[io] OutOfMemory exception in IOUtils.toByteArray
Hello,
I am using Commons.io.IOUtils library in my android application. I have received this error:
Fatal Exception: java.lang.OutOfMemoryError
at org.apache.commons.io.output.ByteArrayOutputStream.needNewBuffer
at org.apache.commons.io.IOUtils.toByteArray
at com.alhuda.qih.DownloadCompleteReceiver.onReceive
I have tried to catch with IOException but no luck. Is there any way to handle this exception, so I can show the user-friendly message instead of getting the application crashed?
Regards,
Zishan J.

Do you need the entire thing in memory? What are you trying to do? You
typically can't do much with Errors (which don't extend Exception, but
Throwable) as it means a catastrophic event for the JVM.

You can try and catch the OutOfMemoryError:
try {
doSomething();
} catch (OutOfMemoryError e) {
Boolean a = true; // Stop the debugger here
}
To handle this really though you want a reserve bit of memory to release and have a way to swap some of your data used by your application from the fast access memory to another store (assuming you need it later, if not just delete all references to it and leave it to garbage collection).

Try to use Exception ( this is for all errors )

I am not familiar with the Android environment, but another way to solve this issue might be to allow the application to use more memory perhaps by specifying a -Xmx option in the java run command.

Read through [1] and [2]
"Errors are abnormal conditions that should never occur" and there is
usually no recovering from it. You can catch it with "OutOfMemoryError"
itself, with "Error" or with "Throwable" [3], if you need and try to
display a message.
Best approach is to check what consumes memory and try to solve the
problem. Android Device Monitor will come in handy with checking relevant
details [4].
