I have 3 images taken from camera and I want to set to 3 ImageView. But it throws OutOfMemory because the image has large size. I've read that bitmap factory can compress the size without reducing the quality. The problem is I don't know how to do that.
This is my onClick Button:
openCameraButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(Environment.getExternalStorageDirectory(),
"imagename.jpg");
outPutfileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outPutfileUri);
startActivityForResult(intent,0);
dialog.cancel();
}
});
And this is my onActivityResult:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//result from camera
try{
if (requestCode==0 && resultCode==RESULT_OK){
//bitmap = (Bitmap)data.getExtras().get("data");
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), outPutfileUri);
drawable = new BitmapDrawable(getResources(), bitmap);
imageSelfie.setImageDrawable(drawable);
}
} catch (Exception ignored){}}
Anyone can help me?
Use like this :
File file = new File(Environment.getExternalStorageDirectory(),"imagename.jpg");
fileDeleted = !file.exists() || file.delete();
if (fileDeleted) {
FileOutputStream out = new FileOutputStream(file);
if (imageToSave != null) {
imageToSave.compress(Bitmap.CompressFormat.JPEG, 65, out);
}}
out.flush();
out.close();
Instead of using the media store which tries to give you a full bitmap you better open an inputstream and load a resized bitmap from it.
InputStream is = getContentResolver().openInputStream(outPutfileUri);
Then use BitmapFactory.decodeStream() with an options parameter where you scale down the image several times.
