android -- 小功能 apk 静默安装

废话不多说，直接上代码  ：

 /**
      * 软件静默安装
      * @param apkAbsolutePath apk文件所在路径
      * @return 安装结果:获取到的result值<br>
      *
      * 如果安装成功的话是“
      * pkg: /data/local/tmp/Calculator.apk  /nSuccess”，<br>
      * 如果是失败的话，则没有结尾的“Success”。
      */
     public String silentInstall(String apkAbsolutePath) {
         String[] args = { "pm", "install", "-r", apkAbsolutePath };
         String result = "";
         ProcessBuilder processBuilder = new ProcessBuilder(args);
         Process process = null;
         InputStream errIs = null;
         InputStream inIs = null;

         try {
             ByteArrayOutputStream baos = new ByteArrayOutputStream();
             int read = -1;
             process = processBuilder.start();
             errIs = process.getErrorStream();

             while ((read = errIs.read()) != -1) {
                 baos.write(read);
             }

             baos.write("/n".getBytes());
             inIs = process.getInputStream();

             while ((read = inIs.read()) != -1) {
                 baos.write(read);
             }

             byte[] data = baos.toByteArray();
             result = new String(data);
         } catch (IOException e) {
             e.printStackTrace();
         } catch (Exception e) {
             e.printStackTrace();
         } finally {

                 e.printStackTrace();
             }
             if (process != null) {
                 process.destroy();
             }
         }
         return result;
     }

 

别急，没完，记得加权限呢：
