android - Android Studio 上的 list 合并错误

Question

我基本上是在尝试从一项 Activity 转移到谷歌地图 Activity 。我将 MapsActivity 文件添加到 list 文件中，如下所示:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="mahboob.cmec">

    <uses-permission android:name="android.permission.INTERNET" />

    <!--
         The ACCESS_COARSE/FINE_LOCATION permissions are not required to use
         Google Maps Android API v2, but you must specify either coarse or fine
         location permissions for the 'MyLocation' functionality. 
    -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".menu" />
        <activity android:name=".Reference" />
        <activity android:name=".Registration" />
        <activity android:name=".RegistrationComplete" />
        <activity android:name=".electricitybill" />
        <activity android:name=".GasBill" />
        <activity android:name=".BillReport" />
        <activity android:name=".SetTarget" />
        <activity android:name=".EcoReport" />
        <activity android:name=".MapsActivity" />
        <activity android:name=".ManageContract" />
        <activity android:name=".GraphReport" />

        <!--
             The API key for Google Maps-based APIs is defined as a string resource.
             (See the file "res/values/google_maps_api.xml").
             Note that the API key is linked to the encryption key used to sign the APK.
             You need a different API key for each encryption key, including the release key that is used to
             sign the APK for publishing.
             You can define the keys for the debug and release targets in src/debug/ and src/release/. 
        -->
        <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="@string/google_maps_key" />

        <activity
            android:name=".MapsActivity"
            android:label="@string/title_activity_maps"></activity>
    </application>

</manifest>

当我运行代码时，我得到以下输出:

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed with multiple errors, see logs

我不确定问题出在哪里，我假设我需要将 MapsActivity 类添加到我已完成的 list 文件中。

Answer 1

首先，您可以尝试清理项目然后构建。如果问题没有解决，您可以尝试第二个选项。

其次，这是Android开发的一个普遍错误。如果找不到错误，则必须查看 Gradle 控制台信息。但是默认的 gradle 控制台信息很接近。你需要打开它。

1. 文件->设置
2. 构建、执行、部署 -> 编译器
3. --stacktrace --debug -> 写入命令行选项
4. 好的

然后就可以看gradle console了。您将看到更多信息。您可以在此处检测错误。
