\frameworks\base\services\core\java\com\android\server\pm\PackageManagerService.java

    private int[] performDexOptUpgrade(List<PackageParser.Package> pkgs, boolean showDialog,             final int compilationReason, boolean bootComplete) {

        int numberOfPackagesVisited = 0;         int numberOfPackagesOptimized = 0;         int numberOfPackagesSkipped = 0;         int numberOfPackagesFailed = 0;         final int numberOfPackagesToDexopt = pkgs.size();

添加一下3行  if (isFirstBoot() && Build.TYPE.equals("user")){            android.provider.Settings.Global.putInt(mContext.getContentResolver(), android.provider.Settings.Global.ADB_ENABLED, 0);  }
