android-gallery

问题 I am creating an app which uploads a selected image from the gallery and uploads it to a web service. The webservice requires the filename of selected image plus a base64 encoding of the file contents. I have managed to achieve this with a hardcoded file path. However, I am struggling to get the real filepath of the image. I have read around the web and have this code, but it does not work for me: public void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode ==

问题 This question was originally asked for Android 1.6. I am working on photos options in my app. I have a button and an ImageView in my Activity. When I click the button it would redirect to the gallery and I would be able to select an image. The selected image would appear in my ImageView. 回答1: Updated answer, nearly 5 years later: The code in the original answer no longer works reliably, as images from various sources sometimes return with a different content URI, i.e. content:// rather than
