android如何实现静默安装哦

android如何实现静默安装哦

原理
静默安装、卸载的原理就是利用pm install命令来安装apk，pm uninstall 来卸载apk.
智能安装是利用android系统提供的无障碍服务AccessibilityService，来模拟用户点击，从而自动安装.
//静默安装
    private void installSlient() {
        String cmd = "pm install -r /mnt/sdcard/test.apk";
        Process process = null;
        DataOutputStream os = null;
        BufferedReader successResult = null;
        BufferedReader errorResult = null;
        StringBuilder successMsg = null;
        StringBuilder errorMsg = null;
        try {
            //静默安装需要root权限
            process = Runtime.getRuntime().exec("su");
            os = new DataOutputStream(process.getOutputStream());
            os.write(cmd.getBytes());
            os.writeBytes("
");
            os.writeBytes("exit
");
            os.flush();
            //执行命令
            process.waitFor();
            //获取返回结果
            successMsg = new StringBuilder();
            errorMsg = new StringBuilder();
            successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));
            errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));
            String s;
            while ((s = successResult.readLine()) != null) {
                successMsg.append(s);
            }
            while ((s = errorResult.readLine()) != null) {
                errorMsg.append(s);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (os != null) {
                    os.close();
                }
                if (process != null) {
                    process.destroy();
                }
                if (successResult != null) {
                    successResult.close();
                }
                if (errorResult != null) {
                    errorResult.close();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        //显示结果
        tvTest.setText("成功消息：" + successMsg.toString() + "
" + "错误消息: " + errorMsg.toString());
    }

静默安装是指应用商店那些应用自动安装吗

要么root，要么给应用添加辅助功能
