我尝试使用Android应用谷歌地图,但我的努力是徒劳的。我甚至在Stackoverflow中遇到了同样问题的许多问题,但没有一个答案解决了我的问题。所以我再次重新提出问题,希望能解决我的问题。
我按照本教程(http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/)来设计我的应用程序。
代码: MainActivity.java
package com.example.hopemap;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.Toast;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
public class MainActivity extends Activity {
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
的Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hopemap"
android:versionCode="1"
android:versionName="1.0" >
<meta-data android:name="com.google.android.gms.version"

</activity>
</application>
</manifest>
Layout.xml

android:layout_height="fill_parent" >
<fragment

答案 0 :(得分:2)
在Application
标记
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
和
create an integer variable inside res/value folder with version of google play
例如:res / values / version.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<integer name="google_play_services_version">4030500</integer>
</resources>
答案 1 :(得分:0)
尝试从
复制version.xml文件 google-play-services_lib/res/values/version.xml
到
YourProjectName/res/values/version.xml
