public class MainActivity extends AppCompatActivity {
Button save;
Bitmap bitmap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Drawable drawable = getResources().getDrawable(R.drawable.mario);
bitmap = ((BitmapDrawable) drawable).getBitmap();
save = findViewById(R.id.save);
save.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ContextWrapper cw = new ContextWrapper(getApplicationContext());
File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
File file = new File(directory, "UniqueFileName" + ".jpg");
if (!file.exists()) {
Log.d("path", file.toString());
FileOutputStream fos = null;
try {
fos = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
} catch (java.io.IOException e) {
e.printStackTrace();
}
}
