GPS状态接收器2周前停止工作

Question

我已将此BroadcastReceiver用作GPS状态接收器，以监视用户何时在顶部导航菜单中打开/关闭其位置。它在两周前突然停止工作（未调用整个接收器onReceive()方法）（可能与Android 10版本有关）。您知道什么地方可能出问题吗？

以前效果很好。

class GPSReceiver: BroadcastReceiver(){

    companion object{
        const val GPS_PAYLOAD = "gps_payload"
        const val GPS_STATE = "gps_state"
    }

    override fun onReceive(context: Context, intent: Intent) {
        App.log("IsGPSEnabled: callingonReceive")
        val action = intent.action
        if(action != null && action == LocationManager.PROVIDERS_CHANGED_ACTION){
            try {
                val locationManager = context.getSystemService(Context.LOCATION_SERVICE) as LocationManager
                val int = Intent(GPS_PAYLOAD)
                if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
                    int.putExtra(GPS_STATE, true)
                } else {
                    int.putExtra(GPS_STATE, false)
                }
                LocalBroadcastManager.getInstance(context).sendBroadcast(int)
            } catch (ex: Exception) {
                App.log("IsGPSEnabled: $ex")
            }
        }

    }
}

AndroidManifest：

<!-- GPS status receiver -->
        <receiver android:name=".services.GPSReceiver"
            android:exported="false">
            <intent-filter>
                <action android:name="android.location.PROVIDERS_CHANGED" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </receiver>

Android 8.0+清单接收器已过时

在活动中注册对象BroadcastReceiver监视意图：

registerReceiver(gpsStatusReceiver, IntentFilter("android.location.PROVIDERS_CHANGED"))

您必须像这样更新您的xml部分：

<receiver
    android:name=".Util.GpsReceiver"
    android:enabled="true"> <!-- do this and try again -->
    <intent-filter>
         <action android:name="android.location.PROVIDERS_CHANGED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

不要忘记此权限：

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