微信android sdk 能否一次发送多张图片？
WXImageObject imgObj = new WXImageObject();
imgObj.setImagePath(path);
WXMediaMessage msg = new WXMediaMessage();
msg.mediaObject = imgObj;
Bitmap bmp = BitmapFactory.decodeFile(path);
Bitmap thumbBmp = Bitmap.createScaledBitmap(bmp, THUMB_SIZE, THUMB_SIZE, true);
bmp.recycle();
msg.thumbData = Util.bmpToByteArray(thumbBmp, true);
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("img");
req.message = msg;
req.scene = SendMessageToWX.Req.WXSceneTimeline ;
api.sendReq(req);
以上代码可以分享一张图片到微信朋友圈，但是如果 想要一次分享多张图片怎么办啊

不能，至少目前这个ＳＤＫ版本是不能处理多个图片。SDK没有混淆，通过观看，它支持
public static final int TYPE_UNKNOWN = 0;
public static final int TYPE_TEXT = 1;
public static final int TYPE_IMAGE = 2;
public static final int TYPE_MUSIC = 3;
public static final int TYPE_VIDEO = 4;
public static final int TYPE_URL = 5;
public static final int TYPE_FILE = 6;
public static final int TYPE_APPDATA = 7;
public static final int TYPE_EMOJI = 8;
SDK 通过Bundle来传递数据，用 <key,value> 记录每种数据类型，并且都是单条的记录，如图片数据 WXImageObject ：
paramBundle.putByteArray("_wximageobject_imageData", this.imageData);
paramBundle.putString("_wximageobject_imagePath", this.imagePath);
paramBundle.putString("_wximageobject_imageUrl", this.imageUrl);
只有单一的 imageData ，死心吧。
不过，网上有个方法是通过系统的“分享”来调用微信，下面是我写的代码测试有效，不过这种方法还得手工在微信里面操作，适用范围太小：
private void shareMultiplePictureToTimeLine(File... files) {
Intent intent = new Intent();
ComponentName comp = new ComponentName("com.tencent.mm",
"com.tencent.mm.ui.tools.ShareToTimeLineUI");
intent.setComponent(comp);
intent.setAction(Intent.ACTION_SEND_MULTIPLE);
intent.setType("image/*");
ArrayList<Uri> imageUris = new ArrayList<Uri>();
for (File f : files) {
imageUris.add(Uri.fromFile(f));
}
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);
startActivity(intent);
}
// 遍历 SD 卡下 .png 文件通过微信分享
File root = Environment.getExternalStorageDirectory();
File[] files = root.listFiles(new FileFilter() {
@Override
public boolean accept(File pathname) {
if (pathname.getName().endsWith(".png"))
return true;
return false;
}
});
shareMultiplePictureToTimeLine(files);
咪咕吃屁屁
