问题
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"

Images are of very small size around 5kb.
回答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.
回答2:
please follow background image size
for Supported device
LDPI:
Portrait: 200x320px
Landscape: 320x200px
MDPI:
Portrait: 320x480px
Landscape: 480x320px
HDPI:
Portrait: 480x800px
Landscape: 800x480px
XHDPI:
Portrait: 720px1280px
Landscape: 1280x720px

As the others clarified, part of a problem was an issue related to the background image I'd set for my layout. However, getting that solved, I persistently encountered the error:
Unfortunately the application has stopped
With trial and error, I found the problem was caused by the <view> elements which after deleting them, I could eventually run the application.
