java.lang.IllegalArgumentException: Disk Cache Location is not write-able

[bostone]

I have this piece of code to init image cache

final BitmapLruCache.Builder builder = new BitmapLruCache.Builder(context.getApplicationContext());
        builder.setMemoryCacheEnabled(true).setMemoryCacheMaxSizeUsingHeapSize();
        builder.setDiskCacheEnabled(true).setDiskCacheLocation(cacheLocation)
                .setRecyclePolicy(RecyclePolicy.DISABLED);
        this.imageCache = builder.build();

Sometimes it fails at the last line which I think is wrong. It should just gracefully disable SD caching if the error is caught

Here's stack trace
