有以下四种方法可以查看apk的包名，之后有别的方法，会接着更新文档的。
1. 安装APK包名查看器;
2. 源码AndroidManifest.xml中查看package包名;
3. 利用"*\adt-bundle-windows-x86-20130917\sdk\tools\hierarchyviewer.bat"获取当前活动package的包名，同时可以获取控件的坐标和ID;
4. 利用aapt查看包名: tools或者platform tools或者sdk/build-tools/aapt.exe(进入cmd)
aapt dump badging *.apk
由于输出信息比较多，容易覆盖包名，建议把info输出到txt文件中：
aapt dump badging *.apk >info.txt
输出如下：
Package Groups (1)
Package Group 0 id=127 packageCount=1 name=com.chartcross.gpstest
Package 0 id=127 name=com.chartcross.gpstest typeCount=11
type 0 configCount=1 entryCount=32
spec resource 0x7f010000 com.chartcross.gpstest:attr/adSize: flags=0x00000000
spec resource 0x7f010001 com.chartcross.gpstest:attr/adSizes: flags=0x00000000
spec resource 0x7f010002 com.chartcross.gpstest:attr/adUnitId: flags=0x00000000
5. adb logcat抓取当前运行的apk的包名：ActivityManager(数字)：Displayed 包名/类名：+ **ms
adb logcat > log.txt (从最后log开始找或者搜索关键字)
输出如下：
I/ActivityManager( 506): Displayed com.android.gallery3d/.app.GalleryActivity: +1s89ms
I/ActivityManager( 506): Process com.android.music (pid 1009) has died
W/BlobCache( 1520): cannot read header
D/ ( 136): RPCSendMsgToClient: remote_app_id = 0, context_id = 0
D/ ( 162): AppRecvFromRPCIFTask: recieved_bytes = 54
D/ ( 162): IPC ReadCB: RSP/IND idx(91)
D/ ( 156): AppRecvFromRPCIFTask: recieved_bytes = 54
又或者以关键字"android.intent.category.LAUNCHER"搜索：
W/RenderThread( 1030): type=1400 audit(0.0:86): avc: denied { read write } for path="/dev/mali" dev="tmpfs" ino=11374 scontext=u:r:untrusted_app:s0 tcontext=u:object_r:device:s0 tclass=chr_file
I/ActivityManager( 506): START u0 {act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.android.gallery3d/.app.GalleryActivity (has extras)} from uid 10008 on display 0
D/MSM ( 134): event = change@/devices/rk818.196/rk818-battery/power_supply/BATTERY
D/MSM ( 134): event = !modem event ignore
D/MSM ( 134): --> wait for event
