Android-执行命令行脚本

方式一:

Runtime.getRuntime().exec(cmd);

方式二:

先是放入一个String数组,空格用,号代替,将cmd填入.涉及到静默安装的,这里需要root权限

        String[] args = {"pm", "install", "-t", "-r", apkPath, "--user", "0"};
        exeCmdArgs(args);

// 执行
 private static void exeCmdArgs(String[] args)
            throws Exception {
        ByteArrayOutputStream errorBuffer    = new ByteArrayOutputStream();
        ByteArrayOutputStream resultBuffer   = new ByteArrayOutputStream();
        ProcessBuilder        processBuilder = null;
        Process               process        = null;
        InputStream           errorInput     = null;
        InputStream           resultInput    = null;
        int                   byteOfRead     = 0;
        byte[]                buffer         = new byte[1024];
        try {
            processBuilder = new ProcessBuilder(args);
            process = processBuilder.start();

            errorInput = process.getErrorStream();
            while (-1 != (byteOfRead = errorInput.read(buffer))) {
                errorBuffer.write(buffer, 0, byteOfRead);
            }
            resultInput = process.getInputStream();
            while (-1 != (byteOfRead = resultInput.read(buffer))) {
                resultBuffer.write(buffer, 0, byteOfRead);
            }
            String error  = errorBuffer.toString("UTF-8");
            String result = resultBuffer.toString("UTF-8");
            System.out.println(error);
            System.out.println(result);
        } finally {
// 关闭
            close(errorInput, resultInput);
            destroy(process);
        }
    }
