Android - Camera intent low bitmap quality
Solution 1
Don't use bitmap
, use uri
instead.
ImageView imageView;
Uri image;
String mCameraFileName;
private void cameraIntent() {
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
Intent intent = new Intent();
intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
Date date = new Date();
DateFormat df = new SimpleDateFormat("-mm-ss");
String newPicFile = df.format(date) + ".jpg";
String outPath = "/sdcard/" + newPicFile;
File outFile = new File(outPath);
mCameraFileName = outFile.toString();
Uri outuri = Uri.fromFile(outFile);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outuri);
startActivityForResult(intent, 2);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == 2) {
if (data != null) {
image = data.getData();
imageView.setImageURI(image);
imageView.setVisibility(View.VISIBLE);
}
if (image == null && mCameraFileName != null) {
image = Uri.fromFile(new File(mCameraFileName));
imageView.setImageURI(image);
imageView.setVisibility(View.VISIBLE);
}
File file = new File(mCameraFileName);
if (!file.exists()) {
file.mkdir();
}
}
}
}

in your cameraIntent you need to specify the uri when the camera activity will save the picture with the full resolution:
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, capturedImageUri);
if you don't specify that you just receive a thumbnail in the onActivityResult. So you specify that and you read the image from the uri.
So in your onActivityResult you should do:
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(capturedImageUri, options);
that's it.

When taking a picture using the android camera Intent, I get a low-quality bitmap image. I was wondering if it is possible to make this image decent quality.
I googled some information about it and I think that I have to use 'EXTRA_OUTPUT' (http://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE)
I am struggling because I don't know where to place it and I don't know if it will solve my problem.
After pressing btnTakePhoto, I change layout and open the android camera. The bitmap shows up in a second layout (low quality). Here is my code:
import android.content.Intent; import android.graphics.Bitmap; import android.provider.MediaStore; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.ImageButton; import android.widget.ImageView; public class Camera extends AppCompatActivity { ImageButton btnTakePhoto; ImageView imgTakenPhoto; private static final int CAM_REQUEST = 1313; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.camera); btnTakePhoto = (ImageButton) findViewById(R.id.buttonFoto); imgTakenPhoto = (ImageView) findViewById(R.id.genomenFoto); btnTakePhoto.setOnClickListener(new btnTakePhotoClicker()); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(requestCode == CAM_REQUEST){ setContentView(R.layout.share); Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); imgTakenPhoto = (ImageView) findViewById(R.id.genomenFoto); imgTakenPhoto.setImageBitmap(thumbnail); } } class btnTakePhotoClicker implements Button.OnClickListener { @Override public void onClick(View v) { Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(cameraIntent, CAM_REQUEST); } } //CameraShare layout -- back button - Go back to first layout public void ibBackToPhotograph(View v) { setContentView(R.layout.camera); btnTakePhoto = (ImageButton) findViewById(R.id.buttonFoto); btnTakePhoto.setOnClickListener(new btnTakePhotoClicker()); } }
EDIT: The image isn't saved anywhere. It's ment to be posted on facebook after you accept it (snapchat)
