select, crop, and save the uri an image in shared preferences

Question

this code allows the user to select an image in his gallery and to crop it to put it in an imageview. but every time I leave the application and open it again, the image is no longer there so I would like to save the uri an image cropped by the users in the preference shared so that it is persistent .

Like implementing cele please!

Selection image:

permissionsCheck();
    Intent intent = new Intent();

    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);

    startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_FILE);

crop image:

private void doCrop() {
    final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
    Intent intent = new Intent("com.android.camera.action.CROP");
    intent.setType("image/*");

    List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );

    int size = list.size();
    if (size == 0) {
        Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();

        return;
    } else {
        intent.setData(mImageCaptureUri);

        intent.putExtra("outputX", 100);
        intent.putExtra("outputY", 100);
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        intent.putExtra("scale", false);
        intent.putExtra("return-data", true);

        if (size == 1) {
            Intent i        = new Intent(intent);
            ResolveInfo res = list.get(0);
            i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
            startActivityForResult(i, CROP_FROM_CAMERA);
        } else {
            for (ResolveInfo res : list) {
                final CropOption co = new CropOption();
                co.title    = getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
                co.icon     = getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
                co.appIntent= new Intent(intent);
                co.appIntent.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
                cropOptions.add(co);
            }

            CropOptionAdapter adapter = new CropOptionAdapter(getApplicationContext(), cropOptions);

            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Choose Crop App");
            builder.setAdapter( adapter, new DialogInterface.OnClickListener() {
                public void onClick( DialogInterface dialog, int item ) {
                    startActivityForResult( cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
                }
            });

            builder.setOnCancelListener( new DialogInterface.OnCancelListener() {
                @Override
                public void onCancel( DialogInterface dialog ) {

                    if (mImageCaptureUri != null ) {
                        getContentResolver().delete(mImageCaptureUri, null, null );
                        mImageCaptureUri = null;
                    }
                }
            } );

            AlertDialog alert = builder.create();

            alert.show();
        }
    }
}

Activtiy result:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != RESULT_OK) return;

    switch (requestCode) {
        case PICK_IMAGE:
            mImageCaptureUri = data.getData();
            doCrop();
            break;
        case CROP_FROM_CAMERA:
            Bundle extras = data.getExtras();
            if (extras != null) {
                Bitmap photo = extras.getParcelable("data");
                imageView.setImageBitmap(photo);
                String root = Environment.getExternalStorageDirectory().toString();
                File myDir = new File(root + "/saved_images");
                myDir.mkdirs();
                Random generator = new Random();
                int n = 100000;
                n = generator.nextInt(n);
                String fname = "Image-"+ n +".jpg";
                File file = new File (myDir, fname);
                if (file.exists ()) file.delete ();
                try {
                    FileOutputStream out = new FileOutputStream(file);
                    photo.compress(Bitmap.CompressFormat.JPEG, 90, out);
                    out.flush();
                    out.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
                SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
                SharedPreferences.Editor editor = preferences.edit();
                editor.putString("image", String.valueOf(mImageCaptureUri));
                editor.commit();

                imageView.setImageURI(mImageCaptureUri);
                imageView.invalidate();
            }
            File f = new File(mImageCaptureUri.getPath());
            if (f.exists()) f.delete();
            break;

    }

Please, don't save image into the Preferences, it's not the storage for large blobs of data, save the cropped image to your data folder as an .jpg or .png image instead and store the URI or path to that cropped image file in your preferences.

Then you'll be able to check if the path is stored in the preferences and load up the cropped image when the application starts.

ok, I've checked your source code once again. In onActivityResult() you have a variable mImageCaptureUri -- save this variable into the Preferences. When you restart your app, use that variable to access the image and crop it again the same way you have cropped the original image.
