微信登录
注意:
1.在你的包名相应目录下新建一个wxapi目录，并在该wxapi目录下新增一个WXEntryActivity类，并实现IWXAPIEventHandler
2.包名，appid要和微信开发者申请的一致
3.在build.gradle下配置
signingConfigs {
debug {
storeFile file('C:\\Users\\hp\\AndroidStudioProject\\demo.key.jks')
storePassword '111111'
keyPassword '111111'
keyAlias = 'key0'
}
}
包名修改完成后，对应的 applicationId " "中的包名也要修改
1.配置文件
<activity
android:name="com.personal.revenant.baoyouqian.wxapi.WXEntryActivity"
android:configChanges="keyboardHidden|orientation|screenSize"
android:exported="true"
android:launchMode="singleTop"
android:screenOrientation="portrai
android:theme="@android:style/Theme.Translucent.NoTitleBar" />
2.全局配置
package com.personal.revenant.baoyouqian.app;
import android.app.Application;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import com.personal.revenant.baoyouqian.utlis.Constant;
import com.tencent.mm.opensdk.constants.ConstantsAPI;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
public class Myapp extends Application {
public static Myapp instance;
public static Context mContext;
public static IWXAPI iwxapi;
@Override
public void onCreate() {
super.onCreate();
this.mContext = this;
instance = this;
registToWX();
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// 将该app注册到微信
iwxapi.registerApp(Constant.WEIXINAPPID);
}
}, new IntentFilter(ConstantsAPI.ACTION_REFRESH_WXAPP));
}
private void registToWX() {
//AppConst.WEIXIN.APP_ID是指你应用在微信开放平台上的AppID，记得替换。
iwxapi = WXAPIFactory.createWXAPI(this, Constant.WEIXINAPPID, false);
// 将该app注册到微信
iwxapi.registerApp(Constant.WEIXINAPPID);
}
public static Context getContext() {
return mContext;
}
}
3.调用接口
if (!Myapp.iwxapi.isWXAppInstalled()) {
toast("您的设备未安装微信客户端");
} else {
SendAuth.Req req = new SendAuth.Req();
req.scope = "snsapi_userinfo";
// req.state = "wechat_sdk_demo";
Myapp.iwxapi.sendReq(req);
}
4.回调
public class WXEntryActivity extends Activity implements IWXAPIEventHandler {

private String GetCodeRequest = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code";

微信分享
1.调用接口

textObj.webpageUrl = url;

req.scene = SendMessageToWX.Req.WXSceneSession;
//req.userOpenId =;
Myapp.iwxapi.sendReq(req);
}
public static String buildTransaction(final String type) {
return (type == null) ? String.valueOf(System.currentTimeMillis()) : type + System.currentTimeMillis();
}
2.工具类
public class Util {

public static byte[] bmpToByteArray(final Bitmap bmp, final boolean needRecycle) {
ByteArrayOutputStream output = new ByteArrayOutputStream();
bmp.compress(CompressFormat.PNG, 100, output);

try {

} catch (Exception e) {
