How can I save an image from a url?
android, android-imageview
Solution
You have to save it in SD card or in your package data, because on runtime you only have access to these. To do that this is a good example
URL url = new URL ("file://some/path/anImage.png");
InputStream input = url.openStream();
try {
//The sdcard directory e.g. '/sdcard' can be used directly, or
//more safely abstracted with getExternalStorageDirectory()
File storagePath = Environment.getExternalStorageDirectory();
OutputStream output = new FileOutputStream (storagePath + "/myImage.png");
try {
byte[] buffer = new byte[aReasonableSize];
int bytesRead = 0;
while ((bytesRead = input.read(buffer, 0, buffer.length)) >= 0) {
output.write(buffer, 0, bytesRead);
}
} finally {
output.close();
}
} finally {
input.close();
}

Problem
I'm setting an ImageView using `setImageBitmap` with an external image url. I would like to save the image so it can be used later on even if there is no internet connection. Where and how can I save it?
