Quiero guardar la imagen en la carpeta de mi unidad local o en la carpeta res/drawable
en mi aplicación. Ahora estoy guardando img en una tarjeta SD, pero tengo que guardarlo en la carpeta res/drawable. Mi código es:guardar la imagen de android en la carpeta res/drawable
String image_URL = "http://chart.apis.google.com/chart?chs=200x200&cht=qr&chl=http%3A%2F%2Fandroid-er.blogspot.com%2F";
String extStorageDirectory;
Bitmap bm;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button buttonSave = (Button) findViewById(R.id.save);
ImageView bmImage = (ImageView) findViewById(R.id.image);
BitmapFactory.Options bmOptions;
bmOptions = new BitmapFactory.Options();
bmOptions.inSampleSize = 1;
bm = LoadImage(image_URL, bmOptions);
bmImage.setImageBitmap(bm);
extStorageDirectory = Environment.getExternalStorageState().toString();
extStorageDirectory = Environment.getExternalStorageDirectory()
.toString();
buttonSave.setText("Save to " + extStorageDirectory + "/qr.PNG");
buttonSave.setOnClickListener(buttonSaveOnClickListener);
}
private Bitmap LoadImage(String URL, BitmapFactory.Options options) {
Bitmap bitmap = null;
InputStream in = null;
try {
in = OpenHttpConnection(URL);
bitmap = BitmapFactory.decodeStream(in, null, options);
in.close();
} catch (IOException e1) {
}
return bitmap;
}
private InputStream OpenHttpConnection(String strURL) throws IOException {
InputStream inputStream = null;
URL url = new URL(strURL);
URLConnection conn = url.openConnection();
try {
HttpURLConnection httpConn = (HttpURLConnection) conn;
httpConn.setRequestMethod("GET");
httpConn.connect();
if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
inputStream = httpConn.getInputStream();
}
} catch (Exception ex) {
}
return inputStream;
}
Button.OnClickListener buttonSaveOnClickListener = new Button.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
OutputStream outStream = null;
File file = new File(extStorageDirectory, "er.PNG");
try {
outStream = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
Toast.makeText(LoadSaveImgActivity.this, "Saved",
Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
