I'm using this function for saving images to SD card, but I keep getting this error
Here is my saveImage function:
private void saveImage() {
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... arg0) {
@SuppressWarnings("deprecation")
String FILENAME = getString(R.string.app_name)
+ new Date().getDate();
try {
@SuppressWarnings("unused")
FileOutputStream fos = null;
fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
parent.setDrawingCacheEnabled(true);
Bitmap bitmap = parent.getDrawingCache();
Canvas canvas = new Canvas(bitmap);
parent.draw(canvas);
// bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
File dir = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/" + getString(R.string.app_name));
dir.mkdirs();
String path = Environment.getExternalStorageDirectory()
.toString();
OutputStream fOut = null;
String ime = getIntent().getStringExtra("ime");
File file = new File(dir.getAbsolutePath(), ime + ".jpg");
try {
fOut = new FileOutputStream(file);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
try {
fOut.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
fOut.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
MediaStore.Images.Media.insertImage(getContentResolver(),
file.getAbsolutePath(), file.getName(),
file.getName());
} catch (FileNotFoundException e) {
Toast.makeText(Draw.this, getString(R.string.error),
Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void result) {
Toast.makeText(getApplicationContext(), R.string.imageSaved_mk,
Toast.LENGTH_SHORT).show();
super.onPostExecute(result);
}
}.execute();
}
And output from logCat:
