Hi @atultiwari, @YuriZheng,

We will look into making the adjustment to the NDK API 21 within the android-n-preview soon.

Hi @atultiwari, @YuriZheng,

We have made some changes in the android-n-preview branch which include adjusting the target platform used within the Android NDK. Please feel free to try the android-n-preview to see if it addresses the issue you are seeing. Thanks!

[atultiwari]

@developernotes thank you for your reply. I will try it in the evening and get back to you. It's 2 a.m. here, feeling very sleepy. But, on a quick look. I am unable to figure out how to use android-n-preview? I mean previously I was using aar in Android studio, like - compile 'net.zetetic:android-database-sqlcipher:3.4.0@aar'

But it seems, for android-n-preview I might have to compile sqlcipher myself, about which I have no idea.

Hello @atultiwari,

Yes, the android-n-preview branch is distributed in source only format. If you are interested in a zip build please feel free to email us at support@zetetic.net with your Discuss account.

[YuriZheng]

Hello @developernotes : I download the source and build it myself. But it has this issue, I'm a java developer, so i'm poor of c and c++. If you solved this probrem, please let me know! I'm very worried. Thank you very much !!!

Hi @developernotes ,

I am facing this problem using the latest version 3.5.4 on a sony device with android 5.0. net.sqlcipher.database.SQLiteException: error code 8: attempt to write a readonly database. Do you have any suggestions what I could try?

[developernotes]

Hi @heutschibogdan

Are you able to create a small reproducible test case within the SQLCipher for Android test suite? If so, we would be happy to look into that further. Thanks!

[heutschibogdan]

Hi @developernotes

I've added a test case for this. It seems the problem is not really related to the sony device, as I've reproduced it on multiple android versions which have x86_64 system image. It seems there is a problem when using an external storage in this cases.

Hi Team,

We are facing the below issue may be the similar as previous

net.sqlcipher.database.SQLiteException: error code 8: attempt to write a readonly database

Happens when app having multiple processes.

[sjlombardo]

@umesh0492 are you saying that the application works if there is only a single process, but fails when there are multiple processes, even if the database location is the same?

[ArikYa]

I'm having the same issue, also seems to be related to multi-processes application. Any update on this?

[developernotes]

Hi @ArikYa

What version of SQLCipher for Android are you currently using?

[ArikYa]

I use it through Requery, which uses 3.5.4

[developernotes]

Hello @ArikYa

Please try the latest version of SQLCipher for Android, which is 3.5.7 and let us know your results. Thanks!

[dotw]

Hello guys, I'm facing the same issue. I'm using the latest version 3.5.7 now.

Struggling several hours then I found the issue is the database path. I changed the path from context.getApplicationInfo().dataDir + "/databases/" + DATABASE_NAME to context.getDatabasePath(DATABASE_NAME).getPath() then, the exception is gone.
