小编and*_*per的帖子

我在project.prperties下面的行中没有注释

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

工作进展,它工作正常.

但是当我添加android-support-v4.jar库时,导出已签名的应用程序项目时出错

Launch canceled!
 Proguard returned with error code 1. See console
 Note: there were 316 duplicate class definitions.

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>

和清单代码

    android:minSdkVersion="9"
    android:targetSdkVersion="17" />

    android:glEsVersion="0x00020000"

我使用Google Maps Android v1 API创建了我的应用程序的第一个版本.但现在,当我发布第二版的应用程序时,Google地图停止了工作.我认为这是因为它被弃用了.

所以现在我正在尝试使用链接创建示例Android应用程序以使用Google Map

但是我正在低于力量关闭错误
