Google市場推廣統計

Google Play作為Android最大的應用市場，也存在這推廣等常用的行為，那麼如何統計呢，Google Analytics SDK或者其他的SDK都提供了方法，實際上是可以不需要任何sdk，完全可以自己實現的。
原理是這樣的：當來自Play Store上的應用被安裝之後，Play Store會發送一個指定的廣播給被安裝的包，廣播的action為com.android.vending.INSTALL_REFERRER。內容資料類似於 utm_source%3Dgoooooogggggggggggggle%26utm_medium%3Dcpc%26utm_term%3Dandroid%252Bbrowser%26utm_content%3Dmaxthon%2520browser%2520for%2520android%26utm_campaign%3DYou%2520never%2520know%2520fast.
我們只需要接收這個廣播處理即可。

首先在manifest中增加receiver來接收

 <receiver android:name=".AnalyticsReceiver" android:exported="true" >  <intent-filter>    <action android:name="com.android.vending.INSTALL_REFERRER" />  </intent-filter>   </receiver>

這裡的AnalyticsReceiver是專門接收推廣廣播的。
代碼很簡單

package com.example.installreceiverdemo; import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log; public class AnalyticsReceiver extends BroadcastReceiver { private static final String LOGTAG = AnalyticsReceiver.class.getSimpleName(); @Overridepublic void onReceive(Context context, Intent intent) {Log.i(LOGTAG + "_demo", "analyticsReceiver = " + intent + "data in String = " + intent.getStringExtra("referrer"));} }

這樣基本上就完成了，關於簡單測試，可以使用下列代碼：

        Intent it = new Intent("com.android.vending.INSTALL_REFERRER");        it.setPackage("com.example.installreceiverdemo");        it.putExtra("referrer", "utm_source%3Dgoooooogggggggggggggle%26utm_medium%3Dcpc%26utm_term%3Dandroid%252Bbrowser%26utm_content%3Dmaxthon%2520browser%2520for%2520android%26utm_campaign%3DYou%2520never%2520know%2520fast.");        sendBroadcast(it);
