I use a realm database in my android project.
I've added a new column to my realm db which I generate out of a CSV and did the same in my entity file.
However, I now get a RealmMigrationNeededException if I start my app although I have uninstalled it before. So it seems like if my generated database and the entity file don't match.
I would like to know if it's possible to find out what exactly causes the exception. The stacktrace I get in Android Studio doesn't contain any clues which might help me to resolve the issue

Is there any proper way to debug a RealmMigrationNeededException except for trial and error?
If a RealmMigrationExceptionNeeded error happens, Realm automatically tries to trigger any configured migration to fix it. If no such RealmMigration exists, you instead get another RealmMigrationNeededException that overrides the underlying cause.
The fix is to just provide a dummy RealmMigration to see the real error.
I can see why it can be a bit confusing, and we should probably consider throwing a better exception message that also include the underlying cause.

I'm getting following exception if sometimes thought of posting it after a month. Every time I have to delete build folder and error goes away. So it is risky to stay like this condition for long run, as sometimes developer might forget to check this activity is opening or not.
So far strangely it is only happening with one file ProductListActivity.kt
This runtime error looks like common error Is there a Gradle configurations needed to fix it.
How to completely get rid of it?

What i can see from the logs that you are using kotlin, so instead of butterknife you can replace your code with view binding(area which are getting error)

I'm trying to insert values to the database on SQLite by SQLiteOpenHelper bur the app closes.
I'm working with SQLiteOpenHelper on Android studio, and using an activity to insert values in the database, when I first enter to the activity I can insert all the values I want, but when I go out, re-enter the activity and press the button "Registar" that insert the values on the table, the app closes without showing the Toast message.
public void Registrar (View view){
Toast.makeText(this,"Entro al registrar",Toast.LENGTH_SHORT).show();
AdminSQLiteOpenHelper admin = new AdminSQLiteOpenHelper(this, "administracion", null, 1);
SQLiteDatabase bd = admin.getWritableDatabase(); <- in this line close

I only expect to insert the values even if it's the second ot third time I enter to the actitity.
The cause is that before the failed run the database had had it's version number set at 5 but you are now trying to use version 1 without overriding the SQliteOpenHelper's onDowngrade method; which without being overridden results in the encountered exception, as is intended, as reducing the version number is generally not done.
That is AdminSQLiteOpenHelper admin = new AdminSQLiteOpenHelper(this, "administracion", null, 5); was used but now AdminSQLiteOpenHelper admin = new AdminSQLiteOpenHelper(this, "administracion", null, 1); has been used (4th parameter was 5 but is now 1) .
You could fix this by again using 5 as the version number.
Another fix could be to uninstall the App or delete the App's data and then rerun the App without changing the version. Noting that this would result in all data being lost.
Yet another fix could be to override the onUpgrade method (perhaps doing nothing), the version should then be set to 1, the data would be kept.
There are other ways of fixing this issue but they would be a little more complicated and offer no advantage over the mentioned fixes.
In a recent update we began seeing 2 crashes coming from Firebase. Neither of these crashes are reproducible, and they happen pretty infrequently, but frequently enough for us to be concerned. The first one appear 99% of the time on Android 7 (1% on Android 5):

Unfortunately the Firebase SDK is obfuscated so I can't see the full context of the crash, but the exception being thrown is an NPE on a NetworkInfo object trying to perform the isConnected method.
These are the firebase libs we are using in this build:
api "com.google.firebase:firebase-config:11.6.2"
api "com.firebase:firebase-jobdispatcher:0.8.4"
We upgraded the firebase-config lib from 11.2.0 to 11.6.2 and added the jobdispatcher lib between the previous release and this new release where we began seeing the crash. I've searched around but haven't seen any existing conversations about the issue, if anyone has insight we'd really appreciate it. Thanks!
I got an official answer from the firebase team to the bug report I sent concerning this issue:
Yes, you are right. This is currently an issue from Firebase SDK 11.6.0 onwards.
Our engineers are currently working on a fix for this issue, but I can't share any details or timelines at this time.
In the meantime, I would suggest you to use the older version of the Firebase SDK.
You may check our release notes for any further updates.
Had same issue. Fixed in Firebase SDK 11.8.0.
Also checked the release notes:
SDK Version 11.8.0 - December 18, 2017
Cloud Messaging
Fixed an internal NullPointerException caused by a call to NetworkInfo.isConnected().
I write an android App Widget and it works fine. After some time I had to change its package name But it works well yet. I already had getPackageName, and it prints the correct package name in the log, and still sometimes after I upgrade the app (or just run it on the device from AndroidStudio) the widget disappears. Later it got back after another upgrade.
this is my logcat :

This question already has answers here:
RuntimeException: Unable to instantiate application
(14 answers)
Closed 5 years ago.
I have a question. When project is run, I rarely get fatal exception.
I have two different android applications in the same project for different build variants. But their package name are different.
In manifest file, my first application's package name is written. I rarely get fatal exception, when I run my second project.
How can I fix this error?

You should control your architecture, does anywhere else control your build variants or have your project any xml file regarding build-variants as static string.
