Question

I have an application in Android, I’ve changed the main Activity, and now nothing is showing up when I launch it. I don’t know what could be wrong. Please help.

Main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
>
<TextView  
    android:id="@+id/text1" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
 />
<Button  
android:id="@+id/btnCrash"
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/btnCrash"
/>
</LinearLayout>

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest package="gdpTesis.client" android:versionCode="1"
android:versionName="1.0" xmlns:android="http://schemas.android.com/apk/res/android">
<application android:icon="@drawable/icon" android:label="@string/app_name"
    android:name="gdpTesis.client.main.GdpTesisApplication">
    <activity android:name=".main.GdpTesisMainActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
</manifest>

The Activity

package gdpTesis.client.main;

import gdpTesis.client.R;
import android.app.Activity;
import android.os.Bundle;

public class GdpTesisMainActivity extends Activity {

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

I CAN’T BELIEVE IT! I’m with the emulator, and I don’t have an Android phone, so I expected after running the application, see it in the emulator screen, but it was locked, and it doesn’t unlock by itself, so just unlocking it with the mouse…showed the activity. sorry! and thanks!
