1、問題描述

APP集成百度地圖后，開發(fā)者模式直接連接真機可以打開地圖，打包成apk后安裝，應用直接閃退

2、手機環(huán)境

驗證了3個環(huán)境
a、Android 6.0
b、Android 9.0
c、Android 8.1

3、問題排查過程

真機USB線連接

選擇Logcat，將日志級別選擇未error，日志太多，或者用自定義的過濾規(guī)則
先清除日志，后迅速點擊手機上的APP，觀察日志

發(fā)現(xiàn)需要監(jiān)控的APP報出異常信息，這個很關鍵，有異常就是有線索，couldn't find "libflutter.so"
這個時候問度娘就可以了

4、解決辦法

flutter build apk --target-platform=android-arm64

未明白具體的原因，臨時先解決了問題，馬克一下
