Android 兑现静默安装

Android 实现静默安装

签名流程：

前提： 拿到系统的签名文件platform.x509.pem 和 platform.pk8，同时找到signapk.jar工具包(android源码中有对应类，可以拿到源码后

手动生成jar文件)

具体步骤如下：
 1. 将下载完毕的apk文件重新签名，文件签名和系统签名保存一致。
            java -jar signapk.jar platform.x509.pem platform.pk8 待签名.apk 已签名.apk
 2. 执行"pm", "install", "-r", apkInstallPath。开始安装。
  附代码：

/**Android静默安装实现*/ public static void silenceInstall(String apkInstallPath) {  String[] args = { "pm", "install", "-r", apkInstallPath + "mobile_client_2.1.apk" };  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');      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 {   try {    if (errIs != null) errIs.close();    if (inIs != null) inIs.close();   } catch (IOException e) {    e.printStackTrace();   }      if(process != null) process.destroy();  }  Log.d("mylog", "执行静默安装后的返回值：" + result); }

================================================================================

在代码中实现签名：

/** * apk文件签名实现 * @param apkPrePath签名前的文件路径 * @param apkCurPath生成签名后的文件路径 */public void signToApk(String apkPrePath, String apkCurPath) {Toast.makeText(MainActivity.this, apkPrePath, Toast.LENGTH_SHORT).show();String[] args = { "java", "-jar", apkPrePath + "signapk.jar", apkPrePath + "platform.x509.pem.pem", apkPrePath + "platform.pk8.pk8", apkPrePath + "mobile_360_client_2.1.apk", apkPrePath + "mobile_360_client_2.1_cur.apk"};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');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 {try {if (errIs != null) errIs.close();if (inIs != null) inIs.close();} catch (IOException e) {e.printStackTrace();}if(process != null) process.destroy();}}

如果是在命令行中生成签名， 则直接在cmd窗口中输入java -jar signapk.jar platform.x509.pem platform.pk8 待签名.apk 已签名.apk即可。
