有一个演示apk（java开发）我需要其中一个功能，大致如下：

    public void wxOnAuth(String str) {  
       // str。obj 。obj2 参数已知  
        String queryParameter = Uri.parse(str).getQueryParameter("code");  
        String obj = this.appData.get("_wxapi_sendauth_req_state").toString();  
        String obj2 = this.appData.get("_mmessage_appPackage").toString();  
        Intent intent = new Intent();  
        intent.setClassName(obj2, obj2 + ".wxapi.WXEntryActivity");  
        Bundle bundle = new Bundle();  
        bundle.putString("_wxapi_sendauth_resp_state", obj);  
        bundle.putString("_wxapi_sendauth_resp_token", queryParameter);  
        String str2 = null;  
        bundle.putString("_wxapi_baseresp_transaction", str2);  
        bundle.putString("_wxapi_sendauth_resp_lang", "zh_CN");  
        bundle.putInt("_wxapi_command_type", 1);  
        bundle.putString("_wxapi_sendauth_resp_country", "CN");  
        bundle.putString("wx_token_key", "com.tencent.mm.openapi.token");  
        bundle.putString("_wxapi_sendauth_resp_url", str + "&state=" + obj);  
        bundle.putInt("_wxapi_baseresp_errcode", 0);  
        bundle.putString("_wxapi_baseresp_errstr", str2);  
        bundle.putString("_wxapi_baseresp_openId", str2);  
        intent.putExtras(bundle);  
        intent.putExtra("_mmessage_sdkVersion", 620954624);  
        intent.putExtra("_mmessage_appPackage", "com.tencent.mm");  
        intent.putExtra("_mmessage_content", (String) null);  
        intent.putExtra("_mmessage_checksum", a((String) null, 620954624, "com.tencent.mm"));  // 这里调用的a方法，不过返回结果是固定的（参数固定）  
        intent.putExtra("_message_token", (String) null);  
        intent.addFlags(268435456).addFlags(134217728);  
        startActivity(intent);  
        finish();  
    }  
    public byte[] a(String str, int i, String str2) {  
        StringBuffer stringBuffer = new StringBuffer();  
        if (str != null) {  
            stringBuffer.append(str);  
        }  
        stringBuffer.append(i);  
        stringBuffer.append(str2);  
        stringBuffer.append("mMcShCsTr");  
        return c(stringBuffer.toString().substring(1, 9).getBytes()).getBytes();  
    }  

    public final String c(byte[] bArr) {  
        char[] cArr = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};  
        try {  
            MessageDigest instance = MessageDigest.getInstance("MD5");  
            instance.update(bArr);  
            char[] cArr2 = new char[(r3 * 2)];  
            int i = 0;  
            for (byte b : instance.digest()) {  
                int i2 = i + 1;  
                cArr2[i] = cArr[(b >>> 4) & 15];  
                i = i2 + 1;  
                cArr2[i2] = cArr[b & 15];  
            }  
            return new String(cArr2);  
        } catch (Exception e) {  
            return null;  
        }  
    }
