所以，这就是我得到的logcat信息.该应用程序仍然可以运行，但是我想知道出现此错误的原因. 我不明白为什么要得到这个，所以我什至都不知道该怎么问.

很抱歉忘记粘贴Main活动.

---

I am sorry for forgetting paste the Main activity.

第27行是

public class MainActivity extends AppCompatActivity  {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

super.onCreate(savedInstanceState);是第27行.

super.onCreate(savedInstanceState); is the line 27.

推荐答案

很抱歉回答这个老问题，但是我在我的项目中解决了此异常.

Sorry to answer this old question,but i solved this exception in my project.

我认为导致异常的原因是，我们在创建活动时使用的是活动的上下文.

I think what leads to the exception is we are using the context of our activity when it is creating.

我的代码是这样的:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        regToWx();
}


private void regToWx(){
    IWXAPI  api;
    api = WXAPIFactory.createWXAPI(this, Constants.WX_APP_ID, true);
    api.registerApp(Constants.WX_APP_ID);
    String text = "123";
    WXTextObject textObj = new WXTextObject();
    textObj.text = text;

    WXMediaMessage msg = new WXMediaMessage();
    msg.mediaObject = textObj;
    msg.description = text;

    SendMessageToWX.Req req = new SendMessageToWX.Req();
    req.scene = SendMessageToWX.Req.WXSceneSession;
    req.transaction = String.valueOf(System.currentTimeMillis());
    req.message = msg;

    api.sendReq(req);
}

因为regToWx方法需要通过this创建上下文，但是我认为不能(在某些方面)在onCreate方法中使用上下文.所以我只是将其放在线程中，然后问题就解决了.

As the regToWx method need to create something by this which is the context,but i think the context can not be used(in some ways) inside onCreate method. So I just put it in a thread and then the problem is solved.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        new Thread(new Runnable() {
        @Override
        public void run() {

            regToWx();
        }
    }).start();

}

因此，尝试找出使用onCreate方法中的context做过的事情，将这些代码放到其中，或者只是使代码异步.

So try to find out what you have done with your context in onCreate method, put these code out of the it or just make the code asynchronous.
