Hi all, I have a problem then trying to put an intent with
AppWidgetManager.ACTION_APPWIDGET_PICK there is a problem somethere
inside of android AppWidget ecosystem as I can see from the logs. So
that I doing wrong?
Code:
public class NPEDemoActivity extends Activity {
private final static int HOST_CODE = 1024;
private AppWidgetHost host;
private AppWidgetManager manager;
private int PICK_WIDGET_RC = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
host = new AppWidgetHost(this, HOST_CODE);
host.startListening();
manager = AppWidgetManager.getInstance(this);
Button b = (Button)findViewById(R.id.Button01);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int nextId = host.allocateAppWidgetId();
Intent pickIntent = new Intent
(AppWidgetManager.ACTION_APPWIDGET_PICK);
pickIntent.putExtra
(AppWidgetManager.EXTRA_APPWIDGET_ID, nextId);
startActivityForResult(pickIntent, PICK_WIDGET_RC);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
}
Exception happens upon button click.
