問題描述

項目中無法執行c程序，猜測是exec()函數的問題

String cmd= exe_path + ' ' +video + ' ' +host + ':' + port; Process process = runtime.exec(cmd);

問題解答

String[] cmd = new String[]{exe_path, video, host + ':' + port}回答2：

String[] cmd = {'/data/data/app_name/exename', '3' 'ip:port'};java.lang.ProcessBuilder builder = new java.lang.ProcessBuilder(cmd);java.lang.Process process = builder.start();int exitcode = process.waitFor();
