java - 更改包名时找不到 native 方法

Question

在我的项目中，当我更改包名称时，出现以下错误。我上网但没有有用的数据。在某些情况下，我发现我的方法不应该是静态的，当我删除静态时它规定该方法必须是静态的。任何解决这个问题的建议提前致谢这是我的错误:

未找到 native 方法:

这是我的代码:

public class JNIServer {
final static String tag = JNIServer.class.getSimpleName();

/* unfortunately Runtime.availableProcessors() returns only the number of online cores */
public static native int get_number_of_processors();

private static native int native_run_server(int game_mode, int field_size_x, int field_size_y, int ki_mode, int ki_threads);

private static native int native_resume_server(
        int field_size_x,
        int field_size_y,
        int current_player,
        int spieler[],
        int field_data[],
        int player_stone_data[],
        int game_mode,
        int ki_mode,
        int ki_threads);


public static void runServer(Spielleiter spiel, int game_mode, int field_size, int ki_mode) {
    int ki_threads = get_number_of_processors();

    if (spiel == null)
        native_run_server(game_mode, field_size, field_size, ki_mode, ki_threads);
    else {
        int player_stones_available[] = new int[Stone.STONE_COUNT_ALL_SHAPES * 4];
        int i, j;

        for (i = 0; i < 4; i++)
            for (j = 0; j < Stone.STONE_COUNT_ALL_SHAPES; j++)
                player_stones_available[i * Stone.STONE_COUNT_ALL_SHAPES + j] = spiel.get_player(i).get_stone(j).get_available();

        native_resume_server(
                spiel.m_field_size_x,
                spiel.m_field_size_y,
                spiel.current_player(),
                spiel.spieler,
                spiel.get_game_field(),
                player_stones_available,
                game_mode,
                ki_mode,
                ki_threads);
    }
}

static {
    Log.d(tag, "loading server.so");
    System.loadLibrary("server");
}

}

为什么你到处使用native关键字？这应该意味着某些东西是用另一种语言实现的，但这里的情况似乎并非如此，因此会导致此错误。
