CSipSimple throwing exception on android lollipop.

JNI DETECTED ERROR IN APPLICATION,input is not valid Modified UTF-8: illegal start byte 0x8e

while doing voip call, here i am sending message to ISipService in interval just to check call is going on or disconnected. and i am getting this exception on pjStr.getPtr() which is in pjSipService.java class. here i am pasting my error log.

any idea? or any alternative to get notify if call had been disconnected by other party? or wifi get disconnected on other device and for that i will get notification that call is disconnected.

This error will throw for lollipop and higher version, because they are using ART, and some symbols are unable to detect by it.

  • you are right! The same code that is working pretty fine on Android version previous to Lollipop. what can be the possible solution for the same! Please help ! – New Coder Feb 19 '16 at 12:59

Maybe there is something in this post that will help.

Do not use the JNI call to NewStringUTF unless you control the input 100%

In short, see the above link. Try avoiding the use of NewStringUTF and send a byte array of your input into java and have it make the jstring.

I won't pretend to understand CSipSimple's implementation, but I would not be surprised if this is indeed the source of your problem. I hope that helps. This problem plagues us since Android 5 came out and has slowly become a large problem with using the JNI with user created strings using their soft keyboards.
