I'm working on an Android app, that connects to a .crl file on the Internet and gets some data from it. I need to be able to decode this file (like the ASN.1 JavaScript decoder) and then use the decoded data.
how can I access the decoded data from my Android app? Is there some way to reference the decoded text online?

View 3 Replies View RelatedI know the absolute path of an image (say for eg, /sdcard/cats.jpg). Is there any way to the content uri for this file? Actually in my code I download an image and save it at a particular location. In order to set the image in an ImageView currently I open the file using the path, get the bytes and create a bitmap and then set the bitmap in the ImageView. This is a very slow process, instead if I could get the content uri then I could very easily use the method ImageView.setImageUri(uri)

In android it is not directly possible to share files and folders across different application. The only way is Content Providers.
1. Is there any general (any file type) content store? Today there is Audio, Video and Image Store.
2. Wanted to write new Content Provider to store Big files, like Video and Audio. Saw some examples, like

I want to know how to return an input stream to my client.

I am tring to get a image from the images stored on the sdcard of my Android but i am getting a skia error using BitmapFactory When I just take the image directly without using BitmapFactory class I get the image. But the purpose of using BitmapFactory is scaling down the image size by using inSample =4;
but I get skia as the error..................
I'm downsampling an image via BitmapFactory.decode then base64 encoding the bytes to ship to the server. (long story on the latter part of that formula) It seems this process nukes all Exif data in the image data. Am I approaching this the wrong way or is this a fact of life?

This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?
View 2 Replies View RelatedI have a couple of videos, that I would like to strip the audio from, and was planning to use FLAC, and/or similar lossless codec; but before I do this, what codecs can Andriod decrypt? According to Android Central, it can decode FLAC, but only in Android 4.0 and higher, and I'm currently on Android 2.3.4 on a HTC Amaze 4G...
Is there any software I could get, in order for it to decode/decrypt FLAC correctly?
I don't mind using any other lossless audio codec, as long as Android 2.3.4 supports it...
