自定义的Java文件SQLiteConnection       https://www.dropbox.com/s/5ex6u9rzkwb7kqq/SQLiteConnection.java 错误线路上无。 160

Custom Java file SQLiteConnection https://www.dropbox.com/s/5ex6u9rzkwb7kqq/SQLiteConnection.java error on line no. 160

下面是从哪儿我编写，并建立了二进制的libsqliteX.so文件中的http://www.sqlite.org/android/tree?ci=trunk&re=jni|src/org/sqlite/data&expand

Here is the source cpp files from where i have compiled and created the binary "libsqliteX.so" file http://www.sqlite.org/android/tree?ci=trunk&re=jni|src/org/sqlite/data&expand

我的.so文件 https://www.dropbox.com/s/d0u5pyhke54tcd6/ libsqliteX.so

所以我觉得我有在本地方法来修改，以解决此问题。

so i think i have to modify in the native method to resolve this problem

static jboolean nativeHasCodec(JNIEnv* env, jobject clazz){
#ifdef SQLITE_HAS_CODEC
return true;
#else
return false;
#endif
}

下面是CDT全球BUILD CONSOLE

所以，我认为。所以是正确生成

so i think .so was generated properly

推荐答案

我已经加入解决了这个问题，我的自我

I have resolved this issue my self by adding

System.loadLibrary("sqliteX");

要在那里它们被创建的每个方法

To each method where they are created

是这样的：

public HashMap<String, ArrayList<String>> word_quiz(String qry) {
    System.loadLibrary("sqliteX");
    ArrayList<String> list1 = new ArrayList<String>();
    ArrayList<String> list2 = new ArrayList<String>();
    SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(DB_PATH+ "/sk1.db", null);
    Cursor mcursor = db.rawQuery(qry, null);
    try {
        mcursor.moveToFirst();
        do {
            list1.add(mcursor.getString(0));
            list2.add(mcursor.getString(1));
        } while (mcursor.moveToNext());

    } catch (IndexOutOfBoundsException e) {
        if (MainActivity.logcat_status) {
            Log.e("Error", e + "");
        }
    }
    mcursor.close();
    mcursor = null;
    HashMap<String, ArrayList<String>> final_list = new HashMap<String, ArrayList<String>>();
    final_list.put("list1", list1);
    final_list.put("list2", list2);
    db.close();
    return final_list;

}

现在它的做工精细

我想我也可以用一个构造函数加载库sqliteX

I think I can also use a constructor to load the library "sqliteX"

谢谢你们的考虑我的问题：）

Thanks guys for considering my question :)
