Android Custom FileChooser - android

In my app the user has the opportunity to import a file via an intent.
Intent chooseFile = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(new Helper(FunctionsActivity.this).getPathToAppFolder());
chooseFile.setDataAndType(uri, "*/*");
chooseFile.setType("*/*");
Intent intent = Intent.createChooser(chooseFile, getString(R.string.importDatei));
startActivityForResult(intent, REQUEST_CODE_IMPORT_FILE);
The valid files are files with the ending: .tr
These can undestood by my app.
The problem is, that the Intent shows all files in the folder:
After long searching I could not find a solution to show only .tr files. (Besides: For .xml or known file formats it is possible.)
So my idea is to write a small custom filechooser. When you click on "import", an activity opens that shows the names of all files with the extension .tr
So my question is:
Has anyone implemented something like this and can help me or does anyone has tips how to implement this the best?
I am grateful for everything that helps me further

Create File Explorer for PDF, Text and Image in Android

I am new in android development and I just want to know how to do a customized file explorer that will only display pdf, text and image files.
I tried this example but I dont know how to filter the files that can be displayed :(
Android File Explore
Is there a way to display and select only the files mentioned above?

Take a look at #Smitted answer.
Create the intent:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
You can set the MIME types for the intent:
intent.SetType("application/pdf");
and add additional MIME types:
String[] mimetypes = {"image/*", "text/*"};
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
and start the activity:
StartActivityForResult(intent, FIND_FILE_REQUEST_CODE);

You can filter the files in the accept() of new FilenameFilter().

Android Studio - Open epub + pdf files from default directory application (Programmatically)

How to open default file manager app that let you choose a file but only with extension .epub or .pdf programatically via Intent?

The code shown is the declaration of the intent that you have to start for opening the default file manager app that let you choose a file but only with extension .epub or .pdf, I hope it will be useful.
Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("application/epub+zip");
String[] mimetypes = {"application/epub+zip", "application/pdf"};
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
startActivityForResult(intent,PICKFILE_RESULT_CODE);
It is a mix of solutions I found that work so maybe it is redundant. Let me know what you think!

How to open the My Files folder in Android Programatically (using Intent)?

I am using the below code which opens up the Gallery, Music Player, Dropbox and Contacts, i want the My Files folder to get open programatically, please let me know if there are any specific intent parameters i need to pass to get the File Manager open.
if it is not possible through intent then please give me a snippet or an hint to open the My Files folder programatically.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
Intent i = Intent.createChooser(intent, "View Default File Manager");
startActivityForResult(i, CHOOSE_FILE_REQUESTCODE);
Thanks.

You can use this code to file the files.
int PICKFILE_RESULT_CODE=1;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent,PICKFILE_RESULT_CODE);
this will help you to browse the files from your storage.

Its best that you include a library in your project which handles this scenario.
This worked for me:
This library shows the list of third-party apps. It also has its own file browser for selecting files.

Bad thing is, most Android distributions may or may not ship with a file manager, and even so, may be not with the one which handles CHOOSE_FILE_REQUESTCODE.
So, you are left to create your own file picker activity. Luckily there are many ready made ones available:
http://code.google.com/p/android-filechooser/
https://developers.inkfilepicker.com/docs/android/

If you want to open samsung My Files application try this below code.
Intent intent = new Intent("com.sec.android.app.myfiles.PICK_DATA");
intent.putExtra("CONTENT_TYPE", "*/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);

You have to specifically mention the package name of the explorer application. Please find the example below to open a specific folder in ES Explorer.
public void openfolderInexplorer(String path){
Intent intent = this.getPackageManager().getLaunchIntentForPackage("com.estrongs.android.pop");
if (intent != null) {
// If the application is avilable
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Uri uri = Uri.parse(path);
intent.setDataAndType(uri, "resource/folder");
this.startActivity(intent);
} else {
// Play store to install app
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id=" +
"com.estrongs.android.pop"));
this.startActivity(intent);
}

try this below code. if any file manager available , then it will pop up in a form of menu to choose appropriate for the user.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, CHOOSE_FILE_REQUESTCODE);
