Android Camera Intent: how to get full sized photo?

hzxu picture hzxu · Jun 23, 2011 · Viewed 90.3k times · Source

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
