I successfully have used this code snippet before, but with the file pointing to somewhere on the SD card.
final File temp = new File(getCacheDir(), "temp.jpg");
temp.delete();
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(temp));
startActivityForResult(intent, CONFIG.Intents.Actions.SELECT_CAMERA_PHOTO);
However when I use getCacheDir instead of a loc on the SD card it seems the photo is never saved. Is this a limitation of cache dir and image capture?
Technically, this is because writing to internal storage is not supported when using the Camera application to capture an image. In fact, you may notice an exception printed in logcat stating
Writing to internal storage is not supported
. However, the real reason this doesn't work is because by default you are creating a file that is private to your application package and another application (i.e. the Camera app) can't access that file location because it doesn't have permission to do so. External storage is the only globally accessibly portion of the filesystem.The workaround is for you to create the file with global (WORLD_WRITEABLE) permissions. Typically, this allows the Camera app to access the file via the passed Uri. There aren't really methods to do this directly on
File
, so you have to create the file using the methods available inContext
and then grab a handle to it afterward:This also sort of limits where you can place the file since the
Context
methods inherently create files in the root "files" directory, and you can't redirect that to the cache directory.HTH
Best solution I found is: FileProvider (needs support-library-v4)
It uses the internal storage! https://developer.android.com/reference/android/support/v4/content/FileProvider.html
Define your FileProvider in Manifest in Application element:
Add camera feature to AndroidManifest.xml's root element if mandatory:
Define your image paths in for example res/xml/image_path.xml:
Java:
4.1 capture intent:
4.2 onActivityResult():
