    <p>Basically I've got a Menu-class with a start button that starts a new Game Activity within a Thread. </p> <p>In the Game class I've got instantiated a Count-object (which extends CountDownTimer). </p> <p>When starting the Game Activity I get an ANR error and I believe it is caused by the timer, since I've commented it out and it works perfectly fine. Frankly I do not know how to solve this; I've tried different approaches but failed. <strong>Edited code</strong> *<em>Logcat at the end</em>*</p> <pre><code>public class Menu extends Activity { Button start, highscores, exit; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.menu); addListenerOnButton(); } private void addListenerOnButton() { start = (Button) findViewById(R.id.start); start.setOnClickListener(new OnClickListener() { public void onClick(View view) { startActivity(new Intent("net.fb.clauz.GAME")); }; }); highscores = (Button) findViewById(R.id.highscores); highscores.setOnClickListener(new OnClickListener() { public void onClick(View view) { } }); exit = (Button) findViewById(R.id.exit); exit.setOnClickListener(new OnClickListener() { public void onClick(View view) { finish(); System.exit(0); } }); } } public class Game extends Activity { Button button; TextView score; public static TextView timeleft; int x = 0; public Counter count; public static boolean running=true; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.main); count = new Counter(30000, 1000); timeleft = (TextView) findViewById(R.id.timeleftTitle); gameThread = new Thread(new Runnable() { public void run() { while (running) { addListenerOnButton(); count.start(); } } }); gameThread.start(); } private void addListenerOnButton() { button = (Button) findViewById(R.id.button1); button.setOnClickListener(new OnClickListener() { public void onClick(View view) { x++; score = (TextView) findViewById(R.id.score); score.setText(String.valueOf(x)); } }); } } public class Counter extends CountDownTimer{ public Counter(long millisInFuture, long countDownInterval) { super(millisInFuture, countDownInterval); // TODO Auto-generated constructor stub } @Override public void onFinish() { // TODO Auto-generated method stub Game.running = false; // stop the game //need to implement action to return to the buttons menu. } @Override public void onTick(long millisUntilFinished) { // TODO Auto-generated method stub Game.timeleft.setText("Left: " + millisUntilFinished / 1000); System.out.println(millisUntilFinished / 1000); } } </code></pre> <p>Logcat:</p> <pre><code>08-23 11:00:02.963: W/ActivityManager(885): Activity idle timeout for ActivityRecord{b4ca99d0 net.fb.clauz/.Game} 08-23 11:00:18.343: D/dalvikvm(14424): GC_CONCURRENT freed 3397K, 28% free 9419K/12935K, paused 4ms+4ms 08-23 11:00:21.383: I/InputDispatcher(885): Application is not responding: Window{b4cd2aa8 net.fb.clauz/net.fb.clauz.Game paused=false}. 5005.6ms since event, 5004.9ms since wait started 08-23 11:00:21.383: I/WindowManager(885): Input event dispatching timed out sending to net.fb.clauz/net.fb.clauz.Game 08-23 11:00:21.415: I/Process(885): Sending signal.

    1. COyou should add logcat if ANR is showing.

    2. COI think you are just doing too much stuff on the main thread, which causes your app to "ANR". You should use more threading (e.g. your while is way too much work for the mainthread)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
