    <p>I am a beginner in Android. I am trying to start a new activity via an intent inside an onclick event. This works fine in emulator. But when I try it in a real device it doesn't work and the application goes to the main screen again. No errors are shown in the logcat. </p> <p>This is where I call the <code>startActivity</code> method. </p> <pre><code>relativeAbout.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub try { Class OurClass = Class .forName("com.wad.tourismguide.AboutCity"); Intent newIntent = new Intent(getApplicationContext(), OurClass); newIntent.putExtra("name", name); newIntent.putExtra("detail", detail); newIntent.putExtra("image", main); startActivity(newIntent); System.out.println("intent starting"); } catch (ClassNotFoundException e) { // TODO: handle exception e.printStackTrace(); } } }); </code></pre> <p>The new activity is shown below. </p> <pre><code> public class AboutCity extends Activity { TextView cityName; ImageView image; TextView detailText; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.aboutcity); cityName = (TextView)findViewById(R.id.tvDetailCityName); image = (ImageView)findViewById(R.id.ivDetailImage); detailText = (TextView)findViewById(R.id.tvDetailText); String name = getIntent().getStringExtra("name"); System.out.println("city name"+ name); String detail = getIntent().getStringExtra("detail"); System.out.println("city detail"+ detail); Bitmap b= (Bitmap)getIntent().getParcelableExtra("image"); System.out.println(detail); cityName.setText(name); detailText.setText(detail); image.setImageBitmap(b); } } </code></pre> <p>As I explained earlier, this works fine in the emulator. But it doesn't work in the real device. I can't find where I am going wrong. Can someone please help me with this?</p>

    1. COPost the error logcat too. And, is there a reason for using this to declare the class: `Class OurClass`?

    2. COAre you receiving classNotFound Exception?... if your com.wad.tourismguide.AboutCity package and class names are perfect than it should work... Here you aer catching ClassNotFoundException So if the class path is wrong it will throw the exception and simply stays in the MainActivity...

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).
