Android关于java.lang.NoClassDefFoundError问题

解决方案：检查在AndroidManifest.xml里package路径是否正确，android:name=".xxx"是否正确

还极有可能是没有添加附加的library（在地图开发中）

<uses-library android:name="com.google.android.maps" />

在Manifest中添加文件的位置规则：

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

<manifest>

??? <uses-permission />
??? <permission />
??? <permission-tree />
??? <permission-group />
??? <instrumentation />
??? <uses-sdk />
??? <uses-configuration />??
??? <uses-feature />??
??? <supports-screens />??
??? <compatible-screens />??
??? <supports-gl-texture />??

??? <application>

??????? <activity>
??????????? <intent-filter>
??????????????? <action />
??????????????? <category />
??????????????? <data />
??????????? </intent-filter>
??????????? <meta-data />
??????? </activity>

??????? <activity-alias>
??????????? <intent-filter> . . . </intent-filter>
??????????? <meta-data />
??????? </activity-alias>

??????? <service>
??????????? <intent-filter> . . . </intent-filter>
??????????? <meta-data/>
??????? </service>

??????? <receiver>
??????????? <intent-filter> . . . </intent-filter>
??????????? <meta-data />
??????? </receiver>

??????? <provider>
??????????? <grant-uri-permission />
??????????? <meta-data />
??????? </provider>

??????? <uses-library />

??? </application>

</manifest>
