Splash.java的第三十行是：
```
Bmob.initialize(this,"abaaf362bc8f971c2fac1dda83407c35");
```
源代码如下：
```
package com.example.myapp.activity;
import android.content.Intent;
import android.os.Bundle;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import com.example.myapp.MainActivity;
import com.example.myapp.R;
import java.util.Timer;
import java.util.TimerTask;
import cn.bmob.v3.Bmob;
import cn.bmob.v3.BmobUser;
public class Splash extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
//延时操作
Timer timer = new Timer();
timer.schedule(timetast, 2000);
Bmob.initialize(this,"abaaf362bc8f971c2fac1dda83407c35");
}
TimerTask timetast = new TimerTask() {
@Override
public void run() {
// startActivity(new Intent(Splash.this, MainActivity.class));
//如果已经登陆，跳转到主界面，若没有登陆，跳转到登陆界面
BmobUser bmobUser = BmobUser.getCurrentUser(BmobUser.class);
if (bmobUser!=null){
startActivity(new Intent(Splash.this,MainActivity.class));
finish();
}else
//没有登陆则显示登陆界面
startActivity(new Intent(Splash.this,Login.class));
finish();
}
};
}
```
在Manifest中应该也配置了：
```
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<!--允许联网 -->
<uses-permission android:name="android.permission.INTERNET" />

<activity android:name=".activity.Login" />
<activity android:name=".activity.Register" />

```
实在是不知道如何解决，请求大佬们解答！谢谢！！！
