使用Android Facebook SDK在Facebook墙上发布照片时出错
作者：互联网
我正在使用官方android Facebook sdk在墙上发布照片,但登录后崩溃,同时允许我的帐户允许应用程序使用.
我正在为此应用程序使用android 3.1库.
以下是我用来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 one rror(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功能
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

请提前帮助我解决此错误.
解决方法:
我解决了我的错误,
我正在给< uses-sdk android：minSdkVersion =“ 12” />在我的清单文件中,当时由于NetworkOnMainThreadException而崩溃.
在google之后,我发现只对针对Honeycomb SDK或更高版本的应用程序抛出此执行.
所以,我只是将SDK更改为较低级别的api,例如：< uses-sdk android：minSdkVersion =“ 8” /> ;,现在可以正常使用了. 但是仍然,如果我们要使用Honeycomb或更高版本的SDK,则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,异步任务或runOnUiThread). 这是handler & Async Task的很好的例子,并检查如何使用runOnUiThread
