Nixpkgs: Building a react-native Android project fails (gradle)

[PositronicBrain]

Is anyone using Nixos to build react-native projects?

The command ./gradlew build --stacktrace fails with error

com.android.builder.internal.aapt.v2.Aapt2InternalException: AAPT2 aapt2-3.4.1-5326820-linux 
Daemon #0: Daemon startup failed

And a some lines below:

Caused by: java.io.IOException: Cannot run program "/home/federico/.gradle/caches/transforms-2/files-2.1/2df53a66e454f1abff0680fcd8c73763/aapt2-3.4.1-5326820-linux/aapt2": error=2, No such file or directory

However said file is there:

Edit:

Running through ld-linux works

/nix/store/qn76sklvyalzw9ilnxz6sh0020gl2qn6-glibc-2.27/lib/ld-linux-x86-64.so.2 ./aapt2
error: no subcommand specified.

Am I missing something?

@PositronicBrain, I was able to work around this issue via this shell.nix:

{ pkgs ? import <nixpkgs> {config.android_sdk.accept_license = true;} }:

(pkgs.buildFHSUserEnv {
  name = "android-sdk-env";
  targetPkgs = pkgs: (with pkgs;
    [
      androidenv.androidPkgs_9_0.androidsdk
      glibc
    ]);
  runScript = "bash";
}).env

Make sure you kill your gradle daemon before entering!

Gradle gets the aapt2 binary from maven by default. That one wont work on nix so you need to specify the patched one from the androidenv sdk.

androidSdk = androidenv.androidPkgs_9_0.androidsdk;

Then on you project's gradle.properties (through env variables or appending via echo):

android.aapt2FromMavenOverride=${androidSdk}/libexec/android-sdk/build-tools/28.0.3/aapt2

That worked for me on a pure shell without having to use buildFHSUserEnv

this works for me:

{ pkgs ? import <nixpkgs> {config.android_sdk.accept_license = true;} }:

let
  androidSdk = pkgs.androidenv.androidPkgs_9_0.androidsdk;
in
pkgs.mkShell {
  buildInputs = with pkgs; [
    androidSdk
    glibc
  ];
  # override the aapt2 binary that gradle uses with the patched one from the sdk
  GRADLE_OPTS = "-Dorg.gradle.project.android.aapt2FromMavenOverride=${androidSdk}/libexec/android-sdk/build-tools/28.0.3/aapt2";
}

I documented this over at https://nixos.wiki/wiki/Android#gradlew

@dacevedo12, you are a lifesaver. I've been stuck on this particular error for 4 days.
