Handling different screen sizes (Android) -

since starting android development have have been using following drawable folder structure...

drawable-mdpi drawable-hdpi drawable-xhdpi drawable-xxhdpi

now problem this, im testing on 2 different devices

lenovo tab s8 - 1980*1200 - xxhdpi
nexus 5 - 1080*1920 - xxhdpi

the lenovo tabs physical screen-size twice of nexus, both pull images drawable-xxhdpi.

this means if build app nexus, when deployed on tab surrounded lots of blank unused space. if develop fit nicely on tab appears blown on nexus.

i have read here

(http://www.techotopia.com/index.php/handling_different_android_devices_and_displays)

to add drawable folder name

drawable-sw200dp
drawable-sw600dp
drawable-sw800dp

to handle different screen sizes crashes app on nexus. tab fine.

can explain why and/or workaround handle different sizes within xxhdpi category?

update:- xml layout appears causing proble (fragment_tutorial2.xml)...

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"                 android:paddingtop="20dip">     <textview         android:id="@+id/hint"         style="@style/tutorialtitle1"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="@string/tut_text2" />      <textview         android:id="@+id/hint2"         style="@style/tutorialtitle2"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_below="@id/hint"         android:text="@string/tut_text3"/>      <imageview         android:id="@+id/documentlist"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centervertical="true"         android:layout_centerhorizontal="true"         android:src="@drawable/documentlist" />  </relativelayout>

whats logcat throws

caused by: java.lang.outofmemoryerror: failed allocate 7607

http://developer.android.com/reference/java/lang/outofmemoryerror.html

too big android , goes out of memory.so,best resize images smaller size.

and add in imageview

android:adjustviewbounds="true" 

set true if want imageview adjust bounds preserve aspect ratio of drawable.

must boolean value, either "true" or "false".

you may set android:largeheap="true" in manifest application tag .
