＆＃34;课程链接失败＆＃34;在谷歌地图V2应用程序
我写了一个应用程序，它有一个Launcher活动和两个Map活动。
当我运行它时，一个Map活动就像一个梦，而另一个则与 java.lang.NoClassDefFoundError 崩溃。崩溃的人有一个＆＃34;班级的链接失败＆＃34;在我调用它之前发出警告。
我已经通过 SO 的所有适用解决方案，似乎没有任何帮助。我有：
-
检查并重新检查 Android清单，
-
完成了对 Java构建路径所做的所有建议。
-
检查了活动的所有导入（崩溃），看看在清单
中 android：minSdkVersion 之后没有实现
由于我的应用使用了 com.google.android.maps。* 类，因此我考虑使用
<uses-library android:name="com.google.android.maps" />
元素，但产生了
Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY
根据 Commonsware，3月27日＆＃39; 14 ：
＆LT;您的清单中有一个元素。任
-
不应该在那里，或
-
您正在尝试在没有的设备上安装该应用 那个图书馆。 ＆GT;
我尝试将 maps.jar 手动插入我设备的文件夹中，但这并没有消除错误。
所以这是我的代码： Launcher Activity类（称为Selector.class）：
package com.thenewboston.googlemaps;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class Selector extends Activity implements View.OnClickListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.select_activity);
Button bMain = (Button)findViewById(R.id.button1);
Button bOther = (Button)findViewById(R.id.button2);
bMain.setOnClickListener(this);
bOther.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()){
case R.id.button1:
Intent main_intent = new Intent(this,MainActivity.class);
startActivity(main_intent);
break;
case R.id.button2:
Intent other_intent = new Intent(this,OtherActivity.class);
startActivity(other_intent);
break;
}
}
}
My 2nd Map Activity名为OtherActivity.class（崩溃）：
