我在物理设备中测试我的应用
在调试运行
Console
$ adb push C:\Users\arjun\AndroidStudioProjects\Scol\app\build\outputs\apk\app-debug.apk /data/local/tmp/com.example.arjun.scol
$ adb shell pm install -r "/data/local/tmp/com.example.arjun.scol"
pkg: /data/local/tmp/com.example.arjun.scol
Success
$ adb shell am start -n "com.example.arjun.scol/com.example.arjun.scol.login.Login" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER -D

Disconnected from the target VM, address: 'localhost:8600', transport: 'socket'
我的应用因错误而崩溃,但debug console
中没有显示任何内容......这发生在updating android studio to 2.3
之后..
但是当我滚动浏览Android Monitor
时,我发现了错误消息

我也编辑过运行配置......但这并没有帮助...
我应该降级android studio吗?
答案 0 :(得分:4)
转到Run - &gt;编辑配置
第二个标签“杂项”
检查项目“自动显示logcat”
最好还检查项目“发布前清除日志”。
并查看Android Monitor logcat中的日志和崩溃
