Xamarin Android Sharing Intent under Marshmallow - android

In my Application I try to share an Image with the Intent (Intent.ActionSend).
For the guaranteed Access I use a Fileprovider which creates the Uri to the file.
Under Android Nougat my code works but with Marshmallow not. It shows no errors but the Image is not sent to the recieving App.
The Output from VisualStudio also shows no errors or somthing like that.
I couldn't find any answer online so far. What is the problem with Marshmallow?
public void SendPhoto(IEnumerable<string> photos, string text)
{
var files = new List<Android.Net.Uri>();
//creates for every photo an own ContentURI
foreach (var path in photos)
{
var file = new Java.IO.File(path);
files.Add(FileProvider.GetUriForFile(Context, "com.testapp.fileprovider", file));
}
//Checks if Photolist are empty
if (!files.Any())
throw new Exception("Photos not found");
Intent intent = new Intent(Intent.ActionSend);
intent.SetFlags(ActivityFlags.GrantReadUriPermission);
intent.SetType("image/jpeg");
intent.PutExtra(Intent.ExtraSubject, "Subject");
intent.PutExtra(Intent.ExtraStream, files.First());
//creates the sharemessage
var shareMessage = files.Count == 1 ? "Send photo from TestApp" : "Send photos from TestApp";
//start Intent chooser
Context.StartActivity(Intent.CreateChooser(intent, shareMessage));
}

Android Intent to open instagram posting view

How to open Instagram app in posting mode (so the same view we get after clicking plus at home screen within Instagram app)? I've seen android apps which are doing that, however wasn't able to find information explaing how to achieve it.
That code works for opening the home view:
Uri uri = Uri.parse("http://instagram.com/");
Intent likeIng = new Intent(Intent.ACTION_VIEW, uri);
likeIng.setPackage("com.instagram.android");
startActivity(likeIng);
Perhaps there is some other uri which could work?
After a bit of research it turned out that deep linking with 'instagram://share' opens the desired view.
You can do that only when you have a media to share on Instagram:
try {
String type = "image/*";
String filename = "/myPhoto.jpg";
String mediaPath = Environment.getExternalStorageDirectory() + filename;
Intent share = new Intent(Intent.ACTION_SEND);
share.setPackage("com.instagram.android");
share.setType(type);
File media = new File(mediaPath);
Uri uri = null;
share.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(share);
} catch (Exception e) {
e.printStackTrace();
}
You can create a fake media though to be able to use this method.
Just to expand on #Paavo answer to show the answer in code.
Uri uri = Uri.parse("instagram://share");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.setPackage("com.instagram.android");
//Check that the user can open the intent, meaning they have the Instagram app installed
if (getPackageManager().resolveActivity(intent, 0) != null)
startActivity(intent);
else //User doesn't have app installed, handle however you want
throw new Resources.NotFoundException();

Posting Multiple Images to Instagram using Intents

Instagram allows a single image or video to be uploaded programmatically from an Android app via Android Intents. I have been able to do this successfully. What I want to know is it possible for Instagram to handle multiple images using Intents? Not much to no information on this unfortunately. The following is my last attempt which opens Instagram briefly then closes with a toast message saying "Unable to load image".
Have tried both Intent.ACTION_SEND and Intent.ACTION_SEND_MULTIPLE
val fileUris = ArrayList<Uri>()
val newFile = File("/data/user/0/com.myapp.android/files/media/961087022.jpg")
val contentUri = getUriForFile(this, "com.myapp.fileprovider", newFile)
grantUriPermission("com.instagram.android", contentUri, FLAG_GRANT_READ_URI_PERMISSION)
fileUris.add(contentUri)
val newFile2 = File("/data/user/0/com.myapp.android/files/media/961146948.jpg")
val contentUri2 = getUriForFile(this, "com.myapp.fileprovider", newFile2)
grantUriPermission("com.instagram.android", contentUri2, FLAG_GRANT_READ_URI_PERMISSION)
fileUris.add(contentUri2)
val shareIntent = Intent(Intent.ACTION_SEND)
shareIntent.type = "image/*"
shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, fileUris)
shareIntent.`package` = "com.instagram.android"
startActivity(Intent.createChooser(shareIntent, "Share to"))
I was looking on how to share multiple video files to instagram stories.. I couldn't find how to do it reading the facebook documentation.
Instead i set the intent to send multiple files and set the intent package to "com.instagram.android", and surprisingly it worked..
Intent share = new Intent(Intent.ACTION_SEND_MULTIPLE) ;
share.setType("video/*");
share.putExtra(Intent.EXTRA_SUBJECT, "abc");
share.putExtra(Intent.EXTRA_TITLE, "abcd");
ArrayList<Uri> files = new ArrayList<Uri>();
for (String path : filesToSend) {
File myFiles = new File(path);
Uri doneUri = FileProvider.getUriForFile(Objects.requireNonNull(getApplicationContext()),
BuildConfig.APPLICATION_ID + ".provider", myFiles);
files.add(doneUri);
}
share.setPackage("com.instagram.android");
share.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
startActivity(share);
Hope, this helps!!

How to set up share Intent in android.

I want to share multiple images with other application using share action provided by android. The below code does not works as intended.
Sending Activity:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND_MULTIPLE);
//intent.putExtra(Intent.EXTRA_SUBJECT, "Here are some files.");
intent.setType("image/*");
ArrayList<Uri> files = new ArrayList<Uri>();
for (String path : imageArray) {
File file = new File(path);
Uri uri = Uri.fromFile(file);
files.add(uri);
}
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
shareAction.setShareIntent(intent);
Receiving activity code:
if (Intent.ACTION_SEND_MULTIPLE.equals(intent.getAction())
&& intent.hasExtra(Intent.EXTRA_STREAM)) {
ArrayList<Parcelable> list =
intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
for (Parcelable p : list) {
Uri uri = (Uri) p;
System.out.println("hello world");
}
}
Receiving activity output :
file:///absolute-path-to-file
I want output in content://absolute-path-to-file format. Because i am getting this format when receiving file intent from other applications.
Other possible way to solve this is also recommended.

Android: How to open a specific folder via Intent and show its content in a file browser?

I thought this would be easy but as it turns out unfortunately it's not.
What I have:
I have a folder called "myFolder" on my external storage (not sd card because it's a Nexus 4, but that should not be the problem). The folder contains some *.csv files.
What I want:
I want to write a method which does the following: Show a variety of apps (file browsers) from which I can pick one (see picture). After I click on it, the selected file browser should start and show me the content of "myFolder". No more no less.
My question:
How exactly do I do that? I think I came quite close with the following code, but no matter what I do - and I'm certain that there must be something I didn't get right yet - it always opens only the main folder from the external storage.
public void openFolder()
{
File file = new File(Environment.getExternalStorageDirectory(),
"myFolder");
Log.d("path", file.toString());
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setDataAndType(Uri.fromFile(file), "*/*");
startActivity(intent);
}
This should help you:
Uri selectedUri = Uri.parse(Environment.getExternalStorageDirectory() + "/myFolder/");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(selectedUri, "resource/folder");
if (intent.resolveActivityInfo(getPackageManager(), 0) != null)
{
startActivity(intent);
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
}
Please, be sure that you have any file explorer app installed on your device.
EDIT: added a shantanu's recommendation from the comment.
LIBRARIES:
You can also have a look at the following libraries https://android-arsenal.com/tag/35 if the current solution doesn't help you.
I finally got it working. This way only a few apps are shown by the chooser (Google Drive, Dropbox, Root Explorer, and Solid Explorer). It's working fine with the two explorers but not with Google Drive and Dropbox (I guess because they cannot access the external storage). The other MIME type like "*/*" is also possible.
public void openFolder(){
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ File.separator + "myFolder" + File.separator);
intent.setDataAndType(uri, "text/csv");
startActivity(Intent.createChooser(intent, "Open folder"));
}
Here is my answer
private fun openFolder() {
val location = "/storage/emulated/0/Download/";
val intent = Intent(Intent.ACTION_VIEW)
val myDir: Uri = FileProvider.getUriForFile(context, context.applicationContext.packageName + ".provider", File(location))
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
intent.setDataAndType(myDir, DocumentsContract.Document.MIME_TYPE_DIR)
else intent.setDataAndType(myDir, "*/*")
if (intent.resolveActivityInfo(context.packageManager, 0) != null)
{
context.startActivity(intent)
}
else
{
// if you reach this place, it means there is no any file
// explorer app installed on your device
CustomToast.toastIt(context,context.getString(R.string.there_is_no_file_explorer_app_present_text))
}
}
Here why I used FileProvider - android.os.FileUriExposedException: file:///storage/emulated/0/test.txt exposed beyond app through Intent.getData()
I tested on this device
Devices: Samsung SM-G950F (dreamltexx), Os API Level: 28
Intent chooser = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getDownloadCacheDirectory().getPath().toString());
chooser.addCategory(Intent.CATEGORY_OPENABLE);
chooser.setDataAndType(uri, "*/*");
// startActivity(chooser);
try {
startActivityForResult(chooser, SELECT_FILE);
}
catch (android.content.ActivityNotFoundException ex)
{
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
In code above, if setDataAndType is "*/*" a builtin file browser is opened to pick any file, if I set "text/plain" Dropbox is opened. I have Dropbox, Google Drive installed. If I uninstall Dropbox only "*/*" works to open file browser. This is Android 4.4.2. I can download contents from Dropbox and for Google Drive, by getContentResolver().openInputStream(data.getData()).
Thread is old but I needed this kind of feature in my application and I found a way to do it so I decided to post it if it can help anyone in my situation.
As our device fleet is composed only by Samsung Galaxy Tab 2, I just had to find the file explorer's package name, give the right path and I succeed open my file explorer where I wanted to. I wish I could use Intent.CATEGORY_APP_FILES but it is only available in API 29.
Intent intent = context.getPackageManager().getLaunchIntentForPackage("com.sec.android.app.myfiles");
Uri uri = Uri.parse(rootPath);
if (intent != null) {
intent.setData(uri);
startActivity(intent);
}
As I said, it was easy for me because our clients have the same device but it may help others to find a workaround for their own situation.
this code will work with OI File Manager :
File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
Uri uri = Uri.fromFile(root);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(uri);
startActivityForResult(intent, 1);
you can get OI File manager here : http://www.openintents.org/en/filemanager
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, DocumentsContract.Document.MIME_TYPE_DIR);
startActivity(intent);
Will open files app home screen
Today, you should be representing a folder using its content: URI as obtained from the Storage Access Framework, and opening it should be as simple as:
Intent i = new Intent(Intent.ACTION_VIEW, uri);
startActivity(i);
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("text/csv");
intent.addCategory(Intent.CATEGORY_OPENABLE);
try {
startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"), 0);
} catch (android.content.ActivityNotFoundException ex) {
ex.printStackTrace();
}
then you just need to add the response
public void onActivityResult(int requestCode, int resultCode, Intent data){
switch (requestCode) {
case 0: {
//what you want to do
//file = new File(uri.getPath());
}
}
}
You seem close.
I would try to set the URI like this :
String folderPath = Environment.getExternalStorageDirectory()+"/pathTo/folder";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
Uri myUri = Uri.parse(folderPath);
intent.setDataAndType(myUri , "file/*");
startActivity(intent);
But it's not so different from what you have tried.
Tell us if it changes anything ?
Also make sure the targeted folder exists, and have a look on the resulting Uri object before to send it to the intent, it may not be what we are expected.
File temp = File.createTempFile("preview", ".png" );
String fullfileName= temp.getAbsolutePath();
final String fileName = Uri.parse(fullfileName)
.getLastPathSegment();
final String filePath = fullfileName.
substring(0,fullfileName.lastIndexOf(File.separator));
Log.d("filePath", "filePath: " + filePath);
fullfileName:
/mnt/sdcard/Download_Manager_Farsi/preview.png
filePath:
/mnt/sdcard/Download_Manager_Farsi

Using Android ACTION_SEND to send image via Messenger and Facebook

In my app i want to be able to use the ACTION_SEND intent to send a picture saved on my local SD card by either Email, Facebook, or the Messenger(MMS). With the code I have I can sucessfully email the picture as an attachment but when I select Facebook i get the error, "An error occured while loading the photo" and when i try selecting the Messenger it says, "Sorry, You cannot add this picture to your message".
Here is my code:
File pic = new File(Environment.getExternalStorageDirectory()+ File.separator + "images" + File.separator + "picture.jpg");
Uri pngUri = Uri.fromFile(pic);
Intent picMessageIntent = new Intent(android.content.Intent.ACTION_SEND);
picMessageIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
picMessageIntent.setType("image/jpeg");
picMessageIntent.putExtra(Intent.EXTRA_STREAM, pngUri);
startActivity(Intent.createChooser(picMessageIntent, "Send your picture using:"));
Does anyone have any idea what i need to change to make this code work with the Messenger and Facebook?
To send image with MMS, you must get the URI of media provider, URI from file path doesn't work (I met this problem before). For Facebook, I've no idea how to user ACTION_SEND to send image, since I used Facebook SDK to post status and send photo (and that is a much better way since you don't need to rely on phones which have facebook installed before).
protected void sendMMS(final String body, final String imagePath) {
MediaScannerConnectionClient mediaScannerClient = new MediaScannerConnectionClient() {
private MediaScannerConnection msc = null;
{
msc = new MediaScannerConnection(getApplicationContext(), this);
msc.connect();
}
public void onMediaScannerConnected() {
msc.scanFile(imagePath, null);
}
public void onScanCompleted(String path, Uri uri) {
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra("sms_body", body);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
sendIntent.setType("image/png");
startActivity(sendIntent);
msc.disconnect();
}
};
}
