在应用程序中添加shell 执行命令脚本

具体code ，请参考下面的函数

public boolean execCommand(String cmd){
    Process  mProcess = null;
    try {
        mProcess = Runtime.getRuntime().exec(cmd);
        mProcess.waitFor();
    } catch(Exception e) {
        return false;
    } finally {
        try {
            mProcess.destroy();
        } catch(Exception e){

        }
    }
    return true;
}

public void execShell(String cmd ) {

    Process  mProcess = null;
    try {
        mProcess = Runtime.getRuntime().exec("su");
        OutputStream outputStream = mProcess.getOutputStream();
        DataOutputStream dataOutputStream = new DataOutputStream(outputStream);
        dataOutputStream.writeBytes(cmd);
        dataOutputStream.flush();
        dataOutputStream.close();

    } catch (Exception e){
        e.printStackTrace();
    }

}
