用Android studio开发，在真机中运行很好，但是生成APP后却无法分享，想问一下老师，这是什么问题呢？
在日志中截的错误，E/ActivityThread: Failed to find provider info for com.tencent.mm.coolassist，
我添加了RadioButton来做判断： int selected = radioGroup.getCheckedRadioButtonId();
private void weCharShare(int selected_id) {
//Toast.makeText(this,radioButtonSelected.getText(), Toast.LENGTH_LONG).show();
WXImageObject image = new WXImageObject();
WXMediaMessage msg = new WXMediaMessage(image);
msg.mediaObject = new WXImageObject(generSpringCard());
SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = String.valueOf(System.currentTimeMillis());
req.message = msg;
req.scene = selected_id == R.id.weixin_friend ? SendMessageToWX.Req.WXSceneSession:SendMessageToWX.Req.WXSceneTimeline;
wx_api.sendReq(req);
}
