錯誤，同時登錄到谷歌玩遊戲服務：looper.prepare（）不能被稱爲

Question

我收到此錯誤從我的發揮開發者控制檯： -

它看起來像它崩潰，當用戶無法登錄谷歌播放服務，但我無法弄清楚這個問題的解決方案。

Answer 1

你正試圖從後臺線程顯示AlertDialog。爲了顯示你的對話框添加Looper.prepare（）或顯示與mainUiThread對話框。

Answer 2

您是否嘗試過：的

runOnUiThread(new Runnable() { @Override public void run() { gameHelper.beginUserInitiatedSignIn(); } });

，而不是僅僅

gameHelper.beginUserInitiatedSignIn();

？
