# build as standalone android app(old)

2015/10/26

for creating standalone apk tool is in progress now. so, I try to create standalone flutter apk from flutter build environment.

ex : create "test" app

## (1) create flutter build env

* [build flutter](https://github.com/kyorohiro/hello_skyengine/tree/f7adfa70d1ddf4043d86b74dfb916ee33bed6102/build_android/build_flutter/README.md)

## (2) modify BUILD.gn on examples

flutter/src/examples/BUILD.gn

```
group("examples") {
  testonly = true

  deps = [
    "//examples/fitness",
    "//examples/game",
    "//examples/mine_digger",
    "//examples/stocks",
    "//examples/test",
  ]
}
```

## (3) create app project

* draw test

  <https://github.com/kyorohiro/hello_skyengine/tree/master/test_android>
* draw image

  <https://github.com/kyorohiro/hello_skyengine/tree/master/test_android_2>
* draw image and icon

  <https://github.com/kyorohiro/hello_skyengine/tree/master/test_android_3>

project folder name is "test"

```
./examples/test/lib
./examples/test/apk
./examples/test/...
..
..
```

## (4) build on flutter/src

```
./sky/tools/gn --android
ninja -C out/android_Debug
```

## (5) install apk

```
adb install -r ./out/android_Debug/apks/test.apk
```
