从 drawable 创建文件以使用 sendbird 发送

Question

我想在 sendbird api 中使用 sendFileMessage。它需要文件值，我想使用来自 drawable（或 assets）的文件。 sendBird API

这是从 sendbird 截取的代码

Hashtable<String, Object> info = Helper.getFileInfo(getActivity(), uri);
final String path = (String) info.get("path");
File file = new File(path);
String name = file.getName();
String mime = (String) info.get("mime");
int size = (Integer) info.get("size");

sendFileMessage(file, name, mime, size, "", new BaseChannel.SendFileMessageHandler() {
    public void onSent(FileMessage fileMessage, SendBirdException e) {
        if (e != null) {
            return;
        }
        mAdapter.appendMessage(fileMessage);
        mAdapter.notifyDataSetChanged();
    }
});

这段代码运行良好，我 uri 从开放图像意图中获得。但我想用于其他目的，我想替换此代码

File file = new File(path);

变得像

File file = new File(<path or uri from drawable or assets>);

我试过 uri

Uri uri = Uri.parse("android.resource://com.package.name/raw/filenameWithoutExtension");
File file = new File(uri.getPath());

使用 inputStream

try {
    File f=new File("file name");
    InputStream inputStream = getResources().openRawResource(R.raw.myrawfile);
    OutputStream out=new FileOutputStream(f);
    byte buf[]=new byte[1024];
    int len;
    while((len=inputStream.read(buf))>0)
    out.write(buf,0,len);
    out.close();
    inputStream.close();
}
catch (IOException e){}

总是获取文件失败并且return错误代码ERR_REQUEST_FAILED 800220

你试过如下吗？

String fileName = FILE_NAME;
File cachedFile = new File(this.getActivity().getCacheDir(), fileName);

try {
    InputStream is = getResources().openRawResource(R.raw.sendbird_ic_launcher);
    FileOutputStream fos = new FileOutputStream(cachedFile);
    byte buf[] = new byte[1024];
    int len;
    while ((len = is.read(buf)) > 0)
        fos.write(buf, 0, len);
        fos.close();
        is.close();
} catch (IOException e) {
    e.printStackTrace();
}

groupChannel.sendFileMessage(cachedFile, fileName, "image/jpg", (int) cachedFile.length(), "", new BaseChannel.SendFileMessageHandler() {
    @Override
    public void onSent(FileMessage fileMessage, SendBirdException e) {
    }
});

这对我有用。
