    <p>Im working on this game for android. </p> <p>And wanted to know if my thread architecture was right or wrong. </p> <p>Basically, what is happening is, i am loading All the bitmaps,sounds etc in the initializevariables() method. </p> <p>But sometimes the game crashes and sometimes it doesnt. So i decided to use async task. But that doesnt seem to work either (i too loads at times and crashes at times)</p> <pre><code> @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setFullScreen(); initializeVariables(); new initVariables().execute(); // setContentView(ourV); } private void setFullScreen() { requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON ); } private void initializeVariables() { ourV=new OurView(this); stats = getSharedPreferences(filename, 0); ballPic = BitmapFactory.decodeResource(getResources(), R.drawable.ball5); platform = BitmapFactory.decodeResource(getResources(), R.drawable.platform3); gameB = BitmapFactory.decodeResource(getResources(), R.drawable.game_back2); waves = BitmapFactory.decodeResource(getResources(), R.drawable.waves); play = BitmapFactory.decodeResource(getResources(), R.drawable.play_icon); pause = BitmapFactory.decodeResource(getResources(), R.drawable.pause_icon); platform2 = BitmapFactory.decodeResource(getResources(), R.drawable.platform4); countdown = BitmapFactory.decodeResource(getResources(), R.drawable.countdown); bubbles = BitmapFactory.decodeResource(getResources(), R.drawable.waves_bubbles); backgroundMusic = MediaPlayer.create(this, R.raw.music); jump = MediaPlayer.create(this, R.raw.jump); click = MediaPlayer.create(this, R.raw.jump_crack); sm = (SensorManager) getSystemService(SENSOR_SERVICE); acc = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); sm.registerListener(this, acc, SensorManager.SENSOR_DELAY_GAME); ourV.setOnTouchListener(this); dialog = new Dialog(this,android.R.style.Theme_Translucent_NoTitleBar_Fullscreen); dialog.setContentView(R.layout.pausescreen); dialog.hide(); dialog.setOnDismissListener(this); resume = (Button) dialog.findViewById(R.id.bContinue); menu = (Button) dialog.findViewById(R.id.bMainMenu); newTry = (Button) dialog.findViewById(R.id.bNewTry); tv_time = (TextView) dialog.findViewById(R.id.tv_time); tv_day = (TextView) dialog.findViewById(R.id.tv_day); tv_date = (TextView) dialog.findViewById(R.id.tv_date); resume.setOnClickListener(this); menu.setOnClickListener(this); newTry.setOnClickListener(this); } @Override protected void onResume() { //if its running the first time it goes in the brackets if(firstStart) { ourV.onResume(); firstStart=false; } } </code></pre> <p>Now what onResume in ourV does is , its responsible for starting the thread </p> <pre><code> //this is ourV.onResume public void onResume() { t=new Thread(this); isRunning=true; t.start(); } </code></pre> <p>Now what I want is to initialise all bitmaps sounds etc in the async background method </p> <pre><code> public class initVariables extends AsyncTask&lt;Void, Integer, Void&gt; { ProgressDialog pd; @Override protected void onPreExecute() { pd = new ProgressDialog(GameActivity.this); pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); pd.setMax(100); pd.show(); } @Override protected Void doInBackground(Void... arg0) { synchronized (this) { for(int i=0;i&lt;20;i++) { publishProgress(5); try { Thread.sleep(89); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } return null; } @Override protected void onProgressUpdate(Integer... values) { pd.incrementProgressBy(values[0]); } @Override protected void onPostExecute(Void result) { pd.dismiss(); setContentView(ourV); } } </code></pre> <p>Now since I am new to this. You could tellme maybe if async is not required for such stuff and there is another way of doing it normally.</p>
