You have another possibility if the device is rooted (has superuser rights).

You can invoke an external process that would use the su rights. But note that it's probably a bad design as Android OS should be the only one to kill processes.

try {
   Process rootProcess = Runtime.getRuntime().exec(new String[] { "su" });

   String command = "kill - 9 ";

   BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(rootProcess.getOutputStream()), 2048);
   try {
      bw.write(command);
      bw.newLine();
      bw.flush();
   } catch (IOException e) {
    // Handle error
   }
} catch (Exception e) {
   e.printStackTrace();
   // Device not rooted!            
}
