參考：Android集成
原理
點擊帶有referrer的鏈接（形如http://xxxx&referrer=test%3Dtest111）跳轉(zhuǎn)到Google Play后七问，Google Play會記錄(Capture)附帶的參數(shù)繁成，下載安裝后（經(jīng)測試疫稿，必須從Play商店點擊下載并安裝才可行）疾渣，首次打開APP時，Gooogle Play會將參數(shù)廣播(Deliver)給APP反浓。
流程
點擊帶有referrer的鏈接（形如http://xxxx&referrer=test%3Dtest111）>>跳轉(zhuǎn)到google play（Capture referrer for com.xxx.xxx ）>>下載完成>>打開app（Delivered referrer for com.xxx.xxx）
配置
新建一個繼承自BroadcastReceiver的類，用于接收referrer
public class InstallReferrerReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String referrer = intent.getStringExtra("referrer");
Log.e("zqj", "install referrer:" + referrer);
if(referrer != null && referrer.length() > 0){
Log.e("zqj", "install referrer:" + referrer);
return;
}
}
}
再在AndroidManifest中添加
<receiver
android:name="com.xxx.xxx.InstallReferrerReceiver"
android:exported="true"
android:permission="android.permission.INSTALL_PACKAGES" >
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
幾種情況：
1.沒有安裝app任内，通過http://xxxx&referrer=test%3Dtest111跳轉(zhuǎn)到Google Play，可以正常Capture referrer融柬，安裝app死嗦，打開app，可以正常deliver referrer: test=test111
2.沒有安裝app粒氧，通過http://xxxx&referrer=test%3Dtest111跳轉(zhuǎn)到Google Play越除，再通過http://xxxx&referrer=test%3Dtest222跳轉(zhuǎn)google play，安裝app外盯，打開app摘盆，deliver referrer: test=test222
3.沒有安裝app，通過http://xxxx&referrer=test%3Dtest111跳轉(zhuǎn)到Google Play饱苟，安裝app孩擂，再通過http://xxxx&referrer=test%3Dtest222跳轉(zhuǎn)google play，無法再次Capture referrer（Dropped referrer for com.peoplefun.wordcross because dropped_already_captured）箱熬，打開app类垦，可以正常deliver referrer: test=test111
4.已經(jīng)安裝app，通過http://xxxx&referrer=test%3Dtest111跳轉(zhuǎn)到Google Play城须，無法Capture referrer（Dropped referrer for com.peoplefun.wordcross because dropped_already_installed）
