我已经发布了一个新版本的扩展。它已被标记为“待审核”，因为清单有一些权限更改。现在我不想发布新版本的扩展。有什么办法可以阻止吗？我只是想让用户继续使用已经发布的扩展版本

（不知道还能去哪里问）

我正在使用以下代码在onPause中释放相机.但是线路mCamera.release()平均需要30秒才能在Nexus 10设备中释放相机.我在mCamera.release()之前和之后添加了日志记录,发现打印这些日志的时间差是30秒.

private void releaseCamera() {
    if (mCamera != null) {
        previewing = false;
        mCamera.setPreviewCallback(null);
        if(mPreview != null)
        mPreview.getHolder().removeCallback(mPreview);
        Log.e("QR","Starting to call mCamera.release()");
        mCamera.release();
        Log.e("QR","Released Camera");
        mCamera = null;
    }
}

我在调用releaseCamera()之前调用了mCamera.stopPreview()

我有什么方法可以异步地做到这一点吗？因为从Camerapreview活动到下一个活动只需不到一分钟.

编辑1:我们将预览尺寸从最高(1080x1920)缩小到中间范围(480x800),一切都开始正常.预览尺寸是否与HAL中的相机释放有关？

Our app underwent the google review process recently. We received a confirmation that the app has been approved and if we need to change it we'll have to undergo the review process again.

We tried to change the product logo URL after it was verified but in vain. It shows an error stating You do not have permission to perform this action. There is a link to update form which does not have the product logo URL field. ( …

以下哪一项会使用更少的内存？

$myArray = array();
$myArray[1] = array(1,2,3,4,5,6,7,8,9,10);
$myArray[2] = array(1,2,3,4,5,6,7,8,9,10);
$myArray[3] = array(1,2,3,4,5,6,7,8,9,10);

要么

$myArray = array();
$myArray[1] = array(1,2,3);
$myArray[2] = array(1,2,3);
$myArray[3] = array(1,2,3);
$myArray[4] = array(1,2,3);
$myArray[5] = array(1,2,3);
$myArray[6] = array(1,2,3);
$myArray[7] = array(1,2,3);
$myArray[8] = array(1,2,3);
$myArray[9] = array(1,2,3);
$myArray[10] = array(1,2,3);

array(1,2,3,4,5,6,7,8,9,10)并且array(1,2,3)可能不会在真实场景中重复.

如果我在CPU和内存利用率方面使用其他产品,那么性能会有提升吗？

我有一个主要活动A,它将调用另一个活动B,其oncreate()在下面提到.当我在活动B中按主页按钮并按下最近的应用程序时,永远不会设置标志FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY.我正在使用三星nexus 10(Android 4.4.2).

 protected void onStart() {
  super.onCreate(savedInstanceState);
  if ((getIntent().getFlags() & Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY) != 0)
  {
       //Call Main Activity.
  }
  else
  {
       //Continue creating this activity
  }
 }

当我将if块放在onCreate()中时,当我从最近的应用程序打开我的应用程序时,它永远不会被调用.

编辑1:让我解释一下我想做什么.每当用户使应用程序转到后台(锁定屏幕,按下主页按钮等)时,我想在应用程序到达前台时调用特定活动(用于身份验证).
