安卓APP获取ROOT权限

我们在app的开发过程中会遇到些需要系统支持的权限，这里有些是需要向系统申请的。写入这些申请的前提是该app安装的设备已经被破解了。

   /**
     * 应用程序运行命令获取 Root权限，设备必须已破解(获得ROOT权限)
     *
     * @param command 命令：String apkRoot="chmod 777 "+getPackageCodePath(); RootCommand(apkRoot);
     * @return 应用程序是/否获取Root权限
     */
    public boolean RootCommand(String command) {
        Process process = null;
        DataOutputStream os = null;
        DataInputStream is = null;
        try {
            process = Runtime.getRuntime().exec("su");
            os = new DataOutputStream(process.getOutputStream());
            os.writeBytes(command + "\n");
            os.writeBytes("exit\n");
            os.flush();
            int aa = process.waitFor();
            Logs.w("waitFor():"+aa);
            is = new DataInputStream(process.getInputStream());
            byte[] buffer = new byte[is.available()];
            Logs.d("大小"+buffer.length);
            is.read(buffer);
            String out = new String(buffer);
            Logs.e("返回:"+out);
        } catch (Exception e) {
            e.printStackTrace();
            Logs.e(tag + "205:\n" + e);
            return false;
        } finally {
            try {
                if (os != null) {
                    os.close();
                }
                if (is != null) {
                    is.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
                Logs.e(tag + "217:\n" + e);
            }
            process.destroy();
        }
        Logs.d(tag + "222 SUCCESS");
        return true;
    }

调用方法

String apkRoot = "chmod 777 " + getPackageCodePath();//getPackageCodePath()来获得当前应用程序对应的 apk 文件的路径

boolean b = RootCommand(apkRoot);
Logs.v("获取Root权限:"+b);
