settings中獲取流量統計 aidl對外提供

需要提供和原生設置流量一致的數據，所以通過aidl對外提供接口

封裝對象

package com.traffic;

import android.os.Parcel;
import android.os.Parcelable;

/**

 */
public class AppInfoBean implements Parcelable {
    private String name;
    private String total;
    private int uid;
    public AppInfoBean() {

    }
    public AppInfoBean(int uid, String name, String total) {
        super();
        this.uid = uid;
        this.name = name;
        this.total = total;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getTotal() {
        return total;
    }

    public void setTotal(String total) {

    }

    public int getUid() {

    }

        this.uid = uid;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {
        parcel.writeInt(uid);
        parcel.writeString(name);
        parcel.writeString(total);
    }

    // 添加一個靜態成員,名爲CREATOR,該對象實現了Parcelable.Creator接口
    public static final Creator<AppInfoBean> CREATOR
            = new Creator<AppInfoBean>() {
        @Override
        public AppInfoBean createFromParcel(Parcel source) {
            // 從Parcel中讀取數據，返回Person對象
            return new AppInfoBean(source.readInt()
                    , source.readString()
                    , source.readString());
        }

        @Override
        public AppInfoBean[] newArray(int size) {
            return new AppInfoBean[size];
        }
    };
}

aidl 提供接口

// AppInfoBeana.aidl
package com.traffic;

// Declare any non-default types here with import statements

parcelable AppInfoBean;

// IMyAidlInterface.aidl
package com.traffic;

// Declare any non-default types here with import statements
import com.tricheer.traffic.AppInfoBean;
interface IMyAidlInterface {
   List<AppInfoBean> getNowData();
   List<AppInfoBean> getHistoryData(long start,long end);
}
