MainActivity

我在mProgressDialog.show（）上遇到错误;线。所有这些都在AsyncTask中，请帮帮我。我还在Aysnctask的背景方法上执行一些上传操作

@Override
protected void onPreExecute() {
    res = null;
    count = 0;
    //mProgressDialog = ProgressDialog.show(Create_NewsFeed.this, "","Uploading image");
    mProgressDialog = new ProgressDialog(Create_NewsFeed.this);
    mProgressDialog.setMessage("Posting.. please wait...");
    mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    mProgressDialog.setMax(100);
    mProgressDialog.show();
    try {
        // creates a unique boundary based on time stamp
        boundary = "===" + System.currentTimeMillis() + "===";

        URL url = new URL(requestURL);
        httpConn = (HttpURLConnection) url.openConnection();
        httpConn.setUseCaches(false);
        httpConn.setDoOutput(true); // indicates POST method
        httpConn.setDoInput(true);
        httpConn.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
        httpConn.setRequestProperty("User-Agent", "CodeJava Agent");
        httpConn.setRequestProperty("Test", "Bonjour");
        outputStream = httpConn.getOutputStream();
        writer = new PrintWriter(new OutputStreamWriter(outputStream, charset),true);

        writer.append("User-Agent" + ": " + "CodeJava").append(LINE_FEED);
        writer.flush();
        writer.append("Test-Header" + ": " + "Header-Value").append(LINE_FEED);
        writer.flush();

    } catch (Exception e) {
        //...
    }
}

这是我的错误日志。请检查一下。

像这样调用你的api / asynctask，

this.runOnUiThread(new Runnable() {
            @Override
            public void run() {

                //api calls .. or use async task here

                                }
                        });
