android - 无法使用真实设备进行 react 开发

Question

我正在尝试使用我的手机进行原生 react 。但我得到一个奇怪的错误，似乎无法解决它。有人可以帮忙吗？这是堆栈跟踪:

<everything fine above>

:app:validateSigningDebug
:app:packageDebug UP-TO-DATE
:app:assembleDebug UP-TO-DATE
:app:installDebug

Installing APK 'app-debug.apk' on 'Aqua 4G+ - 5.0' for app:debug
Unable to install C:\Users\Mehul\Desktop\app\android\app\build\outputs\apk\app-debug.apk
com.android.ddmlib.InstallException: Failed to install all

        at com.android.build.gradle.internal.tasks.InstallVariantTas

<some more java errors>


02:58:27 E/427709463: Error while uploading app-debug.apk : Unknown failure ([CDS]close[0])
:app:installDebug FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:installDebug'.
> com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: Failed to install all

我只包含了必要的堆栈，以便于阅读。

Answer 1

I had to type:
adb kill-server

Wait a moment then run:

adb devices

In my case output is like are as follows

**List of Devices Attached**


*0123456789ABCDEF   device*

This will show you the DEVICE_ID (0123456789ABCDEF) of your device running android. 

then you will have to run below command and make sure usb is enabled 

react-native run-android --deviceId 0123456789ABCDEF

After that my output be like 


    **D:\React\albums>adb devices

    List of devices attached
    0123456789ABCDEF        device

    D:\React\albums>react-native run-android --deviceId 0123456789ABCDEF

The important part was the --deviceId XYZ. Without this, the apk would never get uploaded to the phone.

**First Way**

*** If you are using Latest version of React then shake your real device and press reload (In my case react-native cli version is 2.0.1 And react-native version 0.45.1 ) Dont put any machine address and port in dev setting ok ***


**if first method does not works then follow second method**

**Second Way**

Then, the app launched with a red screen... i had to shake it, dev settings, adjust the "debug server host & port for device", putting my computer's IP address and port, like this:

192.168.0.15:8081

Lastly, i had to shake my phone again and select RELOAD...
