Je suis en train de créer une application Android utilisant google maps. voici le code :
MapFragActivity.java
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
public class MapFragActivity extends FragmentActivity {
private GoogleMap map;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map_frag);
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
}
}
AndroidManifest.xml :
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.him.mapfrag_rnd"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

<uses-feature

<application

</intent-filter>
</activity>
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="my_api_key" />
</application>
</manifest>
activity_map_frag.xml :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"

</RelativeLayout>
lorsque j'essaie ce code, j'obtiens une erreur, voici le journal :

lorsque je fais quelques changements dans MapFragActivity.java, la carte s'affiche. voici les changements :
package com.him.mapfrag_rnd;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;
public class MapFragActivity extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_map_frag);
SupportMapFragment fragment = new SupportMapFragment();
getSupportFragmentManager().beginTransaction().add(android.R.id.content, fragment).commit();
}
}
La modification que j'ai apportée consiste à commenter le setContentView. J'ai suivi toutes les étapes requises et j'obtiens toujours une erreur. Si je décommente le setContentView(), j'obtiens à nouveau l'erreur.
S'il vous plaît, AIDEZ-MOI ! !!
