I'm trying to run the example from NDK package on a AT91SAM9M10-EKES board running Android 2.1
The activity fails.
This is what I get in the logcat, Can someone please guide me with this ?

you hadnt built the library(.so) file of the project thats why you are getting this error, try to build the project with help of android-ndk http://developer.android.com/sdk/ndk/index.html and cygwin http://www.cygwin.com/

I am trying to run my application that uses LibGDX on Andriod using the NetBeans IDE.
However the game crashes for some reason, I just got the "This application have stopped to work" message when I try to run the application. Everything works great on PC, so apparently I have missed something in the andriod set up. Setting up an andriod project on NetBeans is not an documented area and things seem to be different on Eclipse.
If someone have manged to run LibGDX on andriod by setting up the project in Netbeans, please share the steps you did.
Some code, I doubt that would help through:
public class Game extends AndroidApplication {
public void onCreate (android.os.Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initialize((ApplicationListener) new game.GameSystem(new Size2i(100, 100)), false);
}
}
The debug output I get is the following:
D/dalvikvm( 478): Trying to load lib /data/data/com.RPGGame/lib/libgdx.so 0x40515708
D/dalvikvm( 478): Added shared lib /data/data/com.RPGGame/lib/libgdx.so 0x40515708

So basically I cannot cast game.GameSystem to ApplicationListener. Even if GameSystem implements ApplicationListener.
GameSystem works as intended on PC, all I did for the Andriod project was to put that code in the main file.
Okay, I solved it now, turned out I used the wrong version of game.GameSystem.
I have a activity which uses a listview element as follows
public class List1 extends Activity
{
Context context=this;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
try{
//DB
final SQLiteDatabase db;
db = openOrCreateDatabase(
"Secret.db"
, SQLiteDatabase.CREATE_IF_NECESSARY
, null
);
db.setVersion(1);
db.setLocale(Locale.getDefault());
db.setLockingEnabled(true);
Cursor cur = db.query("tbl_user",null,null,null,null,null,null);
//DB Over
ListView listView = (ListView) findViewById(R.id.mylist);
listView.setTextFilterEnabled(true);
final String[] values = new String[50];
int i=0;
while(cur.moveToNext())
{
values[i]=Integer.toString(cur.getInt(0))+":"+cur.getString(1)+":"+cur.getString(2);
i++;
}
cur.close();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item,values);
listView.setAdapter(adapter);
listView.setVisibility(0);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position,long id)
//public void onItemClick(ListView<?> listview, View view, int position,long id)
{
try
{
Intent i=new Intent(List1.this,Form1.class);
i.putExtra("uid","85");
startActivity(i);
finish();
}
catch(Exception e)
{
String insert2="insert into login values("+"\""+e.toString()+"\""+");";
db.execSQL(insert2);
}
}
});
db.close();
//required
}
catch(Exception e)
{
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();}
}
}
This is my listview.xml file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView>
</RelativeLayout>
This is my list_item.xml file which has the required textview
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/tv1"
android:padding="10dp"
android:background="#drawable/textview1"
style="#style/textview_text"
android:textSize="16dp">
</TextView>
But the ListView is not working. I mean after coming to this activity the app is showing error showing "APP_NAME is stopped unexpectedly". The same code works for one or two times and then shows the above error continuously after that. May I kno why is it happening?

i think your adapter should know which textViewResourceId it should use.
So try this out: ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item, R.id.tv1,values);
Change this to
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
this
<ListView
android:id="#+id/mylist"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
And why do you need listView.setVisibility(0)?
final String[] values = new String[50];
int i=0;
while(cur.moveToNext())
{
values[i]=Integer.toString(cur.getInt(0))+":"+cur.getString(1)+":"+cur.getString(2);
i++;
}
cur.close();
Starting from the this spinet of code.
When the db.query returns you should rewind the cursor before starting to use it in the while loop. What if the query returns more the 50 results? Your app will crash with ArrayOutBoundException

google maps : 4.5.1
Various crashes occur when embedding the google maps component into an android application. I'm connecting to a router via Wi-Fi for internet access. The stand-alone google maps app seems to work fine. To re-produce, start the maps app and begin scrolling around.
Will fail within a couple of minutes, occasionally on start-up (in setContentView). Most of the errors are when drawing tiles in google code. Sometimes just an Android SEGV.
NOTE : I've tested the same app on the Android developer phone 2 (os 1.6), and it works fine.

Basically, lots of bad things start happening...
The ZT-180 does not have Google Maps, AFAIK.
This is my first Android app and I've encountered an exception when trying to use the ListPreference. The application loads along with the preferences... but when i touch the ListPreference entry the applications "stops unexpectedly".
Settings.java
public class Settings extends PreferenceActivity {

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.addPreferencesFromResource(R.layout.settings);
}
}

I fixed it... I kept on trying and, at the end, it turns out that I cannot use an integer-array as the entryValues Source. I just changed that integer-array to a string-array and got it working.
If there's a way to use integer-array as the source for entryValues please comment.
I've been searching for a similar solution to what you are looking for, agreeing that you should be able to use an Integer array to read from and store an integer result.
A solution to this problem I found was at http://kvance.livejournal.com/1039349.html, which I found to be useful.
It doesn't quite solve the problem the way I was thinking or that way I think you want it to, instead you still specify your initial / selection values with a String array although when the ListPreference saves it back to the SharedPreferences it saves as an Integer instead of a String (doing the conversion when the user selects it), removing the need to have to convert it possibly many times throughout your application when accessing the preference value.
I am new to android. I would like to ask you some question.
When I calling new activity from main activity by commands
Intent myIntent = new Intent(v.getContext(), PolarView.class);
//startActivityForResult(myIntent, 0);
startActivityForResult(myIntent, 0);
finish();
then in new activity I can't do any actions, e.g. such as button click
Both
Button btnSeven = (Button) this.findViewById(R.id.btn7);
btnSeven.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
InputStr = InputStr + "7";
InputViewField.setText(InputStr);
}
});
}
and
public void btn7_click(View v) {
InputStr = InputStr + "7";
InputViewField.setText(InputStr);
}
having defined android:onClick="btn7_click" in activity`s layout
where InputViewField is EditText object
In the first case new activity does not start, in the second case when I press this button, aplication crashes.
could you please help me?
Here is some last peace of logcat after change
StartActivityForResult()
to
StartActivity()
