cannot backup on Android 7 Nougat

[takiainen]

I'm currently running CM14 based TugaROM and just noticed that while restoring backups goes as usual, I cannot make new backups. It just loops the circle animation for ever and says "backup", but nothing happens. I have to force close the app. The app has storage permission.

[takiainen]

Here's log (but it shows just one line after starting the backup)

Doesn't work on Slim7 either. First tried using the toybox that came with the rom, and then installed busybox too. But backing up just doesn't work.

Any ideas?

[jensstein]

sorry for the late reply. could you make a logcat with this apk: https://drive.google.com/file/d/0B0bNUNWd2wPPd0ZSb0FIWHg1eXc/view?usp=sharing it has a lot of logging so we can hopefully pinpoint where the issue starts.

[takiainen]

No problems! Here we go (I included everything it produced, then after a while I just killed the app):

great. so this is both an attempt at a fix and some more logging if it doesn't work: https://drive.google.com/file/d/0B0bNUNWd2wPPTzRvaWZTd2JFNFU/view?usp=sharing

[mddvul22]

I appear to have the same issue on nougat. Let me know if you need another tester.

Thanks again @jensstein for the great app and support. Been a happy oandbackup user for several years now!

[jensstein]

could you try running this command in a terminal and see what happens: cp -RL /data/user/0/org.smssecure.smssecure /storage/emulated/0/oandbackups/org.smssecure.smssecure this is the command oab tries to run when it stalls.

@78c59635bdd8 you could try running the same apks as @takiainen and if your logcat shows that another breakpoint has been reached i would like to hear it. thanks for your support :)

[mddvul22]

OK, looks like I got the similar output. This is with your most recent apk, posted in this thread, trying to backup the Lightning browser (both data and apk):

By the way, this may not be relevant to note for you, but this is a factory image of Nougat, straight from Google (except for being rooted and having TWRP).

[takiainen]

Actually I tried the command already before once I saw the last log, and the command runs fine. It copies the org.smssecure.smssecure folder.

[takiainen]

One more thing: I need to run the command as root. Otherwise it says permission denied.

[mddvul22]

@takiainen , when you backed up that data on the command line, did it show up in oandbackup as a new backup for that app? I thinking, as an interim workaround, to just create a shell script that I can run as root to do all of these backups and then use oandbackup for restores?

[takiainen]

oandbackup seems to store the backups as a zip file, which this command naturally doesn't create. So if your script makes the the compressed file also, then I don't see any reason why the restore process should not work. Please share the script if you make one!

@jensstein Any news regarding this issue? Did it turn out to be more complex than assumed? thx

[mddvul22]

@takiainen I'll have to wait for jensstein. I tried making a zip file of one app. Oandbackup seemed to restore it, but my customized settings in the app were gone. Hopefully jensstein can figure out what is going on. @jensstein let me know if I can do anything else to assist.

[jensstein]

sorry, i just have en acute lack of time. and yes, it's not entirely clear why it stalls. but please try this one: https://drive.google.com/file/d/0B0bNUNWd2wPPQlB6WkxBRUtNTWs/view?usp=sharing

@78c59635bdd8 if you want to script the backup process you should do three things: 1) make a directory under the backup directory with the package name of the app in question. e.g. dk.jens.backup 2) zip up the data directory of the app. e.g. /data/user/0/dk.jens.backup 3) make a metadata file and put it next to the zip. it should be named after the package name and end in .log. it should have contents like this:

{
    "label": "oandbackup",
    "versionName": "0.2.11",
    "versionCode": 17,
    "packageName": "dk.jens.backup",
    "sourceDir": "\/data\/app\/dk.jens.backup-1\/base.apk",
    "dataDir": "\/data\/user\/0\/dk.jens.backup",
    "lastBackupMillis": 1471770751198,
    "isEncrypted": false,
    "isSystem": false,
    "backupMode": 3
}

backupMode should be 1 if you only have apk backed up, 2 if you only have data and 3 if you have both apk and data. let me know if you have any problems :)

[takiainen]

The latest version FC's right from the start. I mean the app doesn't start at all. Cannot take log either.

But thanks anyway for managing to find some time for this! We are not in a hurry.

[jensstein]

apologies, that was too hasty. this one should work: https://drive.google.com/file/d/0B0bNUNWd2wPPTjJ3T25KaEVQd2c/view?usp=sharing

Thanks @jensstein. Unfortunately, it looks like the same results:

I opened the app again and attempted a backup one more time, this time I let the backup job go for longer, while still running the logcat. I saw some stuff after some additional time that might , or might not be helpful:

Doesn't work here either. Here's the log.

I can reproduce this issue on my Nexus 5 running CM14.1 with similar logs as above.

[alexbarcelo]

Another Nexus 5 user here running CM14.1. My output, which is very similar to the last two provided logs (but using backupmode 3). Sorry if I'm being noisy in the GitHub logs, don't have much more to contribute right now:

CM14.1 is a nightly (from two days ago more or less). The busybox has been installed through the ru.meefik.busybox package (BusyBox package at F-Droid).

[jensstein]

thanks for the input from you all. i will try installing android 7 on one of my own devices tomorrow and see if i can reproduce the issue myself. i think i need to have my hands on it to fix this.

[jensstein]

does this one work: https://drive.google.com/open?id=0B0bNUNWd2wPPTjJ3T25KaEVQd2c (i know the link is the same as the last, but the file should be different. md5: 9534d56c5d145f3cc2cfdd866d0a24f9)

[mddvul22]

@jensstein you fixed it! I tested both an apk only backup and a backup of apk+data. In the app that I backed up apk+data, I modified some data just before taking the backup. Both jobs completed! I deleted both apps and then restored from the backups I had just taken. Both restores worked, of course. For the app that I had backed up apk+data, the recently modified data was restored. Great job!

[takiainen]

It indeed works, thanks a lot ! Mind sharing what was the problem? And will you push this to F-Droid to let others continue to enjoy it too on Nougat?

[grawlinson]

@jensstein I can confirm that your latest version works as intended (md5: 9534d56c5d145f3cc2cfdd866d0a24f9)

Thank you.

[jensstein]

great :) the problem was just that the output stream wasn't flushed after writing the last command. i had just forgotten about it in the code that does the backups - all the other places that call external commands have flushing. so it was a one line fix.

i will make a release sometime soon so people using f-droid also get the fix.
