I am running the app on Galaxy Note, which is hdpi. And I got all the drawables (drawable-hdpi, drawable-mdpi etc.) correct. But the page (activity) is weirdly zoomed in like this:

You can notice that the cursor icon, top header and the background tiles are larger than normal.
It is supposed to be like this:

The layout file:
<?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="fill_parent"
android:orientation="vertical"
android:background="@drawable/bg_app"
>
<EditText android:id="@+id/content"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:inputType="textMultiLine|textCapSentences"
android:textColor="#000"
android:textSize="18sp"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:gravity="top|left"
android:padding="10dp"
android:layout_margin="10dp"
android:lineSpacingMultiplier="1.1"
android:minLines="3"
/>
</LinearLayout>
Problem solved by using
in AndroidManifest.xml
