after I downloaded the new version of android mode for processing 4 wrote a simple program and when I tries to test it I got

```auto
Exception in thread "Thread-27" java.lang.NoSuchMethodError: 'java.lang.String processing.mode.android.AndroidBuild.preprocess(java.io.File, java.lang.String, processing.mode.java.preproc.PdePreprocessor, boolean)'
	at processing.mode.android.AndroidBuild.createProject(AndroidBuild.java:252)
	at processing.mode.android.AndroidBuild.build(AndroidBuild.java:223)
	at processing.mode.android.AndroidMode.handleRunDevice(AndroidMode.java:276)
	at processing.mode.android.AndroidEditor$16.run(AndroidEditor.java:412)

```

I then deleted all the code in the sketch and tried again and got the same error.

a brief look at the code seems to reveal that this method does not exists

Last I remember processing 4 is incompatible with android mode. You have to downgrade to processing 3.

I issue was not produced when I downloaded the latest processing-4.0b8 with downloading Android Mode for Processing 4 (version 4.5.0 a4) and I’m able to run an Android Mode’s example Array code successfully on the device.

I need the following information @jSdCool @PoYo -

- Processing4 version
- OS on which you are using the processing4
- Android Modes version (In windows you can check Android Mode version in `C:\Users\User\Documents\Processing\modes\AndroidMode\mode.properties` file. Check prettyVersion)
- If you can provide the sample program which produces the issue, that would be helpful.
- How did you test it? Did you use the play button to run the app on the device?

Best,
