Google-API接続を実行し、アクティビティで情報を収集する機能。私は私の格納された情報（静的int変数に格納されている）を更新するたびに、私はIntentによってアクティビティを開始します。ユーザーを煩わせることなくアクティビティを開く
私は活動フォーム透明を作るために、スタイルを使用します。
<style name="Theme.Transparent" parent="android:Theme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
これは正常に動作しますが、私の問題は、すべての時間が活動「を示しアップ」ということで、彼らが入力しているときに、ユーザが中断取得したり、そんな感じ。アクティビティは、ブラウザURLバーのフォーカスを「盗み出し」、一例として入力します。
この現象を防止する方法はありますか？だから私は完全な沈黙活動が必要です。
