Select multiple files with Intent.ACTION_GET_CONTENT

I'm trying to select multiple files with an Intent, but it seems like I'm missing on something.
I create an Intent.ACTION_GET_CONTENT Intent, put Intent.EXTRA_ALLOW_MULTIPLE as extra in
(it seems to perfectly fit the purpose) and create a chooser (optional), which chooses the application that should be able to pick multiple files and return them.

The Problem is that I can only pick a single file.

I tried multiple file explorers. It's API 18 (4.3). 

ACTIVITY_CHOOSE_FILE = 1;  //global constant
Button btn = (Button) this.findViewById(R.id.btnGetFiles);
btn.setOnClickListener(new OnClickListener() {
  @Override  
  public void onClick(View v) {  
    Intent chooseFile;  
    Intent intent;  
    chooseFile = new Intent(Intent.ACTION_GET_CONTENT);  
    chooseFile.setType("file/*");  
    chooseFile.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);  
    intent = Intent.createChooser(chooseFile, "Choose a file");  
    startActivityForResult(intent, ACTIVITY_CHOOSE_FILE);  
  }  
});

I also added this to the Manifest (it had the same functionality before adding it):

        <intent-filter>
            <action android:name="android.intent.action.GET_CONTENT" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>

Why can't I choose multiple files?
(For clarification: the problem is not, that multiple files aren't returned - I can't choose more than 1 file)

I got the same issue and ACTION_OPEN_DOCUMENT worked for me.

public void selectImages() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.putExtra(DocumentsContract.EXTRA_INITIAL_URI, your_initial_uri);
    intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
    intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
    startActivityForResult(intent, 1);
}

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1) {
        if(resultCode == RESULT_OK) {
// also check data.data because if the user select one file the file and uri will be in  data.data and data.getClipData() will be null
            for(int i = 0; i < data.getClipData().getItemCount(); i++) {
                Uri uri = data.getClipData().getItemAt(i).getUri();
                System.out.println("image" + i + "=" + uri.toString());                
             }
        }
   }
}

Here's the solution in my case it worked for me and allows me to select any kind of file(s).

// Start intent from your method
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setType("*/*");
startActivityForResult(intent, 1001);

// Get the result from this Overriden method
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {    
    if (resultCode == RESULT_OK) {
        switch (requestCode) {
            case 1001:

                // Checking whether data is null or not
                if (data != null) { 

                    // Checking for selection multiple files or single.
                    if (data.getClipData() != null){    

                        // Getting the length of data and logging up the logs using index
                        for (int index = 0; index < data.getClipData().getItemCount(); index++) {   

                            // Getting the URIs of the selected files and logging them into logcat at debug level
                            Uri uri = data.getClipData().getItemAt(index).getUri();
                            Log.d("filesUri [" + uri + "] : ", String.valueOf(uri) );
                        }
                    }else{ 

                        // Getting the URI of the selected file and logging into logcat at debug level
                        Uri uri = data.getData();
                        Log.d("fileUri: ", String.valueOf(uri));
                    }
                }
                break;
        }
    }
}

I know it's a bit outdated post but still if someone encounters it: in this sample, we open default system file explorer to allow a user select multiple files of any type on his device:

Intent filesIntent;
filesIntent = new Intent(Intent.ACTION_GET_CONTENT);
filesIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
filesIntent.addCategory(Intent.CATEGORY_OPENABLE);
filesIntent.setType("*/*");  //use image/* for photos, etc.
startActivityForResult(filesIntent, REQUEST_CODE_FOR_ON_ACTIVITY_RESULT);

I got same issue. Here my solution.

Java:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data)
    if(requestCode == PICKFILE_RESULT_CODE) {
       if(null != data) { // checking empty selection
          if(null != data.getClipData()) { // checking multiple selection or not
             for(int i = 0; i < data.getClipData().getItemCount(); i++) {
                Uri uri = data.getClipData().getItemAt(i).getUri();
             }
          } else {
             Uri uri = data.getData();
          }
       }
    }
 }

Kotlin:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
        super.onActivityResult(requestCode, resultCode, data)
        when (requestCode) {
            PICKFILE_RESULT_CODE -> if (resultCode === Activity.RESULT_OK) {
                if (null != data) {
                    if (null !=data.clipData) {
                        for (i in 0 until data.clipData.itemCount) {
                            val uri = data.clipData.getItemAt(i).uri
                            dumpImageMetaData(uri)
                        }
                    } else {
                        val uri = data.data
                        dumpImageMetaData(uri)
                    }
                }
            }
        }
    }

Why can't I choose multiple files?

Presumably, the implemeters of "the application that should be able to pick multiple files and return them" have not implemented EXTRA_ALLOW_MULTIPLE support. Contact them and request this feature.
