Even granting WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions, the application closes unexpectedly or does not record anything.

[hardx4]

I cloned the repository and did some tests with writing on nodejs, without success. I don't know why, but even with permissions granted the application cannot write on the system. The same main.js works perfectly if compiled with the help of androidjs-builder on ubuntu, but the application generated on Android Studio on windows through the source of this repository does not have the same effect.

May be you have done something wrong because we are also using the same source to test our API's while building and it works.

did you put the node binaries at correct place ?

[Chhekur]

if the application is crashes then there must be some exception occurring, so you should look into the log for when and what exception is occurring that causes crashing ; )

Feel free to ask in case of any problem ; )

The "include" folder was placed in the "libnode" folder, as were the ".so" binaries in the "bin" folder. A strange thing that I noticed, was that even if you leave a single permission in "AndroidManifest.xml", for example: "android.permission.INTERNET". The app asks for "android.permission.CALL_PHONE" permission.

I did a lot of testing, i test just cloning the repository and putting the node and include binaries. I don't know what can be wrong. I checked everything to find out why the app was asking for "android.permission.CALL_PHONE", even without being asked for in the manifest.

Still I couldn't write to storage.

The Android Studio debug doesn't tell me anything when the app closes unexpectedly. All I know is that if I compile using androidjs-builder, the same assets work, and I can write to storage. But this gradle webview repository has not worked.

I'm using an Android Studio version 3.6.2 installed on Windows 10.

Could you help me in solving this?

Can you provide me the logcat of your app ? this will help me to find out why the app is getting crashed ; )

[hardx4]

I'll check where to find this, but this is my assets in the main directory:

Debug log in Android Studio on the emulated device.

Java Printing console.pdf

When I get home, I send a debug log from a physical device.

Note that in my androidManifest.xml there is no permission for "CALL_PHONE", even so, the log presents a request.

Look at the logs it is generating error no such file or directory that's why app is getting crashed ; )

Let me know in case of any other doubt ; )

[hardx4]

But the app opens, works the way it should, but stops unexpectedly, this error "no such file or directory" also occurs with the apk generated with androidjs-builder, however it does not prevent it from working. Why does the app ask for "CALL_PHONE" permission even without the "android.permission.CALL_PHONE" declared in the manifest?

The apk generated with androidjs-builder does not crash, it starts and in the process the data it can write to storage, but the same view in the gradle project does not work, this is my dilemma.

When requesting permissions on the gradle project in manifest file: <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

In the apk generated by androidjs-builder a single confirmation box appears. But in the apk generated by the gradle project, two are displayed, one to allow CALL_PHONE and the other WRITE_EXTERNAL_STORAGE, the one by CALL_PHONE should not appear, but inexplicably it does.

My Manifest permissions is: <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

[hardx4]

The problem of the app crashing I solved, i copied the files libnode.so and the node source from my ubuntu VPS. After many tests I realized that the problem was not the permissions, so I only had one last variable that was the version of the node. I just had to copy the necessary files to the libnode folder of the Android Studio core-webview, I was a little afraid that it wouldn't work, but I was successful. The node source, copied from one of the versions installed on my nvm, version 13.6.0 and the libnode.so for the architectures copied from the .cache folder of androidjs-sdk.

The app is still asking permission for CALL_PHONE even without it being requested in the manifest, I don't know what it might be, but I believe there is a way to resolve it by removing the possibility of adding to the array of permission strings at checkAndAskForPermissionsHelper
