Android.bat的运行选项

"list ":         
"list avd":      
"list target":   
"create avd":    
"move avd":      
"delete avd":    
"update avd":    
"create project":
"update project":
"update adb":   

 

    adb.exe的运行选项

    

Android Debug Bridge

Android的调试桥，运行该命令时必须先启动模拟器；然后才可以在模拟器上运行linux命令或安装卸载apk软件。

 

  adb devices                  - list all connected devices

 

device commands:
  adb push <local> <remote>    - copy file/dir to device
  adb pull <remote> <local>    - copy file/dir from device
  adb sync [ <directory> ]     - copy host->device only if changed
                                 (see 'adb help all')
  adb shell                    - run remote shell interactively
  adb shell <command>          - run remote shell command
  adb emu <command>            - run emulator console command
  adb logcat [ <filter-spec> ] - View device log
  adb forward <local> <remote> - forward socket connections
                                 forward specs are one of:
                                   tcp:<port>
                                   localabstract:<unix domain socket name>
                                   localreserved:<unix domain socket name>
                                   localfilesystem:<unix domain socket name>
                                   dev:<character device name>
                                   jdwp:<process pid> (remote only)
  adb jdwp                     - list PIDs of processes hosting a JDWP transport

 

  adb install [-l] [-r] <file> - push this package file to the device and install it

 

  adb uninstall [-k] <package> - remove this app package from the device

    -- 这个package名称是在AndroidManifest.xml文件中定义的
 
scripting:
  adb wait-for-device          - block until device is online
  adb start-server             - ensure that there is a server running
  adb kill-server              - kill the server if it is running
  adb get-state                - prints: offline | bootloader | device
  adb get-serialno             - prints: <serial-number>
  adb status-window            - continuously print device status for a specified device
  adb remount                  - remounts the /system partition on the device read-write
  adb root                     - restarts adb with root permissions

 

        apk文件在模拟器上的安装和卸载

    

安装

    D:\android\tools＞adb install c:\NetScramble_1.1.apk

卸载

    D:\android\tools＞adb uninstall bison.sample.helloworld

或者

    D:\android\tools＞adb shell rm data/app/NetScramble_1.1.apk

使用这种办法，可以提高开发调试的速度。

 

    AndroidManifest.xml文件详解

    

Android全局配置文件AndroidManifest.xml
在最外层包含了包名如 package="cn.android123.demo" 、软件的版本号    android:versionCode="1" 以及   android:versionName="1.0" ，里面一层的application分支中将可能包含Android程序的四种对象 Activity、Service、Content Provider以及Receiver。我们每添加上面四个类型中的任一新对象都需要在androidmanifest.xml文件中添加相应节点。

 

其中Activity的属性常用的可能为android:name和android:label但我们需要了解所有的属性以帮助解决复杂的问题，完整的如下: 
          android:allowTaskReparenting=["true" | "false"]
          android:alwaysRetainTaskState=["true" | "false"]
          android:clearTaskOnLaunch=["true"" | "false"]
          android:configChanges=[one or more of: "mcc" "mnc" "locale"
                                 "touchscreen" "keyboard" "keyboardHidden"
                                 "navigation" "orientation" "fontScale"]
          android:enabled=["true" | "false"]
          android:excludeFromRecents=["true" | "false"]
          android:exported=["true" | "false"]
          android:finishOnTaskLaunch=["true" | "false"]
          android:icon="drawable resource"
          android:label="string resource"
          android:launchMode=["multiple" | "singleTop" |
                              "singleTask" | "singleInstance"]
          android:multiprocess=["true" | "false"]
          android:name="string"
          android:noHistory=["true" | "false"] 
          android:permission="string"
          android:process="string"
          android:screenOrientation=["unspecified" | "user" | "behind" |
                                     "landscape" | "portrait" |
                                     "sensor" | "nonsensor"]
          android:stateNotNeeded=["true" | "false"]
          android:taskAffinity="string"
          android:theme="resource or theme"
          android:windowSoftInputMode=[one or more of: "stateUnspecified"
                                       "stateUnchanged" "stateHidden"
                                       "stateAlwaysHidden" "stateVisible"
                                       "stateAlwaysVisible" "adjustUnspecified"
                                       "adjustResize" "adjustPan"] >  

 

    基础知识

    ·手机屏幕参数的了解
  市面上常规的机型使用了320x240的 QVGA。N73就是这种分辨率。
  比如目前使用的是480x320的 HVGA
  800x480的   WVGA
