我有一个闪屏，显示 2 秒的图像。该图像是PNG图像。当我启动我的应用程序时，有时它会崩溃并显示以下错误消息。我的应用程序崩溃的确切行是 setContentView(R.layout.splash);

关键错误行：我可以看到在扩展布局时参考 java.lang.OutOfMemoryError 有一些错误

你能告诉我我需要在哪里更正我的代码吗？

XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout  
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent"  
android:layout_height="fill_parent" 
android:background="@drawable/splash">  

</RelativeLayout>

Java 代码：

 public class Splash extends Activity{
@Override
protected void onCreate(Bundle GoOnSudha) {
    // TODO Auto-generated method stub
    super.onCreate(GoOnSudha);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.splash);

    Thread thread = new Thread(){
        public void run(){
            try{
                sleep(2000);
            } catch (InterruptedException e){
                e.printStackTrace();
            }finally{
                Intent dragDropIntent = new Intent("android.intent.action.DRAGDROP");
                startActivity(dragDropIntent);
            }
        }
    };
    thread.start();
}

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

}

您的图像尺寸太大。您的应用程序超出了为您的应用程序分配的堆大小。因此，您将得到 OutofMemoryException。堆大小因设备而异。

缩小位图或使用占用更少内存的不同图像。

您需要有效地加载位图。检查在内存中加载缩小版本下的主题。

http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

还要在 onResume() 中将 drawable 加载到布局中，并在 onPause() 中将 drawable 与布局解除绑定。

2.5 mb 太大，无法显示几秒钟。如果它是位图文件，请尝试更改为更压缩的格式，因为它们很大并且占用大量内存，例如 Android 在这里所说的关于图像的内容

位图占用大量内存，尤其是对于照片等丰富的图像。例如，Galaxy Nexus 上的相机可拍摄高达 2592x1936 像素（5 兆像素）的照片。如果使用的位图配置是 ARGB_8888（Android 2.3 以后的默认配置），则将此图像加载到内存中大约需要 19MB 内存（2592*1936*4 字节），立即耗尽某些设备上的每个应用程序的限制。
