的AndroidManifest.xml /活性

@Sagar是的，AndroidManifest.xml中有一个活动。下面是代码

<activity
            android:name=".MapsActivity"
            android:label="@string/title_activity_maps">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

Answer 1

试试这个：

<activity android:name="com.yourpackagename.MapsActivity" android:label="@string/title_activity_maps"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>

让我知道这是否有效
