Android Camera Intent: how to get full sized photo

androidbitmapcamera

I am using intent to launch camera:

Intent cameraIntent = new Intent(
    android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
getParent().startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

and using:

Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
photoImage.setImageBitmap(thumbnail);
photoImage.setVisibility(View.VISIBLE);

But it is only a thumbnail, how do I get the full bitmap? I know I can use my own Activity and use:

Camera.PictureCallback()

But is there anyway to do it using Intent?

Thanks!

edit:

I also tried:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Uri uri = data.getData();
    imageView.setImageURI(uri);
}

It works for photo selected from gallery, but for camera intent, data.getData() returns null.

To get full sized camera image you should point camera to save picture in temporary file, like:

    private URI mImageUri;

    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    File photo;
    try
    {
        // place where to store camera taken picture
        photo = this.createTemporaryFile("picture", ".jpg");
        photo.delete();
    }
    catch(Exception e)
    {
        Log.v(TAG, "Can't create file to take picture!");
        Toast.makeText(activity, "Please check SD card! Image shot is impossible!", 10000);
        return false;
    }
    mImageUri = Uri.fromFile(photo);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
    //start camera intent
    activity.startActivityForResult(this, intent, MenuShootImage);

private File createTemporaryFile(String part, String ext) throws Exception
{
    File tempDir= Environment.getExternalStorageDirectory();
    tempDir=new File(tempDir.getAbsolutePath()+"/.temp/");
    if(!tempDir.exists())
    {
        tempDir.mkdirs();
    }
    return File.createTempFile(part, ext, tempDir);
}

Then after image capture intent finished to work - just grab your picture from imageUri using following code:

public void grabImage(ImageView imageView)
{
    this.getContentResolver().notifyChange(mImageUri, null);
    ContentResolver cr = this.getContentResolver();
    Bitmap bitmap;
    try
    {
        bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, mImageUri);
        imageView.setImageBitmap(bitmap);
    }
    catch (Exception e)
    {
        Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
        Log.d(TAG, "Failed to load", e);
    }
}


//called after camera intent finished
@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    //MenuShootImage is user defined menu option to shoot image
    if(requestCode==MenuShootImage && resultCode==RESULT_OK) 
    {
       ImageView imageView;
       //... some code to inflate/create/find appropriate ImageView to place grabbed image
       this.grabImage(imageView);
    }
    super.onActivityResult(requestCode, resultCode, intent);
}

P.S. Code need to be revised with respect to new security restriction applied in Android M - FileProvider: mImageUri has to be packed with FileProvider

Java – Intent problem, return value (Android)

I think you got the directions mixed up.

In the Repository class you have to setResult() before calling finish. For additional Data you can putExtra() data.

For example, set your result in the onCreate() function.

In your calling class (the one that starts Repository) you overwrite onActivityResult(int requestCode, int resultCode, Intent data) and get data with data.getBundleExtra().

Androids reference for Intent and Activity has good descriptions and the samples also contain a ReceiveResult and SendResult sample.
