Javascript Android Base64字符串不显示在Web视图上

我正在将此Base64字符串发送到javascript，并希望在webview的文本区域中显示，但未成功，这是字符串：

RK1SACAYMAAAAAAAF6AAAAA/AFEAMUAXQEAABPE0BKABZGXUDLAFFBZXUCOAFZCXUA+AFtiXUBaAGPg XUAKAGFKXUBYZMXUBEAIFKXUA7AJRNXUBGALDXYDTABNKRICZAC9YXYBGADVFXYBXAJDNxYCH AJ9KXYBAAN9SXUA1ACBHV0BCAGZIV4ZADRBUQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

另外，当我在一行硬编码这个字符串时，它会正确地显示在web视图上。。 硬编码单行字符串：

String bsiso1 = "Rk1SACAyMAAAAAF6AAAA/AFEAMUAxQEAAABpE0BkABZgXUDLAFBZXUCOAFZcXUA+AFtiXUBaAGPgXUAkAGfkXUBYAHZmXUBEAIFkXUA7AJRnXUBGALRtXYDTABNKRICzAC9YXYBGADVfXYBxAJdnXYChAJ9kXYBaAN9sXUA1ACbhV0BCAGziV4AzADRbUQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA";

这是我的代码：

 public void showDialog(String dialogMsg){
        browser.loadUrl("javascript:test(\""+bsiso+"\")");
        Log.d("Bluetooth", "Bluetooth imei" + bsiso);
 }  

这是我的方法：

private void ReceiveCommand(byte[] data)
{
    if((data[0]=='F')&&(data[1]=='T'))
    {
        switch(data[4])
        {
        case CMD_CAPTUREHOST:
            {
                int size=(byte)(data[5])+((data[6]<<8)&0xFF00)-1;
                if(data[7]==1)
                {
                    memcpy(mMatData,0,data,8,size);
                    mMatSize=size;
                    if(mMatData[0]==3){
                         bsiso=Base64.encodeToString(mMatData,0,mMatSize/*378*/,Base64.DEFAULT);
                        mEditText.setText(bsiso);
                        SaveTextToFile(bsiso);
                        AddStatusList("Capture Succeed");
                    }else{
                         bsiso=Base64.encodeToString(mMatData,0,378,Base64.DEFAULT);
                        mEditText.setText(bsiso);
                        SaveTextToFile(bsiso);
                        AddStatusList("Capture Succeed");
                    }

                }
                else
                    AddStatusList("Capture Fail");
            }
            break;
        case CMD_GETSN:
            {
                int size=(byte)(data[5])+((data[6]<<8)&0xFF00)-1;
                if(data[7]==1)
                {
                    byte[] snb=new byte[32];
                    memcpy(snb,0,data,8,size);
                    String sn = null;
                    try {
                        sn = new String(snb,0,size,"UNICODE");
                    } catch (UnsupportedEncodingException e) {
                        e.printStackTrace();
                    }
                    AddStatusList("SN:"+sn);
                }
                else
                    AddStatusList("Get SN Fail");   
            }
            break;
        }
    }
}

private void ReceiveCommand（字节[]数据）
{
如果（（数据[0]='F'）&&（数据[1]='T'））
{
开关（数据[4]）
{
案例CMD\U CAPTUREHOST：
{
int size=（字节）（数据[5]）+（（数据[6]）问题在于换行符破坏了javascript代码。请从字符串中删除EOL，或在html代码中以单独的行或段落显示字符串

请注意，这不会在任何支持javascript的浏览器中编译（您可以在Chrome控制台或其他地方进行测试）：
