@akenaton Lollipop also requires this permission. The app APDE, (entirely based on Processing for Android) has an extra feature. It can run in a “preview” mode. Preview mode skips several steps of the build process: DX-Merge , APKBuilder, ZipSigner, and installation. The only significant remaining steps are AAPT, ECJ , and DX-Dex, so the build process is much more streamlined. The preview mode also gives automatic permissions. But when you want to export, using the “app” mode, permissions are required. On a Galaxy S9+, the entire process to run code, takes less than two seconds. Codeanticode was talking about implementing it in PC android as well. APDE is a free open source project from calsign and I really would ike to see them together on one Github. I was never able to run Processing for Android in emulator mode. And running on device directly with a usb cable, takes minutes every time. You could give it a try☺.
