I have an arrayList with URI's and i want an intent to open it with gallery.

This is what i have now:

public void btnChoosePhotosClick(View v){

    ArrayList<String> selectedItems = imageAdapter.getCheckedItems();
    Toast.makeText(MainActivity.this, "Total photos selected: "+selectedItems.size(), Toast.LENGTH_SHORT).show();
    Log.d(MainActivity.class.getSimpleName(), "Selected Items: " + selectedItems.toString());

    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.parse("file://" + selectedItems), "image/*");
    startActivity(intent);
}

But this just opens empty gallery with the text "no thumbnail"

GetCheckItems()

public ArrayList<String> getCheckedItems() {
        ArrayList<String> mTempArry = new ArrayList<String>();

        for(int i=0;i<mList.size();i++) {
            if(mSparseBooleanArray.get(i)) {
                mTempArry.add(mList.get(i));
            }
        }

        return mTempArry;
    }

Instead of Strings, try to get the Uri

// Instead of Strings, return the Uri of each file.
ArrayList<Uri> selectedItems = imageAdapter.getCheckedItems();

There is a method called: Uri.fromFile(file);

If you manage to pass the files Uri on your imageAdapter.getCheckedItems(); it should work.

Try this on your Intent:

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setType("image/*"); /* All Image Types */
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, selectedItems);
startActivity(intent);

  • Are you getting the files uri? You should pass the files and then use. Uri.getFromFile(file), Instead of Strings, get the all the files URI and pass an ArrayList selectedItems and it should work. – Joaquim Ley Sep 08 '14 at 18:31
