ConchJNI.RunJS是使用反射调用的js内部方法,以前发现过超过一定数额的字符就无法透传过去了.最近接华为这问题卡那不得不解决了,于是写了个拆分来处理(参考socket的方案).
首先是java端的代码:

public static void ReturnEvent(Object c) {
    String returnMsg = new Gson().toJson(c).replace("\n", "");
    if (returnMsg.length() >= 1000) {
        Debug.LogError("透传参数过长,准备拆分后发送");
        returnMsg = Base64.encodeToString(returnMsg.getBytes(StandardCharsets.UTF_8), Base64.DEFAULT).replace("\n", "");
        int max = 500;
        int len = returnMsg.length() / max;
        for (int i = 0; i < len; i++) {
            ConchJNI.RunJS("returnEvent({\"UnpackingStr\":\"" + returnMsg.substring(i * max, (i + 1) * max) + "\"})");
        }
        ConchJNI.RunJS("returnEvent({\"UnpackingStrOver\":\"" + returnMsg.substring(len * max) + "\"})");
    } else {
        ConchJNI.RunJS("returnEvent(" + returnMsg + ")");
    }
}

超过一定字符就拆分成多个base64,然后再在js里进行组装解码

static ReturnEvent(json) {
    if (json.UnpackingStr != null) {
        ScriptBridge.UnpackingStr += json.UnpackingStr;
        return;
    } else if (json.UnpackingStrOver != null) {
        ScriptBridge.UnpackingStr += json.UnpackingStrOver;
        let base = Base64.decode(ScriptBridge.UnpackingStr)
        console.log(base)
        json = JSON.parse(base);
        ScriptBridge.UnpackingStr = "";
    }
}
