I am trying to invoke a start activity or splash screen for some time (5 seconds) in my application but I am getting exception.I just want this activity to load for 5 seconds and then vanish and then main activity comes. I am new to android.Any help would be appreciated:
MY code is like this:
public class StartActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
ProgressDialog pbar=new ProgressDialog(getApplicationContext());
pbar.setMessage("Connecting...");
pbar.setCancelable(false);
pbar.show();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
final Intent mainIntent = new Intent(StartActivity.this, MainActivity.class);
StartActivity.this.startActivity(mainIntent);
StartActivity.this.finish();
}
}, 5000);
}
}
Exception I am getting is like this:

Use StartActivity.this instead of getApplicationContext() for creating ProgressDialog object like:
ProgressDialog pbar=new ProgressDialog(StartActivity.this);
