Android O: Dragshadowbuilder Throws Illegalstateexception: Software Rendering Doesn't Support Hardware Bitmaps

My Android app allows users to drag and drop images in an activity. It used to work fine until Android O and hardware image acceleration arrived. The code throws the following exce

Solution 1:

This Glide issue on the Glide web site explains what's going on: https://github.com/bumptech/glide/issues/2309

The solution is to disable hardware acceleration in Glide: http://bumptech.github.io/glide/javadocs/431/com/bumptech/glide/request/RequestOptions.html#disallowHardwareConfig--

Disables the use of Bitmap.Config.HARDWARE in Downsampler to avoid errors caused by [...] drawing to Canvass backed by Bitmaps

The code below shows how to disable hardware acceleration for the specific image.

            GlideApp.with(context)
                .applyDefaultRequestOptions(new RequestOptions().disallowHardwareConfig())
                .load(imageUrl)
                .into(imageView);

Solution 2:

Workaround for ANDROID O causes an error"IllegalStateException: Software rendering doesn't support hardware bitmaps".

Recode your public class GlideConfiguration extends AppGlideModule as below:

RequestOptionsoptions=newRequestOptions();
    booleanisAndroidO= (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O);
    DecodeFormatformat= isAndroidO ? DecodeFormat.PREFER_ARGB_8888 : DecodeFormat.PREFER_RGB_565;
    options.format(format);
    if (isAndroidO) options.disallowHardwareConfig();

    builder.setDiskCache(newInternalCacheDiskCacheFactory(context, diskCacheSizeBytes));
    builder.setDefaultRequestOptions(options);

Solution 3:

Disclaimer:- I didn't use glide in this activity still I was getting "IllegalStateException: Software rendering doesn't support hardware bitmaps"

I solved this error by creating a new activity and copy the code block while also checking does my app run after adding code.

finally, my app is running without any error and I didn't get why this error was thrown.
