安卓：java.lang.NoClassDefFoundError：com.google.andro

我的活动代码

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文件的代码

   <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>

和明显的代码

<?xml version="1.0" encoding="utf-8"?>

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

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<permission

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.testmap.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="API_KEY_FROM_GOOGLE_API_CONSOLE" />
</application>

Answer 1:

1.尝试删除这一行：

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

从XML文件中的片段，它不应该存在。

2.更改此权限：

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

为此：

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

如果com.example.mapdemo是你的项目包。 如果不将其更改为你的项目包在此权限和这样的：

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

Answer 2:

你复制谷歌，播放services.jar，而不是链接到谷歌播放services_lib项目？

认真遵守本： https://developers.google.com/maps/documentation/android/start

Answer 3:

尝试从Android SDK中导入项目：/演员/谷歌/ google_play_services_libproject / google_play_services_lib到您的工作空间在内部消除您的应用程序添加任何文件夹/ lib目录库。

后为此，添加他们在您的： 项目>属性>安卓>库添加
