ANDROID: the application just "stop unexpectedly" when run on the
phone
When I run my application on the emulator, it run right and no problem
happens. But when I run it on the phone, a problem appear "stop
unexpectedly".
In my application:
The main activity (Background) can exchange to 4 activities:
LivingRoom, DiningRoom, Wc, Garage. The problem "stop unexpectedly"
just happens when i try to go to the DiningRoom activity.
This is my code :
1.Background
[CODE]
package com.example.background;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import at.abraxas.amarino.Amarino;
public class BackgroundActivity extends Activity {
private Button Wc, Dining_Room, Living_Room, Garage;
private Intent D_intent, L_intent, G_intent, W_intent;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//Amarino.connect(this, DEVICE_ADDRESS);
Living_Room = (Button) findViewById(R.id.living);
//Living_Room.setBackgroundColor(Color.TRANSPARENT);
Living_Room.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view) {
L_intent = new Intent(view.getContext(),
LivingRoom.class);
startActivityForResult(L_intent, 0);
}
});
Dining_Room = (Button) findViewById(R.id.dining);
// Dining_Room.setBackgroundColor(Color.TRANSPARENT);
Dining_Room.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view) {
D_intent = new Intent(view.getContext(),
DiningRoom.class);
startActivityForResult(D_intent, 0);
}
});
Wc = (Button) findViewById(R.id.wc);
//Wc.setBackgroundColor(Color.TRANSPARENT);
Wc.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
W_intent = new Intent(view.getContext(),
Wc.class);
startActivityForResult(W_intent, 0);
}
});
Garage = (Button) findViewById(R.id.garage);
// Garage.setBackgroundColor(Color.TRANSPARENT);
Garage.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
G_intent = new Intent(view.getContext(),
Garage.class);
startActivityForResult(G_intent, 0);
}
});
}
}
[/CODE]

Force finishing activity com.example.background/.BackgroundActivity
I also try to wrote another application similar to the above
application. But I just have only 1 sub activity: DiningRoom, then it
ran well on the phone.
Please give me some suggestions. Thanks so much
