大致需求是這樣：app中assert檔案下有一些配置檔案，指令碼檔案，要求在開機啟動後，將assert下的檔案拷貝到手機中，並執行shell指令碼檔案。

監聽開機廣播的不多說。
提供如下方法：

    /***
     * 將檔案拷貝到某個目錄下，要賦予這個目錄相應的許可權
     * @param pkgCodePath
     * @return
     */
    private boolean upgradeRootPermission(String pkgCodePath) {
        Process process = null;
        DataOutputStream os = null
 
;
        try {
            String cmd = "chmod 777 " + pkgCodePath;
            process = Runtime.getRuntime().exec("su"); // 切換到root帳號
            os = new DataOutputStream(process.getOutputStream());
            os.writeBytes(cmd + "\n");
            os.writeBytes("exit\n");
            os.flush();
            process.waitFor();
        } catch
 
 (Exception e) {
            return false;
        } finally {
            try {
                if (os != null) {
                    os.close();
                }
                process.destroy();
            } catch (Exception e) {
            }
        }
        return true;
    }

    /**
     * 拷貝檔案
     * @param

     * @param oldPath
     * @param newPath
     */
    private void copyData(Context context, String oldPath, String newPath) {
        InputStream in = null;
        FileOutputStream out = null;
        File file = new File(newPath);
        if (!file.exists()) {
            try {
                Log.d(TAG, "inStream: -------->>>>>>.");
                in = context.getAssets().open(oldPath); // 從assets目錄下複製
                Log.d(TAG, "inStream: .");
                upgradeRootPermission("/data");//拷貝到data目錄下，data目錄必須給出相應的許可權
                out = new FileOutputStream(file);
                int length = -1;
                byte[] buf = new byte[1024];
                while ((length = in.read(buf)) != -1) {
                    out.write(buf, 0, length);
                }
                out.flush();

            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if (in != null) {
                    try {
                        in.close();
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }
                }
                if (out != null) {
                    try {
                        out.close();
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }
                }
            }
        }
    }

同時給大家提供一個呼叫shell指令碼的工具類

ShellUtils.CommandResult result = ShellUtils.execCommand(your command,是否root);
