如何修复应用程序没有在我的移动设备上安装已编译的apk，使用生成signed-react的react-native

Question

I currently new developing android react-native, I have problem regarding deploying my application on other mobile device, I read the documentation of react native How to generate signed APK, i did the instruction of there document

React Native signed-apk-android

I already done configuring those requirements based on there document. I will show you the step that I did.

First: Install this in the cmd

keytool -genkeypair -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

Second: Setting up gradle variables

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore

MYAPP_RELEASE_KEY_ALIAS=my-key-alias

MYAPP_RELEASE_STORE_PASSWORD=123456

MYAPP_RELEASE_KEY_PASSWORD=123456

Third: Adding signing config to your app's gradle config

    ...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

Lastly: Generating the release APK Simply run the following in a terminal:

$ cd android
$ ./gradlew assembleRelease

Before I do the installation, I gonna make sure that the package clearly uninstalled on my mobile device.

你需要点击apk（可能是开发者模式激活，按设置菜单中的内部版本号几次）
