Question

I have a custom camera app and I want to pass the captured photo into another activity where I can add other icons (emoticons) over it.

How can i pass the captured photo to another activity?

Answer 1

You could pass the photo's URI via an intent. Assuming you call your camera with startActivityForResult(). In your camera activity:

Intent data = new Intent();
data.putExtra(MediaStore.EXTRA_OUTPUT, imageFilename);
setResult(Activity.RESULT_OK, data);
finish();

Then in your emoticon activity:

@Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (data != null && data.hasExtra(MediaStore.EXTRA_OUTPUT)) {
        File imageFile = new File(data.getStringExtra(MediaStore.EXTRA_OUTPUT));

        // Bitmap here, do whatever you need
        Bitmap bitmap = readBitmapFromFile(imageFile.getName());
    }
}

public static Bitmap readBitmapFromFile(@NotNull String filename) {
    File file = new File(filename);

    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inPreferredConfig = Bitmap.Config.RGB_565;
    bmOptions.inSampleSize = 1;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath(), bmOptions);

    return bitmap;
}
