Android Camera Intent: how to get full sized photo?

Solution 1:

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

Solution 2:

Open Camera and save image into some specific directory

private String pictureImagePath = "";
private void openBackCamera() {
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = timeStamp + ".jpg";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    pictureImagePath = storageDir.getAbsolutePath() + "/" + imageFileName;
    File file = new File(pictureImagePath);
    Uri outputFileUri = Uri.fromFile(file);
    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);               
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
    startActivityForResult(cameraIntent, 1);
}

Handle Image

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1) {
    File imgFile = new  File(pictureImagePath);
        if(imgFile.exists()){        
       Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
       ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
       myImage.setImageBitmap(myBitmap);

        }
    }

}
