I'm having troubles working with fragments to the 2.2 platform. I imported the android-support-v4.jar library to support fragments.
I tried to change the target to Honeycomb 3.0, and the code works. So, I wanna know if there exists a way to work with fragments on a native platform and a different way to do that with prior versions.
Here is my AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.nsy.testefragmentos"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:label="@string/app_name"
android:name=".TesteFragmentosActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="FragmentoLista" />
<activity android:name="FragmentoDetalhe" />
</application>
</manifest>
And here is my main class
package com.nsy.testefragmentos;
import android.app.Activity;
import android.os.Bundle;
public class TesteFragmentosActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
And finally, the fragment called from the main.xml file:
package com.nsy.testefragmentos;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentoLista extends ListFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return super.onCreateView(inflater, container, savedInstanceState);
}
}
when I run, the follow error appears in the logCat:
