This is my code line 1925 and 1852 is point out in a code below
FileInputStream tempStream = null;
try {
**LINE 1925** tempStream = new FileInputStream(newFile);
bytesAvailable = tempStream.available();
if (bytesAvailable > 1024000 && bitmapImage != null) {
AppnameApplication.getResizedBitmap(bitmapImage, 1024);
if (newFile.exists()) newFile.delete();
FileOutputStream out = new FileOutputStream(newFile);
bitmapImage.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
}
tempStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Can you show me how to do it and it seem error coming from FileInputStream tempStream = null; can anyone help me please am still learning Android Studio.
More information how the code works
