Database in Android Studio

[AndriannaT]

Hello,I have to make a Speedometer App. When I try to run it, it appears this message:

E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.myapplication, PID: 16450
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.myapplication/com.example.myapplication.MainActivity}: java.lang.IllegalStateException: getDatabase called recursively
at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2913)

I have use in my app getWritabaleDatabase. What the problem may be? Thank you in advance.

Are you sure that you have package your DB file into your apk? And is it in proper folder?
