android.view.InflateException: Binary XML file line #2: Error inflating class <unknown>

Question

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.

My activity Code :

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) {
}

}

My Xml Code:

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

<LinearLayout 
android:layout_width="fill_parent"

Images are of very small size around 5kb.

Answer 1

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.

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