目标
在我的相机应用程序中,我想让用户与预先格式化的文本和用户的Facebook墙上的描述共享图片。
的 INTRO
我用Google搜索了很多内容并跟随了#34;非常棒的" facebook-getting-started,尝试了许多事情,为!!天!! ...还没有找到完全可行的解决方案。
至少我认为我得到了一些观点:
伟大的Android Intent action_send效果不错但不选择适用于文字或图片的脸谱,不适用于两者(!!),请参阅here
applicationID,hashxxx以及将Android应用程序链接到Facebook登录所需的一切,我真正理解并且不想做,完成和最后工作的所有事情(thanx facebook所有这些sh * t !!)
与facebook分享可以完成(见here):
3A。使用Facebook应用程序(安装在设备中)
3B。使用登录会话(如果未安装Facebook应用程序)
Facebook希望我们使用其SDK,它是非常[b | s]的广告,但我能忍受它。
案例3a - facebook建议我们使用shareDialog,并且使用代码片段和建议的示例进行大量的战斗! - 我已经能够做到了,但是如果facebook应用程序不是,我也需要它已安装(案例3b。)
案例3b - facebook建议使用" ugly" feedDialog作为后备(见here)
6A。 feedDialog需要登录才能正常...
6B。似乎feedDialog无法分享本地图像,我真的不明白为什么... here Facebook指南只谈及" URL"对于"图片"关键字...
5C。然后我认为我必须使用Request,我尝试实现它但没有发生任何事情,我想我错过了一些东西......没有找到有用的参考文献(=工作实例)。
来自SO和developers.facebook的 CODE SNIPPETS 复制/粘贴/编辑
Sharedialog和会话管理,以防未安装facebook app IT' S WORKING
/**
* share image with facebook, using facebook sdk
* @param pathToImage
*/
private void shareWithFacebook(String pathToImage) {
Log.i("SHARE", "share with facebook");
if (FacebookDialog.canPresentShareDialog(getApplicationContext(), FacebookDialog.ShareDialogFeature.SHARE_DIALOG)) {
// Publish the post using the Share Dialog
Log.i("SHARE", "share with ShareDialog");
FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this)
.setCaption("Sharing photo taken with MyApp.")
.setName("Snail Camera Photo")
.setPicture("file://"+pathToImage)
.setLink("http://myapplink")
.setDescription("Image taken with MyApp for Android")
.build();
uiHelper.trackPendingDialogCall(shareDialog.present());
} else {
// maybe no facebook app installed, trying an alternative
// here i think i need a session
if (Session.getActiveSession() != null && Session.getActiveSession().isOpened()) {
publishFeedDialog(pathToImage);
} else {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
List<String> permissions = new ArrayList<String>();
permissions.add("publish_actions");
session.openForRead(new Session.OpenRequest(this)
.setPermissions(permissions)
.setCallback(mFacebookCallback));
} else {
Session.openActiveSession(this, true, mFacebookCallback);
}
}
}
}
private Session.StatusCallback mFacebookCallback = new Session.StatusCallback() {
public void call(final Session session, final SessionState state, final Exception exception) {
if (state.isOpened()) {
String facebookToken = session.getAccessToken();
Log.i("SHARE", facebookToken);
Request.newMeRequest(session, new Request.GraphUserCallback() {
public void onCompleted(GraphUser user, com.facebook.Response response) {
publishFeedDialog(MP.LAST_TAKEN_FOR_GALLERY);
}
}).executeAsync();
}
}
};
feedDialog片段,适用于文本字段,链接和远程网址,但使用&#34;适用于本地图片使用&#34; file://...&#34;也不是&#34; file:///..."。错误消息:picture URL is not properly formatted
。
private void publishFeedDialog(String pathToImage) {
Bundle params = new Bundle();
params.putString("name", "myapp Photo");
params.putString("caption", "Sharing photo taken with myapp.");
params.putString("description", "Image taken with myapp for Android");
params.putString("link", "http://myapp.at.playstore");
params.putString("picture", "file://"+pathToImage);
WebDialog feedDialog = (
new WebDialog.FeedDialogBuilder(EnhancedCameraPreviewActivity.this,//getApplicationContext(),
Session.getActiveSession(),
params))
.setOnCompleteListener(new OnCompleteListener() {
public void onComplete(Bundle values,
FacebookException error) {
Log.i("SHARE", "feedDialog.onComplete");
if (error == null) {
// story is posted
final String postId = values.getString("post_id");
if (postId != null) {
Toast.makeText(getApplicationContext(),
"Posted story, id: "+postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
} else {
// Generic, ex: network error
Toast.makeText(getApplicationContext(),
"Error posting story",
Toast.LENGTH_SHORT).show();
}
}
})
.build();
feedDialog.show();
}
另一个尝试,使用请求,它说:
照片上传问题。错误= {HttpStatus:403,errorCode:200, errorType:OAuthException,errorMessage:(#200)需要扩展 permission:publish_actions}
我尝试在上面的会话管理中添加publish_actions权限,也许我想念一些......
private void publishFeedDialog(String pathToImage) {
Request request=Request.newPostOpenGraphObjectRequest(
Session.getActiveSession(),
"PhotoUpload",
"myApp Photo Upload",
"file://"+pathToImage,
"http://myapp.at.playstore",
"Image taken with myApp for Android",
null,
uploadPhotoRequestCallback);
request.executeAsync();
}
最后尝试请求,绝对没有任何反应,无论是否有&#34;图片&#34;关键字。
private void publishFeedDialog(String pathToImage) {
Bundle parameters = new Bundle();
parameters.putString("message", "Image taken with myApp for Android");
parameters.putString("picture", "file://"+pathToImage);
parameters.putString("caption", "myApp Photo");
Request request = new Request(Session.getActiveSession(), "/me/feed", parameters, null);
// also tried: Request request = new Request(Session.getActiveSession(), "/me/feed", parameters, com.facebook.HttpMethod.POST);
request.executeAsync();
}
的问题
-1-我的1分6分中是否有一些错误?
-2-我可以使用FeedDialog分享本地图片吗?
-3-如果没有,如何安装facebook app?
非常感谢!
答案 0 :(得分:1)
我遇到同样的问题,但我有一个解决方法。
这会将图片上传到用户个人资料并将其张贴在他/她的墙上,之后您可以根据需要获取该网址:
private void uploadPicture(final String message, Session session) {
Request.Callback uploadPhotoRequestCallback = new Request.Callback() {
@Override
public void onCompleted(com.facebook.Response response) {
if (response.getError() != null) {
Toast.makeText(getActivity(), "Failed posting on the Wall", Toast.LENGTH_LONG).show();
return;
}
Object graphResponse = response.getGraphObject().getProperty("id");
if (graphResponse == null || !(graphResponse instanceof String) ||
TextUtils.isEmpty((String) graphResponse)) {
Toast.makeText(getActivity(), "Failed uploading the photo\no respons", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getActivity(), "Succsefully posted on the facebook Wall", Toast.LENGTH_LONG).show();
}
}
};
// Execute the request with the image and appropriate message
Request request = Request.newUploadPhotoRequest(session, profileBitmap, uploadPhotoRequestCallback);
Bundle params = request.getParameters();
params.putString("message", message);
request.executeAsync();
}
当你没有APP时启动facebook登录,它更简单,我使用以下代码片段在facebook按钮上调用facebook SDK:
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.faceBookButton:
if (((imagePath != null && !imagePath.equals("")) || (message != null && !message.equals("")))) {
Session session = Session.getActiveSession();
if (!session.isOpened() && !session.isClosed()) {
session.openForPublish(new Session.OpenRequest(this)
.setPermissions(Arrays.asList("public_profile", "publish_actions"))
.setCallback(statusCallback));
} else {
if (profileBitmap != null) {
uploadPicture(message, session);
} else {
publishFeedDialog(message);
}
}
} else {
Toast.makeText(getActivity(), getString(R.string.checkin_fail), Toast.LENGTH_SHORT).show();
}
break;
}
}
在我的情况下,publishFeedDialog接受您要传递的消息,而不是图像,但这并不重要。无论如何,它打开了Facebook的消息对话框,我还没有找到从EditText小部件传递预定义消息的方法。
