情景1： 测试程序A与被测试程序B
程序A：
public class TestA extends ActivityInstrumentationTestCase2{
static Class<?> launcherActivityClass;
static {
try {
launcherActivityClass = Class.forName("com.ymf.a.ShareA");
}catch (ClassNotFoundException e) {
throw new RuntimeException(e);
}
}
@SuppressWarnings("unchecked")
public TestA() {
super("com.ymf.a", launcherActivityClass);
}
@Override
protected void setUp() throws Exception {
super.setUp();
getActivity();
}
protected void tearDown() throws Exception {
super.tearDown();
}
public void testAA(){
try {
Class c = Class.forName("com.ymfa");
Field f = c.getDeclaredField("test_var");
Integer i = (Integer) f.get(null);
Android.util.Log.i("TAG",i+"");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchFieldException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
程序B：
public class ShareId_B extends Activity {
static int test_var = 10;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
情景2： 两个独立的APK，配置成同一个进程
A：
public class Ymf {
public static int a = 10;
}
B：
public class ShareId_B extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//PathClassLoader loader = new PathClassLoader("/data/app/com.ymf.a.apk", ClassLoader.getSystemClassLoader());
Context context = null;
try {
context = createPackageContext("com.ymf.a", Context.CONTEXT_INCLUDE_CODE|Context.CONTEXT_IGNORE_SECURITY);
} catch (NameNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Class c = null;
try {
c = context.getClassLoader().loadClass("com.ymf.a.Ymf");
android.util.Log.i("TAG",context.getClassLoader().toString()+"");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Field f = null;
try {
f = c.getDeclaredField("a");
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (NoSuchFieldException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int o = 0;
try {
o = (Integer) f.get(null);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
android.util.Log.i("TAG",o+"");
