在我的 facebook android 应用程序中,我需要将图像从 sd 卡上传到 facebook 中的特定相册。我可以创建一个与 sd 卡文件夹同名的相册。但是在创建专辑之后它会得到一个异常——android.os.NetworkOnMainThreadException。这是我的代码-
private void uploadImage()
{
String ExternalStorageDirectoryPath = Environment
.getExternalStorageDirectory()
.getAbsolutePath();
String targetPath = ExternalStorageDirectoryPath + "/Friends/";
File targetDirector = new File(targetPath);
File[] files = targetDirector.listFiles();
for (File file : files)
{
Bitmap bmp = BitmapFactory.decodeFile(file.getAbsolutePath());
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
final byte[] data = stream.toByteArray();
facebook.authorize(MainActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener()
{
@Override
public void onComplete(Bundle values)
{
if(verify)
{
myAlbumId = createAlbumName();
verify=false;
}
uploadImagesToAlbum(data, myAlbumId);
}
@Override
public void onFacebookError(FacebookError error)
{
Toast.makeText(MainActivity.this, "FaceBook Error", Toast.LENGTH_LONG).show();
}
@Override
public void onError(DialogError e)
{
Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_LONG).show();
}
@Override
public void onCancel()
{
Toast.makeText(MainActivity.this, "Canceled", Toast.LENGTH_LONG).show();
}
});
}
}
private String createAlbumName()
{
Bundle params = new Bundle();
params.putString("name", "Friends");
params.putString("message", "My Test Album Description Here");
mAsyncRunner.request("me/albums", params, "POST", new SampleUploadListener(), null);
String response = "";
String albumId = "";
try {
response = facebook.request("https://graph.facebook.com/me/albums",params,"POST");
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
albumId=Util.parseJson(response).getString("id");
} catch (FacebookError e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return albumId;
}
private void uploadImagesToAlbum(byte[] byteArray, String albumId)
{
if ( albumId == null ) {
albumId = "me";
}
Bundle params = new Bundle();
params.putByteArray("picture", byteArray);
mAsyncRunner.request(albumId+"/photos", params, "POST", new SampleUploadListener(), null);
}
这是我的日志-
