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

Question

I am developing a simple android apllication and just completed the home screen. Now if the orientation of the screen changes more than two times, it is throwing the error and application is getting crashed abrubptly.

Here is my Java Class:

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) {   }  } 

And this is 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"     android:layout_height="wrap_content"     android:orientation="horizontal"     android:paddingTop="5dp"     android:paddingLeft="3dp"     android:paddingRight="3dp">        <TextView       android:layout_width="fill_parent"      android:layout_weight="0.75"      android:layout_height="wrap_content"      android:text="@string/login_user_name"      android:textStyle="bold"/>      <EditText       android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:layout_weight="0.25"      android:id="@+id/login_user_name"      android:inputType="text"/>   </LinearLayout>    <LinearLayout       android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:orientation="horizontal"      android:paddingLeft="3dp"      android:paddingRight="3dp">         <TextView        android:layout_width="fill_parent"       android:layout_weight="0.75"       android:layout_height="wrap_content"       android:text="@string/login_password"       android:textStyle="bold"/>       <EditText        android:layout_width="fill_parent"       android:layout_height="wrap_content"       android:layout_weight="0.25"       android:inputType="textPassword"       android:id="@+id/login_password"/>   </LinearLayout>    <LinearLayout       android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:orientation="horizontal"      android:paddingLeft="3dp"      android:paddingRight="3dp">         <Button        style="@style/left_button"       android:text="@string/login_submit"       android:id="@+id/login_login"/>       <Button         style="@style/right_button"        android:id="@+id/login_register"        android:text="@string/register"/>    </LinearLayout> </LinearLayout>

Images used 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.

Answer 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
