React Native Android：请求可在android模拟器中运行，但不适用于Play Store构建

Question

I have a React Native app that is making a simple sign in request. This request works in the ios simulator and works when I install the build onto my device. It does not work when I download the app from the Play Store.

I have tried the following: I have re-installed and installed the app. Looked at production logs, I don't see any record that the request reaches the rails server. I have been using bugsnag logging.

Here is the request:

sendLoginEmail = (isResend) => {
    bugsnag.notify(new Error(`1: ${this.state.email}`))
    enterEmail(this.state.email).then(response => {
      console.log("sle response!")
      console.log(response)
      bugsnag.notify(new Error(`2: ${this.state.email}`))
      bugsnag.notify(new Error(JSON.stringify(response)))
      if (response.status === 200) {
        this.setState({isEmail: false, isLoading: false, warningMessage: isResend ? "Email resent" : null});
      } else {
        this.setState({isLoading: false, warningMessage: "Something went wrong. Please try again."})
      }
    }).catch(response => {
      bugsnag.notify(new Error(JSON.stringify(response)))
    })
  }

enterEmail looks like this:

export const enterEmail = (email) => {
  return fetch(`${host}/v2/users`, {
    method: 'POST',
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      user: {
        email
      }
    })
  })
}

Bugsnag logs the first error ( bugsnag.notify(new Error( 1: ${this.state.email} )) ) and catches the thrown error and logs the response. The response shows the following line in index.android.bundle: new TypeError('Network request failed') .

Here are my nginx.error.logs:

I suspect there's some problem with my nginx configuration, but I don't know what it is.

I guess the production / debug android versions are different in someway, which would explain why the request works on my device when installed from android studio, but not from the play store. I don't know what that difference is.

Thanks.

Answer 1

This is the issue with signed Apk

Delete your android/build folder, ./gradle file

Generate a debug Apk

Then generate signed Apk

Answer 2

This might also be a proguard issue. It might work on 32 bit and fail on 64 bit or vice versa.

Answer 3

The problem was that Android now defaults to only allowing requests over HTTPS. My request was sent over HTTP. When this happens, the request fails silently.

To allow HTTP requests add the following to application your manifest ( AndroidManifest.xml ): android:usesCleartextTraffic="true"

Alternatively, you can make the request over HTTPS.
