import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends ActionBarActivity {

    static {
        try {
            System.load("native/libkdu_jni.so");
        } catch (UnsatisfiedLinkError e) {
          System.err.println("Native code library failed to load.\n" + e);
          System.exit(1);
        }
      }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    @Override

        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);

LogCat 错误:

我应该把这个文件夹放在哪里？

Answer 1

试试这个:

System.loadLibrary("kdu_jni");

loadLibrary()实际上是从ape的lib/加载的。另外，您不需要指定“lib”和扩展名“so”。

希望这有帮助。
