addAndroidDownloads can't recognize Android APK file

[siyuan]

I download an APK file using addAndroidDownloads. I click the file but can't open. This is my config.
RNFetchBlob.config({
addAndroidDownloads : {
useDownloadManager : true,
title : 'some apk',
description : 'apk install file',
mime : 'application/vnd.android.package-archive',
mediaScannable : true,
notification : true,
}
})
.fetch('GET', 'http://xxxxxxx/yyy.apk')

How to let Downloads know yyy.apk is an APK file?

[wkh237]

@siyuan , thank you for reporting this problem, I've never tried download an APK using DownloadManager, I'll do some tests about this issue.

[wkh237]

@siyuan , according to this post and this StackOverflow, perhaps you can not install APK in Downloads App due to some security issue, but it is possible to do it using an intent.

However user still have to change their settings, otherwise it will prompt something like this

I've added a new API for Android which can send an intent that opens a file in an activity correspond to its MIME type (see test cases for its usage). This API will launch in 0.9.0

@wkh237 Thank you very much for your help. I clone react-native-fetch-blob to node_modules of my project, and checkout to branch 0.9.0. I got this error when compiling:

JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug...

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':app'.

  Cannot evaluate module react-native-fetch-blob : Configuration with name 'default' not found.

Is there any new configuration for version 0.9.0?
Thank you.

@siyuan , the error message usually means android/settings.gradle contains wrong project path. Since the git repository contains the whole development environment, I suppose you should copy files in src folder to your node_modules and rename the folder to react-native-fetch-blob instead of copy the whole folder 😏 src is the folder which we publish as npm package.

Alternatively, you can install beta version from npm

$ npm install --save react-native-fetch-blob@beta

Which will install beta release

Beta README.md.

[siyuan]

"$ npm install --save react-native-fetch-blob@beta", this method doesn't work. the same as before. It seems that Downloads app can't recognize the new downloaded app.

[siyuan]

"copy src to node_modules and rename the folder to react-native-fetch-blob" doesn't work either. I use hardware Android 6.0, Android 6.0 simulator and Android 5.1 simulator do the test. None of them work.

[wkh237]

@siyuan , The error message means the path it points to does not contains an Android project. did you check android/settings.gradle if there contains a correct path to the android project of react-native-fetch-blob?

rootProject.name = 'RNFetchBlobTest'

include ':app'
+include ':react-native-fetch-blob'                                                                                                                                                   
+project(':react-native-fetch-blob').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-fetch-blob/android'')                                                                

In this case, there should be an Android project in node_modules/react-native-fetch-blob/android/, also check if the path string contains extra space that causes the error (See #62)

As for the installation problem, after upgrade to 0.9.0-beta.x, you should use RNFetchBlob.android.actionViewIntent(path, mime) install the APK, simply click the APK in Downloads app will not work since is not supported.

[siyuan]

Thank you for your help.
I can install react-native-fetch-blob@beta and compile successfully, but cannot install the APP. This is my code:

upgradeApp()
  {
    RNFetchBlob.config({
      addAndroidDownloads : {
        useDownloadManager : true,
        mime : 'application/vnd.android.package-archive',
        mediaScannable : true,
        notification : true,
      }
    })
    .fetch('GET', 'http://x.x.x.x/doc/abc.apk')
    .then((res) => {
      console.log('save to ' + res.path())
      let sendIntent = RNFetchBlob.android.actionViewIntent
      return sendIntent(res.path(), 'application/vnd.android.package-archive')
    })
    .then(() => {
      done()
    })    
  }

I found the console output is "save to null". I think this is the problem. Why the path is null?
I appreciate your help. Thank you.

Hi, @siyuan , does this happens on Android 6.0 only or it also happens on 5.x ?

[siyuan]

Hi, @wkh237
Android 6.0 and 5.1 have this problem with react-native-fetch-blob v0.9 beta.
By the way, react-native-fetch-blob v0.8.1's res.path() is correct.

[wkh237]

@siyuan , thanks for your information. I think I know where the problem is, I'll publish a test version later !

[wkh237]

@siyuan , please try 0.9.0-beta.5 and see if the problem got solved

$npm install --save react-native-fetch-blob@beta

Thank you 😄

[siyuan]

@wkh237 0.9.0-beta.5's res.path() is null. Tested on 6.0 and 6.1.

[wkh237]

@siyuan , Since I don't have 6.0 + devices and I can't reproduce the problem on emulator, I'd like to know more information if you can give me a hand !

• content of res.data
• the res.type

It would be nice if you have an Android IDE (Android Studio), you can set break points at the following lines

/react-native-fetch-blob/blob/0.9.0-beta.5/src/android/src/main/java/com/RNFetchBlob/RNFetchBlobReq.java#L573

/react-native-fetch-blob/blob/0.9.0-beta.5/src/android/src/main/java/com/RNFetchBlob/RNFetchBlobReq.java#L585

/react-native-fetch-blob/blob/0.9.0-beta.5/src/android/src/main/java/com/RNFetchBlob/RNFetchBlobReq.java#L588

/react-native-fetch-blob/blob/0.9.0-beta.5/src/android/src/main/java/com/RNFetchBlob/RNFetchBlobReq.java#L592

see if they're executed and the value of filePath

[siyuan]

@wkh237
res.data /data/user/0/com.android.providers.downloads/cache/abc.apk
res.type undefined

I will study how to set breakpoint in Android Studio.
Thank you.

[wkh237]

Thank you ! @siyuan , this would be helpful, you can also use res.data as an alternative of res.path()

[siyuan]

@wkh237 use res.data still cannot install by sendIntent. I have enabled "Unknown sources, Allow installation of apps from unknown sources"
I'm afraid sendIntent have problem.

[wkh237]

@siyuan , does it help if you reinstall the package ?

$ rnpm uninstall react-native-fetch-blob
$ npm install --save react-native-fetch-blob@beta
$ rnpm link

then recompile the project

[siyuan]

@wkh237 I found my issue happened on
"react": "15.2.0",
"react-native": "^0.28.0",

When I create a new project with 'react-native init', sendIntent works fine ("react": "15.2.1", "react-native": "^0.31.0"). res.path() has right value.

Do you have plan to support old react-native version?

[wkh237]

@siyuan , thanks for the information. I'll do some test on that version and see if I can fix it. However you can also upgrade you application if possible.

[wkh237]

@siyuan , it turns out that the API works properly on 0.24~0.31 environments, could you try removing the package from node_modules and reinstall it ? I think the problem might due to the inconsistency between js and native module version in your environment ?

[siyuan]

@wkh237
I completely reinstalled my APP. react-native-fetch-blob's intent works fine with "react-native 0.28.0". Thank you very much. I appreciate your help.

[wkh237]

@siyuan , great 👍 Please feel free to ask any question anytime.
