因此,我在主屏幕上有一个按钮,单击该按钮会将用户带到地图视图。但是,每次我单击它时,应用程序都会崩溃。
我在 4.1.1 上从我的 GS3 运行它
map_screen.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
MapScreenActivity.java
package com.example.poopify;
import android.app.Activity;
import android.os.Bundle;
public class MapScreenActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_screen);
}
}
然后是我的 manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.poopify"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk

android:targetSdkVersion="14" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.example.poopify.permission.MAPS_RECEIVE"/>
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyBUIxDObzLKAfFrg04tPc78LBU1zkzZi6w" />
<activity
android:name="com.example.poopify.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

</activity>
<activity android:name="com.example.poopify.MainScreen" >
</activity>
<activity
android:name="com.example.poopify.MapScreenActivity"
android:label="@string/title_activity_map_screen" >
</activity>
</application>
</manifest>
这是我的 logcat,但不知道该怎么做:
