[英]Android Google Map V2 - “unfortunately App has stopped”
I'm trying to display google map on my android app when user click on a button. 当用户单击按钮时,我正在尝试在我的Android应用上显示Google地图。 when I click the button the app stops.No error in the code. 当我单击按钮时,应用程序停止。代码中没有错误。 I believe I've done everything right 1-I got the API KEY 我相信我做对了一切1-我知道了API KEY
2-I added the Google_Play_Services_lib.jar to the dependencies folder 2-我将Google_Play_Services_lib.jar添加到依赖文件夹
3-added extra support tool 3添加了额外的支持工具
4-included the permissions,my key to the manifest 4-包含权限,清单的我的钥匙
5-added fragment to my xml layout fie for the map 5-将片段添加到地图的xml布局文件中
please help I feel like I've read and watched every tutorial there is...nothing worked! 请帮忙,我觉得我已经阅读并观看了所有教程,但没有任何效果!

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// TODO Auto-generated method stub
}
public void view_map(View view) {
Intent intent = new Intent(this, Mymap.class);
startActivity(intent);
// Do something in response to button
}
}
have you tried to look at this SO post? 您是否尝试查看此SO帖子? seems like changing the xml to match your class name fixes most issues. 似乎更改xml以匹配您的类名可以解决大多数问题。
Google Maps V2 - Error inflating class Fragment Google Maps V2-错误放大类片段
If you are targeting api level 8 and above then you can't use a simple Activity
, you need to extend FragmentActivity
. 如果您的目标是api级别8和更高级别,则不能使用简单的Activity
,则需要扩展FragmentActivity
。
I'm guessing this is the reason you have the inflating problem. 我猜这是您出现充气问题的原因。
And you are missing this meta-data
section in you manifest file: 而且您在清单文件中缺少此meta-data
部分:
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
place it next to your's api key meta-data
section. 将其放在您的api键meta-data
部分旁边。
I did use Google Maps v2 API for android in my recent app development and I cannot even start to tell you how long it took to just have the map show up on the screen. 我在最近的应用程序开发中确实使用了Android的Google Maps v2 API,甚至无法开始告诉您将地图显示在屏幕上需要多长时间。 I eventually got it working and I have the project on Github which you can look through and make sure to read through all the important files like Manifest and res/ folder; 我最终成功了,我在Github上有一个项目,您可以浏览并确保通读所有重要文件,例如Manifest和res /文件夹;
