错误而使用的Android SDK的Facebook照片发布在Facebook上墙
我使用的官方Android的Facebook SDK发布的照片墙上，但它崩溃签署后，同时使应用程序的权限在我的账。 我使用的Android 3.1库为这个应用程序。
I am using official android Facebook sdk for publishing photo on wall but it crashes after sign in while allowing app permission to my account. I am using android 3.1 library for this app.
下面是我使用发布的照片在墙上的code，
following is the code which i am using to publish photo at wall,
facebook.authorize(ImageCropShare.this, new String[] { "publish_stream" },
new DialogListener() {
@Override
public void onFacebookError(FacebookError e) {
// TODO Auto-generated method stub
}
@Override
public void onError(DialogError dialogError) {
// TODO Auto-generated method stub
}
@Override
public void onComplete(Bundle values) {
Bundle params = new Bundle();
params.putString(Facebook.TOKEN, values.getString(Facebook.TOKEN));
params.putByteArray("picture", data); // here data is byte array of bitmap image
try {
facebook.request("me/photos", params, "POST");
} catch (FileNotFoundException fileNotFoundException) {
// makeToast(fileNotFoundException.getMessage());
} catch (MalformedURLException malformedURLException) {
// makeToast(malformedURLException.getMessage());
} catch (IOException ioException) {
// makeToast(ioException.getMessage());
}
try {
facebook.logout(getApplicationContext());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void onCancel() {
// TODO Auto-generated method stub
try {
facebook.logout(getApplicationContext());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
以下是由我收到从位图图像的字节数组功能
following is the function by which i am getting byte array from bitmap image
public byte[] bitmapTobyte(Bitmap bitmap)
{
byte[] data = null;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
data = stream.toByteArray();
return data;
}
和以下是我的错误日志

请帮我解决这个bug在此先感谢..！
Please help me to solve this bug thanks in advance..!
我解决了我的错误，
我给＆LT;使用-SDK安卓的minSdkVersion =12/＆GT; 在我的清单文件，当时是崩溃由于的 NetworkOnMainThreadException 。
I was giving <uses-sdk android:minSdkVersion="12" /> in my manifest file, At that time it was crash due to NetworkOnMainThreadException.
谷歌之后，我发现这个execption只是抛出针对蜂窝SDK或更高版本的应用程序。
After google it i found that this execption is only thrown for applications targeting the Honeycomb SDK or higher.
所以，我只是改变了我的SDK较低级别的API，如：＆LT;使用-SDK安卓的minSdkVersion =8/＆GT; ，现在它的做工精细..
So, i just changed my SDK to lower level api, e.g: <uses-sdk android:minSdkVersion="8" />, Now its working fine..
不过，尽管如此，如果我们要使用蜂窝或更高版本的SDK，然后我们需要在单独的线程中执行所有与网络相关的任务（使用处理器，异步任务或runOnUiThread）。
But Still if we want to use Honeycomb or higher SDK then we need to perform all the network related task in separate thread (use handler,Async Task or runOnUiThread).
下面是处理与功放的好榜样;异步任务，并检查了如何使用 runOnUiThread
Here is good example of handler & Async Task and also check how to use runOnUiThread
