在自定義的application基類中的onCreate()方法中使用
AppStateTracker.track(this, new AppStateTracker.AppStateChangeListener() {
@Override
public void appTurnIntoForeground() {
// 處理app到前臺的邏輯
touchEventRecord = new TouchEventRecord("appresume",System.currentTimeMillis(),0,0);
}
@Override
public void appTurnIntoBackGround() {
// app處理到到後臺的邏輯
}
});
