Question

well, almost everything is in the question, I have a problem with program which should use the sqlite, it still returns the “unexpected error”, I was just wondering do I have to start some kind of server, deamon or service?

androidManifest[ snippet ]

<activity android:name=".About">
android:label="@string/about_title" 
android:theme="@android:style/Theme.Dialog" >
</activity>
<activity android:name=".Exit">
andorid:label="@string/exit_title">    
</activity>
<activity android:name=".Options">
</activity>
<activity android:name=".Start">
</activity>
<activity android:name=".Create">
</activity>

</application>

AndroidSQLite

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sql);
TextView listContent = (TextView)findViewById(R.id.contentlist);
mySQLiteAdapter = new SQLiteAdapter(this);
mySQLiteAdapter.openToWrite();
mySQLiteAdapter.deleteAll();
mySQLiteAdapter.insert("ABCDE");
mySQLiteAdapter.insert("FGHIJK");
mySQLiteAdapter.insert("1234567");
mySQLiteAdapter.insert("890");
mySQLiteAdapter.insert("Testing");
mySQLiteAdapter.close();
mySQLiteAdapter = new SQLiteAdapter(this);
mySQLiteAdapter.openToRead();
String contentRead = mySQLiteAdapter.queueAll();
mySQLiteAdapter.close();
listContent.setText(contentRead);
}

sql.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:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/app_name"
/>
<ListView
android:id="@+id/contentlist"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>

main.xml [snippet]

<Button
android:id="@+id/where_button"
android:onClick="WhereCl"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/where_label" />

code responsible for button Where Am I?

mainActivity.java

public class MainActivity extends Activity
{


@Override
public void onCreate(Bundle savedInstanceState)

{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

View startButton = findViewById(R.id.start_button);
View whereButton = findViewById(R.id.where_button);
View aboutButton = findViewById(R.id.about_button);
View exitButton = findViewById(R.id.exit_button);

}

public void OptionsCl(View v){

startActivity(new Intent(this,Options.class));
}

public void WhereCl(View v){

startActivity(new Intent(this,AndroidSQLite.class));
}

public void StartCl(View v){

Intent idd = new Intent(this,Start.class);
startActivity(idd);
}
public void AboutCl(View v){

startActivity(new Intent(this,About.class));
}
public void ExitCl(View v){

finish();
}

}

the error I receive is similar to this which come up with unregistred action, but the action is registred [ check the code ]

it is just “the application blabla (menu.dot) has stopped unexpectedly. Please try again” Force close.

Answer 1

Android SQLite is readymade library. So you don’t need to start any Service, server or demon. Just to initiate a database class extending SQLite DatabaseHelper class and use it.

Thanks.
