title: How to send sigint signal to Android NDK processes?
body: <p>I am running a native method in a java AsyncTask that waits for a ctrl+c or SIGINT signal to finish.</p>
  
  <p>This stop signal should be given from java, but <code>system("kill -INT -1");</code> in a second native method doesnt seem to have an effect when called through the jni. How can I send a sigint to the first NDK call?</p>
