開發階段可能需要一些簡單的測試程式（執行檔) , 來進行一些小功能測試 , 所以下一個階段 , 移植一個小執行檔進入 TI BSP 吧 !!
之前我們有一個 lcd-test 的程式 , 由 console press "Enter" key , 會使用 mmap 方式填寫固定 pattern 到 fb0 內. 就先移植這個吧 !!
同樣的使用自己的 makefile 方式 .
首先開一的資料夾 ( android 的 main.mk 會自己尋找 ) , 可以有兩層 , 我的方式如下:
rowboat-android/test_apps/test/lcd-test & rowboat-android/test_apps/test/lcd-test/lcd-test-0.0.1
在 lcd-test 資料夾下放入 Android.mk file , 內容如下:

主要將一些 ldflags , cflags export 到 下一層 Makefile 使用 , 其中 EXE_EXT_FILES 是因為執行檔 , 會需要這兩個 .o file , 並且很奇怪需要放在 同一個目錄下 , 我試過使用 --sysroot=<path> 的方式 , 也是不行 , 所以只好 copy 過去 make 完畢後 delete 掉.
接著在 ./lcd-test-0.0.1/ 下建立 Makefile , 這個 makefile 就是自己的方式.內容如下:

##==========================================
build 完畢後 ,利用 lrz 傳到 EVB 上的 /system/bin/ 下 . 執行看看 !!
成功....... ^^ , 不過會被原本 的畫面 re-flash 掉 , 所以建議找畫面更新率最低的頁面測試 , 或是使用 stop command 讓 java machine 暫停 , 在利用 console 執行測試程式.
Android 的 fb0 位置和一般linux 不同 , 移動到 /dev/graphics/fb0 位置.

Add Busybox into TI Android BSP
開發階段 , 很多東西都在 console 下進行一些 debug 的動作 , 有些小修改 , 卻沒有 vim 可以用 , 加上有些常用的 busybox command 都沒有 , 真的有點不方便 !!
之前有 lrz/lsz 的經驗 , 這次一樣如法泡製 , 將 busybox 移植到 TI 的 BSP 中 !!
一樣借用 linaro 這個組織的東西 網址 :

一樣修改一下 Android.mk file (格式和 debug message 修改 ) .

Add JNI demo code ( java + C )
Pure Java 完成了 , 改換 JNI 方式吧 !! 將 a + b 的動作 用 C library 來完成 .
一樣使用之前 pure java 的 code , 如下列修改方式.
private OnClickListener mAddListener = new OnClickListener()
{
@Override
public void onClick(View view)
{
int a = Integer.parseInt(mEditText1.getText().toString());
int b = Integer.parseInt(mEditText2.getText().toString());
- int result = a+b;
+ int result = addJNI(a, b);
mButton.setText(String.valueOf("A+B=" + result));
}
};
並且在 .java 中加入 :
public native int addJNI(int a, int b);
static
{
System.loadLibrary("androint-jni");
}
## 注意 library 的名稱為 libandroint-jni.so , java 會自動將 lib prefix 補上去 , 所以JNI 產生的 so file , 要注意 , 也需要 lib 這個 perfix.
接著先 產生 .class file , 在由 .class file 產生 .h , 然後 .c file include 這個 .h 並且完成 function 的功能.
產生 .class 的方式可以用下列的command :
javac -d ./ -cp /${HOME}/android-sdk-linux/platforms/android-15/android.jar src/com/eps/william/androint/AndroIntActivity.java <source top>/out/target/common/R/com/eps/william/androint/R.java
接著用 javah 來產生 .h file , command 如下:
javah -jni -classpath ../bin com.eps.william.androint.AndroIntActivity
經過測試 ,沒有問題 , 只是..... 一切都不自動 , 需要手動產生, 並且還要先編譯 java 程式 , 然後手動產生 .h file , 然後 修正 .c file , 最後在 Android.mk 中加入 .so 的 make 部份 . 一點都不優......
經過幾天的 study , 修改了一下 Android.mk 內容 , 讓整個 make 過程中自動產生 .h 然後接著 compile .c file 產生 .so ...... , 修改後的 Android.mk 如下:

一樣使用之前 pure java 的 code , 如下列修改方式.
private OnClickListener mAddListener = new OnClickListener()
{
@Override
public void onClick(View view)
{
int a = Integer.parseInt(mEditText1.getText().toString());
int b = Integer.parseInt(mEditText2.getText().toString());
- int result = a+b;
+ int result = addJNI(a, b);
mButton.setText(String.valueOf("A+B=" + result));
}
};
並且在 .java 中加入 :
public native int addJNI(int a, int b);
static
{
System.loadLibrary("androint-jni");
}
## 注意 library 的名稱為 libandroint-jni.so , java 會自動將 lib prefix 補上去 , 所以JNI 產生的 so file , 要注意 , 也需要 lib 這個 perfix.
接著先 產生 .class file , 在由 .class file 產生 .h , 然後 .c file include 這個 .h 並且完成 function 的功能.
產生 .class 的方式可以用下列的command :
javac -d ./ -cp /${HOME}/android-sdk-linux/platforms/android-15/android.jar src/com/eps/william/androint/AndroIntActivity.java <source top>/out/target/common/R/com/eps/william/androint/R.java
接著用 javah 來產生 .h file , command 如下:
javah -jni -classpath ../bin com.eps.william.androint.AndroIntActivity
經過測試 ,沒有問題 , 只是..... 一切都不自動 , 需要手動產生, 並且還要先編譯 java 程式 , 然後手動產生 .h file , 然後 修正 .c file , 最後在 Android.mk 中加入 .so 的 make 部份 . 一點都不優......
經過幾天的 study , 修改了一下 Android.mk 內容 , 讓整個 make 過程中自動產生 .h 然後接著 compile .c file 產生 .so ...... , 修改後的 Android.mk 如下:

因為 Android 的 make rules 太複雜 ,並且支援 make -jN , 所以乾脆獨立出來 build so file . 所以會看到 "@$(MAKE) -C $(JNI_LOCAL_PATH) -f Makefile.jni local_jni " 的字串 , 其中 Makefile.jni 如下:
