com.google.android.permission.gts.DefaultPermissionGrantPolicyTest#estDefaultest

有时候我们内置了第三方应用，在DefaultPermissionGrantPolicy.Java赋给应用默认权限，但是会影响GTS测试，下面的方法可以规避此问题
    @Override
    public int checkPermission(String permName, String pkgName) {
        try {
            String taker = mContext.getPackageName();
            if ("com.google.android.permission.gts".equals(taker)) {
                String[] whiteLists = new String[] { "包名"};
                for (String pkg : whiteLists) {
                    if (pkg.equals(pkgName)) {
                        return PERMISSION_DENIED;
                    }
                }
            }
            return mPM.checkPermission(permName, pkgName, mContext.getUserId());
        } catch (RemoteException e) {
            throw new RuntimeException("Package manager has died", e);
        }
    }
