QUESTION
The app has:
- ListView listing player names from a DB table (only one column, so it is primary key)
- EditText to write the new name
- Button to update the name of player in the list
*there are more things, but i don´t want to make it more messy
I can click a name from the list and write a new name in the EditText. When you press the button that name is updated in the list.
Everything works correctly, but there is a problem. When I write a name that it is already in the list the app fails because primary keys cannot be repeated.
Is there some way to say "if EditText text already exists in the DB... then show a toast"
I already tried "if result of db.update is -1...then show a toast", but it doesn´t work.
This is the method in MainActivity:

You have a UNIQUE index on the NUM_JUG column (perhaps implicit if NON_JUG is defined with PRIMARY KEY) and you are using the standard update method which uses the default conflict action of ABORT and therefore fails if an attempt is made to duplicate a NOM_JUG value.
As secondary issue is that the SQLiteDatabase update method returns the number of updates (see extract and link below) (same for updateWithOnConflict). The number returned will never be -1 it will be 0 or more (0 indicating that no updates have been applied).
As per SQLite Database - Update
Returns
int the number of rows affected
Fix
To fix the main issue you should use the updateWithOnConflict method. This takes a 4th parameter a conflict and you probably want IGNORE so you could use :-

I run my Android app (based on Java), and it works. Next, I add to my app code:
FirebaseFirestore fdb = FirebaseFirestore.getInstance();
This code I got from the official Android site https://firebase.google.com/docs/firestore/quickstart
App runs, but next the running device shows the message "app has stopped".
I use a device simulator available in Android Studio.
It is my first Android app, and I can't understand what is going.

...ANSWER
Answered 2021-Jun-09 at 03:39At the end of your log, just before the initial crash. there is a warning:
Default FirebaseApp failed to initialize because no default options were found. This usually means that com.google.gms:google-services was not applied to your gradle project.
simply adding com.google.gms:google-services should fix any issues you have, if you have issues, ensure your Gradle cache is cleared or run without the build cache

QUESTION
I'm working on a capacitor app that uses capacitor-firebase-auth for phone auth using firebase. The app now has thousands of users and for the vast majority everything works fine. However, a few users per day are not able to login with phone number, and most of them are using a custom ROM like lineageos.
In order to debug the problem, I installed lineageos on one of my devices. Logcat of login with phone number looks like this:
...ANSWER
Answered 2021-Jun-02 at 06:14ok, I found the solution: for some reason, google-services.json did not include my play store signing SHA1 key, despite it being present in firebase admin console. Solution: I removed the SHA1 key and added it again... Afterwards, google-services.json included my release SHA1 and phone auth works even on lineageos.
Apparently SHA256 is required for phone verification using safetynet which works on standard androids, and SHA1 is only required for the recaptcha flow which is required on non-standard androids. This explains why it worked for the vast majority of users.

Answered 2021-May-27 at 21:54You didn't tell ffmpeg what to do with the audio so it just picked the audio from the first input (see stream selection).

I have an issue in a yocto based embedded linux system. I have tracked it down to an interaction between dbus and SELinux, and using dbus-monitor I can see the following error:
...ANSWER
Answered 2021-May-27 at 10:16Further research shows that dbus itself is an SELinux aware application. It is checking the SELinux configuration, and taking enforcement actions within dbus itself. This accounts for why the denials from dbus do not appear in the audit log, even when silent denials are turned off.
My particular issue was solved by adding some allow rules for 'send_msg' as follows:

QUESTION
I am trying to open the /dev/diag using JNI as open("/dev/diag", O_RDWR | O_LARGEFILE | O_NONBLOCK); but returning errno: 13 Permission denied.
What should be done to make this work?
When checking the ownership of the /dev/diag using the command ls -l /dev/diag it returns crw-rw-rw- system qcom_diag 244, 0 2015-01-14 01:47 diag
and when trying to use the command id i get uid=0(root) gid=0(root) groups=0(root) context=u:r:init:s0
So I thought the problem is related to ownership?
Update: Based on @HamidShatu answer
I tried to set the SELinux to permissive with no luck.
I tried the command su 0 setenforce 0 it returns OK while still being Enforcing if checking immediately using getenforce command.
I even tried to change the prop.build: this file did not exist instead a prop.build.bak did so i copied it modified the SELinux to 0 instead of 1 and pushed it without the .bak extension. Even i checked with external applications that modify the prop.build where the SELinux is set to 0 but when checking with the getenforce command it is still returning Enforcing
here is the extract of the dmesg:
...ANSWER
Answered 2021-May-17 at 14:48To understand/analyze your issue, maybe we can first look into what you have posted here.
I am trying to open the
/dev/diagusing JNI asopen("/dev/diag", O_RDWR | O_LARGEFILE | O_NONBLOCK);but returningerrno: 13 Permission denied.
From my experience, errno: 13 Permission denied suggest that your code is doing some SELinux violations.
When checking the ownership of the
/dev/diagusing the commandls -l /dev/diagit returnscrw-rw-rw- system qcom_diag 244, 0 2015-01-14 01:47 diagand when trying to use the commandid, I getuid=0(root) gid=0(root) groups=0(root) context=u:r:init:s0
This portion clearly suggest that /dev/diag directory belongs to Qualcomm. According to Android Treble re-architecture, there are 3 main partitions belong to:
- Android system (Google/AOSP)
- Vendor (Chip maker) &
- OEM (Device maker)
So, according to your analysis, /dev/diag belongs to Vendor partition.
So I thought the problem is related to ownership?
The answer of this question is pretty much: Yes.
What should be done to make this work?
You need to add SELinux permission to make this work.
As crw-rw-rw- system qcom_diag 244, 0 2015-01-14 01:47 diag line suggests, you need to add a SELinux permission to access qcom_diag from system for diag.
Here's one thing is that, any kind of diag permission is given only in Debug build, not in User build. Because giving SELinux permission for diag in User build will raise a security concern. It can leak vital information by printing them in logs.
