私はAndroidアプリに取り組んでおり、アプリからFacebookに画像を共有したいのですが、ダイアログを表示せずに、以下のように試しましたが、うまくいきません。
コード
public void postFb(){ String path = "me/feed";
AccessToken at = AccessToken.getCurrentAccessToken();
Bundle parameters = new Bundle();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Const.bmp_post.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
parameters.putByteArray("picture", byteArray);
HttpMethod method = HttpMethod.POST;
GraphRequest.Callback cb = new GraphRequest.Callback() {
@Override
public void onCompleted(GraphResponse graphResponse) {
Log.d("=======graph response=======" , graphResponse.toString());
//check graphResponse for success or failure
if(graphResponse.getError()==null){
Toast.makeText(NewPostActivity.this, "Successfully posted to Facebook", Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(NewPostActivity.this, "Facebook: There was an error, Please Try Again", Toast.LENGTH_SHORT).show();
}
}
};
GraphRequest request = new GraphRequest(at,path,parameters,method,cb);
request.setParameters(parameters);
request.executeAsync();
}
