Manual fix for "org.qtproject.qt5.android.network.QtNetwork" class not found

Re: Downloading data from Web URL (For Android)

in 5.15.2 its not working, there is a fix which is scheduled for 5.15.3 release. For now if you want to use QtNetwork in android you can apply this manual fix in your Qt android installation.

for arm64-v8a android target, edit the file
Qt\5.15.2\android\lib\Qt5Network_arm64-v8a-android-dependencies.xml
search and replace "QtAndroidBearer.jar" with "QtAndroidNetwork.jar" and rebuild your application.

repeat the steps for each of your android target (armeabi-v7a, x86,...)

Hello,

thanks for your solution.

For me it does not work. My Question is why not?
I use Qt5.15.2 & qbs1.17

My Qt5Network_arm64-v8a-android-dependencies.xml after modification:
<rules><dependencies><lib name="Qt5Network_arm64-v8a"><depends>
<jar bundling="1" file="jar/QtAndroidNetwork.jar" />
<lib file="plugins/bearer/libplugins_bearer_qandroidbearer_arm64-v8a.so" />
<bundled file="plugins/bearer" />
<permission name="android.permission.ACCESS_NETWORK_STATE" />
</depends></lib></dependencies></rules>

My output is:

You can help to resolve this please?

Thanks

@swk.'s fix worked for me. Also had to nuke entire build directory and re-build from scratch.

RubbieKelvin

i did the same... and got this error...

W System.err: java.lang.ClassNotFoundException: Didn't find class "org.qtproject.qt5.android.bearer.QtNetworkReceiver" on path: DexPathList[[],nativeLibraryDirectories=[/system/lib]]

Same here, after the workaround I get:
W System.err: java.lang.ClassNotFoundException: Didn't find class "org.qtproject.qt5.android.bearer.QtNetworkReceiver" on path: DexPathList[[],nativeLibraryDirectories=[/system/lib64]]

I'm using Qt 5.15.2 on Linux.

Instead of replace, just add <jar bundling="1" file="jar/QtAndroidNetwork.jar" /> to the xml file. So the final file should be:

<rules><dependencies><lib name="Qt5Network_arm64-v8a"><depends>
<jar bundling="1" file="jar/QtAndroidBearer.jar"  />
<jar bundling="1" file="jar/QtAndroidNetwork.jar"  />
<lib file="plugins/bearer/libplugins_bearer_qandroidbearer_arm64-v8a.so"  />
<bundled file="plugins/bearer" />
<permission name="android.permission.ACCESS_NETWORK_STATE" />
</depends></lib></dependencies></rules>

File to edit
Qt5Network_armeabi-v7a-android-dependencies.xml
Qt5Multimedia_arm64-v8a-android-dependencies.xml

@piervalli why arm64-v8a for Qt5Multimedia and armeabi-v7a for Qt5Network?
You probably meant both architectures for Qt5Network...right?

piervalli

@GBergamo Yes, I create two apk, arm7 and arm8.
