[Q] MapView-No Map Display

I am new to SW development with Android.
Trying to have a MapView object in my display. Code is straightforward below. But for some reason when i launch the application i do not see any map but rather the grey grid.
I have looked at many posts on the internet and i understand that it is either an INTERNET permission (which is included in my coe) or a wrong apiKey. I have gone through the apiKey several time.
Am not sure what can be wrong. Any help would be great. Thanks, Lebnen.

Dont see your manifest. Is it a dev map key ? Is the application debuggable in the manifest ?
Sent from my Nexus One using XDA App

1. What do you mean by dev map key? Am using the debug.keystory MD5 hash that I feed into the google page http://code.google.com/android/add-ons/google-apis/maps-api-signup.html to get the apiKey.
2. The application is debbugable in the manifest.

Ok i see your files on computer now (not on android application on my nexus one)
replace com.google.android.maps.MapView by com.test.testmap.testMapActivity

If I replace it in main.xml the application crashes; in the manifest it does not compile
Help!

the:
<uses-permission android:name="android.permission.INTERNET" />
you have to put on <manifest>, not on <application>
like
<manifest ...>
<application ...>
<uses-library android:name="com.google.android.maps" />
.
.
.
</application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
Other thing that I'm not totally right if it's correct:
I don't know if this is correct, but for me, only worked when I create a new Android Project with Target on Google API's. Didn't work with Android 2.2 + map.jar.
Did you create with Android X.X or Google API ?

I have tried to put the INTERNET permission inside and outside the application. It does not make a difference.
I am building a Google API application.

It worked.
Weird. I had to add
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
in <manifest> outside of <application> and did it through the "Permissions" tab in Eclipse.
Thanks.

Interesting, because I thought that the "ACCESS_FINE_LOCAT ION" is used only when you try to use something with location, such as get location, distance between locations, etc..., I thought that it's not necessary when you only want to show the map
Good to know, thank you

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:

[Q] ListView with BaseAdapter not showing

Hi I have used ListFragment and simple ArrayAdapter quite often. And now I want to try some more by customizing BaseAdapter. But something happened, the List is not showing at all. I don't have any error (the Logcat also saying there're no error). But I debug it, and found out that getView() in my customized BaseAdapter is not called. I wonder why?
Here's the snippet:
#favorite_list_layout
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"

android:layout_height="wrap_content" />
</LinearLayout>
#FavoritesFragment
Code:
public class FavoritesFragment extends ListFragment {
[user=439709]@override[/user]
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//... setting variable favList, and this code is working. favList is not empty and there're no error
setListAdapter(new FavoriteAdapter(getActivity(), favList));
}
}
FavoriteAdapter, extends BaseAdapter
Code:
public class FavoriteAdapter extends BaseAdapter {
private Context ctx;
List<DMapData> list;
public FavoriteAdapter(Context context, List<DMapData> list) {
this.ctx = context;
this.list = list;
System.out.println("constructor executed!");
}
[user=439709]@override[/user]
public int getCount() {
return list.size();
}
[user=439709]@override[/user]
public Object getItem(int i) {
return list.get(i);
}
[user=439709]@override[/user]
public long getItemId(int i) {
return i;
}
[user=439709]@override[/user]
public View getView(int position, View convertView, ViewGroup parent) {
System.out.println("GetView is executed"); //But it's not.
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.favorite_list_item, parent, false);
}
TextView favText = (TextView) rowView.findViewById(R.id.favorite_text);
TextView detailsText = (TextView) rowView.findViewById(R.id.favorite_text_details);
DMapData data = list.get(position);
System.out.println("DMapData from List");
favText.setText(data.getName());
detailsText.setText(data.getDetails().length()<=50? data.getDetails() : data.getDetails().substring(0, 51).concat("..."));
System.out.println("At the end of getView()");
return rowView;
}
}
Thanks

The id of the ListView has to be a special one so that the ListFragment can find it:
Code:
android:id="@android:id/list"

Hmm...
I have tried to change the id like your code. But, still not shown up. Is there anything I should do with my ListFragment?

Do you inflate your layout?
Code:
[user=439709]@override[/user]
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_layout, container, false);
}
I always set the adapter in onCreate but there shouldn't be a difference.
Your layout looks like that now, right?
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<ListView
android:id="android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
EDIT: Oh, add an orientation to the LinearLayout or replace it by a RelativeLayout.
And change the ListView heigth to match_parent.

Yupz. But still no different.
Here's my changed code. I have changed not using my customized adapter again, but instead using SimpleAdapter.

Code:

What do you think?

Do you inflate your layout?
Code:
[user=439709]@override[/user]
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_layout, container, false);
}
I always set the adapter in onCreate but there shouldn't be a difference.
Your layout looks like that now, right?
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<ListView
android:id="android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
EDIT: Oh, add an orientation to the LinearLayout or replace it by a RelativeLayout.
And change the ListView heigth to match_parent.

Yupz. But still no different.
Here's my changed code. I have changed not using my customized adapter again, but instead using SimpleAdapter.
/res/layout/favorite_list_layout.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

public class AllFragment extends ListFragment {

super.onCreate(savedInstanceState);
//TODO get All Data
//Let's just adopt Favorite List Adapter for now

Try this layout:
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/list"
android:layout_alignParentTop="true"
android:fastScrollEnabled="true" />
<ProgressBar
android:id="@android:id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
style="?android:attr/progressBarStyle" />
</RelativeLayout>
It's working for me.
Did you try to write all entries to the logs? Do you get an output?

You know what? This is really make me laugh all the time, that it's because what I think is right but actually not. The list that I provided for my ListView is actually empty. Your layout tell me, because there's always the progressbar. Thank you very much for your help. :highfive:

Welcome.
I'm glad that you solved that because it began to drive me crazy. :laugh:

@JoshieGeek
consider using Log
Log.i("class/functionName","message you want to display");

It will be easy to debug

Yes its quite noticeable
As he was saying he could not see error in Log while debugging. My advice to use log was for his future projects.

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 :::
THE APPWIDGET.CLASS:
Code:
package com.example.increment;
import android.app.IntentService;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
public class AppWidget extends AppWidgetProvider {
int c = 0;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if (intent.getAction() == null)
context.startService(new Intent(context, ToggleService.class));
else
super.onReceive(context, intent);
}
[user=439709]@override[/user]
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
// TODO Auto-generated method stub
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
private class ToggleService extends IntentService {
public ToggleService() {
super("AppWidget$ToggleService");
// TODO Auto-generated constructor stub
}
[user=439709]@override[/user]
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
ComponentName me = new ComponentName(this, AppWidget.class);
AppWidgetManager mgr = AppWidgetManager.getInstance(this);
mgr.updateAppWidget(me, buildUpdate(this));
}
private RemoteViews buildUpdate(Context context) {
// TODO Auto-generated method stub
RemoteViews rm = new RemoteViews(context.getPackageName(),
R.layout.widget);
c++;
String s = String.valueOf(c);
rm.setTextViewText(R.id.t2, s);
Intent i = new Intent(this, AppWidget.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
rm.setOnClickPendingIntent(R.id.t2, pi);
return rm;
}
}
}
THE WIDGET.XML
Code:
