android将lib库打包成apk安装

package com.android.mylib; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class MyLibActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); int x = 55; int y = 8; int z = 0; System.loadLibrary("test"); z = testme(x, y); tv.setText(x + "+" + y + "=" + z); setContentView(tv); } public native int testme(int x, int y); }
