照着视频敲得但运行不了，求分析代码错误啊
package com.imooc.activitydemo;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends Activity {
final String TAG = "tag";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(TAG, "MainActivity-->onCreate");
}
@Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
Log.i(TAG, "MainActivity -->onStart");
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
Log.i(TAG, "MainActivity -->onResume");
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
Log.i(TAG, "MainActivity -->onPause");
}
@Override
protected void onStop() {
// TODO Auto-generated method stub
super.onStop();
Log.i(TAG, "MainActivity -->onStop");
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Log.i(TAG, "MainActivity -->onDestroy");
}
@Override
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
Log.i(TAG, "MainActivity -->onRestart");
}
}
我用的是真机测试，run as 的时候提示有错误装不上去。但代码没有出现错误和警告啊，请问哪里错了
