Question

我正在尝试制作.so文件，但它会出现以下错误 ndroid-ndk-r9\ndk-build.cmd all make: Nothing to be done for全部”。 `

在jni文件夹中我有所有这些文件

intarray.c
intarray.h
jni_setup.h
sqlite_extension_example.c
sqlite3_wrap_manual.c
sqlite3_wrap_manual.h
sqlite3.c
sqlite3.h
sqlite4java-android.cpp
Android.mk

直到现在我能够在obj文件夹下生成.a文件，即libsqlite3.a

以下是代码

package com.example.sqlite4;

import java.io.File;
import java.util.ArrayList;

import com.almworks.sqlite4java.SQLiteConnection;
import com.almworks.sqlite4java.SQLiteStatement;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.Toast;

public class MainActivity extends Activity {
ArrayList<String> orders = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    try {
        System.loadLibrary("sqlite4java-android");
        SQLiteConnection db = new SQLiteConnection(new File("/storage/sdcard1/sk.db"));
        db.open(true);
        SQLiteStatement st = db.prepare("select C0,C1,C2,C3,C4 from T0 where C0= ?");
        try {

            String minimumQuantity = "'2907'";
            st.bind(1, minimumQuantity);
            while (st.step()) {
                orders.add(st.columnString(0));
                orders.add(st.columnString(1));
                orders.add(st.columnString(2));
                orders.add(st.columnString(3));
            }
        } finally {
            st.dispose();
        }
        db.dispose();
    } catch (Exception e) 
    {
        e.printStackTrace();
    }

    Toast.makeText(getBaseContext(),orders.toString() , Toast.LENGTH_LONG).show();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
}

这是日志
