嗨专家/专家黑客，
我正在尝试在 android 上实现 Google Play 应用程序静默安装功能（类似于 appbrain 快速网络安装程序）。
到目前为止，我能够实现以下目标：
找出一种检索 Google Play Auth Token 的方法（从而授予我的应用程序与电话上的 Google Play 应用程序通信的权限）。我在下面列出了我用于此的代码：
Log.i(TAG,"Getting the Google Play Auth Token Using Account Manager : START"); AccountManager accountManager = AccountManager.get(getApplicationContext()); Account[] accArr = accountManager.getAccountsByType("com.google"); for (Account acc : accArr) { Log.i(TAG, "For Account Name : " + acc.name + " - "+ "Account Type : " + acc.type); accountManager.getAuthToken(acc, "googleplay", null, this,new AccountManagerCallback<Bundle>() { public void run( AccountManagerFuture<Bundle> paramAccountManagerFuture) { try { Bundle localBundle = (Bundle) paramAccountManagerFuture.getResult(); String authToken = localBundle.get("authtoken") + ""; Log.i(TAG, "Got AuthToken : " + authToken); } catch (Exception ex) { StackTraceElement[] starray = ex.getStackTrace(); StringBuffer bf = new StringBuffer(); bf.append("Error : " + ex.getMessage()).append("\n"); for (StackTraceElement ste : starray) { bf.append(ste.toString()).append("\n"); } Log.e(TAG, bf.toString()); } } }, null); } Log.i(TAG,"Getting the Google Play Auth Token Using Account Manager : END")了解如何检索手机的 Android-Id（我认为应该在将 appInstall 请求发送到 GPlay 服务器或 Android 手机上的 Gplay/vending 应用程序时使用此 ID）
Log.i(TAG, "Getting the Android ID Of the Phone : START"); Uri localUri = Uri.parse("content://com.google.android.gsf.gservices"); ContentResolver localContentResolver = getContentResolver(); String[] arrayOfString = new String[1]; arrayOfString[0] = "android_id"; Cursor localCursor = localContentResolver.query(localUri, null,null, arrayOfString, null); Log.i(TAG, "Column Count : " + localCursor.getColumnCount()); if ((localCursor != null) && (localCursor.moveToFirst())) { String androidId = Long.toHexString(Long.parseLong(localCursor.getString(1))); Log.i(TAG, "Received Android ID : " + androidId); Log.i(TAG,"Other Value in Column : " + localCursor.getString(0)); } Log.i(TAG,"Getting the Android ID of the Phone : END");找出要发送到 Google Play 服务器或手机上的 Gplay/vending 应用程序的协议缓冲区请求，以启动静默应用程序下载和安装过程。
message InstallRequest { optional string appId = 1; } message RequestContext { required string authSubToken = 1; required bool isSecure = 2; required int32 version = 3; required string androidId = 4; optional string deviceAndSdkVersion = 5; optional string userLanguage = 6; optional string userCountry = 7; optional string operatorAlpha = 8; optional string simOperatorAlpha = 9; optional string operatorNumeric = 10; optional string simOperatorNumeric = 11; } message Request { optional RequestContext context = 1; repeated group RequestGroup = 2 { optional InstallRequest installRequest = 10; } }
4.我什至使用了 protobuf 编译器并生成了用于处理上述协议缓冲区请求的 java 类，并用一些示例数据填充了上述协议缓冲区字段。请参阅下面的代码：
public void buildAndSendSilentInstallProtoBuffMessage(String gplayAuthToken, String deviceAndroidId){
try{
/*
* The Root Request Object Assumed to be Holding the Silent Install Request
*/
Request.Builder request = Request.newBuilder();
//Populating the ReequestContext Object
RequestContext.Builder context = RequestContext.newBuilder();
context.setAndroidId(deviceAndroidId);
context.setAuthSubToken(gplayAuthToken);
context.setIsSecure(true);
context.setVersion(1002);
context.setDeviceAndSdkVersion("dream:4");
context.setUserLanguage("en");
context.setUserCountry("us");
context.setOperatorAlpha("Android");
context.setOperatorNumeric("310260");
context.setSimOperatorNumeric("310260");
//Building the Install Request
InstallRequest.Builder installRequest = InstallRequest.newBuilder();
installRequest.setAppId("-2564446724934482383");
//Setting the Install Request to the Request Group
RequestGroup.Builder requestGroup = RequestGroup.newBuilder();
requestGroup.setInstallRequest(installRequest);
//Setting the Request Context to the Main Request Object
request.setContext(context);
//Setting the Request Group to the Request Object
request.addRequestGroup(requestGroup);
GPlay Token 和 Android Id 的示例数据如下：
- Android_ID：
3a0f901831a0f402
- 谷歌播放验证令牌：

- 在 Gplay 应用程序静默安装期间，我还使用我的有根 Galaxy nexus 手机进行了一些嗅探，发现只有两个 HTTP GET 请求。
我尝试复制使用 Shark for root 捕获的这两个 Http GET 请求（使用我的 root android Galaxy nexus 手机），第一个请求只是下载市场文件本身（我能够将其保存到手机的 SD 卡中。但后来它必须像任何未知来源的应用程序一样安装），而第二个请求什么也不返回。
捕获的两个 get 请求如下所示：
得到一个请求：
21 0.827240 192.168.135.102 173.194.36.4 HTTP 535 GET /market/download/Download? packageName=com.gau.go.launcherex.theme.appwidget.gopowermaster.futureworld&versionCode=1&token=AOTCm0QRnH3rmypWtCGoAL_SU1BSt311wpyz-_LZTodkUSAlc- f5SrdMiz5WDRDUKMMm6S3plBI9Jbh1tukT1jyCYXLgP4QhVvZvn5JLtZQ&downloadId=-165214892049282883 HTTP/1.1 Which has the following http headers : Cookie: MarketDA=17214805622679635526\r\n Host: android.clients.google.com\r\n Connection: Keep-Alive\r\n User-Agent: AndroidDownloadManager/4.1.1 (Linux; U; Android 4.1.1; Galaxy Nexus Build/JRO03C)\r\n获取请求二：

我已经研究了大约两个星期了，但我仍然找不到以下内容：
AppBrain fast Web Installer 是否使用协议缓冲区来调用手机或 Gplay 服务器上的 Gplay（自动售货应用程序）？如果是这样，上述协议缓冲区请求格式是否正确？？
如果上述协议缓冲区请求格式正确，那么我应该在电话或 Gplay 服务器中的何处发送协议缓冲区请求以调用静默应用程序下载和安装程序？
我也有一个围绕这个任务的 C2DM（现在是 GCM）服务器和客户端设置。谁能指出我正确的方向或给我任何解决这个问题的线索？任何帮助深表感谢 。
