Getting an image from Gallery on from the Picasa//

Question

I am trying to get an image from the gallery app from one of the folders from the Google+ synced photos. After selecting the image, the Uri is being passed back correctly. But when I try to get the actual path of that image on the storage device, so that I can use it, it crashes. The problem seems to be specifically with the picasa content provider.

Tested on Nexus S and Nexus 7, and other devices as well.

E/AndroidRuntime(14572): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { dat=content://com.google.android.gallery3d.provider/picasa/item/5427003652908228690 }}

Here, the dat field seems to be correctly passing the Uri, but when I try to fetch the image's location, it crashes with the following error.

W/GalleryProvider(14381): unsupported column: _data

Seems that the content provider for Picasa albums doesn't have a _data field.

The code for getting the location is:

// imageUri is the Uri from above.
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = context.getContentResolver().query(imageUri, proj,null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();

String filePath = cursor.getString(column_index);
cursor.close();

The only columns that seem to be supported for this image are: [user_account, picasa_id, _display_name, _size, mime_type, datetaken, latitude, longitude, orientation]

How do we get the actual location of this image. And if we are not supposed to work with this image, these images shouldn't be shown to the user in the first place.

The Intent to launch the gallery app is:

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

Answer 1

I wasted now lots of hours and now i found a solution which works in all cases without any magic downloading in special threads or something. The following method returns a stream from the content which the user selected and this works with everything in the wild.

FileInputStream getSourceStream(Uri u) throws FileNotFoundException {
    FileInputStream out = null;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        ParcelFileDescriptor parcelFileDescriptor =
                mContext.getContentResolver().openFileDescriptor(u, "r");
        FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
        out = new FileInputStream(fileDescriptor);
    } else {
        out = (FileInputStream) mContext.getContentResolver().openInputStream(u);
    }
    return out;
}

Answer 2

I faced the same problem about year ago.. I show you my solution (code is quite messy, please refactor it). So, you have the image URI which was returned from gallery:

    ImageInfo getImage(URI imageUri) {

        ImageInfo result = null;

        final String[] cursorColumns = {MediaStore.Images.Media.DATA, MediaStore.Images.Media.ORIENTATION};

        // some devices (OS versions return an URI of com.android instead of com.google.android
        if (imageUri.toString().startsWith("content://com.android.gallery3d.provider"))  {
            // use the com.google provider, not the com.android provider.
            imageUri = Uri.parse(imageUri.toString().replace("com.android.gallery3d","com.google.android.gallery3d"));
        }

        Cursor cursor = App.getContext().getContentResolver().query(imageUri, cursorColumns, null, null, null);
        if (cursor != null) {

            int dataColumnIndex = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
            int orientationColumnIndex = cursor.getColumnIndex(MediaStore.Images.ImageColumns.ORIENTATION);

            cursor.moveToFirst();

            // if it is a picasa image on newer devices with OS 3.0 and up
            if (imageUri.toString().startsWith("content://com.google.android.gallery3d")) {

                result = new ImageInfo(downloadImage(imageUri), "0");                       

            } else { // it is a regular local image file

                result = new ImageInfo(cursor.getString(dataColumnIndex), cursor.getString(orientationColumnIndex));

            }

            cursor.close();

        } else {
            result = new ImageInfo(downloadImage(imageUri), "0");
        }

        return result;                      
}

And now we need function to download image:

private String downloadImage(URI imageUri) {

    File cacheDir;
    // if the device has an SD card
    if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)) {
        cacheDir = new File(android.os.Environment.getExternalStorageDirectory(),".OCFL311");
    } else {
        // it does not have an SD card
        cacheDir = App.getContext().getCacheDir();
    }

    if(!cacheDir.exists()) cacheDir.mkdirs();
    File f = new File(cacheDir, PUT_HERE_FILE_NAME_TO_STORE_IMAGE);

    try {

        InputStream is = null;
        if (imageUri.toString().startsWith("content://com.google.android.gallery3d")) {
            is = App.getContext().getContentResolver().openInputStream(imageUri);
        } else {
            is = new URL(imageUri.toString()).openStream();
        }

        OutputStream os = new FileOutputStream(f);
        Utils.InputToOutputStream(is, os);

        return f.getAbsolutePath();
    } catch (Exception ex) {
        Log.d(this.getClass().getName(), "Exception: " + ex.getMessage());
        // something went wrong
        ex.printStackTrace();
        return null;
    }
}

ImageInfo is my class to store path to image and its orientation.

public static class ImageInfo {
    public final String filePath;
    public final String imageOrientation;

    public ImageInfo(String filePath, String imageOrientation) {
        this.filePath = filePath;

        if (imageOrientation == null) imageOrientation = "0";
        this.imageOrientation = imageOrientation;           
    }
}

Answer 3

Below trick worked for me, what i am doing here is if there is any authority url in URI, then i am creating a temporary image using below code & returning the Content URI of the same.

I have answered similar question here as well..

public static String getImageUrlWithAuthority(Context context, Uri uri) {
    InputStream is = null;
    if (uri.getAuthority() != null) {
        try {
            is = context.getContentResolver().openInputStream(uri);
            Bitmap bmp = BitmapFactory.decodeStream(is);
            return writeToTempImageAndGetPathUri(context, bmp).toString();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }finally {
            try {
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
    return null;
}

public static Uri writeToTempImageAndGetPathUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

Based on @drindt answer, below codes give downloaded temporary File path from Google Photo cloud-synced-but-not-in-device file.

    if ("content".equalsIgnoreCase(uri.getScheme())) {
        String result = getDataColumn(context, uri, null, null); // 
        if (TextUtils.isEmpty(result))
            if (uri.getAuthority().contains("com.google.android")) {

Answer 5

I used this approach, works fine for me, hope this will helps you ....

ACTIVITYRESULT_CHOOSEPICTURE is the int you use when calling startActivity(intent, requestCode);

public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if(requestCode == ACTIVITYRESULT_CHOOSEPICTURE) {
    BitmapFactory.Options options = new BitmapFactory.Options();
    final InputStream ist = ontext.getContentResolver().openInputStream(intent.getData());
    final Bitmap bitmap = BitmapFactory.decodeStream(ist, null, options);
    ist.close();
  }
}

if above code doesn't work than just refer this link... it will surly shows the way

Answer 6

Finally ended with a classic solution...By using Document.util, which covers all authority :-1-Inside your onActivityResult():-

case GALLERY_CAPTURE_IMAGE_REQUEST_CODE:
                    String filePath = DocumentUtils.getPath(MainContainerActivity.this,data.getData();

                    break;

2- Create class DocumentUtils:-

public class DocumentUtils {

@TargetApi(Build.VERSION_CODES.KITKAT)
public static String getPath(final Context context, final Uri uri) {

    final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;

    // DocumentProvider
    if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
        // ExternalStorageProvider
        if (isExternalStorageDocument(uri)) {
            final String docId = DocumentsContract.getDocumentId(uri);
            final String[] split = docId.split(":");
            final String type = split[0];

            if ("primary".equalsIgnoreCase(type)) {
                return Environment.getExternalStorageDirectory() + "/" + split[1];
            }

            // TODO handle non-primary volumes
        }
        // DownloadsProvider
        else if (isDownloadsDocument(uri)) {

            final String id = DocumentsContract.getDocumentId(uri);
            final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));

            return getDataColumn(context, contentUri, null, null);
        }
        // MediaProvider
        else if (isMediaDocument(uri)) {
            final String docId = DocumentsContract.getDocumentId(uri);
            final String[] split = docId.split(":");
            final String type = split[0];

            Uri contentUri = null;
            if ("image".equals(type)) {
                contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
            } else if ("video".equals(type)) {
                contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
            } else if ("audio".equals(type)) {
                contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
            }

            final String selection = "_id=?";
            final String[] selectionArgs = new String[]{split[1]};

            return getDataColumn(context, contentUri, selection, selectionArgs);
        }
    }
    // MediaStore (and general)
    else if ("content".equalsIgnoreCase(uri.getScheme())) {
        // Return the remote address
        String url;
        if (isGooglePhotosUri(uri)) {
            url = getDataColumnWithAuthority(context, uri, null, null);
            return getDataColumn(context, Uri.parse(url), null, null);
        }

        return getDataColumn(context, uri, null, null);

    }
    // File
    else if ("file".equalsIgnoreCase(uri.getScheme())) {
        return uri.getPath();
    }

    return null;
}

3- Also you will need following function in ImageLoader.java:-

public static Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}
