我正在使用官方的Android Facebook sdk在墙上发布照片，但在登录后崩溃，同时允许我的帐户获得应用程序权限。 我正在为这个应用程序使用android 3.1库。
以下是我用于在墙上发布照片的代码，
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();
}
}
});
以下是我从位图图像
获取字节数组的函数public byte[] bitmapTobyte(Bitmap bitmap)
{
byte[] data = null;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
data = stream.toByteArray();
return data;
}
以下是我的错误日志

请提前感谢帮我解决这个问题..！
答案 0 :(得分：2)
我解决了我的错误，
我在我的清单文件中提供了<uses-sdk android:minSdkVersion="12" />，当时由于NetworkOnMainThreadException而崩溃了。
google之后，我发现只针对Honeycomb SDK或更高版本的应用程序抛出了此execption。
所以，我只是将我的SDK更改为较低级别的api，例如：<uses-sdk android:minSdkVersion="8" />，现在工作正常..
但是如果我们想要使用Honeycomb或更高版本的SDK，那么我们需要在单独的线程中执行所有与网络相关的任务（使用处理程序，Async Task或runOnUiThread）。
以下是handler & Async Task的一个很好的示例，还会检查如何使用runOnUiThread
