我正在创建一个应用程序，使用SQLite数据库在地图上显示附近的地方。当我运行代码时，它将在 MainActivity.java:33 上提供 Java.lang.NoClassDefFoundError 。这是setContentView(R.layout.activity_main);
我检查了我的清单，然后我意识到了
` <meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />`
此行未添加到清单中且targetsdk版本为8.当我添加此行并将targetsdk版本更改为16时，将显示错误“错误：错误：找不到与给定匹配的资源name（在'value'处，值为'@ integer / google_play_services_version'）。“但是当我将android值更改为4030500时，它会运行但崩溃。现在我不明白它崩溃的原因。请帮忙。这是我的清单代码，mainActivity.java类和log cat。
