ApiException: 1502: Invalid parent folder.

[or-dvir]

first of all i have seen this issue https://github.com/googledrive/android-demos/issues/35 but it does not apply to me since i am not using drive/resource id to create the file.

so here's my problem: i am trying to create a text file inside the app folder and i am getting this error: com.google.android.gms.common.api.ApiException com.google.android.gms.common.api.ApiException: 1502: Invalid parent folder. at com.google.android.gms.internal.zzbsv.onError(Unknown Source) at com.google.android.gms.internal.zzbql.onTransact(Unknown Source) at android.os.Binder.execTransact(Binder.java:565)

first i look for the file in the folder:

final Task<DriveFolder> taskGetAppFolder = getDriveResourceClient().getAppFolder();
        taskGetAppFolder.continueWithTask(new Continuation<DriveFolder, Task<MetadataBuffer>>()
        {
            @Override
            public Task<MetadataBuffer> then(@NonNull Task<DriveFolder> task) throws Exception
            {
                //querying for our file in the app folder of the users' google drive
                Query query = new Query.Builder()
                        .addFilter(Filters.eq(SearchableField.TITLE, Utils.GOOGLE_DRIVE_FILE_NAME))
                        .addFilter(Filters.eq(SearchableField.MIME_TYPE, "text/plain"))
                        .build();

                return getDriveResourceClient().queryChildren(task.getResult(), query);
            }
        }).continueWith(new Continuation<MetadataBuffer, Void>()
        {
            @Override
            public Void then(@NonNull Task<MetadataBuffer> task) throws Exception
            {
                boolean isReadingFileFromDrive = false;
                EventReadUserFavoriteShows driveEvent = new EventReadUserFavoriteShows();

                //file does not exist in google drive
                if (task.getResult().getCount() == 0)
                {
                    createGoogleDriveFile(taskGetAppFolder.getResult());
                }

                                //some more code

and here is the creation of the file:

private void createGoogleDriveFile(final DriveFolder appFolder)
    {
        MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                .setTitle(Utils.GOOGLE_DRIVE_FILE_NAME)
                .setMimeType("text/plain")
                .build();

        //when DriveContents is null, it just created an empty file
        Task<DriveFile> taskCreateFile =
                getDriveResourceClient().createFile(appFolder ,changeSet, null);
        taskCreateFile
                .addOnSuccessListener(BaseActivity.this, new OnSuccessListener<DriveFile>()
                {
                    @Override
                    public void onSuccess(DriveFile driveFile)
                    {
                        //todo save file id for next time?????????????
                        Toast.makeText(BaseActivity.this,
                                       R.string.createGoogleDriveFileSuccess,
                                       Toast.LENGTH_LONG)
                             .show();
                    }
                })
                .addOnFailureListener(BaseActivity.this, new OnFailureListener()
                {
                    @Override
                    public void onFailure(@NonNull Exception e)
                    {
                        Log.e(TAG, e.getClass().getName(), e);
                        Utils.makeSimpleDialog(BaseActivity.this,
                                               R.string.errorTitle,
                                               R.string.errorCreatingGoogleDriveFile,
                                               R.string.ok,
                                               null);
                    }
                });
    }

this has worked in the past but all of a sudden stopped working at all and i receive the above exception. i have tried to remove/disconnect the app from my google drive and also reinstall it on my phone but still getting the exception.
