VFY: unable to resolve virtual method

Question

I am using Jackson in my android app.

I have added these two jars in my build-path:

jackson-core-asl-1.0.0.jar
jackson-mapper-asl-1.0.0.jar
         


        

Answer 1

This can also happen if you have code calling methods that don't exist in the current device OS version.

For example, if somewhere in your app you call Settings.Global.getFloat(String) - which was added in api 17 - and the current device is running api 15, you will see this warning in your logs.

There will be a crash if you actually try to invoke this method. There is no problem if you don't call this method. So make sure you always check the current version before calling this.

    private float getAnimationSetting(ContentResolver contentResolver,
                                      String setting) throws Settings.SettingNotFoundException {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            return getAnimationSettingJB(contentResolver, setting);
        } else {
            return getAnimationSettingLegacy(contentResolver, setting);
        }
    }

    private float getAnimationSettingLegacy(ContentResolver contentResolver,
                                            String setting) throws Settings.SettingNotFoundException {
        return Settings.System.getFloat(contentResolver, setting);
    }

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
    private float getAnimationSettingJB(ContentResolver contentResolver,
                                        String setting) throws Settings.SettingNotFoundException {
        return Settings.Global.getFloat(contentResolver, setting);
    }
