    <p>Can anyone check my code? Thanks in advance. I have made a story line which is automatically goes to another activity using <code>Intent</code> and <code>Timer</code>. I put a background music and a sound which is the speech of the character in my story line. But when i get to the fifth <code>Activity</code> it Force Close and Gets error in my logcat. </p> <p>Here's my code in my Story line <code>Activity</code>: Page 1 is ok but i paste my code also:</p> <pre><code>public class pgone extends Activity { protected boolean _active = true; protected int _splashTime = 7000; public void onAttachedToWindow() { super.onAttachedToWindow(); Window window = getWindow(); window.setFormat(PixelFormat.RGBA_8888); } MediaPlayer audio; MediaPlayer SLONE; private long splashDelay = 6000; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.pgone); //StartAnimations(); TimerTask task = new TimerTask() { public void run() { Intent mainIntent = new Intent().setClass(pgone.this, pgtwo.class); startActivity(mainIntent); finish(); } }; final Timer timer = new Timer(); timer.schedule(task, splashDelay); audio = MediaPlayer.create(this,R.raw.storyaud); audio.start(); SLONE = MediaPlayer.create(this,R.raw.sl1); SLONE.start(); if(SLONE.isPlaying()==false) { SLONE.release(); } final MediaPlayer mp = MediaPlayer.create(this, R.raw.buttonbeep); final Vibrator mVibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); Button skipButton = (Button)findViewById(R.id.skip); skipButton.setOnClickListener(new OnClickListener() { public void onClick(View v) { Intent skipIntent = new Intent(pgone.this,choose.class); startActivity(skipIntent); mp.start(); mVibrator.vibrate(500); finish(); timer.cancel(); timer.purge(); } }); } } </code></pre> <p>Page 2 is ok. Page 3 is ok. </p> <p>And here's my Page 4 i get error when going to the Fifth page.

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).
