Do you use Google APIs target in an emulator?

No. How to use Google api.

[Q] ArrayAdapter and custom layout

Hi , i'm studyng android Adapter
I want create a ListView with a serie of data. Ok , the code.
Code:
/*
Activity class
*/
package it.actiondesign.android.app.userdata;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
public class UserDataActivity extends Activity {
ArrayList<UserData> allUsers = new ArrayList<UserData>();
private ListView myListView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myListView= (ListView) findViewById(R.id.datalist);
createFakeData();
int resID = R.layout.user_row;
// data_adpater = new ArrayAdapter<UserData>(this, R.layout.user_row, allUsers);
// myListView.setAdapter(data_adpater);
}
//fill ArrayList with fake data
private void createFakeData() {
UserData first = new UserData("Frank", "Smith", 30, "Chicaco");
UserData second = new UserData("Tania", "Roger", 20, "Los Angeles");
allUsers.add(first);
allUsers.add(second);
}
}
here the main.xml
Code:

I create a class of data
Code:
public class UserData {
private String name;
private String surname;
private int age;
private String from;
public UserData(String _name , String _surname, int _age, String _from){
this.name= _name;
this.surname= _surname;

this.from= _from;
}
public String getName(){
return name;
}
public String getSurname(){
return surname;
}
public int getAge(){
return age;
}
public String getFrom(){
return from;
}
}
custom layout of a single item
Code:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"

<TextView android:text="Age: "
android:id="@+id/TextView03" android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<TextView android:text=""
android:id="@+id/tAge" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:textColor="@color/red">
</TextView>
</TableRow>
</TableLayout>
In other layout a create a ArrayAdpater<String> and all was simple, but how can fill TextView (tName, tSurname, tAge, tFrom) with data.
Now I use a simple ArrayList after i load data from WebService

Depends what kind of data your are retrieving. In your layout you have 4 textview 'rows'. Maybe instead of this you could use a listview?

OK, so first of all, in your manifest, you do not need to create an intent-filter, that is just if an activity needs to be launched from another application.
Then, when you create your Intent to start the SecondActivity, do it like this:
Code:
Intent i = new Intent(this, SecondActivity.class);
// put extras and startforResult here
The Error in the logcat states that it could not find the activity, so I suppose this is why

Code:
<activity
android:name="com.example.intents.SecondActivity"
android:label="@string/app_name" >
<intent-filter>
[B]<action android:name="[COLOR="Red"]android.intent.action.SecondActivity[/COLOR]" />[/B]
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
The bold should be referencing the same intent you are trying to call. Change the red text portion above to "com.example.intents.SecondActivity" and use the same to call the intent.
example: Intent i = new Intent("com.example.intents.SecondActivity");
The red text should match each other.

Still crashing!

}
}
}
}

It is giving errors because of how you are trying to get the strings from the intent in SecondActivity.
replace what you have in your SecondActivity onCreate with the below.
Code:
Intent intent = getIntent();
Toast.makeText(this, intent.getStringExtra("str1"), Toast.LENGTH_LONG).show();
Toast.makeText(this, String.valueOf(intent.getIntExtra("age1", 0)), Toast.LENGTH_LONG).show();
Bundle bundle = intent.getExtras();
Toast.makeText(this, bundle.getString("str2"), Toast.LENGTH_SHORT)
.show();
Toast.makeText(this, Integer.toString(bundle.getInt("age2")),
Toast.LENGTH_SHORT).show();

Thank you, finally it worked :thumbup:

Widget not working

Hey, fellas.. I was learning about widgets. But I got stuck at the very beginning. I was trying to make the simplest of a widget. Firstly, I made an app, that only has one textview on it. When clicked , it shows the number of times it has been clicked. Then I tried to make a widget of the same.
But when I click over the widget, nothing happens. It just shows the initialized number '0'. The debugging goes fine. There is no ANR errors.
But I am not able to figure out the logical error. As the debugging goes alright, I don't think, the logcat will be necessary.
However, If required , I will provide it too. For now, I am uploading the AppWidget.class, widget.xml, manifest.xml, widget_provider.xml :::

2.3.3 to 4.2.2 Http Get - Help me conquer learning curve

Hey all!
New to Android but not developing. App runs great with emulator running Android 2.3.3. When I install the app to my phone (Samsung Galaxy 4S Active) runnnig Android 4.2.2, the Http Get execute command on the client does not seem to happen. I get no data back reported to my TextView.

I would post the logcat but there really is no issue at 2.3.3... just need to know what i'm missing going to 4.2.2.
Thanks in advance, I know this should be easy for you all.
