Opening a JAR

android:scrollHorizontally="false"

android:maxLines="5"

android:maxWidth="200sp"

/>

</TableRow>

<Button android:id="@+id/send"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="Send"

/>

</TableLayout>

Then, eliminate references to the removed widgets from the list of data

members and from onCreate().

Next, create a private SharedPreferences data member named prefs and set

it up in onCreate():

prefs=PreferenceManager.getDefaultSharedPreferences(this);

prefs.registerOnSharedPreferenceChangeListener(prefListener);

The aforementioned code references an prefListener object, so define it as

follows:

private SharedPreferences.OnSharedPreferenceChangeListener prefListener=

new SharedPreferences.OnSharedPreferenceChangeListener() {

public void onSharedPreferenceChanged(SharedPreferences sharedPrefs, String

key) {

if (key.equals("user") || key.equals("password")) {

resetClient();

}

}

};

Basically, when the preference changes, we want to reset our Twitter client.

This, of course, assumes we have a Twitter client hanging around, so create

a private Twitter data member named client, and add two methods to work

with it as follows:

synchronized private Twitter getClient() {

if (client==null) {

client=new Twitter(prefs.getString("user", ""),

prefs.getString("password", ""));

client.setAPIRootUrl("https://identi.ca/api");
