Question

我的活動代碼

package com.example.testmap;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import com.google.android.gms.maps.SupportMapFragment;

public class MainActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

xml文件代碼

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_marginRight="150dp"
        class="com.google.android.gms.maps.SupportMapFragment" />

</RelativeLayout>

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="17" />

<uses-feature
    android:glEsVersion="0x00020000"

Answer 1

1.嘗試刪除此行：

class="com.google.android.gms.maps.SupportMapFragment"

從XML文件中的片段，它不應該存在。

2.更改此權限：

<permission
android:name="android.os.Bundle.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />

對此：

<permission
android:name="com.example.mapdemo.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />

如果com.example.mapdemo是您的項目包。 如果沒有在此權限中將其更改為您的項目包，則：

<uses-permission android:name="com.example.mapdemo.permission.MAPS_RECEIVE" />

Answer 2

您是否復制了google-play-services.jar而不是鏈接到google-play-services_lib項目？

請仔細閱讀： https ： //developers.google.com/maps/documentation/android/start

Answer 3

嘗試將項目從android sdk： / extras / google / google_play_services_libproject / google_play_services_lib導入您的工作區，而無需在您的應用程序中添加文件夾/ lib中的任何lib。

執行此操作后，將它們添加到： project> properties> android> libs add中
