AndroidX中ComplicationManager依赖错误及应用启动实现求助

1. 修正依赖声明 #

将应用级build.gradle中的依赖替换为Complication数据源专用的AndroidX库：

dependencies {
    implementation "androidx.wear.watchface:watchface-complications-data-source:1.2.1" // 建议使用最新稳定版本
    // 保留其他原有依赖
}

2. 替换旧版导入语句 #

将代码中基于Support库的导入全部替换为AndroidX对应包：

// 替换前
import android.support.wearable.complications.ComplicationManager
import android.support.wearable.complications.ComplicationProviderService
import android.support.wearable.complications.ComplicationData

// 替换后
import androidx.wear.watchface.complications.datasource.ComplicationProviderService
import androidx.wear.watchface.complications.data.ComplicationManager
import androidx.wear.watchface.complications.data.ComplicationData
import androidx.wear.watchface.complications.data.ComplicationData.Companion.TYPE_LAUNCH_APP

3. 调整常量引用方式 #

AndroidX中TYPE_LAUNCH_APP属于ComplicationData的伴生对象常量，需修正代码中的引用：
将ComplicationData.TYPE_LAUNCH_APP改为TYPE_LAUNCH_APP（已通过静态导入），或直接写ComplicationData.Companion.TYPE_LAUNCH_APP。

4. 验证Manifest服务配置 #

确保AndroidManifest.xml中正确声明Complication服务：

<service
    android:name=".AppLauncherComplicationProviderService"
    android:exported="true">
    <intent-filter>
        <action android:name="androidx.wear.watchface.complications.datasource.action.COMPLICATION_UPDATE_REQUEST" />
    </intent-filter>
    <meta-data
        android:name="androidx.wear.watchface.complications.datasource.SUPPORTED_TYPES"
        android:value="4" /> <!-- TYPE_LAUNCH_APP的数值为4 -->
</service>

        } else {
            complicationManager.noUpdateRequired(complicationId)
        }
    }
