Hey all,
I am trying to use the GData libs on android. I have created a Java
project in eclipse that runs perfectly. However, whenever I try to
create an android project, I get a conversion failed error, due to a
class being included twice. I think this is more likely something to
do with my GData build having two jars, both of which are required,
but which re-declare the same class. I would love any help - below are
all project details.
This is definitely something specific to android, but as it seems that
I may have to modify the GData source a bit to get it to work, I was
hoping someone could give a workaround.
Thanks,
hamilton
Code:
package org.test.documents;
import java.net.URL;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import com.google.gdata.client.calendar.CalendarService;
import com.google.gdata.data.calendar.CalendarEntry;
import com.google.gdata.data.calendar.CalendarFeed;
public class Sample extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String out = "";
try {
CalendarService myService = new CalendarService(
"exampleCo-exampleApp-1.0");
myService.setUserCredentials("[email protected]",
"crabpot9");
URL feedUrl = new URL(
"http://www.google.com/calendar/feeds/default/allcalendars/
full");
CalendarFeed resultFeed = myService.getFeed(feedUrl,
CalendarFeed.class);
out += "Your calendars:\n\n";
for (int i = 0; i < resultFeed.getEntries().size();
i++) {
CalendarEntry entry =
resultFeed.getEntries().get(i);
out += "\t" + entry.getTitle().getPlainText() +
"\n";
}
} catch (Exception e) {
out = "No good";
}
TextView tv = (TextView)findViewById(R.id.text);
tv.setText(out);
tv.invalidate();
}
}
Jars added:
gdata-calendar-2.0
gdata-calendar-meta-2.0
gdata-core-1.0
google-collect-1.0-rc1
