I am on Android O and using Room database, from time to time, I experience SQLiteDisckIOException, I try to troubleshoot problem but the stack doesn't tell me where the failing point is. Can some give me some hint or how to troubleshoot this kind of problem and what is the potential problem here? The app that I am writing will write to database when location change, and also there are couple background task that periodic update database when needed.
Here is the stack I see:

From the SQLite documentation SQLITE_IOERR_SHORT_READ refers to a case where the database was unable to read the requested number of bytes from the file system.
https://www.sqlite.org/rescode.html#ioerr_short_read
Do you allow your apps to be installed on the external storage directory ?
https://developer.android.com/guide/topics/manifest/manifest-element.html#install
My guess is that:
Either the file system on the device is problematic.
The app was in an external storage directory, and the SD card was removed while the user was using your app, and that caused SQLite to throw this exception.

I copy/paste the already created .db file to my android studio project, but it is crashing my app. That database file is working fine on another android studio project but it is giving exceptions and causing the app to crash on my current project. Following is the logcat

plz someone tell me what is the problem or what i have done wrong. Thanks
Every project has its own database may it be Room or Sqlite once you build your project the database will be created locally, so it is unique to the project and your need to add elements manually. What you did is you brought that file to another project and the query which you wrote is very SUS cause your present project database do not have any id:2 entry so it is failing.
You cannot just cut and paste the database into the project. For such a pre-existing database you would typically copy and paste the database into the assets folder and then use an adapted custom class that extends SQLiteOpenHelper (from your stack trace Databases.DatabaseHelper).
This adapted custom class MUST, in addition to the usual implementation have code that will:-
check to see if the database already exists.
if the database file does not exists copy the database file from the assets folder to the ultimate location (typically data/data/<the_package_name>/databases/<the_database_file_name)
Should the database then not exist (if no exception has stopped the app) or if the database is corrupt then the database will be created WITHOUT anything but the sqlite_master table and the android_metadata table, so effectively , from the user/developer viewpoint, an empty database and hence a table not found.
I would suspect that this is what is happening.
However, another scenario where this can happen if exceptions are caught/trapped and allow processing to continue. Is when the SQLiteDatabase's getWritableDatabase or getReadableDatabase are used for later Android versions when WAL (Write-Ahead Logging is the default). In short this creates a -wal file, which is NOT owned by the original database file created by the methods as that database file has been overwritten by the one copied from the asset. The too friendly openOrCreate method used then sees the corrupt database and gives you a new database devoid of any tables.
It is suggested that one of the above is the issue that you face. Although a bit over the top this may be of use.

You did not provide additional details if it is working on other devices or how the model was generated. I have faced this error before. It is likely not device related. Based on the error log it seems you are using this repository for object detection task with yolov4 tflite model.
java.lang.IllegalArgumentException: Internal error: Failed to run on the given Interpreter: Next operations are not supported by GPU delegate:
EXP: Operation is not supported.
SPLIT: Operation is not supported.
SPLIT_V: Operation is not supported.
Use tf.lite.OpsSet.SELECT_TF_OPS in converter.target_spec.supported_ops when converting saved model to tflite. Also in build.gradle use any one of the below,
implementation 'org.tensorflow:tensorflow-lite-select-tf-ops:2.3.0'
implementation 'org.tensorflow:tensorflow-lite-select-tf-ops:0.0.0-nightly'.
This will increase apk size but this can solved with selective build of tensorflow-lite-select-tf-ops.aar.
Below is the details of the exception that is according to different Android devices and unable to find any soliton for it.
I get these details from Firebase Crashlytics as I am unable to reproduce it and is the most frequently according to crash in my Firebase Crashlytics list

We used Firebase Database to synchronize data and we found an exception in crash report. Here is brief log:
Caused by com.google.firebase.database.DatabaseException:
Failed to gain exclusive lock to Firebase Database's offline persistence.
...
Caused by android.database.sqlite.SQLiteDatabaseLockedException: database is locked (code 5): ,
while compiling: PRAGMA journal_mode
More detail log is here. Here is our Firebase Database init code
// run in Application onCreate method
FirebaseDatabase.getInstance().setPersistenceEnabled(true);
Mostly, HTC mobiles with API level 19 are impact. We try to reproduce this
bug, but fail.
i got lots of crashes on lots of devices but on my device(lg p920) it works fine. the below report is from goggle play my app crashed and got 6 reports. by the way i use sql pre created database.and also created android_metadata table and locale en_US also inserted to that database.

One thought that popped up is the hard coded path to where the
database file is located. DB_PATH =
“/data/data/YOUR_PACKAGE/databases/”;
I guess it is possible that this path isn’t valid on Android 2.2.1 for
Desire HD. I exchanged this path with: Environment.getDataDirectory()
+ “/data/YOUR_PACKAGE/databases/” + DB_NAME;
I’ll try to pin point the issue when I had the chance to test on the
actual phone myself. If anyone test this solution, please let me know
if it solves it.
This is not a common error you'll see. It can happen rarely on some device with low internal memory. While your app was trying to write to DB, it ran out of internal memory and failed to write. What you can do is check the available storage and if its really dropping to zero, notify user.
