? 一、查找應用的主activity：
??pm list packages 發現所有的包
??dumpsys package + 包名： 獲取所有的包信息，可以所有關鍵詞MAIN來找主activity
??也可以通過下面命令找到所有activity，看下面大概率com.android.settings/.Settings為主activity
??dumpsys package com.android.settings | grep -i activity
2dee926 com.android.settings/.Settings$AdvancedConnectedDeviceActivity filter d570967 9a0114d com.android.settings/.Settings$AutomaticStorageManagerSettingsActivity filter cfb0402
37c7254 com.android.settings/.Settings$AppBubbleNotificationSettingsActivity filter 7ca75fd 47c7621 com.android.settings/.Settings$ApnEditorActivity filter 3828a46
47c7621 com.android.settings/.Settings$ApnEditorActivity filter 3828a46 c5ef02b com.android.settings/.Settings$PublicVolumeSettingsActivity filter ddb8c88
47c7621 com.android.settings/.Settings$ApnEditorActivity filter cda6407
二、例子8295:
?#:/ # pm list packages | grep -i setting ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??
package:com.android.providers.settings
package:com.android.settings# dumpsys package ?com.android.settings | grep -i activity ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??Activity Resolver Table:
? ? ? ? 6124ef5 com.android.settings/.Settings$ApnEditorActivity filter 58748a
? ? ? ? 5071fdf com.android.settings/.Settings$PublicVolumeSettingsActivity filter 538b42c
? ? ? ? 6124ef5 com.android.settings/.Settings$ApnEditorActivity filter 5e7dafb
?最后：
am start -n "com.android.settings/.Settings"
三、CloudCampus iperf華為測試工具，查找包名以及其主activity
??dumpsys package com.huawei.acceptance | grep -i activity
??am start -n com.huawei.acceptance/.PrivatePolicyMainActivity
am start -n com.nextdoordeveloper.miperf.miperf/.MainActivity
四、Wifi? P2P的包和啟動命令：
am start -n "github.leavesczy.wifip2p/.MainActivity"
am start -n "com.example.testsystem/.MainActivity"
