Android auto update

You need to process the URI through FileProvider. It's an awfully awkward and tedious thing, but Android requires it since version 6 IIRC.
Basically you need to:
- Add file provider to
res/xml/fileprovider.xml. Example contents:
<?xml version="1.0" encoding="utf-8"?> <paths> <cache-path name="exports" path="." /> <!--Uncomment below to share the entire application specific directory --> <!--<external-path name="all_dirs" path="."/>--> </paths>- Register that provider in your manifest:
<provider android:name="android.support.v4.content.FileProvider" android:authorities="your.application.domain.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/fileprovider" /> </provider>- In every place in Java you need to use the file provider to "access" that file, instead of regular File/ Intent. I don't have Qt code for this, only some Java (and written for different purpose so it might be incorrect for your case):
import android.support.v4.content.FileProvider; // ... Uri providerUri = FileProvider.getUriForFile( this, "your.application.domain.fileprovider", fileName);You probably need to do the opposite (get file for URI). Not sure. I wrote this ages ago and APIs in Android keep changing all the time :-(
- You may also need to add the v4 compat library in gradle config, I'm not sure. It could be something like this:
dependencies { implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar']) compile 'com.android.support:support-v4:23.+' }I hope this will help you at least a bit. And sorry for not being more specific, I'm not sure about any of it :D This won't be easy, good luck!

Thanks for the reply, it's a little complicated for me, I absolutely don't understand the java, maybe I'll try it later.@Kutyus my share example has implemented Android FileProvider https://github.com/ekke/ekkesSHAREexample

Great example.
Got it to work immediately with Qt5.12.7, but failure with Qt5.14.2.
Are you interested to get a bug report? And when where?Vote the answer(s) that helped you to solve your issue(s)

unfortunately most of my examples are 3 years or more old and last 2 years I had to develop so many mobile business apps, so I didn't found enough spare time
the good thing: starting with Qt 5.15 I'll rework all my examples and blogs to get mobile apps ready for Qt6 / strict QML 3. will reduce work for customers next months and concentrate on 5.15 / 6.0. with some luck all of this will finally end in a book (fingers crossed)

Thanks. Report created
@koahnig thx reporting. will test when I've done my switch from 5.13 --> 5.15

Hi!
I made the settings, but on this line, there is always an error:QAndroidJniObject uri = QAndroidJniObject::callStaticObjectMethod("android.support.v4.content.FileProvider", "FileProvider.getUriForFile", "(Landroid/content/Context;Ljava/lang/String;Ljava.io.File;)Landroid/net/Uri;", activity.object(), authority.object(), file.object());System.err: java.lang.NoSuchMethodError: no static method "Landroid/support/v4/content/FileProvider;.FileProvider.getUriForFile(Landroid/content/Context;Ljava/lang/String;Ljava.io.File;)Landroid/net/Uri;"I also tried the getUriForFile method without the FileProvider prefix, the same error anyway.

I don't know JNI enough to answer, for me it's always a bunch of trial and error to get it to work :D

@Kutyus Your JNI call is not correct, you pass wrong method name!
It should be:QAndroidJniObject uri = QAndroidJniObject::callStaticObjectMethod( "android.support.v4.content.FileProvider", "getUriForFile", // only the function name!! "(Landroid/content/Context;Ljava/lang/String;Ljava.io.File;)Landroid/net/Uri;", activity.object(), authority.object(), file.object());It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth.

I tried anyway. The error in the second parameter was slashes instead of periods in the java.io.File section.
If I log out after the call, I get an error that there is no activity handling the intent, if I don't log out immediately, there is no error, but nothing happens. I don't know where the error might be. -
