本文介绍了如何在Android中通过编程方式关闭当前运行的应用进程。首先获取应用的包名，然后使用Runtime执行ps命令找到对应进程ID，最后执行kill命令以结束该进程。

 private void killProcess(Context mAct) {
        // TODO Auto-generated method stub
        Log.i(TAG, "killProcess");
        String packageName =  mAct.getPackageName();
        String processId = "";
        try {
            Runtime r = Runtime.getRuntime();
            Process p = r.exec("ps");
            BufferedReader br = new BufferedReader(new InputStreamReader(p
                    .getInputStream()));
            String inline;
            while ((inline = br.readLine()) != null) {
                if (inline.contains(packageName)) {
                    Log.i(TAG, "" + inline);
                    break;
                }
            }
            br.close();
            StringTokenizer processInfoTokenizer = new StringTokenizer(inline);
            int count = 0;
            while (processInfoTokenizer.hasMoreTokens()) {
                count++;
                processId = processInfoTokenizer.nextToken();
                if (count == 2) {
                    break;
                }
            }
            Log.e(TAG, "kill process : " + processId);
            r.exec("kill -15 " + processId);
        } catch (IOException ex) {
            Log.e(TAG, "" + ex.getStackTrace());
        }
    }
