Is uploading videos from an SD Card to Facebook possible with the Facebook SDK?
我想通过我的Android应用在Facebook上分享视频。
我通过我的应用程序贴了一堵墙，而且工作正常。现在我想在Facebook上分享一个视频。所以我尝试了下面的代码。
Facebook facebook;
String FB_APP_ID=APP_ID;
byte[] data = null;
Uri uri=Uri.fromFile(new File(Environment.getExternalStorageDirectory(),"filename.mp4"));
String dataPath = uri.getPath();
String dataMsg = "Testing video sharing from my app";
Bundle param;
facebook = new Facebook(FB_APP_ID);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
InputStream is = null;
try {
is = new FileInputStream(dataPath);
data = readBytes(is);
param = new Bundle();
param.putString("message", dataMsg);
param.putByteArray("video", data);
mAsyncRunner.request("me/videos", param, "POST", new SampleUploadListener(), null);
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
读取字节方法是
public byte[] readBytes(InputStream inputStream) throws IOException {
// this dynamically extends to take the bytes you read
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
// this is storage overwritten on each iteration with bytes
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
// we need to know how may bytes were read to write them to the byteBuffer
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
byteBuffer.write(buffer, 0, len);
}
// and then we can return your byte array.
return byteBuffer.toByteArray();
}
SampleUploader类是
public class SampleUploadListener extends BaseRequestListener {
public void onComplete(final String response, final Object state) {
try {
// process the response here: (executed in background thread)
Log.d("Facebook-Example", "Response: " + response.toString());
JSONObject json = Util.parseJson(response);
final String src = json.getString("src");
// then post the processed result back to the UI thread
// if we do not do this, an runtime exception will be generated
// e.g. "CalledFromWrongThreadException: Only the original
// thread that created a view hierarchy can touch its views."
Example1.this.runOnUiThread(new Runnable() {
public void run() {
mText.setText("Hello there, video has been uploaded at \n" + src);
}
});
}
catch (JSONException e) {
Log.w("Facebook-Example", "JSON Error in response");
}
catch (FacebookError e) {
Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());
}
}
}
它无效，在logcat中显示以下警告。
