActivity(MainActivity.this)
.withPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)
.withListener(new PermissionListener() {
#Override
public void onPermissionGranted(PermissionGrantedResponse response) {
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(MainActivity.this);
if (!prefs.getBoolean("firstTime", false)) {
task.execute();
SharedPreferences.Editor editor = prefs.edit();
editor.putBoolean("firstTime", true);
editor.commit();
}
}
#Override
public void onPermissionDenied(PermissionDeniedResponse response) {
Toast.makeText(MainActivity.this, "You need to allow permission if you want to use camera", Toast.LENGTH_LONG).show();
}
#Override
public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
token.continuePermissionRequest();
Toast.makeText(MainActivity.this, "You need to allow permission if you want to use camera", Toast.LENGTH_LONG).show();
}
}).check();
I save images with asynctask
final AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>() {
private ProgressDialog dialog;
#Override
protected void onPreExecute()
{
this.dialog = new ProgressDialog(MainActivity.this);
this.dialog.setMessage(getString(R.string.newfeature));
this.dialog.setCancelable(false);
this.dialog.setOnCancelListener(new DialogInterface.OnCancelListener()
{
#Override
public void onCancel(DialogInterface dialog)
{
// cancel AsyncTask
cancel(false);
}
});
this.dialog.show();
}
#Override
protected Void doInBackground(Void... params)
{
// do your stuff
Bitmap myBitmap2 = BitmapFactory.decodeResource(getApplicationContext().getResources(), R.drawable.im2);
saveImageToExternalStorage(myBitmap2,"imag2");
myBitmap2.recycle();
return null;
}
#Override
protected void onPostExecute(Void result)
{
//called on ui thread
if (this.dialog != null) {
this.dialog.dismiss();
}
}
#Override
protected void onCancelled()
{
//called on ui thread
if (this.dialog != null) {
this.dialog.dismiss();
}
}
};
I can see Storage permission is granted when I look Settings --> Apps for my app. But images are not saved correctly. In fact images are saved but all of them is green square like this.
As a result, it gives permission denied error although permission is granted.

Access Sd-Card's files
Use DOCUMENT_TREE dialog to get sd-card's Uri.
Inform user about how to choose sd-card on the dialog. (with pictures or gif animations)
// call for document tree dialog
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
startActivityForResult(intent, REQUEST_CODE_OPEN_DOCUMENT_TREE);
On onActivityResult you'll have the selected directory Uri. (sdCardUri)
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQUEST_CODE_OPEN_DOCUMENT_TREE:
if (resultCode == Activity.RESULT_OK) {
sdCardUri = data.getData();
}
break;
}
}
Now must check if the user,
a. selected the sd-card
b. selected the sd-card that our file is on (some devices could have multiple sd-cards).
We check both a and b by finding the file through the hierarchy, from sd root to our file. If file found, both of a and b conditions are acquired.
//First we get `DocumentFile` from the `TreeUri` which in our case is `sdCardUri`.
DocumentFile documentFile = DocumentFile.fromTreeUri(this, sdCardUri);
//Then we split file path into array of strings.
//ex: parts:{"", "storage", "extSdCard", "MyFolder", "MyFolder", "myImage.jpg"}
// There is a reason for having two similar names "MyFolder" in
//my exmple file path to show you similarity in names in a path will not
//distract our hiarchy search that is provided below.
String[] parts = (file.getPath()).split("\\/");
// findFile method will search documentFile for the first file
// with the expected `DisplayName`
// We skip first three items because we are already on it.(sdCardUri = /storage/extSdCard)
for (int i = 3; i < parts.length; i++) {
if (documentFile != null) {
documentFile = documentFile.findFile(parts[i]);
}
}
if (documentFile == null) {
// File not found on tree search
// User selected a wrong directory as the sd-card
// Here must inform user about how to get the correct sd-card
// and invoke file chooser dialog again.
} else {
// File found on sd-card and it is a correct sd-card directory
// save this path as a root for sd-card on your database(SQLite, XML, txt,...)
// Now do whatever you like to do with documentFile.
// Here I do deletion to provide an example.
if (documentFile.delete()) {// if delete file succeed
// Remove information related to your media from ContentResolver,
// which documentFile.delete() didn't do the trick for me.
// Must do it otherwise you will end up with showing an empty
// ImageView if you are getting your URLs from MediaStore.
//
Uri mediaContentUri = ContentUris.withAppendedId(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
longMediaId);
getContentResolver().delete(mediaContentUri , null, null);
}
}
Note:
You must provide access permission to the external storage inside your manifest and for os>=Marshmallow inside the app.

Edit Sd-Card's Files
For editing an existing image on your sd-card you don't need any of above steps if you want to invoke another app to do it for you.
Here we invoke all the activities (from all the installed apps) with the capability of editing the images. (Programmers mark their apps in the manifest for its capabilities to provide accessibility from other apps (activities)).
on your editButton click event:
String mimeType = getMimeTypeFromMediaContentUri(mediaContentUri);
startActivityForResult(Intent.createChooser(new Intent(Intent.ACTION_EDIT).setDataAndType(mediaContentUri, mimeType).putExtra(Intent.EXTRA_STREAM, mediaContentUri).addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION), "Edit"), REQUEST_CODE_SHARE_EDIT_SET_AS_INTENT);
and this is how to get mimeType:
public String getMimeTypeFromMediaContentUri(Uri uri) {
String mimeType;
if (uri.getScheme().equals(ContentResolver.SCHEME_CONTENT)) {
ContentResolver cr = getContentResolver();
mimeType = cr.getType(uri);
} else {
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
.toString());
mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
fileExtension.toLowerCase());
}
return mimeType;
}
Note:
On Android KitKat(4.4) don't ask the user to select the sd-card because on this version of Android DocumentProvideris not applicable, hence we have no chance to have access to the sd-card with this approach.
Look at the API level for the DocumentProvider
https://developer.android.com/reference/android/provider/DocumentsProvider.html
I couldn't find anything that works on Android KitKat(4.4). If you found anything useful with KitKat please share with us.
On versions below the KitKat access to sd-card is already provided by the OS.

I've searched through a lot of similar cases in stack overflow, but none really helped.
I included necessary permissions and set requestLegacyExternalStorage to true:

As I was searching for a solution, I was wondering if the cause of this error is because I own a Galaxy s21+, which does not have an external storage, and I'm trying to save the recorded file into external storage directory. If so, would there be a solution to my situation? (i.e. saving to an internal storage?). Or, is there something else that I'm doing wrong?
Thank you in advance for your support!
First of all, when Android references "External Storage", it doesn't refer to an SD card. From this link:
"Categories of storage locations
Android provides two types of physical storage locations: internal storage and external storage. On most devices, internal storage is smaller than external storage. However, internal storage is always available on all devices, making it a more reliable place to put data on which your app depends."
The File Not Found could be related to two issues:
You do not have the correct permissions
The folder or file doesn't exist
If you review the error in your Logcat, you can usually determine the specific details. Also, using a File app on your device, you should be able to see if file with that name actually does in that folder.
Double-check to ensure that the permissions have been granted/accepted.
What level SDK are you targeting? If you have targetSdkVersion 30 in your app's build.gradle file, you need to update your code to adhere to a recent policy change that Google made.
If you aren't sure if the directory exists, you can use code such as this to create it:
final File root = new File(String.valueOf(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)));
// Create the directory if it doesn't exist
if (!root.exists()) {
boolean wasSuccessful = root.mkdirs();
// Display Toast message if the directory creation wasn't successful
if (!wasSuccessful) {
mToast = Toast.makeText(this, R.string.photo_directory_not_created_error, Toast.LENGTH_SHORT);
mToast.show();
}
}
So, I have to get GPS data from file MetaData. "No problem", I said, "This will only take an hour or two". Six hour later, here I am searching through all Android Documentation and Stack exchange questions I can yet I still cant get it to work.
My Code is straight forward:
I am using a ACTION_PICK to select a video (ACTION_OPEN_DOCUMENT Doesn't work either).
I Have already requested the following permissions and added to the Manifest:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION" />
Below is code from the button listener
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK , MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
//intent.setType("video/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
startActivityForResult(Intent.createChooser(intent,"Select A Video"),REQUEST_VIDEO_CONTENT);
}
});
And From the OnActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent vIntent) {
super.onActivityResult(requestCode, resultCode, vIntent);
if ((requestCode == REQUEST_VIDEO_CAPTURE || requestCode == REQUEST_VIDEO_CONTENT) && resultCode == RESULT_OK) {
//Attempt to get Content Data
vIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
vIntent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
Uri vUri = vIntent.getData();
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q) {
vUri = MediaStore.setRequireOriginal(vUri);
}
try {
InputStream vIS = getContentResolver().openInputStream(vUri);
ExifInterface vExif = new ExifInterface(vIS);
} catch (SecurityException | IOException e) {
e.printStackTrace();
}
And finally, the lovely SecurityException:

I get that the Error is saying the provider needs to be exported, or grantUriPermission which sounds like an easy fix, except I cannot find a way to implement what they ask. All the places I have looked have suggested adding flags.. as you can see it didnt work.
Please Help :-(
I make an chat app for practice and
tried to use my add1.png image in my drawable folder as a default profile image whether user put the image or not
here's my code snipet
if (imageUri == null) { //when user has no image
//use default image as a profile image that in drawable folder
imageUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE +
"://" + getResources().getResourcePackageName(R.drawable.add1)
+ '/' + getResources().getResourceTypeName(R.drawable.add1)
+ '/' + getResources().getResourceEntryName(R.drawable.add1));
}
//insert into firebase storage
FirebaseStorage.getInstance().getReference().child("userImages").child(uid).putFile(imageUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {...}
In the event that run the app exception has occurred but the default image(add1.png) be inserted into firebase storage properly.
here's the exception.
W/UploadTask: could not retrieve file size for upload android.resource://com.example.harag.myapplication/drawable/add1

thank you!
You need to use UploadTask.UploadTask which you can use to manage and monitor the status of the upload.
Uri file = Uri.fromFile(new File("path/to/images/rivers.jpg"));
StorageReference riversRef = storageRef.child("images/"+file.getLastPathSegment());
uploadTask = riversRef.putFile(file);
// Register observers to listen for when the download is done or if it fails
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.
Uri downloadUrl = taskSnapshot.getDownloadUrl();
}
});
Firebase Upload Files
You can try below code.
Uri uri = Uri.parse("android.resource://org.xyz.abc/drawable/myimage");
or
Uri uri=Uri.parse("android.resource://"+context.getPackageName()+"/drawable/myimage");
I am very sorry if this may be a question with a simple solution.
What Am I Trying To Do?
Capture an image from a Button
Upload that image to Firebase storage
Retrieve that image in an ImageView
What Is My Trouble So Far?
Takes picture, but crashes when I click the tick.
Hence nothing is being uploaded or being achieved.
My Code
P.N I have looked at lots of other forums and video tutorials but nothing seems to be working. Hopefully someone can help.
public class LeaderboardActivity extends AppCompatActivity {
private static final int CAMERA_REQUEST_CODE = 1;
private static final int REQUEST_TAKE_PHOTO = 1;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_leaderboard);
mStorage = FirebaseStorage.getInstance().getReference();
final Button bImage = (Button) findViewById(R.id.bCamera);
final ImageView ivPic = (ImageView) findViewById(R.id.ivPic);
mProgress = new ProgressDialog(this);

I have looked at other people who had the same problem, followed what they said nothing happend, followed the Google Android instructions for this and again same problem.
On button, click remove that intent and just call your
dispatchTakePictureIntetnt() method on Onclick button Listener
Also, check go to your emulator settings, and check your camera
permission is on for your this app and also go to firebase console
and check the rules if, rules are not equal to null made them equal
to null then run your app because !=null rules only work when there
is an authentication method in your app
