Flutter apk 在 android 设备中不起作用

Question

I try to generate apk file for my flutter app, I used flutter build apk --release command after flutter clean command. note that after used flutter build apk --release command I got this error:

Note: C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\android_intent-0.3.7+3\android\src\main\java\io\flutter\plugins\androidintent\MethodCallHandlerImpl.java uses unchecked or unsafe operations.

After that, I got the apk file from this path: C:\project_path\build\app\outputs\apk\release , but when I try to install this apk from the mobile I got this app not installed :

note: I'm tried more than one device with a different android version.

Please help me to solve my problem.

Seems to be warnings, not errors, thus the apk should be generated.

In any case, did you check the hardware architecture?

For example, try to specify the architecture for your smartphone:

flutter build apk --target-platform android-arm64

flutter build apk --target-platform android-arm ( <-- arm 32 bits)

etc...
