FATAL EXCEPTION: ThumbnailManager-1 while sharing images to Intent

Question

I got following Exception while sharing images using FileProvider. Following is the code I used to.

{

  ArrayList<Uri> files = new ArrayList<Uri>();
  files.add(getImageUriFromCache(context,bitmap,fileName));

}


private void startSharingIntent(ArrayList<Uri> files,String caption){
Intent i=new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
            i.setType("image/png");
            i.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            i.putExtra(Intent.EXTRA_SUBJECT, "my app share");
            i.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files);
            i.putExtra(Intent.EXTRA_TEXT,caption);
            i.putExtra(Intent.EXTRA_TITLE,caption);
            context.startActivity(Intent.createChooser(i, "Tital"));
        }

public Uri getImageUriFromCache(Context inContext, Bitmap inImage , String fileId) throws IOException{

                File cachePath = new File(inContext.getFilesDir() , "images/");
                cachePath.mkdirs(); // don't forget to make the directory
                File newFile = new File(cachePath, "im"+fileId+"_post.png");
                newFile.setReadable(true, false);
                FileOutputStream stream = new FileOutputStream(newFile); // overwrites this image every time
                inImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
                stream.close();
                Uri contentUri = FileProvider.getUriForFile(inContext, "com.xx.xx.fileprovider", newFile);
                return contentUri;
}

Detail stack trace of exception is as follows.

Images are shared correctly when I choose email to share, but failed when I select messaging. Please assist.

Any update on this, AMY? Seeing a very similar issue on samsung devices when sharing to their Messaging app (which is a fork of Android's com.android.mms app, I think). – Gio

Answer 1

According to the sources, the Android UriImage class (of the Mms app) tries to read the orientation of the image you provide. It does that by running a query on the Uri you provided asking for the MediaStore.Images.ImageColumns.ORIENTATION column.

I didn't find recent sources of the FileProvider class, but this older FileProvider.java version only supports two column names:

• OpenableColumns.DISPLAY_NAME
• OpenableColumns.SIZE

If none of these two columns are requested it will just return an empty row (with no columns at all).

In your case the empty row causes the MMS app to crash when it requests a column with the index 0.

So what can you do?

I see at least three possible options. All of them involve creating your own Subclass of FileProvider which overrides the query method.

It depends on your goal and skill levels which one is best for you. I try to list them from "simple" to "quite a bit of work".

• check the projection array and throw an IllegalArgumentException if any column other than DISPLAY_NAME or SIZE appears in it. This should work because the MMS app seems to ignore this exception. This might break other apps though.

• check the projection and append the requested ORIENTATION column with a value of 0 (indicating the image doesn't need any rotating).

  Here is some (untested) code to implement this:

    @Override
    public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder)
    {
        Cursor cursor = super.query(uri, projection, selection, selectionArgs, sortOrder);
        if (    cursor == null &&
                projection != null
                && projection.length == 1
                && MediaStore.Images.ImageColumns.ORIENTATION.equals(projection[0])) {
            // query from MMS app, return a single row with a 0 value
            final MatrixCursor matrixCursor = new MatrixCursor(projection, 1);
            matrixCursor.addRow(new Integer[]{0});
            cursor = matrixCursor;
        }
        return cursor;
    }
  

• check the projection and append the requested ORIENTATION column with the actual value from the EXIF tag, if present in the image.

I tried finding a way to add the orientation tag (with ContentValues) to the Uri to set the orientation parameter, but was unsuccessful (default FileProvider doesn't implement the insert method). How would you implement the second bullet point (override query in a custom FileProvider)? – Pidgin

I tested it out and it worked (with minor changes). Thanks! – Pidgin
