Google市场推广统计

Google Play作为Android最大的应用市场，也存在这推广等常用的行为，那么如何统计呢，Google Analytics SDK或者其他的SDK都提供了方法，实际上是可以不需要任何sdk，完全可以自己实现的。
原理是这样的：当来自Play Store上的应用被安装之后，Play Store会发送一个指定的广播给被安装的包，广播的action为com.android.vending.INSTALL_REFERRER。内容数据类似于 utm_source%3Dgoooooogggggggggggggle%26utm_medium%3Dcpc%26utm_term%3Dandroid%252Bbrowser%26utm_content%3Dmaxthon%2520browser%2520for%2520android%26utm_campaign%3DYou%2520never%2520know%2520fast. 我们只需要接收这个广播处理即可。

首先在manifest中增加receiver来接收

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

这里的AnalyticsReceiver是专门接收推广广播的。
代码很简单

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();
 
	@Override
	public void onReceive(Context context, Intent intent) {
		Log.i(LOGTAG + "_demo", "analyticsReceiver = " + intent + "data in String = " + intent.getStringExtra("referrer"));
	}
 
}

这样基本上就完成了，关于简单测试，可以使用下列代码：

        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);
