android - can't access SDCARD at the starting time of device in livewallpaper -


The wallpaper in which I am displaying data from the database, which is actually in the SD card

- firstly If I want to use data I have put some bet on sdcard 

  if (Environment.getExternalStorageState (.) Equals (Environment.MEDIA_MOUNTED)) {  
 this is okay, now when I restart my device at the startup time of my device, then my wallpaper wants to access the database, so that It will first check the condition, but it will return  FALSE   
  It may be that the SD card has been mounted shortly after the start of the Android OS. ..   
 So can someone suggest me how to solve this issue, because the large size database is to put on the SDCARD  SDCARD < After / div> 
 
 
 
 It may be that Android has been installed after some time OS   
 Yes to register properly, so  action. MEDMount  The HeN SD-card has been mounted to receive broadcast recipient transmissions.  
 The first register in AndroidManifest.xml is BroadcastReceiver:  
   & Lt; / Intent-Filter & gt; & Lt; / Receiver & gt;   
 Do your work within the onReceive method in the ExternalStorageInfoReceiver:  
  Public Square ExternalStorageInfoReceiver extends BroadcastReceiver {@Override Public Zero onReceive (reference reference, intent meaning) { / / Change the wallpaper ....}}

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon.
