 Hi,
I had try some simply code on android. but when run on emulator. the
1st pages are fine, when click the button to second pages. it pop up
error "Sorry - The application Pages (process com.Pages) has stop
unexpectedly"

here the code:[Pages.java]

package com.Pages;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class Pages extends Activity
{
    @Override
        protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        // Watch for button clicks.
        Button goButton = (Button)findViewById(R.id.go);
        goButton.setOnClickListener(mGoListener);
    }

    private OnClickListener mGoListener = new OnClickListener()
    {
        public void onClick(View v)
        {
            Intent intent = new Intent();
            intent.setClass(Pages.this, loli.class);
            startActivity(intent);
        }
    };
}

an next pages code[loli.java]:
package com.Pages;

import android.app.Activity;
import android.os.Bundle;


/**
 * Example of removing yourself from the history stack after
forwarding to
 * another activity.
 */
public class loli extends Activity
{
    @Override
        protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.loli);
    }
}

I did't find any error on the code, is there any mistake done by me?

 Could you look at the logcat output (Eclipse > Windows > Perspective >
DDMS) or "adb logcat" from a shell? There should be a strack trace
that will tell you exactly what crashed.

For example, are you sure that the findViewById does not return null?

 Did you add your loli Activity into the AndroidManifest.xml?

 You can debug your code step by step, Maybe you can find out why.

1. Android HAL code debug

Hi guys,

I want to achieve the Camera HAL (libcamera.so), but the sequence of my
method is :
step 1: change the code
step 2: make to generate the libcamera.so
step 3: copy the libcamera.so to my sdcard
step 4: insert my sdcard to my board ,and get the log from adb .

if any wrong , repeat!!

it is very inefficient.

I have spend two days to find better method, but found nothing .If
anybody have the good mothod ,please tell me kindly .

2. ActiveRecord schema for Android

Hello!
I have to develop an Android application that will have to synchronize
on a regular basis on a distant database, and work offline most of the
time.
Consequently, I need to have the same SQLite database schema in the
application as master database.
The server is developped in Rails ( using ActiveRecord ), and have a
lot of "has_one", "has_many", "belongs_to", "has_and_belongs_to_many"
relations.
I've made some research for Android ORM, and I've found this :
 - ORMLite, but it doesn't handle "JOIN ... ON ... ", and doesn't
handle relations
 - android-active-record, but it's still in development
 - activeandroid, but the documentation isn't up to date, so I don't
know if the ActiveRecord schema is respected
 - neodatis, db4o and ammentos, but they're not using SQLite, so
synchronization would be hard
 - jooq, but the ActiveRecord isn't implemented for SQLite...

I'm a little bit disappointed, so all suggestions are welcome !

Regards,
Louis C.
