How to start an activity after certain time period

Question

i need to start an activity from the current activity after a certain time period. I coded like below.

public class FirstActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_first);


    new Timer().schedule(new TimerTask(){
        public void run() { 
            startActivity(new Intent(FirstActivity.this, SecondActivity.class));
        }
    }, 2000); 
}

But its not working..it keeps on crashing.. Is my method correct? my manifest file is as below

`

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".FirstActivity"
        android:label="@string/title_activity_first" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".SecondActivity"
        android:label="@string/title_activity_second" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.first.FirstActivity" />
    </activity>
</application>

Answer 1

use runOnUiThread for starting activity from Timer as:

new Timer().schedule(new TimerTask(){
        public void run() { 
         FirstActivity.this.runOnUiThread(new Runnable() {
            public void run() {
            startActivity(new Intent(FirstActivity.this, SecondActivity.class));
          }
        });
       }
    }, 2000);

Give this a try. I use this for a Splash Screen in my app and works just fine. Also, as @Venture pointed out in the comment, make sure the activity is added to your manifest file.

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        Intent startActivity = new Intent(FirstActivity.this, SecondActivity.class);
        startActivity(startActivity);
        finish();
    }
}, 2000);
