運行android-cmd.bat,使用cd命令切換到samples/hello-jni目錄下,

運行android update project -p . -s,會生成build.xml文件,用于ant命令,要注意的是,編譯的時候會發生錯誤,提示:

Error: The project either has no target set or the target is invalid.
Please provide a --target to the 'android.bat update' command.

這個時候,可以使用android list targets命令來查看當前系統中的android模擬器,我有兩個,如下:

I:\android\android-ndk-r7c\samples\native-activity>android.bat list targets
Available Android targets:
----------
id: 1 or "android-8"
???? Name: Android 2.2
???? Type: Platform
???? API level: 8
???? Revision: 1
???? Skins: HVGA, QVGA, WQVGA400, WQVGA432, WVGA800 (default), WVGA854
???? ABIs : armeabi
----------
id: 2 or "android-10"
???? Name: Android 2.3.3
???? Type: Platform
???? API level: 10
???? Revision: 2
???? Skins: HVGA, QVGA, WQVGA400, WQVGA432, WVGA800 (default), WVGA854
???? ABIs : armeabi

如果沒有的話,需要使用SDK的AVD Manager來創建一個就可以了.而我使用的是android 2.3.3的模擬器,所以我的編譯命令是:

I:\android\android-ndk-r7c\samples\native-activity>android update project -p . -
t android-10 -s
Updated and renamed default.properties to project.properties
Updated local.properties
No project name specified, using Activity name 'NativeActivity'.
If you wish to change it, edit the first line of build.xml.
Added file I:\android\android-ndk-r7c\samples\native-activity\build.xml
Added file I:\android\android-ndk-r7c\samples\native-activity\proguard.cfg

從上面看出,已經生成了build.xml文件了.

運行ant debug命令,輸出如下:

I:\android\android-ndk-r7c\samples\hello-jni>ant debug
Buildfile: I:\android\android-ndk-r7c\samples\hello-jni\build.xml

BUILD SUCCESSFUL

從上面,可以看出,生成了HelloJni-debug.apk,那么使用adb命令安裝到當前的虛擬機上就可以了.

運行adb install bin/HelloJni-debug.apk命令,如果出現:error: device not found,說明你的android模擬器尚未start.

運行后,出現如下提示:
