我是新的android工作室程序员，当我在模拟器中尝试它的工作没有任何问题，但在我的手机或其他手机它不，显示不幸的MyApp已经停止然后出去？
我读了很多她的答案，所以我会为你提供logcat报告

顺便提一下，如果我的项目在一个Activity中有很多代码，那么它会产生影响
在我的项目中这样
package com.example.mrwan.superway;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class Main2Activity extends AppCompatActivity {
ImageView imageView2;
Button button2;
Button button3;
Button button4;
Button button5;
Button button6;
Intent i;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
imageView2 = (ImageView)findViewById(R.id.imageView2);
button2 = (Button)findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(Main2Activity.this,Main3Activity.class);
startActivity(i);
}
});
button3 = (Button)findViewById(R.id.button3);
button3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(Main2Activity.this,Main4Activity.class);
startActivity(i);
}
});
button4 = (Button)findViewById(R.id.button4);

}
});
button5 = (Button)findViewById(R.id.button5);
button5.setOnClickListener(new View.OnClickListener() {
@Override
