无法使用getFileDir将图像保存到Android中的照片/图库

Question

我有以下代码，并希望将数据保存在内部存储中，如照片/图库，但无法使用以下代码。如何将数据保存到内部存储？一些样品或提示会很棒！期待您的来信！

我正在使用当前代码来保存数据。

@SuppressLint("MissingPermission")
    private void saveImage() {
        if (requestPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
            showLoading("Saving...");
            File file = new File(getBaseContext().getFilesDir()
                    + File.separator + ""
                    + System.currentTimeMillis() + ".png");
            try {
                file.createNewFile();

                SaveSettings saveSettings = new SaveSettings.Builder()
                        .setClearViewsEnabled(true)
                        .setTransparencyEnabled(true)
                        .build();

                mPhotoEditor.saveAsFile(file.getAbsolutePath(), saveSettings, new PhotoEditor.OnSaveListener() {
                    @Override
                    public void onSuccess(@NonNull String imagePath) {
                        hideLoading();
                        showSnackbar("Image Saved Successfully");
                        mPhotoEditorView.getSource().setImageURI(Uri.fromFile(new File(imagePath)));
                    }

                    @Override
                    public void onFailure(@NonNull Exception exception) {
                        hideLoading();
                        showSnackbar("Failed to save Image");
                    }
                });
            } catch (IOException e) {
                e.printStackTrace();
                hideLoading();
                showSnackbar(e.getMessage());
            }
        }
    }

private void saveImage() {

        if (requestPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
            showLoading("Saving...");

            filename = String.valueOf(System.currentTimeMillis()) + ".png";
            File file = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "/" + getResources().getString(R.string.app_name));

            try {
                if (!file.exists())
                    file.mkdir();

                file.createNewFile();
                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                    // TODO: Consider calling
                    //    ActivityCompat#requestPermissions
                    // here to request the missing permissions, and then overriding
                    // public void onRequestPermissionsResult(int requestCode, String[] permissions,
                    //                                          int[] grantResults)
                    // to handle the case where the user grants the permission. See the documentation
                    // for ActivityCompat#requestPermissions for more details.
                    return;
                }
