如何从Android将任何文件或图像上传到谷歌云存储

我想把文件从安卓设备上传到谷歌云存储。为此，我使用JSON API在谷歌云中创建了一个项目，并创建了与之相关的bucket。然后创建服务帐户密钥，即p12文件

但后来，他坚持在Android编程中编写代码

private static String uploadFile(RichMedia media) {
DefaultHttpClient client = new DefaultHttpClient();
Bitmap bitmap = BitmapUtils.getBitmap(media.getLocalUrl());
HttpPost post = new HttpPost(GCS_ROOT + media.getLocalUrl() + "_" + System.currentTimeMillis());
if(media.getType() == RichMedia.RichMediaType.PICTURE) {
    post.setHeader("Content-Type", "image/jpeg");
} else {
    post.setHeader("Content-Type", "video/mp4");
}
post.setHeader("Authorization", "AIzaSyCzdmCMwiMzl6LD7R2obF0xSgnnx5rEfeI");
//post.setHeader("Content-Length", String.valueOf(bitmap.getByteCount()));
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();

try {
    post.setEntity(new StringEntity(new Gson().toJson(byteArray).toString()));
    HttpResponse response = client.execute(post);
    BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    String eachLine = null;
    StringBuilder builder = new StringBuilder();
    while ((eachLine = reader.readLine()) != null) {
        builder.append(eachLine);
    }
    L.d("response = " + builder.toString());
    JSONObject object = new JSONObject(builder.toString());
    String name = object.getString("name");
    return  name;
} catch (IOException e) {
    L.print(e);
} catch (JSONException e) {
    L.print(e);
}
return null;

}

你可以从这个代码中删除leran
