Crash: Could not create folder .../cache/rollbar-items

Hey, do you maybe have an idea, why our apps are crashing?

Exception java.lang.RuntimeException: Unable to create application com.xxx.app.CustomApplicationClass: java.lang.RuntimeException: Could not create folder: /data/user/0/com.xxx.app/cache/rollbar-items

It seems that it crashes when I initialize Rollbar in my CustomApplicationClass:

public class CustomApplicationClass extends MultiDexApplication {

  @Override
  public void onCreate() {
    // Rollbar initialization
    Rollbar.init(this, getResources().getString(R.string.rollbar_access_token), getResources().getString(R.string.rollbar_environment));

    super.onCreate();
  }

  @Override
  protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
  }
}

hi @malua ! I was trying to reproduce the error but so far I couldn't, could you share more information with me? like, are you testing it on an emulator or a device? with what api? Did you try the example app and it also produced this error?

This happened a lot in our production apps. I removed the rollbar sdk from android, when I created the issue. But I could not reproduce it locally. I thought you can maybe do more with the error message than me.
