适用于 Android 的 Qt QML 错误

Question

Guys I'm writing an Instant Messaging app with Qt 5.14, and I am trying to deploy it for Android devices

I've installed these:

• OpenJDK 8 (amd64)
• NDK r20b
• Qt Creator 4.11.0
• Qt 5.14 (for Android ARM64-v8a device)

I can build the app correctly, but when I run it from the phone, there's only a white screen

From Qt Creator I can see this application output

I nixsoftware.as: Late-enabling -Xcheck:jni
I Perf    : Connecting to perf service.
E nixsoftware.as: Invalid ID 0x00000000.

I noticed the similar behaviour after upgrading to Qt 5.14. Searching the Qt bugreports lead me to QTBUG-80266 . As suggested in comments, I re-created the AndroidManifest.xml and added back my local changes, my app now executes. I hope it helps.
