我在企业微信中，申请了企业微信授权登录，

问题1.请问在申请时需要填写的 “应用签名”  从哪里获取到

问题出现步骤

1.我暂时把“应用签名” 输入入我生成的签名文件中 SHA1 的值，获取到 schema  如下图1

2.图2是我生成后的结果

3.从  “我的企业”  中获取 “企业ID” 作为CORPID

4.从 “应用管理” -》“自定义应用” 中获取 AgentId

5.在android studio 中设置好签名，如下：

signingConfigs {
    release {
        keyAlias 'key0'
        keyPassword '123456'
        storeFile file('test.jks')
        storePassword '123456'
    }
}

6.调用企业微信sdk的原码如下

public class MainActivity extends Activity {

    private static final String TAG = "MainActivity";
    private static String CORPID = "ww36cf81984eefac88"; //个人授权app 管理端后台单位信息中查找
    private static String AGENTID = "1000002"; // 管理端 单位应用中对应应用的AgentId
    private static String SCHEMA = "wwauth36cf81984eefac88000002 "; // 管理端后台-单位应用-授权登录-Android 中的schema

    IWWAPI iwwapi;
    int stringId;
    WWMediaMergedConvs wmc = new WWMediaMergedConvs();
    WWMediaMessage.WWMediaObject mo;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        stringId = getApplicationInfo().labelRes;
        iwwapi = WWAPIFactory.createWWAPI(this);
        iwwapi.registerApp(SCHEMA);


        findViewById(R.id.btut6).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                intIDs();
                //sso登陆
                final WWAuthMessage.Req req = new WWAuthMessage.Req();
                req.sch = SCHEMA;
                req.appId = CORPID;
                req.agentId = AGENTID;
                req.state = "dd";
                req.scopes = new ArrayList<String>() {{
                    add("snsapi_base");
                }};
                iwwapi.sendMessage(req, new IWWAPIEventHandler() {
                    @Override
                    public void handleResp(BaseMessage resp) {
                        if (resp instanceof WWAuthMessage.Resp) {
                            WWAuthMessage.Resp rsp = (WWAuthMessage.Resp) resp;
                            String t = "";
                            if (rsp.errCode != WWAuthMessage.ERR_OK) {
                                Toast.makeText(MainActivity.this, t = "登陆失败," + rsp.errCode + " " + rsp.errMsg,
                                        Toast.LENGTH_SHORT).show();
                            } else {
                                Toast.makeText(MainActivity.this, t = "登陆成功 code：" + rsp.code,
                                        Toast.LENGTH_SHORT).show();
                            }
                        }
                    }
                });
            }
        });

       
    }

    private void intIDs() {
        iwwapi.registerApp(SCHEMA);
    }

}
