When using Realtime Database on Android, on first initialization of Firebase, we get the crash. Caused by android.database.sqlite.SQLiteException: cannot rollback - no transaction is active (code 1) at android.database.sqlite.SQLiteConnection.nativeExecute(SQLiteConnection.java) at android.database.sqlite.SQLiteConnection.execute(SQLiteConnection.java:562) at android.database.sqlite.SQLiteSession.endTransactionUnchecked(SQLiteSession.java:439) at android.database.sqlite.SQLiteSession.endTransaction(SQLiteSession.java:401) at android.database.sqlite.SQLiteDatabase.endTransaction(SQLiteDatabase.java:555) at com.google.firebase.database.android.SqlPersistenceStorageEngine.endTransaction(SqlPersistenceStorageEngine.java:810) at com.google.firebase.database.core.persistence.DefaultPersistenceManager.runInTransaction(DefaultPersistenceManager.java:246) at com.google.firebase.database.core.SyncTree.setQueryInactive(SyncTree.java:472) at com.google.firebase.database.core.Repo$8$1.onComplete(Repo.java:535) at com.google.android.gms.tasks.zzj.run(zzj.java:4) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:457) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:301) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1162) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:636) at java.lang.Thread.run(Thread.java:764)

Hi @kashi1982 The error logs seem caused by Android API. You can also check this entry in Stackoverflow about a similar issue. Also, a good option is to check the Firebase Android quickstart, there is an example on how to implement the service. This project has been already tested and you can use it to test and compare your own implementation.

Feel free to leave a comment If the issue persists using our native SDK .
