c 測(cè)試
代碼在google的官網(wǎng)中都有介紹，關(guān)鍵說下測(cè)試流程

1. 創(chuàng)建一個(gè)測(cè)試鏈接

https://play.google.com/store/apps/details?id=<com.xx.xx>  //yourAppId
&referrer=utm_source%3Dgoogle%26utm_medium%3Dcpc%26utm_term%3Dpodcast%252Bapps%26utm_content%3DdisplayAd1%26utm_campaign%3Dpodcast%252Bgeneralkeywords

2. 網(wǎng)頁打開測(cè)試鏈接，正確彈出你的app頁面
3. 點(diǎn)擊在google play中打開（記得提前卸載app）
4. 在google play下載頁面，選擇adb或者as安裝debug包

    adb install -r app-debug.apk 

5. 安裝成功后在google play頁面點(diǎn)擊啟動(dòng)

備注：如果google play的賬號(hào)之前測(cè)訂閱等問題被加入為測(cè)試賬號(hào)，要?jiǎng)?chuàng)建一個(gè)新的google賬號(hào)來測(cè)試，不然refererUrl還是拿不到
