Question

每次我尝试运行模拟器时都会崩溃。这是我收到的logCat：

这是我的Java代码：

package com.example.secondapp;

import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;

public class Splash extends Activity {

MediaPlayer ourSong;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);
    ourSong = MediaPlayer.create(Splash.this, R.raw.happyman);
    ourSong.start();
    Thread timer = new Thread(){
        public void run(){
            try{
                sleep(1000);
            } catch (InterruptedException e){
                e.printStackTrace();
            }finally{
                Intent startMain = new Intent("com.example.secondapp.MainActivity");
                startActivity(startMain);
            }
        }
    };
    timer.start();
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    ourSong.release();
    finish();
}

}

我已经尝试了所有修复它的东西，但我似乎无法找到问题。有人可以帮我吗？

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" 
android:background="@drawable/background1"

你已经在评论中找到了解决方案，但是这里是你如何调试这样的堆栈跟踪：

10-31 09:09:59.453: E/AndroidRuntime(1840): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.secondapp/com.example.secondapp.MainActivity}: android.view.InflateException: Binary XML file line #1: Error inflating class <unknown>

XML布局文件行＃1中的问题。

再向下：

10-31 09:09:59.453: E/AndroidRuntime(1840):     at android.app.Activity.setContentView(Activity.java:1895)
10-31 09:09:59.453: E/AndroidRuntime(1840):     at com.example.secondapp.MainActivity.onCreate(MainActivity.java:19)

查看代码：

     setContentView(R.layout.splash);

所以它是layout/splash.xml文件。

此外：

10-31 09:09:59.453: E/AndroidRuntime(1840): Caused by: java.lang.OutOfMemoryError
10-31 09:09:59.453: E/AndroidRuntime(1840):     at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)

解码资产（可绘制资源）位图时，内存不足。

在splash.xml第一行元素中，只有一个对可绘制资源的引用：

android:background="@drawable/background1"

所以解决方法是检查background1 drawable并将其缩小，以便解码它不会占用太多内存。
