Android新浪微博之发送微博

发送微博主要就是调用新浪微博给的接口、调用android拍照和对拍照后的图片处理。

拍照时调用的系统接口代码是：

Intent takephoto = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takephoto, 520);

获得拍得的照片代码：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
}

下面上全部代码：
