Play Install Referrer 库

错误1：

使用过程中会发现无论设备是否有安装GoogleService, 都会偶发性产生如下崩溃：

Fatal Exception: java.lang.RuntimeException: Unable to resume activity
 {**}:java.lang.SecurityException: Not allowed to bind to service Intent 
  { act=com.google.android.finsky.BIND_GET_INSTALL_REFERRER_SERVICE cmp=com.android.vending/com.google.android.finsky.externalreferrer.GetInstallReferrerService }
       at android.app.ActivityThread.performResumeActivity(ActivityThread.java:3216)
       at android.app.ActivityThread.handleResumeActivity(ActivityThread.java:3247)
       at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1458)
       at android.os.Handler.dispatchMessage(Handler.java:102)
       at android.os.Looper.loop(Looper.java:148)

       at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:737)

可通过下面try....catch方案进行处理：

try {
            mReferrerClient.startConnection(installReferrerStateListener);
        } catch (RuntimeException e) {
            CrashLoggingUtils.logException(e, T.UTILS);
            AppLog.e(T.UTILS, "installation referrer start connection failed!", e);
            AnalyticsTracker.track(Stat.INSTALLATION_REFERRER_FAILED);

            // just bail if we were not able to connect to the installation referrer service
            stopService();
        }
