我开发一个简单的应用程序。刚刚完成了主屏幕。如果方向变化超过2倍，则引发错误和应用是力闭合

I am developing a simple app. Just finished the home screen. If the orientation changes more than two times, it is throwing the error and application is force closing.

public class PasswordActivity extends Activity implements OnClickListener {
Button login;  
Button forgot;
Button register;  

private static final String PREFERENCES = "prefs";
private static final String PREFERENCES_NAME = "pref_name"; 
SharedPreferences settings;
private Cursor c;

@Override 
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main); 
    login=(Button)findViewById(R.id.login_login);
    login.setOnClickListener(this);
    register=(Button)findViewById(R.id.login_register);
    register.setOnClickListener(this);

}
public void onClick(View v) {
}

}

图像周围5KB非常小的。

Images are of very small size around 5kb.

推荐答案

在运行时，根据需要调整大小的Andr​​oid上的图像（基于屏幕大小和分辨率）。它采用位图的对内部做了调整大小。其中，很明显，是非常内存密集型（有点分配内存像疯了似的）。一个快速的方法来解决这样的问题就可以了，你们都绘制文件复制到可绘制-LDPI，MDPI，华电国际的文件夹。这样，Android将刚刚拿起文件从这些文件夹，而不是调整其大小。

At runtime, Android resize's images based on need (based on the screen size and resolution). It uses Bitmap's for doing the resizing internally. Which, obviously, is very memory intensive (kinda allocates memory like crazy). One quick way to fix such issues can be, that you copy all drawable files to drawable-ldpi, mdpi, hdpi folders. This way android will just pick up the files from these folders and not resize them.

它是一种随机的一种例外，一个真正的痛苦来解决。

Its a random kind exception, a real pain to fix.
