How to get a Bitmap object from an Uri (if I succeed to store it in
/data/data/MYFOLDER/myimage.png or file///data/data/MYFOLDER/myimage.png) to use it in my application?
Does anyone have an idea on how to accomplish this?
. . IMPORTANT: See answer from @Mark Ingram below and @pjv for at better solution. . .
You could try this:
public Bitmap loadBitmap(String url)
{
Bitmap bm = null;
InputStream is = null;
BufferedInputStream bis = null;
try
{
URLConnection conn = new URL(url).openConnection();
conn.connect();
is = conn.getInputStream();
bis = new BufferedInputStream(is, 8192);
bm = BitmapFactory.decodeStream(bis);
}
catch (Exception e)
{
e.printStackTrace();
}
finally {
if (bis != null)
{
try
{
bis.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
if (is != null)
{
try
{
is.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
return bm;
}
But remember, this method should only be called from within a thread (not GUI -thread). I a AsyncTask.
Here's the correct way of doing it:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK)
{
Uri imageUri = data.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
}
}
If you need to load very large images, the following code will load it in in tiles (avoiding large memory allocations):
BitmapRegionDecoder decoder = BitmapRegionDecoder.newInstance(myStream, false);
Bitmap region = decoder.decodeRegion(new Rect(10, 10, 50, 50), null);
