Android微信第三方登录

1.跟老大拿到审核通过的AppID和Appkey.

2.Manifest.xml中加入权限（这里有多余的权限，如果你是负责整个app的开发，放心，多出的权限的后面你也是会用到的）：

<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<!-- 第三方登录的权限 -->
<uses-permission-sdk-23 android:name="android.permission.aad" />

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission
    android:name="android.permission.WRITE_APN_SETTINGS"
    tools:ignore="ProtectedPermissions" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

3.在Manifast.xml下的application下加入（.wxapi.WXEntryActivity前面多一个字母都不行，照搬过去就行，一定要听踩过坑的人）：

<activity
    android:name=".wxapi.WXEntryActivity"
    android:exported="true"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" />

4.在工程中单独创建一个名字为wxapi的包，然后建立一个名字叫WXEntryActivity的Activity：然后检查WXEntryActivity的包名，一定是在工程包名的后面！！！比如我工程的包名是（AndroidManifest.xml的左上角）：

package="com.example.administrator.yezi">

那我的新建的WXEntryActivity的包名就一定是：

package com.example.administrator.yezi.wxapi;










public class WXEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {}

5.这里分为两种登录，A:直接微信登录  B：获取用户信息登录

A1:

package com.example.administrator.yezi.wxapi;








 

public class WXEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {

    private Retrofit retrofit;

        try {

    }

    }

    public void setNickname(String nickname) {
        this.nickname = nickname;
    }

    public int getSex() {
        return sex;
    }

    public void setSex(int sex) {
        this.sex = sex;
    }

    public String getLanguage() {
        return language;
    }

    public void setLanguage(String language) {
        this.language = language;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getProvince() {
        return province;
    }

    public void setProvince(String province) {
        this.province = province;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    public String getHeadimgurl() {
        return headimgurl;
    }

    public void setHeadimgurl(String headimgurl) {
        this.headimgurl = headimgurl;
    }

    public String getUnionid() {
        return unionid;
    }

    public void setUnionid(String unionid) {
        this.unionid = unionid;
    }

    public List<?> getPrivilege() {
        return privilege;
    }

    public void setPrivilege(List<?> privilege) {
        this.privilege = privilege;
    }
}

mode3，后台给你的接口文档中返回的示例，这里是我的示例:

public class User{


    /**
     * message : 请求成功
     * status : 200
     * code : 0
     * token : hpvymDJdYxvaj2cX+vM/9Q==
     * currentTime : 1524896417273
     */

    private String message;
    private int status;
    private String code;
    private String token;
    private long currentTime;

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }

    public long getCurrentTime() {
        return currentTime;
    }

    public void setCurrentTime(long currentTime) {
        this.currentTime = currentTime;
    }


}

最后：这里用的是Retrofit请求
