由 筅森魡賤 提交于 2019-12-05 12:34:15
I wanted to know whether reinstallation of app deletes SQLiteDatabase or SharedPreferences in Android. Also under what circumstances does it gets deleted. Application will be downloaded from server & installed. If it does get deleted what should we do to take a backup & restore it again? Please help... No... Database and SharedPreferences will not be deleted if one reinstall the app. They get deleted when some one uninstall it or clear data from settings menu of device... Updating your app (installing newer or the same version) will keep you preferences and all data, unless you do not

Create Azure VM from image created under different subscription

由 两盒软妹~` 提交于 2019-12-05 05:26:49
Is there a way to take a backup of a VM (image capture following the sysprep method) and then make that image in the gallery visible to someone under their subscription. For example, I create a VM, archive it off to the image gallery, then my colleague comes along and wants to create a VM from that image (the colleague cannot be a co-administrator on my subscription). Alternatively, is there just a way to move the VM to a different subscription without archving it off and recreating? Have found the following but this is a bit convoluted and requires purchase of third party software http:/

Restore Vim Backups

由 那年仲夏 提交于 2019-12-05 01:07:59
Vim's file backup system just saved my proverbial @$$ but I have a question. I have vim saving backups to ~/.vim/backups To restore them I went to the directory and (sorted by date) copied the files I needed back to the necessary directories in my project folder. Easy enough, there were only 5 files. However, I'm surprised there's no obvious way to find which directory each file came from. I tried using vim -r path/to/file but that seems to use the swap and not the backup file. Since in my case vim didn't crash (I just mistakenly overwrote the files) there is no swap for these files. So the

问题 In my In App purchase the case SKPaymentTransactionStateRestored: method does not get called when the purchase is restored, instead, case SKPaymentTransactionStatePurchased: is being called, but would like to show the user different information, when the purchase is restored. 回答1: [queue restoreCompletedTransactions] will trigger SKPaymentTransactionStateRestored state, where queue is SKPaymentQueue. You should not expect this to be called after your user confirms transactions. Instead user

How to locate and recover a deleted file

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-04 16:39:41
问题 At some stage in the past I had a "foo.txt" which was under Mercurial source control. However it has now been deleted. How can I recover the file when I don't know the last Mercurial revision in which the file was deleted? 回答1: If you know the exact path for the file, you can do something like : hg log -l 1 path/to/foo.txt This will show you the last changeset where foo.txt was modified, so you will be able to restore the file from this revision. Once you have the right revision, you can

Storing entire process state on disk and restoring it later? (On Linux/Unix)

由 梦想与她 提交于 2019-12-04 16:26:22
问题 I would like to know: Is there a system call, library, kernel module or command line tool I can use to store the complete state of a running program on the disk? That is: I would like to completely dump the memory, page layout, stack, registers, threads and file descriptors a process is currently using to a file on the hard drive and be able to restore it later seamlessly, just like an emulator "savestate" or a Virtual Machine "snapshot". I would also like, if possible, to have multiple

Problems restoring to multiple devices using Android BackupManager

由 人走茶凉 提交于 2019-12-04 10:13:11
I've implemented backup/restore of SharedPreferences using BackupManager as per the Android docs , but I'm having trouble restoring preferences to a second device. I believe the implementation is fine, since I can restore settings to a single device, i.e. if I run the app, make changes, uninstall and reinstall I get the modified preferences that I expect. However, if I subsequently install the app on a second device, I don't see the changes, even if I use the bmgr tool to force a backup on the first device and force a restore on the second device. Both devices have the same Google accounts,
