Hi,
I had the same problem and it seems that you have to compress the
image before saving it t the disk.
And I think you also have to flush the OutputStream.
This is how I'm doing it. Hope it helps you:
public boolean storeImage(Bitmap bitmap, int picId) {
try {
File baseDir = Environment.getExternalStorageDirectory();
File tmpDir = new File(baseDir, APP_BASE_DIR + APP_CACHE_DIR);
if (!tmpDir.exists())
tmpDir.mkdirs();
File file = new File(tmpDir,String.valueOf(picId));
BufferedOutputStream out = new BufferedOutputStream(new
FileOutputStream(file));
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
//bitmap.recycle();
return true;
} catch (IOException e) {
e.printStackTrace(); // TODO: Customize this generated block
return false;
}
}
