Android : What permissions are required to use the ti.barcode module?

[nicolomonili]

On iOS i have no problem, i only ask the permission for the camera

if (Ti.Media.hasCameraPermissions()) {
    openQrcode();
} else {
    Ti.Media.requestCameraPermissions(function(e) {
        if (e.success) {
            openQrcode();
        } else {

            var tempmessage = "Hai negato l'accesso alla fotocamera del dispositivo inibendone la possibilità di scansionare i QR code.\n\n";
            if (isAndroid) {
                tempmessage += "Naviga in Impostazioni / App / " + Ti.App.name + " / Autorizzazioni e consenti l'accesso alla fotocamera.";
            } else {
                tempmessage += "Naviga in Impostazioni / Privacy / Fotocamera / " + Ti.App.name + " e consenti l'accesso alla fotocamera.";
            }

            var alertDialog = Ti.UI.createAlertDialog({
                title: "Attenzione",
                message: tempmessage,
                buttonNames: ["Ok"]
            });
            alertDialog.show();

        }
    });
}

function openQrcode() {
    Barcode.capture({
        animate: false,
        overlay: overlayQrcode,
        showCancel: false,
        showRectangle: true,
        keepOpen: false,
        acceptedFormats: [
            Barcode.FORMAT_QR_CODE
        ]
    });
}       

But now on Android i think i have some problems with the permission... For Android i use the same code above, plus this on the tiapp.xml

<android xmlns:android="http://schemas.android.com/apk/res/android">
        <manifest>
            <application android:theme="@style/Theme.AppCompat.Translucent.NoTitleBar.Fullscreen"/>
            <application android:debuggable="false"/>
            <uses-sdk android:minSdkVersion="16" android:targetSdkVersion="23"/>
            <uses-permission android:name="android.permission.CAMERA"/>  
        </manifest>
</android>   

On Android , when i have to open the camera, two permission requests are displayed

After the permissions are accepted, the function openQrcode() is called, and the app crashes.

check this example https://github.com/appcelerator-modules/ti.barcode/issues/59#issuecomment-403747604 You only need the normal Android camera permissions, like you would use to display and use the normal camera in Titanium. So you can check the official documentation too.

If you check your app permission on your phone it should allow storage and camera in order to work. Do you have any error message in the log?

[nicolomonili]

This is the actual permissions of the app

Unfortunately there is no log on the console

[m1ga]

check adb logcat there should be a lot of output and stop it right after the crash to see if you can spot something. That would help alot. Permissions should be fine.

[m1ga]

is this on device or emulator (I see genymotion in the log)? But interesting error, I'll check that later

[nicolomonili]

Emulator, Genymotion yes

---

I tried to remove only the Barcode.capture from my code

Barcode.capture({
    animate: true,
    overlay: overlayQrcode,
    showCancel: false,
    showRectangle: false,
    keepOpen: true,
    //acceptedFormats: [
    //   Barcode.FORMAT_QR_CODE
    //]
});

and i replaced it with the code to open the camera

Ti.Media.showCamera({
    success: function(e) {
        //callback(null, e);
    },
    cancel: function(e) {
        //callback(e, null);
    },
    error: function(e) {
        //callback(e, null);
    },
    saveToPhotoGallery: true,
    // save our media to the gallery
    mediaTypes: [Ti.Media.MEDIA_TYPE_PHOTO]
});       

the app don't crash, and camera opens correctly

Something is wrong with your overlay:

Unable to start activity ComponentInfo{com.-.-/com.google.zxing.client.android.CaptureActivity}: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

Please refer to general help via Slack or StackOverflow. This issue tracker is focussed on module bugs, which this one isn't.

[nicolomonili]

Incredible ... I found what caused the crash ... it's the property borderColor of the view overlayQrcode...

On iOS the property borderColor is not a problem, on Android cause the crash
