I've in drawable directory an image file with the 960x1440 size. When the app start, the image is not loaded as background and in the logcat I see:
Bitmap too large to be uploaded into a texture (2880x4320, max=4096x4096)
Why it says 2880x4320 if the image is 960x1440 ?
The bitmap is loaded via xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/launcher_bg"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin">
an image in the /drawable/
folder without any specification is considered to be the "default", that is for 1dp = 1px that is mpdi
, then because the device you're actually running is xxhdpi
that image get's scaled up during runtime.
The original image might be 960x1440, but the conversion from mdpi
to xxhdpi
is 3 times the size, so your 960x1440 becomes (3*960)x(3*1440) = 2880x4320, which is too large of a texture to apply to the hardware accelerated views.
so to fix that is actually pretty simple, you have two choices:
/drawable-nodpi/
that's simple, reduces the .apk size, but lower end devices might struggle to load such a big image.mdpi
, hdpi
, xhdpi
, xxhdpi
to avoid runtime over-scaling and to have smaller images on older devices.If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
