Question

通过调用startActivity(intent)在Android中使用Office应用程序（包括Word，Excel）打开文档时，Office for Android会显示以前显示的文档，而Google doc会显示正确的文档。

我该如何解决这个问题？

文档由Word 2016和Excel 2016（Windows）创建，可以从Google Drive中打开而不会出现任何错误。我设置我的代码中有intent.setDataAndType(uri, "application/vnd.ms-excel");和intent.setDataAndType(uri, "application/msword");。

以下是测试中的代码。

private class AsyncXlsLoader extends AsyncTask<String, Void, Integer> {
    private final ProgressDialog dialog = new ProgressDialog(getContext());
    private File tempFile;

    @Override
    protected void onPostExecute(Integer result) {
        super.onPostExecute(result);
        dialog.dismiss();
        if (result == 0) {
            try {
                Intent target = new Intent(Intent.ACTION_VIEW);
                Intent intent = Intent.createChooser(target, "Open File");
                intent.setAction(android.content.Intent.ACTION_VIEW);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                Uri uri = FileProvider.getUriForFile(getContext(), "com.mydomain.fileprovider", tempFile);
                intent.setDataAndType(uri, "application/vnd.ms-excel");
                intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                startActivity(intent);
            } catch (Exception e) {
                Toast.makeText(getContext(), e.toString(),
                Toast.LENGTH_SHORT).show();
            }
        } else {
            Toast.makeText(getContext(), " No data!",
            Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        dialog.setMessage("Downloading " + xlsfile + "...");
        dialog.show();
    }

    @Override
    protected Integer doInBackground(String... params) {
        Integer result = new Integer(0);
        URL u;
        xlsDir = getContext().getFilesDir();
        try{
            u = new URL(params[0]);
            HttpURLConnection conn = (HttpURLConnection) u.openConnection();
            conn.connect();
            // Read the stream
            tempFile = new File(xlsDir + "/xlsxfiles/", tempXlsName);
            DeleteFile(tempFile, tempXlsName);
            if (tempFile.getParentFile().mkdirs()) {
                tempFile.createNewFile();
            }
            FileOutputStream fos = new FileOutputStream(tempFile);
            InputStream is = u.openStream();
            byte[] b = new byte[1024];
            int length = 0;
            while ((length = is.read(b)) != -1) {
                fos.write(b,0, length);
            }
            fos.flush();
            fos.close();
            is.close();
            conn.disconnect();
            return 0;
        }
        catch(MalformedURLException nameOfTheException){
            u = null;
            return -1;
        }
        catch (Throwable t){
            t.printStackTrace();
            return -1;
        }
    }
} // End AsyncXlsLoader

使用startActivity打开文档（意图） - 打开错误的文档
