In my app, I'm saving my application exported pdf file in SD-CARD/myapp directory. I want to open that directory from my app in any filemanager installed in android device. So that user can easily move that directory easily to get those files exported by my app.
I have tried this code from Android: How to open a specific folder via Intent and show its content in a file browser? (Accepted answer)
private void openDirectory() {
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"));
}
but it's showing me error on startActivity Expected 3 arguments but found 1.
Tried also this code but everywhere it shows startActivity needs 3 arguments but found 1.
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
}
I want to play videos i have stored in the external storage with the phone's standard video Player app. I've tried using FileProvider, but I can't manage to pass the video to the player.
private void passVideo(String videoname){
File videoPath = new File(Environment.getExternalStorageDirectory(), "video_folder");
File newFile = new File(videoPath, videoname);
Uri path = FileProvider.getUriForFile(this, "com.example.provider", newFile);
Intent shareIntent = ShareCompat.IntentBuilder.from(this)
.setType(getContentResolver().getType(path))
.setStream(path)
.getIntent();
shareIntent.setData(path);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(Intent.createChooser(shareIntent, "Open Video..."));
}
With this code I manage to get the Chooser for gmail, whatsapp and other social media platforms, but that's not what I want and they all say they can't handle the file format anyway. It also gives the option to play the video with VLC, but it instantly crashes.
I have tried every possible file format and none of them works.
Sorry if I'm missing something obvious, I am still a beginner.
ShareCompat.IntentBuilder is for ACTION_SEND, which is not the typical Intent action for playing a video. ACTION_VIEW would be more typical. So, try:
private void passVideo(String videoname){
File videoPath = new File(Environment.getExternalStorageDirectory(), "video_folder");
File newFile = new File(videoPath, videoname);
Uri uri = FileProvider.getUriForFile(this, "com.example.provider", newFile);
Intent viewIntent = new Intent(Intent.ACTION_VIEW, uri);
viewIntent.setType(getContentResolver().getType(uri));
viewIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(viewIntent);
}
I'm trying to make a button in my app when user click on it, it'll open a specific URI in file manager but the best I could've done is that the button opens recent tab in default file manager.
Please, if it's possible, suggest me a code which opens a chooser for user to choose between his file manager applications and when user chose, that file manager opens in specific URI that I defined in my code.
Here is my code:
val intent = Intent(Intent.ACTION_GET_CONTENT)
val uri = Uri.parse(
//my path
)
intent.data = uri
intent.type = "*/*"
startActivity(Intent.createChooser(intent, "Open folder"))
Also one of the users suggested me to use INITIAL_URI I've did it like this but didn't work :
val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.addCategory(Intent.CATEGORY_OPENABLE)
val uri = Uri.parse(
//my path
)
intent.data = uri
intent.type = "*/*"
intent.putExtra("android.provider.extra.INITIAL_URI", uri)
intent.putExtra("android.content.extra.SHOW_ADVANCED", true)
startActivity(Intent.createChooser(intent, "Open folder"))
suggest me a code which opens a chooser for user to choose between his file manager applications and when user chose, that file manager opens in specific URI that I defined in my code
That has never been a pattern in Android app development. There is no standard Intent action for what you seek that is likely to be implemented by much of anything, let alone a significant number of file manager apps.
fun openNewTabWindow(urls: String, context : Context) {
val uris = Uri.parse(urls)
val intents = Intent(Intent.ACTION_VIEW, uris)
val myV = Bundle()
myV.putBoolean("new_window", true)
intents.putExtras(myV)
context.startActivity(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!!
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
