Android Preload Crash

See original GitHub issue

Hi,

Some android users are experiencing crashes when trying to preload android. here’s the stacktrace from Fabric

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.app.Activity.runOnUiThread(java.lang.Runnable)' on a null object reference
       at com.dylanvann.fastimage.FastImageViewModule.preload(FastImageViewModule.java:36)

       at java.lang.Thread.run(Thread.java:761)

This is not happening for all users or all devices. And doesn’t seems to be the memory issue

Any idea how to go about fixing this?

@rochapablo I am also getting this on some devices. Specifically saw this coming from Nexus 5X. Any help?

Checking for null activity has been merged, thank you @Kouznetsov

For future reference this seems to happen when a preload is called from JS, and then the native activity becomes null. In this case we just do not perform the preloading.
