我想为我的Android手机学习一些编程。 我成功地做了你好世界的应用程序。 现在我想尝试在这里找到的mapview:http://developer.android.com/resources/tutorials/views/hello-mapview.html
我的代码如下:
package com.example.hellomapview;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.ZoomControls;
import com.google.android.maps.*;
public class HelloMapView extends MapActivity {
/** Called when the activity is first created. */
LinearLayout linearLayout;
MapView mapView;
ZoomControls mZoom;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
linearLayout = (LinearLayout) findViewById(R.id.zoomview);
mapView = (MapView) findViewById(R.id.mapview);
mZoom = (ZoomControls) mapView.getZoomControls();
linearLayout.addView(mZoom);
setContentView(R.layout.main);
}
protected boolean isRouteDisplayed() { return false;}
}
我正在使用eclipse并且我已经正确安装了SDK和AVD但是只要我在eclipse中运行>运行它就开始了:
[2010-01-15 12:27:03 - HelloMapView]New emulator found: emulator-5554
[2010-01-15 12:27:03 - HelloMapView]Waiting for HOME ('android.process.acore') to be launched...
[2010-01-15 12:27:46 - HelloMapView]HOME is up on device 'emulator-5554'
[2010-01-15 12:27:46 - HelloMapView]Uploading HelloMapView.apk onto device 'emulator-5554'
[2010-01-15 12:27:46 - HelloMapView]Installing HelloMapView.apk...
The emulator comes up and I see my droid phone ready to load the HelloMapView app..but then it dies with the following:
[2010-01-15 12:27:51 - HelloMapView]Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY
[2010-01-15 12:27:51 - HelloMapView]Please check logcat output for more details.
[2010-01-15 12:27:52 - HelloMapView]Launch canceled!
我从未做过任何Android类型的开发,而且我来自C#背景,所以我的java是iffy ......但有没有人看到我可能会丢失的任何东西?
答案 0 :(得分:3)
我的猜测是你创建了一个不包含Google API的模拟器。
如果您启动tools/android
,您会在可用的套餐中看到例如“SDK平台Android 1.5,API 3”和“Google API by Google Inc. Android API 3”。
如果您想使用地图,则需要安装Google API包,并在创建虚拟设备时使用该包。
