本答案参考通义千问

你遇到的问题是因为从 Android 12 开始，如果你的应用目标 SDK 版本是 Android 12 或更高版本，并且你的 <activity> 元素中定义了 <intent-filter>，那么你必须显式地设置 android:exported 属性。

根据你的描述，你已经为 <activity> 设置了 android:exported="true"，但仍然出现了错误。这可能是因为某些地方没有正确设置或者有其他未被注意到的 <activity> 元素。

以下是详细的解决方案：

1. 检查所有 <activity> 元素：确保每个带有 <intent-filter> 的 <activity> 都明确设置了 android:exported 属性。

2. 添加或更新 android:exported 属性：确保所有 <activity> 元素都包含 android:exported 属性。

下面是修改后的 AndroidManifest.xml 示例：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.o3dr.android.client">

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

    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

    <!-- Support devices without Bluetooth since there are other connection types -->
    <uses-feature
        android:name="android.hardware.bluetooth"
        android:required="false"/>

    <!-- Support devices without USB host mode since there are other connection types -->
    <uses-feature
        android:name="android.hardware.usb.host"
        android:required="false"/>

    <!-- Support devices that don't have location services -->
    <uses-feature
        android:name="android.hardware.location.gps"
        android:required="false"/>
    <uses-feature
        android:name="android.hardware.location.network"
        android:required="false"/>
    <uses-feature
        android:name="android.hardware.location"
        android:required="false"/>

    <application>

        <activity
            android:name="org.droidplanner.services.android.impl.ui.activity.UsbIntentReceiver"
            android:launchMode="singleInstance"
            android:noHistory="true"
            android:exported="true"
            android:excludeFromRecents="true">
            <!-- USB connection intent -->
            <intent-filter>
                <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"/>
            </intent-filter>

            <meta-data
                android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
                android:resource="@xml/device_filter"/>
        </activity>

        <service
            android:name="org.droidplanner.services.android.impl.api.DroidPlannerService"
            android:exported="true"
            android:enabled="false">

            <!-- Filter and meta data for the Tower lib runtime -->
            <intent-filter>
                <action android:name="com.o3dr.services.android.lib.model.IDroidPlannerServices" />
            </intent-filter>

            <meta-data
                android:name="com.o3dr.dronekit.android.core.version"
                android:value="@integer/core_lib_version" />
        </service>

    </application>

</manifest>

关键点：

• 确保所有带有 <intent-filter> 的 <activity> 元素都有 android:exported 属性。
• 在示例中，android:exported="true" 已经被设置在 <activity> 元素中。

通过以上步骤，你应该能够解决 android:exported 需要显式指定的问题。
