SQlite无法在设备上正常工作

Question

I'm developing an app that uses SQLite database to store some info. When I run the app on an emulator or on my physical device plugger via USB from android studio, it works fine. However, when I use an APK version (send via email or installed from the play store) the database works but the insertRow command doesn't seem to work. All the other command seems to work for as far as I can test them. I already tried to uninstall-reinstall multiple times without success.

Answer 1

It appears that on a previous version of my database KEY_IMM to KEY_EXTRA10 were set as NOT NULL . Using (android:debuggable="true") allowed me to see it.
