Zygote The String#value field is not present on Android versions >= 6.0 Android error

Question

I'm using the Google API to build a maps application. I get this error:

E/zygote: The String#value field is not present on Android versions >= 6.0

I do not know how to get rid of this. I have searched in all sites including this:

The String#value field is not present on Android versions >= 6.0

Also no solution was published.

But I'm not using any kind of fire base. I would appreciate any kind of help.

Logcat with the error:

Nop. It still there. But it seems the project is functional. — Roga Lu, Jul 17 '18 at 20:14
Yeah, seems you're right. For future reference, my main issue seemed to be the fact that I was re-using my old mechanism based on MapView. Once I switched over to a SupportMapFragment as stated in the documentation, it started working again. — ItWillDo, Jul 17 '18 at 20:51
@RogaLu, Facing the same problem, please let me know if you find any solution to this. though the project is working fine. — Jay Dangar, Sep 26 '18 at 07:30
No solution, I finished the project and did not fix it. Sorry good luck. — Roga Lu, Sep 27 '18 at 22:08

I had a similar problem when running my app on Android 9. This SO answer worked for me: https://stackoverflow.com/a/52181547/6363572

You can try adding the following line in AndroidManifest.xml:

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

I had a similar problem, and it was resolved by running it in an emulator with Google Play enabled and updated. (Google maps will not run without an updated Google Play Store.)

Basically create a new Virtual Device that has Google Play (not just Google API). Alternatively, use USB debugging with an actual device.

See This Question for details.
