Description
With Qt 5.14.0-beta3 I cannot package previously working projects anymore for Android (any arch).
The manifest has metadata tags in it as seen at e.g. this project: https://github.com/qt-labs/weather-app/blob/master/android/AndroidManifest.xml#L16 , which is also used in all of my existing Qt projects for Android.
<meta-data android:resource="@array/bundled_in_lib" android:name="android.app.bundled_in_lib_resource_id"/> <meta-data android:resource="@array/bundled_in_assets" android:name="android.app.bundled_in_assets_resource_id"/>
I can compile the native C++/Qt part, but when reaching the point where gradle/java starts (androiddeployqt), I find these errors:
/home/gregor/aaDev/me/projects/appdemos/messaging/build-android/build/intermediates/merged_manifests/debug/processDebugManifest/merged/AndroidManifest.xml:87: AAPT: error: resource array/bundled_in_assets (aka net.me.demos.apps.messaging:array/bundled_in_assets) not found. <meta-data android:resource="@array/bundled_in_assets" android:name="android.app.bundled_in_assets_resource_id"/> AndroidManifest.xml:84: AAPT: error: resource array/bundled_in_lib (aka net.me.demos.apps.messaging:array/bundled_in_lib) not found.
So temporary removed those two lines so build can go on.
When inspecting the generated R.java file, indeed those two arrays are missing now, but were always present in previous Qt versions.
public static final class array { public static final int bundled_libs=0x7f020000; public static final int load_local_libs=0x7f020001; public static final int qt_libs=0x7f020002; public static final int qt_sources=0x7f020003; }
------------------------------------------------------------
Also found another meta data field is now required for my app to start with Qt 5.14, otherwise Qt fails to load files at activity start and white screen appears (with crash info in adb).
<meta-data android:name="android.app.load_local_libs_resource_id" android:resource="@array/load_local_libs"/>

I found the workaround by looking at line 423 at QtLoader.java
int resourceId = m_contextInfo.metaData.getInt("android.app.load_local_libs_resource_id");
for (String libs : prefferedAbiLibs(m_context.getResources().getStringArray(resourceId))) {

Would be very nice if the first issue can be resolved, so existing projects can keep said two metadata fields even if not used anymore by Qt.
Suggestion: Generate empty arrays (with same ID's as before).
Empty but existing arrays -> gradle won't fail at AndroidManifest steps for existing projects. Currently a app that worked till Qt 5.13 cannot be packaged/run with Qt 5.14 and when making change for Qt 5.14 again cannot run at Qt 5.13 because missing two fields.
Unsure about the second part, let me know if should be splitted off.
Both may be related to Qt Bug and it's related changes: https://bugreports.qt.io/browse/QTBUG-80178
Please let me know if there's something unclear, more info required, or anything!
