问题
I'm using the metada-exttractor in android ver.: 2.7.0.
And this lib sometimes throw this exception:`
STACK_TRACE=java.lang.RuntimeException: An error occured while executing doInBackground()
at android.os.AsyncTask$3.done(AsyncTask.java:300)

This throws only sometimes in same cases, I CANNOT catch or solve this problem because is in the library....
回答1:
It could be a corrupted metadata in your image. Have you tried other images?
This forum post seems to suggest that was the cause for some other users.
