ONScripter Engine for Android

This project is forked from the original author at Studio O.G.A (http://onscripter.osdn.jp/onscripter.html). This fork is suppose to fix many issues and play almost any ONScripter game of any language.

The original project only supported Japanese text however my project supports Japanese, English, Korean, Chinese, and UTF-8 (like Spanish, Russian, French, German etc) which covers the bulk of Europe and other non-Asian countries.

Changes/Fixes from original ONScripter

Sample integration

This is a very simple example of enabling ONScripter in your app with events.

public class GameActivity extends Activity {
    private ONScripterView mGame;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Defined uri either content:// (external devices like sdcard) or file://
        Uri uri = Uri.fromFile(new File("/path/to/folder/with/game"));

        mGameView = new ONScripterView.Builder(getContext(), uri)
                // If you specify a screenshot folder name, relative to the save folder in game,
                // full sized screenshots are saved after each save
                .setScreenshotPath("")
                // Outline of text
                .useRenderOutline()
                // Plays higher quality audio
                .useHQAudio()
                // Set a default font path
                .setFontPath(defaultFontPath)
                .create();
        setContentView(mGame);

        // [Optional] Receive Events from the game
        mGame.setONScripterEventListener(new ONScripterView.ONScripterEventListener() {
            @Override
            public void autoStateChanged(boolean selected) {
                // User has toggled auto mode
            }

            @Override
            public void skipStateChanged(boolean selected) {
                // User has toggled skip mode
            }

            @Override
            public void singlePageStateChanged(boolean selected) {
                // User has toggled single page mode
            }

            @Override
            public void onUserMessage(UserMessage messageId) {
                if (messageId == ONScripterView.CORRUPT_SAVE_FILE) {
                    Toast.makeText(GameActivity.this, "Cannot open save file, it is corrupted",
                            Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void videoRequested(String filename, boolean clickToSkip, boolean shouldLoop) {
                // Request playing this video in an external video player
                // If you have your own video player built into your app, you can
                // pause this thread and play the video. Unfortunately I was unable
                // to get smpeg library to work within this library
                try {
                    String filename2 = filename.replace('\\', '/');
                    Uri uri = Uri.parse(filename2);
                    Intent i = new Intent(Intent.ACTION_VIEW);
                    i.setDataAndType(uri, "video/*");
                    startActivityForResult(i, -1);
                }
                catch(Exception e){
                    Log.e("ONScripter", "playVideo error:  " + e.getClass().getName());

        FrameLayout.LayoutParams p = (FrameLayout.LayoutParams) mGame.getLayoutParams();
        p.gravity = Gravity.CENTER;
        mGame.setLayoutParams(p);
