android应用学习---2.eclipse与ndk adb等工具的使用

1. adb
a. adb devices 出现 no permisions的解决方法

cong@ubuntu:~$ which adb
/opt/android/adt-bundle-linux-x86_64-20131030/sdk/platform-tools/adb
cong@ubuntu:~$ sudo /opt/android/adt-bundle-linux-x86_64-20131030/sdk/platform-tools/adb kill-server
cong@ubuntu:~$ sudo /opt/android/adt-bundle-linux-x86_64-20131030/sdk/platform-tools/adb start-server

注意一定要用root
b. adb devices为空的解决方法

a. 建51-android.rules文件
cong@ubuntu:/tmp$ cat /etc/udev/rules.d/51-android.rules
SUBSYSTEM=="usb", SYSFS{idVendor}=="0e8d", MODE="0666"
SUBSYSTEM=="usb", SYSFS{idVendor}=="2207", MODE="0666"

b. 将pid写到adb_usb.ini中
cong@ubuntu:/tmp$ vi /home/cong/.android/adb_usb.ini
cong@ubuntu:/tmp$ cat /home/cong/.android/adb_usb.ini
0x2207

c. adb 通过wifi连接

a. 确保手机能与电脑Ping通
b. 手机可以执行su
c. 手机己经装上 “安卓终端模拟器”

然后打开 安卓终端模拟器，输入以下命令(红色标出)：
#!/system/bin/sh
#设置监听的端口，端口可以自定义，如5554，5555是默认的
setprop service.adb.tcp.port 5555
#关闭adbd
stop adbd
#重新启动adbd
start adbd

2. ndk
1. Android NDK: Host 'awk' tool is outdated. Please define HOST_AWK to point to Gawk or Nawk !

   解决方法:  Navigate to ../android-ndk-r7/prebuilt/linux-x86/bin
                  Rename the file awk to awk_           
   

3. eclipse

a. Dex Loader] Unable to execute dex: java.nio.BufferOverflowException. Check the Eclipse log for stack trace.
Conversion to Dalvik format failed: Unable to execute dex: java.nio.BufferOverflowException. Check the Eclipse log for stack trace.
解决方法: right click your project > android tools > android support library
参考文章: http://stackoverflow.com/questions/19727915/android-dex-gives-a-bufferoverflowexception
b. 显示行号
"window" ->; "preference" ->; "java" - >; "editor" ->; "show line numbers"
c. 安装sdk
打开eclipse所指定的sdk_location:
    windows-> preference -> android --> SDK location
把下载的东东放在 sdk/platform目录中

4.am
    a. am 启动一个activity
       am start -n packagename/.activityname  ;;注意activityname前面有个点
        例: adb shell am start -n com.touchtest/.MainActivity 
5. monkey
adb shell monkey -v -p com.writetest  --pct-touch 100 11
-v 显示信息
-p 指定package_name
--pct-touch 指定touch的百分比,这儿是100%
11是发送的次数cnt
上述命令是向 com.writetest这个包发送touch 11次
