Save clicked images into custom folder(Preferably internal to the app ) instead of gallery

Question

I am trying to incorporate the camera functionality into the application. I am able to save pictures into the custom folder, but the problem is that the images are getting saved into camera folder(where the camera pics get saved) also. So there is a duplicate images for every image that I take. I don't want that. Following is the code:

public class PhotoIntentActivity extends Activity {

    private static final int ACTION_TAKE_PHOTO_B = 1;

    private static final String BITMAP_STORAGE_KEY = "viewbitmap";
    private static final String IMAGEVIEW_VISIBILITY_STORAGE_KEY = "imageviewvisibility";
    private ImageView mImageView;
    private Bitmap mImageBitmap;

    private String mCurrentPhotoPath;

    private static final String JPEG_FILE_PREFIX = "IMG_";
    private static final String JPEG_FILE_SUFFIX = ".jpg";

    private AlbumStorageDirFactory mAlbumStorageDirFactory = null;

    /* Photo album for this application */
    private String getAlbumName() {
        return getString(R.string.album_name);
    }

    private File getAlbumDir() {
        File storageDir = null;

        if (Environment.MEDIA_MOUNTED.equals(Environment
                .getExternalStorageState())) {

            storageDir = mAlbumStorageDirFactory
                    .getAlbumStorageDir(getAlbumName(), getApplicationContext());

            if (storageDir != null) {
                if (!storageDir.mkdirs()) {
                    if (!storageDir.exists()) {
                        Log.d("CameraSample", "failed to create directory");
                        return null;
                    }
                }
            }

        } else {
            Log.v(getString(R.string.app_name),
                    "External storage is not mounted READ/WRITE.");
        }

        return storageDir;
    }

    private File createImageFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
                .format(new Date());

        File albumF = getAlbumDir();
        File imageF = File.createTempFile(imageFileName, JPEG_FILE_SUFFIX,
                albumF);
        return imageF;
    }

    private File setUpPhotoFile() throws IOException {

        File f = createImageFile();
        mCurrentPhotoPath = f.getAbsolutePath();

        return f;
    }

    private void setPic() {

        /* There isn't enough memory to open up more than a couple camera photos */
        /* So pre-scale the target bitmap into which the file is decoded */

        /* Get the size of the ImageView */
        int targetW = mImageView.getWidth();
        int targetH = mImageView.getHeight();

Thanks in advance.

Answer 1

You can delete the file once it's saved in your custom file. If you're not sure of the name of the file the camera took, you can look at the time stamp or, if you're willing to go crazy, you can use FileObserver to wait for the file to be finished writing before deleting it (if concurrency is an issue and something bad happens.)

After doing some research, I found that that answer is posted here: Double save image

Answer 2

The best solution is saved under application cache directory which only accessible from you re application context context.getCacheDir()

Or use this class and call ExternalStorage.getSDCacheDir(context,"dirname");

import java.io.File;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

import android.content.Context;


public class ExternalStorage {
// Convention for external storage path used by Android 2.2.
private static final String EXT_STORAGE_ROOT_PREFIX = "/Android/data/";
private static final String EXT_STORAGE_ROOT_SUFFIX = "/files/";

private static StringBuilder sStoragePath = new StringBuilder();

private static final String ALTERNATE_SDCARD_MOUNTS[] = { "/emmc", 
        "/sdcard/ext_sd", // Newer (2011) HTC devices (Flyer, Rezound)
        "/sdcard-ext", // Some Motorola devices (RAZR)
        "/sdcard/sd", // Older Samsung Galaxy S (Captivate)
        "/sdcard/sdcard" // Archos tablets
};

/**
 * Create given directory on sd card application cache Directory.

        // Get the directory on the SD card to store content
        // Attempt to use getExternalFilesDir() if we are on Android 2.2 or newer

                break;

            cacheDir = null; // Failed to create folder

    }

    // Fall back on internal cache as a last resort
